List of Shocking Evidence Documenting a Pattern of Negligence by NRC and Exelon at Limerick Nuclear Plant










June 2010

  • NRC issued its “Waste Confidence Decision and Temporary Storage Rule”
  • NRC never waited for or required proven failsafe spent fuel storage before licensing  Limerick or to relicense the age-degraded nuclear plant



  • GE Hitachi notified NRC that Limerick’s Mark II Boiling Water Reactors (BWRs) might not shutdown under certain circumstances



  • NRC and Exelon’s lobbying arm, the Nuclear Energy Institute (NEI), issued an industry-friendly plan for reviewing License Renewal Applications


1-1-11 to 12-31-11

  • NRC cited Exelon for “Impeding the Regulatory Process”

Annual Assessment  Letter for Limerick Generating Station, 3-5-12



  • Unit 2 recirculation pumps tripped off-line



  • A tripped switch caused the Unit 2 Primary Isolation Valve to close during refueling



  • Fukushima’s disaster and meltdowns began, raising global human radiation dosage levels from 360 millirems/yr to 620 millirems/yr, according to the NRC



  • NRC cited Limerick with a “white” violation (noncompliance of a legally binding requirement) for the breakdown of one of its water delivery systems



  • Unit 2 reactor tripped off-line due to turbine control trouble



  • Unit 2 was manually tripped off-line during start up activities.



  • Unit 1 tripped off line from 100% power



  • Exelon submitted Limerick’s License Renewal Application to NRC, without being required to update Limerick’s Severe Accident Mitigation Alternatives (SAMA)



  • Exelon had made changes to Limerick’s emergency actions without NRC approval which reduced safety



  • An earthquake originating in Virginia, struck Limerick Nuclear Power Plant and operators felt vibrations in Limerick’s control room,

Seismic monitors, inoperable for over a year, could not confirm the earthquake



  • “Enformable Nuclear News” reported that designers, operators, and regulators of nuclear power plants only plan for statistically probable events – thus not preparing for events that, though not probable, could raise risks if an accident does not play out as modeled


9- 2011 to 8-2012

  • NRC cited Exelon with violations associated with impeding the regulatory process at Limerick (NRC Integrated Inspection Report, Cover letter 2-5-13)



  • The AP mirrored a report done in March by MSNBC that ranked Limerick as the plant with the 3rd highest risk of being damaged by an earthquake (MSNBC used NRC data)



  • An 11,000 page records-request showed that NRC experts worried privately that nuclear plants needed stronger safeguards in response to their higher post- Fukushima earthquake risk assessments,

This finding by the Associated Press (AP) is important at Limerick due to its higher risks that were not accounted for in a GI-199 assessment for Limerick based only on  generic modeling, not Limerick-specific information



  • NRC held a public hearing about Limerick’s Environmental Impact Statement (EIS) in response to Exelon’s submission of Limerick’s License Renewal Application.

The stated premise  was to provide public input, but public input was completely dismissed when NRC issued its Final EIS, August, 2014



  • GE Hitachi repeated its 9-3-10 warning that Limerick’s Inherently defective GE Mark II Boiling Water Reactors (BWRs) may fail to to safely shutdown under certain circumstances,


10- 3-11 to 10-14-11

  • NRC conducted its “Generic Aging Lessons Learned (GALL) Audit” designed by Exelon’s lobbying arm, the Nuclear Energy Institute (NEI) to fast-track license renewal.


11-4-11 (The date listed on” NRC Findings for CY 2011 at Limerick generating Station”)

  • Failure to verify power availability necessary for station blackout recovery


11-7-11 to 11-10-11

  • NRC conducted a required site auditSite Audit” in response to Exelon’s 6-22-11 License Renewal Application



  • The Natural Resources Defense Council (NRDC) filed a petition requesting that Limerick nuclear plant risks be re-evaluated, due to Limerick’s outdated 1989 Severe Accident Mitigation Alternatives (SAMA)



  • NRC approved Exelon’s amendment request to substitute more frequent monitoring and other indications of reactor coolant system leakage for an inoperable monitoring system that was used along with:

             1) The Containment Atmosphere Gaseous Monitoring System

             2) The Primary Containment Pressure and Temperature Monitoring System

On 9-6-13, NRC issued a violation for inoperability of Limerick’s radioactive gas clean-up system, that was traced back to 10-26-10, which raised the public’s offsite radioactive gaseous effluent exposure for that period



  • In secret, NRC pared down evacuation plans and emergency drills near nuclear plants


12-31-11(The date listed on” NRC Findings for CY 2011 at Limerick generating Station”)

  • A relay in service 6 years beyond its vendor-recommended replacement date failed



  • NRC granted Exelon’s Limerick License Amendment to modify the Unit 1 safety limit minimum



  • The Nuclear Information and Resource Service (NIRS) and 37 co-petitioners joined the petition request by to NRC to expand emergency planning zones

On 4-9-14, NRC denied the expansion



  • An Instrument and Controls (I & C) technician accidentally entered a room with high radiation, posted as requiring a neutron radiation monitor, without one



  • NRC revised its regulations for license renewal applications that  helped fast-track the process without protections that the public felt were necessary

The changes were initiated by Exelon’s lobbying arm, the Nuclear Energy Institute(NEI)


February, 2012

  • In response to NRDC’s petition, NRC held a hearing



  • NRC ordered the installation of reactor vents “without delay” when it knew that vents without filters cause extreme public radiation dosage due to vent-expelled radiation

NRC later granted Exelon’s request to delay vent installation until 2018 (Unit 1)and 2019 (Unit 2)



  • NRC issued its order to modify licenses with regard to requirements for Mitigation Strategies for Beyond-Design-Basis external events



  • NRC granted Exelon an amendment that changed the method of calculating core reactivity from “predicted versus monitored control rod density”

NRC stated it had reasonable assurance that public health and public safety would not be endangered



  • 15,000 gallons of radioactive water spilled into the Schuylkill River, but neither Exelon nor NRC alerted water companies or the public to take protective action and the public never knew it occurred until the local newspaper 23 days later, on 4-13- 12


4- 4-12

  • The spill had not yet been made public, when eleven days later, a high level of Iodine 131 was found in the Philadelphia Water Department’s water.
  1. Iodine 131 is a signature fission byproduct of Limerick nuclear plant
  2. Exelon denied it was from Limerick


4- 4-12

  • The Atomic Safety and Licensing Board (ASLB) allowed the NRDC’s SAMA challenge  to move forward



  • Limerick’s 15,000 gallon radioactive water spill into the Schuylkill River was announced in the Mercury

People had been denied the option to switch to bottled water, especially for infants, the sick, or the elderly for over three weeks, and elevated levels of iodine had been discovered in Philadelphia’s water supply eleven days after the spill



  • A false alarm indicated a trip of the reactor enclosure ventilation system, the cause of which could not be determined



  • Then-chairman of the NRC publicly revealed that NRC uses a computer model called ‘pencil whipping’ so any nuclear plant, no matter how degraded, looks “good to go” for continued operations.


June, 2012

  • the U.S. Court of appeals for the D.C. Circuit vacated (erased) the NRC’s 2010 Waste Confidence Decision and Temporary Storage Rule, ordering NRC to issue no license renewals pending resolution of waste storage issues



  • For six months , Exelon failed to recognize the condition that led to a valve failure
  1. During a test, a water flow valve failed to open following a loss of water signal and failed again when the test was repeated
  2. The condition had existed, but not been recognized since 11-30-11



  • Eight years past their vendor-recommended lifetime, degraded relays caused an unplanned shutdown that could have led to core damage.



  • Operator failure to follow an alarm within 15 minutes delayed power reduction for an hour and 49 minutes, resulting in an unplanned shutdown
  1. Circumferential fatigue cracks were observed around the weld toe
  2. Limerick’s Unit 1 reactor has acrack in a weld joining an inlet riser to two jet pumps and the transition piece



  • Three years of inadequate preventive maintenance resulted in a transformer explosion in the plant’s control structure, adjacent to the control room, necessitating a manual scram due to loss of power to main generator cooling water pumps, the 4th scram since 2010



  • Unplanned shutdown & outage due to leaking safety/relief valve & hydrogen leak



  • Exelon was cited for its 9-month failure to respond to a Unit 1 reactor alarm for ‘depressurization and IA dryer filter’



  • Unit 2 reactor shutdown during startup was caused by a reactor water level transient that caused malfunction of the turbine valves



  • NRC granted Exelon’s request to eliminate the test to demonstrate age-degraded equipment operability from Limerick’s License renewal Application

NRC allowed Exelon to eliminate Commitment No. 46, which was the requirement for the test



  • NRC joined Exelon in Exelon’s appeal to stop NRDC’s Petition to require Exelon to include an updated SAMA as a part of Limerick’s License Renewal Application,

The 5-member Commission agreed, contending that NRDC had launched an “impermissible collateral attack on our regulations,”



  • Failure to adequately evaluate the voltage to safety equipment, which could have resulted in loss of coolant or fire. Failure in real time could result in core damage.



  • A 3-month NRC Inspection of Units 1 and 2 that began on 10-1-12 listed the following  summary of Limerick deficiencies:
  1. Failure to administer an NRC Annual Operating Test Simulator Scenario Re-examination that met procedural requirements
  2. Failure to revise EDG Tank Cleaning Work Instructions
  3. Failure to follow Radiation Protection Procedures for personal protection
  4. Inoperable Primary Containment Isolation Valves
  5. Redundant Reactivity Control System setpoint drift
  6. Inoperable Isolation Instrumentation
  7. Three Main Steam Isolation Valves failed the Surveillance Test
  8. Exelon made changes to the Emergency Plan without NRC approval


2000 to the end of 2012

  • Limerick reported 114 violations from 2000 to the end of 2012
  1. Charlotte Observer, !0-16-13,  Business National News, 10-15-13
  2. NRC’s inconsistent enforcement shows extraordinary differences among U.S. regions.
  3. Our concern is that, based on the NRC and Exelon e-mailed report we received from NRC when we questioned NRC about the quake that hit Limerick on 8-23-11, it appears that the significance of violations may be substantially underplayed in Exelon’s records
  4. Based on NRC Safety Inspection Reports, it appears that NRC’s process of rating violations is significantly impaired by NRC’s pre-determined objective to keep Limerick operational by lessoning the appearance of violations that could significantly impact plant stability



  • Exelon did not verify that adequate voltages would be available to safety-related equipment during a design basis loss-of-coolant accident

Exelon’s License Renewal Application for Limerick contained many similar deficiencies as well as flawed assumptions.


1- 30-13

  • NRC granted Exelon’s request to withhold from public disclosure: “Standard Practice Procedure Plans and Updated Foreign Ownership Control or Influence Package” (Executed by Global Nuclear Fuel-Americas, LLC (GNF-A)



  • NRC closed the issue of Limerick’s degraded Motor Operated Valve (MOV) System that broke down on 5-23-15 while experimentation to keep it operational continued



  • The Atomic Safety and Licensing Board (ASLB) referred NRDC’s petition requesting an updated SAMA for Limerick to the 5-member NRC Commission for final determination



  • NRC’s Commitments Audit revealed a pattern of inexplicable negligence in the area of Exelon’s Preventive Maintenance, especially in regard to the inoperability of Limerick’s seismic monitoring system



  • NRC issued Amendments No. 209 (Unit 1) and 170 (Unit 2) re: Relocation of Technical Specifications for Motor-Operated Valve Thermal Overload Protections

This change charts new territory for unknown risks



  • Beyond Nuclear’s Reactor Oversight Project Director and 22 public advocacy groups joined together to request that NRC revoke the operating licenses for all nuclear plants operating with the defective GE Mark I and Mark II Boiling Water Reactors (BWRs) in the U.S.
  1. Limerick has two defective Mark II BWRs
  2. NRC refuses to test the reactors using the surveillance capsules that the 2013 NRC chief said were in Limerick’s reactors.



  • Two RP technicians were accidentally locked temporarily in a Unit 2 area known to have high radiation risk

The workers were freed without mishap, but it is worth noting that this level of risk exists



  • Aside from poor maintenance there was no explanation for the unexpectedly low condition of Unit 1 battery chargers



  • NRC granted Exelon’s request to change the Core Operating Limits Report for Limerick Generating Station Unit 1, Reload component removal 14, Cycle 15, Revision 10



  • NRC issued a “Withdrawal Notice” for “Reporting Procedure for Mathematical Models Selected to Predict Heated Effluent Dispersion in Natural Water Bodies.” (Regulatory Guide (RG) 4.4)



  • An engineering recommendation that had been made on 10-26-10, but overlooked was made again, to test the Unit 2 Primary Containment Instrument Gas (PCIG) check valve, because there was a problem.

This recommendation continued to be overlooked until 9-6-13 when it was discovered that off-site radiation doses were raised due to the failure of the valve



  • A Former NRC Chairman said, in light of what he learned from Fukushima, the public has no protections and no U.S. nuclear plants are safe

Predictably, the president and chief executive of Exelon’s lobbying arm, the Nuclear Energy Institute (NEI) asserted that “U.S. nuclear Energy facilities are operating safely. That was the case prior to the Chairman’s tenure, the case during his tenure, and it is still the case today.”



  • A reactor automatically shutdown due to improper procedures and lack of ordinary foresight



  • It was reported in an interview, that the average nuclear plant has 6 guys on Ebay trying to buy old parts.
  1. The reason is that if they put a new part in, and it isn’t like the original, they have to go to the NRC and ask permission. Old parts are in their warehouse so when a part breaks down, they can replace it “in kind” instead of getting something newer or better.
  2. Could it be possible that the 16 years of refurbished equipment malfunctions mentioned for date 8-21-13 resulted from this practice?



  • NRC approved nuclear industry-friendly alternatives and weakened Post-Fukushima Near Term Task Force Recommendations instead of enforcing them,
  1. It is of little benefit to the public to have pro-nuclear industry groups driving the NRC policies which expedited Limerick license renewal
  2. NRC is refusing to regulate Limerick on behalf of protecting people and the environment, in favor of an industry that has shown that it is not interested in public health and safety



  • 6-month failure of Emergency Diesel Generator (EDG)



  • Ventilation System Trip due to the degraded performance of the Primary Containment Isolation System’s reactor enclosure equipment compartment exhaust flow transmitter



  • Safe-shutdown switches for Units 1 & 2 sustained fire damage due to poor preventive maintenance

The fire brigade and fire equipment delivery to the spray pond pump house was delayed



  • NRC granted Exelon’s amendment change for Core Operating Limits Report For Limerick Generating Station Unit 2, Reload 12



  • NRC released a deceptive newspaper public statement: “NRC Wants Upgraded Vent System” as if vents without filters offer the public protection.
  1. This was a degraded version of NRC’s 1980 post-TMI recommendation to install filtered vents at Limerick, which NRC never enforced
  2. This repeat of NRC’s 3-12-12 recommendation, reveals that NRC is more concerned with appearing to protect people than in actually protecting them



  • NRC cited “Improper procedures, performance deficiency, and poor decision making” as causes for turbine and control valve stoppage causing Unit 2’s unplanned automatic reactor  shutdown



  • Depressurization in Unit 1 due to a service air compressor trip caused by reintroducing a previously failed circuit board



  • Failure of the transformer automatic voltage changer



  • 9 months of human error led to repeat inadvertent depressurization of Unit 1 reactor.



  • NRC’s Petition Review Board (PRB) recommended dismissal of a public request by Beyond Nuclear and 22 other public advocacy groups to close all nuclear plants operating with defective GE Mark I & II BWRs.
  1. The dismissal was made without answering questions and addressing charges
  2. Petitioners did not give up, as shown on 9-30-13



  • Limerick Units 1 & 2 exhibited four or more of the 11 risk factors that qualified it for early closure in a report by Mark Cooper, senior fellow for economic analysis, Institute for Energy and the Environment in his report, “Renaissance in reverse: Competition Pushes Aging U.S. Nuclear Reactors to the Brink of Economic Abandonment” He noted:
  1. The death of Limerick’s large planned power uprate project
  2. Risk factors based on ratings by Moody’s, UBS, and Credit Suisse
  3. Although this is not a prediction, keeping aging nuclear plants on-line if they need repairs or retrofits does not make economic sense and Limerick is undergoing major repairs and experiments, especially on its core water delivery system that no longer operates as a motor-driven system.



  • NRC announced its password-protected portal

For, it says, licensee contractors’ submittals that support post-Fukushima Near Term Task Force recommendations



  • The Attorneys General of New York joined in an effort to stop NRC from erasing all record of a judicial ruling that the public has a right to intervene before major amendments are granted to a nuclear plant’s operating license



  • Incorrect amount of chemical added to Emergency Diesel Generator jacket water



  • A defective Redundant Reactivity Control System (RRCS) Analog Trip Module (ATM) board rendered the Unit 1 RRCS inoperable



  • The defective ATM board was replaced with a refurbished board and returned to service, however within 24 hours, the channel reading was drifting again



  • The ATM malfunction did not actuate the Unit 1 Residual Heat Removal (RHR) heat exchanger bypass valve control, requiring further troubleshooting.



  • 16 years of refurbished equipment malfunctions took seven days, from 8-14-13 to 8-21-13, to recognize



  • NRC notified Exelon that there was deficiency in the Motor Operated Valve (MOV) system in nuclear plants like Limerick which was identified in 1985

Known as “hammering”  the defect had already damaged Limerick’s MOV system, which is undergoing a series of new experiments



  • The unnoticed inoperability of Limerick’s radioactive gas clean-up system for almost 3-years, was finally noticed
  1. Beginning on 10-26-10, inoperability raised the public’s offsite radioactive gaseous effluent exposure
  2. Two years before the Atomic Energy Commission (AEC) issued Limerick’s construction permit, which was 12 years before In NRC issued the license for Unit 1, the AEC stated that Limerick’s “estimated doses from gaseous effluents are much higher than those considered acceptable by the staff. With the estimated outage of the gas clean-up system, the air immersion dose to an individual at the site boundary will be about 480 millirems/year” (AEC’s 1972 Limerick Environmental Impact Statement, EIS).
  3. Note: radiation does not stop at Limerick’s boundary.
  4. Limerick’s radioactive gas release report from 2011 had an uncertainty rate of 15.7% – 36.6%.
  5. The AEC’s estimate of 480 millirems /yr for Limerick radiation, with outage of its gas clean-up system, may or may not be accurate.
  6. According to NRC’s estimate, Chernobyl raised the global background radiation doses of human exposure from 100 to 360  millirems/yr., Fukushima’s meltdowns that started on 3-11-11, raised the dosage to 620 millirems/ year , and at Limerick, on top of that, we have high off-site gassing
  7. Exelon deceptively states that all sources of radiation are the same, however, nuclear plants produce radionuclides unknown in nature, which may have unknown additive, cumulative, and synergistic effects



  • Reintroducing a refurbished circuit board caused a service air compressor trip depressurizing Unit 1



  • Beyond Nuclear and 22 other public advocacy groups filed a petition before the NRC’s Petition Review Board (PRB) as part of Beyond Nuclear’s “Freeze Our Fukushimas” campaign.
  1. The petition charged that NRC’s post-Fukushima actions ignore the dangerous vulnerabilities of U.S. nuclear plants currently operating with GE’s inherently defective Mark I and II Boiling Water Reactors (BWRs)
  2. Beyond Nuclear suggested that while Japan contemplated how to freeze a wall 90 feet into the earth to contain Fukushima’s radioactivity, NRC’s focus should be on permanently freezing the operation of all GE Mark I and II BWRs nuclear plant operations.
  3. On 2-26-14, Beyond Nuclear initiated a  massive public advocacy group effort to request requiring the installation of severe-accident-capable containment vent systems in conjunction with external, engineered, radiation filter installation at nuclear plants (including Limerick)



  • NRC defined the primary responsibility for nuclear plant safety and security as resting with the licensee, in Limerick’s case Exelon, and NRC minimized its own role by stating that NRC simply has oversight
  • This announcement compounds lax public protections:
  1. NRC defines its Reactor Oversight Program (ROP) as ‘documenting’ risks with enforcement essentially an ‘interpretation’ of regulations.
  2. The clarification was made in an NRC address to interested nuclear industry stakeholders anticipating NRC’s cessation of functions if there was a government shutdown
  3. The NRC / Exelon relationship is a huge problem, because 90% of NRC’s nearly $1 billion budget is paid by the nuclear industry it supposedly regulates and there seems to be no mechanism for enforcement
  4. As was shown at Fukushima, industry self-reporting is unreliable due to self-interest



  • A congressional study pointed to inconsistencies in NRC’s enforcement of violations at power plants throughout the U.S.



  • It was reported that reactor water monitoring systems do not work correctly and it is very difficult to operate a nuclear power plant with any degree of certainty.

When one of the reactors has an emergency shutdown, operators simply do not know if the reactor has enough water to keep it cool(Fairewinds Energy Education podcast discussion between a nuclear researcher and an experienced nuclear engineer)



  • The Office of the Inspector General (OIG) announced that NRC was inadequately enforcing regulatory requirements of active component aging and NRC’s management was not focused or coordinated

Active components are valves, motors, fans, electrical relays, etc., whereas passive components include pipes, supports, and tanks



  • NRC held a short “affirmation hearing” that all five members of the federal NRC commission attended, and where they all affirmed their agreement to refuse NRDC’s petition for an updated Limerick SAMA
  1. In 1996, NRC amended its regulations to require SAMA analysis for all new nuclear plants, specifically exempting Limerick from needing another for re-licensing
  2. NRC argues that Limerick’s SAMA that was done in 1989 doesn’t have to be updated
  3. However, Limerick’s SAMA was court-ordered, not voluntarily produced
    • In 1981, before Limerick construction was complete, Limerick Ecology Action (LEA, predecessor of ACE) sued NRC for, among other things, not considering alternatives for Limerick.
  • NRC did not halt construction when LEA filed the suit in court
  • NRC continued construction and dragged out the court case until NRC had licensed Unit 1(1984) and Unit 2 (1989)
  • NRC was ordered to produce a SAMA as part of the court’s judgment against NRC to increase public protection
  1. NRC completed Limerick’s court-ordered SAMA in 1989
  2. Produced under court order as an after thought to licensing Limerick, NRC’s Limerick SAMA may not have been produced as thoughtfully and protectively as it might have been, and so might need updating, given the new understandings we have gained about the risks associated with Limerick operations since Fukushima.



  • Although, immediately after Fukushima’s nuclear disaster, NRC explained that filtered vents offer the public better protection than vents alone as a post-Fukushima upgrade, in November 2013, NRC caved in to industry pressure and eliminated filters, due to industry costs
  1. Then, NRC directed utilities to follow the guidance of Exelon’s lobbying arm, the Nuclear Energy Institute (NEI) and install vents only, classifying that as, “compliance”
  2. NEI is the very powerful lobbying Arm of the nuclear Industry (not a government-appointed regulatory agency)
  3. On  3-12-12, NRC had ordered the installation of reactor vents “without delay”
  4. On 6-12-13, NRC released a deceptive newspaper public statement: “NRC Wants Upgraded Vent System” as if vents without filters was a good thing and as if upgrades were being installed in a timely fashion.
  5. On 2-26-14, Beyond Nuclear initiated a  massive public advocacy group effort to request radiation filters on vent installations at nuclear plants (including Limerick)



  • 6-month emergency diesel generator leak due to critical component failure of a pipe fitting that leaked for from Nov. 2012-May, 2013, was discovered



  • Beyond Nuclear initiated a massive public advocacy group effort to request that the Office of Inspector General (OIG) investigate the NRC Commissioner’s 3-19-13 majority vote that resulted in the 6-6-13 Order that ignored the NRC’s  own technical staff’s recommendation to require the installation of severe-accident-capable containment vent systems with radiation filters at nuclear plants (including Limerick)
  1. Although filtered vents are being mandated in other countries, the U.S. has allowed Exelon to stall until 2018 and 2019 for its vent-only installations
  2. Limerick eliminated filter installation to save itself money, even though filters protect humans and NRC originally recommended them as cost-justified expenditures (source: NRC’s Backfitting cost-justified Substantial Safety, draft)



  • Unit 1 Rapid Plant Shutdown into hot shutdown due to an Electro-Hydraulic Control (EHC) System failure

This caused the inability of all Low Pressure Turbine Intercept Valves to close



  • Mercury report: “‘Scram’ advances Limerick nuke plant refueling”



  • NRC released the report of the 3-13-15 meeting between NRC staff and Exelon’s lobbying arm, the Nuclear Energy Institute (NEI) to discuss current License Renewal Topics



  • NRC denied expansion of nuclear power plant Emergency Planning Zones (EPZs) requested by the NIRS petition



  • Mercury report: “NRC rejects bid to expand evac zones around nuclear plants”



  • NRC released its deceptive 2013 assessment of Limerick in the Mercury with the headline, “NRC: ’green’ rating for plant in 2013”
  1. NRC deceptively chose the color green, which indicates a violation,knowing that people are conditioned to think green means safe.
  2. People are unaware that compliance is not a matter of physical adherence to a standard, but instead, means the data base record shows that no physical violation exists because the record of the regulation, in its original form, has been replaced by the regulation without the requirement, while the violation still exists physically on-site
  3. Green violations blanket many Limerick safety defects, such as accidents that can lead to core damage and Limerick’s defective GE Mark II Boiling Water Reactors, which all contribute to Limerick’s continual state of high risk



  • NRC issued its deceptive post-Fukushima seismic evaluation of Limerick based on generic modeling which hid Limerick’s real earthquake risks



  • Digital First Media post: “NRC Ruling on Evacuation Planning Fails the ‘Shadow Test’”



  • Mercury report: “De-commissioning fund yields little consequences for Exelon”
  1. For years, Exelon substituted its own formula for setting aside funds for decommissioning, which saved Exelon money
  2. Part of the resulting shortfall of millions of dollars has been assigned to ratepayers



  • NRC issued a revision of its “Design Spectra for Seismic Design of Nuclear Power Plants”
  1. NRC stated that it was issuing this revision without a public comment period because there were only minor staff changes and the NRC staff considers this approach acceptable for defining response spectra for the design of nuclear power plants
  2. Limerick, however is unique, with a set of unique seismic markers that may not be in the guide
  3. This guide is not a rule and does not require equipment upgrades, because the nuclear industry fought against upgrades due to costs, even though NRC said they offered cost-justified public protection



  • Mercury report: “NRC Mum About Security Problem at Limerick Nuclear Plant”



  • Emergency Diesel Generator ‘D14’ cylinder liner cracking and leakage was observed during startup after  2-year outage



  • NRC announced its “Waste Confidence Rule” which fast-track Limerick license renewal and simply directed Limerick to store all its waste on-site despite growing evidence that none of NRC’s assumptions about the nuclear industry’s ability to handle nuclear waste work:

Nation-wide evidence suggests that NRC’s mandate for Limerick to store high level radioactive waste on-site is no solution for Limerick:

  1. In 2014, the nation’s only underground nuclear waste repository was forced to close. A storage container burst, contaminating the facility and 22 workers. State and DOE officials were forced to pay $74 million in settlements for dozens of permit violations.
  2. On 10-14-15, an underground fire that began in 2010, smoldered and spread to within 1,000 ft. from uncontained nuclear waste.Repeated appeals to Federal, Missouri and Environmental Protection Agency, were ignored as of that date
  3. On 10-26-15, a soundless 40-second video was turned over to state officials showing bursts of white smoke and dirt flying from several explosions on 10-18-15 from the nation’s first federally-licensed low-level radioactive waste dump in the Nevada desert.Opened in 1962, its license was suspended in the 1970s for mishandling shipments of material that were buried but exploded and burned, as shown in the footage. The nuclear dump has not been safely brought under control since its shutdown in 1992



  • The Mercury reported that in September, Exelon would contest the NRC’s issuance of a “greater than green” violation regarding Limerick security.



  • NRC issued Limerick’s deceptive “Final Environmental Impact Statement” (EIS), one of the last steps in license renewal that resulted from NRC’s allowing public input, but excluding public input from influencing NRC’s issuance of Limerick’s EIS  
  1. Ignoring publicly presented evidence, NRC stated that Limerick’s Environmental impacts were small
  2. The scope NRC’s EIS was extraordinarily narrow and NRC defined the environmental parameters to exclude many factors commonly considered important l by the millions of people living within Limerick’s evacuation zone


10-1-14 to 12- 31-14

  • NRC stated in its Inspection Report, that it “verified Limerick’s ‘Evacuation Time Estimate’ (ETE) updates”
  1. NRC made a reference to the ETE in a sentence but has not, so far, acknowledged reading and analyzing it
  2. It is worrisome that NRC defined “verification” in Limerick’s Commitment Audit (2-27-13) as a search of Limerick’s database using key words. Verification should include reading the ETE to verify that it is workable, which it is not



  • 100-gallons of chlorine leaked into the Schuylkill River from a faulty valve

A second chemical was added, to try to neutralize the chlorine



  • Mercury article: “Limerick nuke plant leaks 100 gallons of bleach in to the Schuylkill River”



  • NRC relicensed Limerick without the backing of many experts and the public, whose concerns regarding safety and environmental protections were dismissed
  1. Granfathered defects include Limerick’s inherently defective BWRs, a motor-operated core water delivery system that is no longer motor-operated and is the subject of experiments, no Limerick-specific reevaluation of Limerick’s earthquake risks, no updated SAMA, no test of age-degraded equipment, and a host of exemptions for systemic deficiencies
  2. Flawed theories about high-level radioactive waste (spent fuel) have been proven wrong all along, yet NRC was able to license Limerick through the technicality of issuing its Waste Confidence Rule, without proof that it is failsafe.



  • Mercury article: “Limerick nuke plant’s license renewed for 20 years”



  • “The bottom line is, compliance with current licensing basis requirements has never been shown to be valid at any nuclear plant in the country, not at any plant at any time,”

Source: statement by a nuclear engineer with the Union of Concerned Scientists in “Aging Risk vs. Inherently Safe” article regarding extending the life of nuclear power plants



  • Exelon’s engineering team inspected its own experimental work to keep Limerick running and NRC issued its “evaluation” of the team’s inspection report in “Changes, Tests, Experiments, and Permanent Plant Modifications”



  • Mercury report: “Environmentalists Challenge Re-licensing of Limerick Nuke Plant”

The article highlighted NRDC action on behalf of public safety on 12-15-14, opposing NRC’s license renewal of Limerick without an updated SAMA



  • Mercury report: “Bomb Squad Called to Limerick Nuclear Plant, No Bomb Found”

Fortunately no bomb was found, but the fact remains that Limerick is a terrorist target



  • Surprisingly, instead of publishing Exelon’s request to Amend Amendment 174 in the Federal Register, as required, NRC posted it in the Mercury’s ‘Classifieds’ section, stating that it did so because this was an emergency and there was no time to post it in Federal Register.
  1. NRC stated that if it did not grant Exelon’s requested amendment, NRC would have to shut Unit 2 down for being in violation of regulations.
  2. The emergency was that Exelon could not meet an equipment installation date of 2-27-15, which it knew it needed to do when it asked for the Amendment that set the date that Exelon wanted amended again.



  • Submittal to NRC: ACE Objection to Exelon’s Requested Amendment of Amendment No. 174, Leak Detection System Setpoint and Allowable Value Changes”

NRC granted the amendment, allowing Unit 2 to operate in physical violation of regulations until spring refueling



  • Mercury report on Limerick accident: “Valve Leak shuts down Limerick nuclear plant”



  • Mercury report on Schuylkill’s insufficient water supply: “Exelon nuke plant seeks more Schuylkill River water during heat waves”

Limerick’s insatiable water use is a growing threat to the public health and safety in this time of global warming



  • Exelon declared an “alert” at Limerick due to a “small” fire which was, according to Exelon, in the reactor building and, according to NRC, in one of the security buildings.



  • Unit 2’s preplanned shutdown did not work, requiring an immediate manual full shutdown, or a shutdown of a shutdown.

It worked, but shows the constant gamble with safety at Limerick



  • NRC issued Limerick Amendment Nos. 216 (Unit 1)and 178 (Unit 2), approving  “Technical Specification Task Force (TSTF) Traveler TSTF-523, for “Managing Gas Accumulation In Emergency Core Cooling, Decay Heat Removal, And Containment Spray Systems”



  • Unit 2’s radiation levels rose due to the accidental overflow of radioactive liquid from a tank resulting in exposure and decontamination of personnel and accessible areas of Unit


7- 7 & 8 -15

  • Accidental drainage of 231 gallons of cask water “exposing fuel assembly tops”  because there were no directions to close the discharge valve after work was completed

Radiation rose until it was noticed by the RP technician, who alerted the floor manager, who noticed the water accumulating on the refueling floor.



  • “Town and Country” newspaper published the headline, “Montco Health Department to Distribute Free Potassium Iodide Tablets on Aug. 6



  • State officials identified trains called “oil bomb trains” as hazards that warranted updated emergency preparation (Mercury). The public objected to tracks running through Limerick’s site, 1/8 mile from the reactors



  • Two circulating water pumps tripped requiring power reduction



  • The Mercury reported, “Feds (NRC) halt study of cancer risks at 7 nuclear plants”
  1. Federal regulators (NRC) pulled the plug on a five-year study of the risk of cancer in communities around six U.S. nuclear plants and a nuclear fuel site.
  2. Cancer statistics document very high levels of cancer around Limerick



  • NRC approved Exelon’s relief request exempting Limerick’s pumps from  Inservice Testing (IST)
  1. This exemption excuses Limerick’s pumps from the new testing requirement of the American Society of Mechanical Engineers (ASME)
  2. NRC based its approval of the exemption on its conclusion that the alternative (no testing) will provide “an acceptable level of quality and safety” (the public’s definition of acceptable quality and safety may differ from NRC’s)



  • ACE filed an objection to NRC’s proposed deregulation of radiation exposure, contending that deregulation might remove accountability and liability for routine and accidental radiation releases from Limerick Nuclear Plant.
  1. At issue was NRC’s proposal to claim that radiation exposure is beneficial to humans
  2. However, some radionuclides produced by Limerick’s fission process are man-made and not found in nature, like Iodine 131 and Strontium-90 and the effects of Limerick’s radiation are not known, nor is the cumulative, additive, and synergistic effect on health fully understood


  • NRC issued a Limerick violation for inadequate procedures resulting in exceeding structural and seismic concrete block wall adequacy for storage of Emergency Diesel Generator switchgear, circuit breakers, and ground trucks
  1. This was more than minor because it interfered with equipment availability for preventing core damage in an emergency
  2. NRC reviewed Exelon’s responses regarding Exelon’s response to this violation



  • A fleeting equipment malfunction caused an unplanned shutdown during startup.



  • Post-Fukushima, Limerick has not instituted NRC’s recommendations yet, and unlike Fukushima, Limerick is not situated beside an ocean, but has an anemic river augmented by the water pumped in from the Wadesville Mine Pit.
  1. Meanwhile, five years after its meltdowns, Fukushima officials haven’t stopped Fukushima from leaking.
  2. So officials have approved the activation of a one-mile long wall of refrigerated pipes dug 100 feet underground around Fukushima in the hopes that the soil around the plant can be frozen, confining radiation to Fukushima’s melted reactors
  3. If an accident happened at Limerick, the consequences to the Greater Philadelphia Region, Pennsylvania and the nation would be catastrophic, in terms of death, and/or  impaired health, loss of environmental resources and economic devastation,
  4. It hardly seems worth using Limerick as an energy source that has been proven to be such an enormous and unnecessary risk in terms of the safer, cheaper, cleaner alternatives  available currently that could form the basis for a more sustainable energy policy


“Bomb Trains” Should Not Travel 1/8 Mile From Limerick’s Reactors And Fuel Pools

“Bomb Trains” Should NOT Travel 1/8 Mile From Limerick’s Reactors And Fuel Pools

BE AWARE!  100-car crude-oil “bomb trains” regularly travel just 1/8 of a mile from Limerick Nuclear Plant’s reactors and fuel pools.

Frequent railroad transport of millions of gallons of explosive, flammable, hazardous crude-oil, only 1/8 of a mile from Limerick’s reactors and fuel pools, must be stopped immediately.   A “bomb train” derailment, explosion, and enormous fireball could burn for days in an unstoppable fire with days of thick black smoke which could trigger catastrophic multiple meltdowns.

Limerick, already a ticking time bomb + a bomb train derailment = catastrophic disaster!!!  

Millions of victims in the Greater Philadelphia Region would face unprecedented catastrophic consequences to our life, property, and the environment.  We could lose everything – homes, businesses, jobs, and health.  Drinking water for almost two million people (Pottstown to Philadelphia) would become too radioactive/toxic for safe use.  Long-term ecological damage would leave ghost towns that can’t be cleaned up safely. Our entire region could become a toxic wasteland for generations.

Victims would not be compensated adequately for losses, if at all.  Who would pay to deal with irreversible devastation from crude oil explosions/fire plus massive radioactive contamination from Limerick meltdowns?  Bottom line:  no one!

  • NOT insurance companies that refuse to cover radiological accidents
  • NOT Exelon, with its government guaranteed limited liability protection
  • NOT the railroad industry, already fighting for exemption from strict liability for derailment damages
  • NOT Pennsylvania, already burdened with an enormous deficit
  • NOT the federal government, already trillions of dollars in debt and totally dysfunctional

Train derailment disasters should be anticipated.  Occurring with more frequency, incidents occurred in over 250 municipalities – ProPublica data 2011-2014.  The worst caused widespread evacuation, death, destruction of buildings, and loss of electric and drinking water.  A 2015 accident in West Virginia proved safer trains and slower speeds aren’t the answer.

No matter what claims the oil, rail, or nuclear industries make, there is no emergency plan that could effectively deal with a disaster of this magnitude within 1/8 of a mile of Limerick’s reactors and fuel pools.  Fire fighters and emergency responders shouldn’t be expected to be on the front lines of such dangerous uncontrollable disasters.

Safe evacuation is an absurd illusion!  Limerick Nuclear Plant’s emergency and evacuation plans are fatally flawed and unworkable.  To understand why – review the 8-part ACE video-blog series on Emergency and Evacuation Plans for Limerick’s radioactive plume at   This should be a wake-up call, especially for all responsible for emergency and evacuation planning.

“Bomb trains” regularly traveling through the Limerick site dramatically increase Limerick’s already unacceptable risk for meltdowns from Limerick’s dangerously lax fire safety requirements, reactor shutdown problems, deteriorating aging equipment and systems, cyber attacks, and earthquake faults directly under reactors and fuel pools with increasing risk of earthquakes from fracking.   A crude oil disaster on the Limerick site could be caused by terrorism.  Even the attempted emergency response would increase opportunities for terrorism.

Crude oil bomb trains should not travel within 1/8 of a mile from limerick nuclear reactors and fuel pools, or anywhere on the site.   It’s far too risky!

Hoping it doesn’t happen is not the answer.   Denial allows extraordinary risks to continue and increase.

Officials have expressed concern but there has been no meaningful action to avoid such devastation.  We should not face such risk or put our fire fighters and first responders in such dangerous circumstances.

Catastrophic disasters from crude oil explosions and fires near Limerick Nuclear Plant can and must be prevented with foresight and political will to face and eliminate this unnecessary risk.  Willful blindness jeopardizes our future.

SPEAK UP NOW!  Demand that community leaders and elected officials get the crude oil “bomb train” route moved now, no closer than several miles outside the nuclear plant border.

“Bomb Trains” Should Not Travel Through The Limerick Site – Detailed Information

                                              BE AWARE!





  • Recent reports of crude oil derailment disasters show “bomb trains” keep exploding and turning into huge fireballs that burn for days, requiring miles-wide evacuations and resulting in devastating losses.
  • These unstoppable fires result in days-long thick black toxic smoke that are difficult, if not impossible to extinguish.
  • Crude oil trains travel frequently though Pottstown.  Officials expressed serious concerns. (8-18-15 AP).


  • Millions of people would lose their homes, businesses, and health.
  • Drinking water for almost two million people (Pottstown to Philadelphia) would become radioactive/toxic.
  • Long-term ecological damage would leave ghost towns that can’t be cleaned up safely.


  • NOT insurance companies that refuse to cover radiological accidents
  • NOT Exelon, with its government guaranteed limited liability protection
  • NOT the railroad industry, already fighting for exemption from strict liability for derailment damages
  • NOT Pennsylvania, already burdened with an enormous deficit
  • NOT the federal government, already trillions of dollars in debt and totally dysfunctional




Compiled By The Alliance For A Clean Environment (ACE)  November, 2015   (610) 326-2387  






Millions of people in the Greater Philadelphia Region face devastating risk from frequent railroad transport of millions of gallons of explosive, flammable, hazardous crude oil, only 1/8 of a mile from Limerick’s reactors and fuel pools.

Each shipment of explosive, flammable, hazardous crude oil traveling near Limerick’s reactors and fuel pools is estimated to contain:

  • 30,000 gallons in each rail car.  100 or more rail cars can contain over 3 million gallons.
  • Heat from the rupture and ignition of just one 30,000-gallon car can set off a chain reaction, causing other cars to explode, releasing a days-long fireball that is difficult, if not impossible to extinguish.  Basically, responders must let it burn out.

Train derailment disasters should be anticipated.  ProPublica data (2011-2014) reveals that incidents have occurred in over 250 municipalities.  Whole towns have already had to evacuate from crude-oil trains and fires.  No one should assume or suggest there will not be a crude-oil train derailment, explosion, and fire on or near the Limerick Nuclear property.

The worst of eight major crude oil train accidents and risks include:

  • A train derailment and explosion killed 47 and destroyed 30 buildings in Quebec.
  • 2,300 residents were evacuated in North Dakota. The fireball was observed several states away.
  • Serious crude-oil train derailments and fires are occurring with more frequency.  Many have occurred just since the beginning of 2015.
  • A fuel-oil train already derailed a few miles from Philadelphia.  Sixty-five tank cars bound for Philadelphia had loose, leaking, or missing safety components to prevent flammable, hazardous contents from escaping (Hazmat report – last two years).

Safer trains aren’t the answer.  A new train with a safer-design derailed in February 2015 in West Virginia, despite adhering to the speed limit.

  • Hundreds of families had to flee their homes in frigid weather
  • Burning continued for days
  • Drinking water and electricity were lost
  • Leaking crude oil poisoned the water supply
  • Fireballs erupted from crumbled tank cars, underscoring volatility of crude oil’s propane, and butane
  • Toxic water and dirt are difficult and very costly to attempt to clean up

Hoping it doesn’t happen doesn’t eliminate catastrophic risk!  Denial allows risks to continue and increase.

  • Richard Lengel, Pottstown’s Fire Chief, said in the Mercury 2-23-15, “If something catastrophic happens, there’s no municipality along the railroad that can handle it, the volume [crude oil] is too greatWe just have to hope that nothing happens, honestly.” 
  • The Pottstown Mercury 3-1-15 editorial got it right concluding, “Clearly, hope is not enough to maintain safety…”
  • No matter what claims the oil, rail, or nuclear industries make, there is no emergency plan that could effectively deal with a disaster of this magnitude within 1/8 of a mile of Limerick’s fuel pools.

Fire fighters and emergency responders shouldn’t be expected to be on the front lines of such devastating uncontrollable disasters.

  • Emergency responders are smart to be concerned.
  • Authorities say most fire and emergency departments are only capable of responding to a 9,000 gallon tanker truck incident, but DOT-111 crude oil cars hold 30,000 gallons, exceeding the response capacity.

Catastrophic disasters from crude oil explosions/fires near Limerick Nuclear Plant can and must be prevented with foresight and political will to face this unnecessary risk and take action.



  • Limerick has a history of chronic shutdown problems.  Publically available official reports show that Limerick’s reactors may not be able to be shut down safely in an emergency.
  • An explosion and days-long fire from a crude oil “bomb train” derailment could require immediate Limerick reactor shutdowns to avoid meltdowns.  This may not be possible.


  • Entire towns have been forced to evacuate after a bomb train disaster.  Limerick workers, including guards, so close to the disaster should certainly be evacuated for their own health and safety.  Yet, evacuation of Limerick workers could increase meltdown risks in Limerick’s 2 reactors and 2 fuel pools.
  • Limerick workers might be unable to access all necessary emergency equipment vital to preventing meltdowns, due to a crude oil explosion, massive heat, and extended days of thick black smoke.
  • Limerick’s control room would likely be impacted from days of thick black smoke.  Even Occidental Chemical’s vinyl chloride powder accidents (.7 of a mile from Limerick Nuclear Plant) caused Limerick’s operators to “button up” Limerick’s control room.   What would happen in days of thick black soot from a huge crude oil fire?
  • Extreme heat and soot could disturb the natural air flow needed for casks holding high-level radioactive wastes.  Blocked cask vents could go undetected in thick black smoke leading to overheating of the stored high-level radioactive wastes.


  • NRC weakened Limerick’s fire safety regulations, and still fails to enforce the weakened regulations.
  • Limerick does not use the safest fire barrier systems in all areas, to protect cables important to safe shutdown.  Even Limerick’s recent 4-5-15 fire in a reactor panel shows that Limerick is extremely vulnerable to fire that could lead to meltdowns.
  • Reduced fire safety at Limerick has new meaning in relation to days-long crude oil fires because Limerick’s fire barriers are only required to protect cables for 1 hour.
  • Without the safest fire barriers, fire detection and suppression systems, and spatial separations, Limerick plant stability is compromised. Fires can erupt in many ways at a nuclear plant.  Fires from crude oil bomb trains add significantly to Limerick’s risk of meltdowns due to fire.
  • Reactors and fuel pools need a constant supply of water to prevent meltdowns.  A crude oil fire could disable Limerick’s cooling water delivery system, resulting in simultaneous meltdowns in Limerick’s 2 reactors and 2 fuel pools.
  • Exelon’s liability limit encourages cutting corners to save money.


  • Evacuation of security guards could increase risk of a terrorist attack.
  • Terrorists could trigger a bomb train derailment,  initiating crude oil explosions and fires at any point along the lengthy rail track route on the nuclear plant site.





ACE’s evaluation of  Exelon’s fatally flawed 2012 “Evacuation Time Estimate (ETE) For Limerick’s Plume Exposure Pathway” is useless as a planning tool for safe evacuation

  • Exelon’s ETE is self-serving fiction riddled with inconsistencies and inaccuracies, fact-free spin, unsubstantiated suppositions and assumptions, illogical conclusions.
  • Exelon’s ETE is not realistic and must be rejected.

To understand why Limerick Nuclear Plant’s emergency and evacuation plans are fatally flawed and inadequate, we urge you to review the 8-part ACE video-blog series on Emergency and Evacuation Plans for Limerick at   It serves as a wake-up call to millions in the Greater Philadelphia Region about Limerick Nuclear Plant’s negligent emergency and evacuation planning:

In 1980 NRC publicly admitted that safe evacuation from Limerick was impossible.  NRC testified at Limerick’s 1980 public hearing that Limerick had double the population density for a safe evacuation.  NRC admitted that people within 30 miles would be harmed.  Things are far worse now, since the population around Limerick has increased dramatically in the past 35 years.

Thomas Sullivan, Montgomery County Director of Public Safety, testified at a public hearing for Limerick Nuclear Plant relicensing in 2011 that many local, county, and state roads used for evacuation that feed the local highways were no longer suitable for the amount of traffic that Limerick’s EPZ evacuation could produce.  Traffic conditions have worsened, yet in 2015 Thomas Sullivan, claimed, “Because of the Limerick generating plant, we have robust plans…” (Mercury 2-23-15), dismissing potential dangers associated with the transport of crude oil.  The serious problems and flaws with Limerick’s Emergency and Evacuation plans have been ignored by Mr. Sullivan and others.


Not Surprising! NRC Killed Its Cancer Study



© 2015 The Mercury (

NRC Fails To Protect Public From Nuclear Plants

NRC killed its study on cancer in populations near nuclear plants (The Mercury AP article Sept. 10).

Not surprising! The impossibility of hiding the undeniable truth about increased cancer around nuclear plants is the real reason NRC killed its study.

Many studies already documented cancer increases around nuclear plants in Europe and the U.S., including around Limerick Nuclear Plant.

NRC has powerful self-serving reasons not to disclose the damning reality. NRC lies about nuclear plant radiation and our cancer risks to protect the nuclear industry and their own jobs. Admitting the truth would trigger a public outcry, forcing Limerick and other nuclear plants to close. NRC officials would lose their jobs, with nothing left to regulate.

NRC wasted $1.5 million and over five years developing strategies to disguise the truth. Despite initial independent efforts to stop NRC from distorting reality, its cancer study methodology remained fatally flawed. See:

NRC intentionally designed this whitewash to support NRC’s unsubstantiated, industry-biased, absurd position that radiation releases from nuclear plants aren’t harmful.

NRC officials should be ashamed:

1. NRC first falsely claimed no radiation escapes

2. Next, NRC admitted radiation is released, but made unsubstantiated claims that it’s not harmful

3. Now, NRC is shockingly considering an industry inspired scheme to claim, “a little radiation is       good for you.”

Why? To eliminate liability and minimize industry costs associated with radiation harms, evacuation planning and decommissioning.

John Gofman, a medical physicist, warned over 40 years ago that nuclear power kills. He said, “The evidence on radiation producing cancer is beyond doubt. It is not a question anymore: radiation produces cancer, and the evidence is good all the way down to the lowest doses.”

Physicians For Social Responsibility and The National Academy of Sciences report stated there is no safe level of radiation exposure. Continuous low dose radiation exposure is just as harmful as one high-level dose. See – Section #3 Radiation – No Safe Dose.

We never believed NRC would release a study showing nuclear power’s true harmful health impacts.

For years, NRC ignored documented shocking cancer rates, especially in children, around Limerick Nuclear Plant. ACE repeatedly informed NRC, yet Limerick wasn’t one of six nuclear plants included in NRC’s cancer study. Written comments on NRC’s cancer study were also submitted by ACE on May, 18, 2012 and during a national cancer study phone meeting on Dec. 11, 2013.

Since 2000, ACE investigated the link between Limerick Nuclear Plant’s radioactive releases and our shocking skyrocketing cancer increases, far above the national average. (Pa. Cancer Registry and CDC data 1985 to early 2000s). Links are clear. Childhood cancer rates near Limerick spiked to 92.5 percent higher than the national average by 1999. RPHP’s tooth study showed high levels of Strontium-90 radiation in our baby’s teeth. SR-90, not found in nature, was released from Limerick into our environment since 1985. ( Section#2, Cancer – Skyrocketing Increases: Links to Limerick)

Limerick’s radioactive releases end up in our drinking water, soil, food and people. Most impacted: fetuses and children. Additive, cumulative and synergistic impacts were never accurately determined. NRC has no accurate idea how much radiation Limerick released over the past 30 years, nor actual resulting health harms. ( Section#1, Radiation – Limerick’s Routine Releases)

NRC does no radiation monitoring, yet absurdly claims releases are small. Exelon, with a vested interest in the outcome, controls all radiation testing and reporting. Deception includes:

• Over 100 radionuclides are released, yet not continuously monitored and reported in real time.

• Radiation spikes are hidden using averages, estimates.

• Examples: Limerick’s unreliable radiation monitoring. Up to 36 percent margins of error (radioactive gases) make reports unreliable. Radiation monitor for a vital drinking water resource was inoperable for over a year. Limerick violates Safe Drinking Water Standards with impunity, sometimes drastically.

Radiation releases will increase with use of high-burn fuel and aging. If you want Limerick closed to protect you and your family, e-mail

Time To End Taxpayer Funding Of NRC

Time to End Taxpayer Funding of NRC

How much is your life worth? Not much, according to the NRC.

Why? Because NRC reduces the incalculable worth of a human life to a low-balled monetary amount on paper that compares human lives to the costs of installing the most effective, protective safety systems and equipment available at Limerick Nuclear Plant.

From all the evidence we’ve seen, it’s apparent that NRC’s aim is not to protect the public, but to protect nuclear industry profits.  NRC provides nothing more than an illusion of safety. NRC’s assurances that Limerick Nuclear Plant is safe are as stale as old cigarette ads.

NRC’s budget for 2016, which has been submitted to Congress, shows that $122 million (about 10%) comes from the taxpaying public. The bulk of NRC’s budget (about 90%) comes from the nuclear industry that NRC is supposed to regulate.  This creates an undeniable conflict of interest.

The problem is that NRC continually weakens its regulations to benefit Exelon, despite Limerick’s obvious increasing risks to public health and safety.  Exelon requests that regulations be changed or eliminated and NRC always complies.  Regulations at Limerick have been drastically weakened through exemptions, exclusions, amendments, deferments, delays, relief from inspections, and experiments.

In essence, NRC’s weakening of Limerick’s regulations is a service NRC provides which allows Exelon to cut corners and avoid costs.  NRC should never have allowed Exelon to substitute a list of plans and commitments instead of the testing of Limerick’s aging equipment and systems to prove that they work, as required for Limerick relicensing.

When citizens want to express objections to NRC’s reckless decisions and actions, NRC offers the public NRC’s dead-end petition process, a total farce.  NRC has never ruled in favor of any petition filed against Limerick. Just over the past four years, for example, NRC dismissed the following petitions, in spite of the valid issues they raised:

  • A petition from the National Resources Defense Council (NRDC) requesting an updated Severe Accident Mitigations Alternatives (SAMA) for Limerick
  • Petitions from several nuclear engineers warning that Limerick’s reactors may fail.

On May 21, 2015, NRC held its annual open house stating that NRC would respond to public questions about Limerick’s 2014 performance. NRC discouraged public participation by:

  • Giving short notice in the local paper (the same day that the meeting was scheduled)
  • Holding the meeting the day before a long holiday weekend
  • Holding the meeting from 5:00 p.m – 6:30 p.m., inconveniently dinner time for most families

Despite the fact that NRC’s open house was about NRC’s assessment of Limerick’s 2014 operations, No  NRC resident inspector who worked at Limerick in 2014 was in attendance. Instead, new 2015 resident inspectors were there, but they said they knew nothing about Limerick’s 2014 inspections and appeared to be woefully ignorant of Limerick’s inherent defects.   This repeated tactic allows NRC to avoid accountability to the public.

Of utmost concern is NRC’s irresponsible refusal to test the surveillance capsules from Limerick’s defective reactors for embrittlement.  At the open house, NRC officials absurdly defended NRC’s previously stated decision to test another nuclear plant’s reactor surveillance capsules to determine Limerick’s reactor embrittlement status and associated risk to the public. Limerick’s reactors have been operating for 30 years. Would you have confidence that your 30 year-old car is safe to drive based on the inspection of someone else’s car?

NRC’s conflict of interest results in unprotective decisions about Limerick that can lead to meltdowns and widespread devastation in which the public would lose everything.  NRC should value public safety over Exelon’s profits, but its actions show that NRC doesn’t care about public safety.

Maybe it’s time to end public taxpayer funding of NRC and ask Congress to reject NRC’s budget proposal of $122 million of taxpayer money.

Limerick Nuclear Plant Is Not Protected Against Tornado/Wind Hazards

Limerick Nuclear Plant Is Not Protected Against  Tornado/Wind  Hazards

Heads should roll at NRC.  NRC is allowing Exelon to delay and even avoid costs for minimizing Limerick Nuclear Plant meltdown risks, despite the fact that the Greater Philadelphia Region could become a dead zone for generations and millions of us could lose everything if Limerick melts down.

NRC is negligently allowing Exelon to use stall tactics to avoid finalizing procedures to insure all Limerick’s emergency equipment can remain deployable after a tornado to minimize risk of meltdowns.  No strategies exist for deployment path debris removal at Limerick.  This is unacceptable.

NRC’s own 3-17-15 Audit Report states that Limerick’s equipment storage configuration is NOT considered to be reasonably protected against “tornado wind/missile hazards” and that Exelon still has “NO PLAN” completed for compliance.

To allow Exelon to get away with not immediately insuring Limerick’s access or use of necessary emergency equipment in a tornado wind/missile hazard is regulatory malpractice by NRC. Tornadoes occur in our region.  Risks are increasing.  Just within three weeks in 2015 (late June to early July),  three tornadoes occurred in our area.  Tornado watches and warnings have become frequent.

Examples include:

  • 7-10-15:  The National Weather Service confirmed that three tornadoes touched down in PA, including one that ripped off the roof of an elementary school in Berks County.
  • 7-1-15:  The National Weather Service confirmed an EF-1 Tornado touched down in Honey Brook, Chester County.
  • 4-20-15: A Tornado watch was in effect for Montgomeryand Chester Counties.
  • 7-27-94: A DEADLY TORNADO STRUCK PARTS OF LIMERICK TOWNSHIP (Near Limerick Nuclear Plant), killing an infant and her parents and destroying property.
  • It was reported that a tornado blew off the roof of the NRC building in King of Prussia.

FEMA’s website states that citizens should pledge to prepare for tornadoes, calling them nature’s most violent storms.   So why isn’t FEMA telling NRC to require Exelon to immediately prepare the Limerick site against tornado/wind hazards?   Tornadoes can develop so rapidly that there can be little, if any, warning.   FEMA states that a tornado damage path can be in excess of one mile wide and 50 miles long.  That could encompass most of Limerick Nuclear Plant’s 600 acre site.  FEMA says a tornado can cause fatalities and devastate a neighborhood in seconds.  Devastation could be catastrophic if a tornado triggers meltdowns at Limerick.

Four years after Fukushima meltdowns (March 2011), Limerick’s meltdown threats have increased dramatically, yet NRC has failed to require Exelon to complete any of NRC’s March 2012 Post-Fukushima orders to avoid meltdowns.  Examples:

  • No filtered vents to minimize radioactive fallout
  • No fuel pool instrumentation to immediately identify loss of vital cooling water
  • No way identified to minimize and/or eliminate growing risks for earthquake-triggered meltdowns Examples of Limerick’s unprecedented risks from earthquakes include:

Limerick’s reactors, fuel pools, rad-waste building, turbine building, and control room are all built directly on top of earthquake fault fractures

Four other earthquake faults within 17 miles of Limerick

Massive fracking in PA and surrounding states can trigger earthquakes.  This dramatically increased Limerick’s risk for meltdowns, especially from disruption in any of the miles of vital pipes and cables under Limerick needed to transport water and power to prevent meltdowns.

Given such extraordinary risks to the public’s health, safety, and financial interests, NRC should require Exelon to take immediate action to insure that all Limerick Nuclear Plant’s emergency equipment remains deployable during a tornado/wind hazard event and require Exelon to comply with all NRC’s 2012 Post-Fukushima recommendations to prevent meltdowns.

Every local, state, and federal official in the Greater Philadelphia Region should pressure NRC to require Exelon to take all immediate precautions to prevent meltdowns.   If you agree, contact ACE at  For more information on details about Limerick’s threats to our region, visit

NRC’s Reckless Disregard For Health And Safety Is Shameful

NRC’S Reckless Disregard For Health And Safety Is Shameful

“Safety is NOT a primary concern of NRC”.   If NRC’s primary concern was safety, NRC would be closing Limerick Nuclear Plant as soon as possible.

NRC has in fact shown reckless disregard for the consequences of Limerick Nuclear Plant operations on the people in the Greater Philadelphia Region.

Despite ACE’s repeatedly expressed public concerns on a broad range of unprecedented health and safety issues related to Limerick, NRC’s responses have shown that NRC REALLY DOESN’T CARE ABOUT HEALTH AND SAFETY.

NRC’s reckless disregard is identified by inaction related to Limerick’s threats and harms below:

  1. More Radiation Releases from Limerick Using High-Burn Fuel
  2. Radioactive Contamination of Vital Drinking Water Resources
  3. Depletion And Pollution of Drinking Water for Almost 2 Million People From Pottstown To Philadelphia
  4. Massive PM10 Air Pollution (More Deadly Than Ozone) from Limerick’s Cooling Towers
  5. Faster Corrosion Of Equipment and Systems Than Estimated
  6. Unprecedented Earthquake Risk Could Result in Fukushima-Like Multiple Meltdowns
  7. Tons of Deadly High-Level Radioactive Wastes Piling Up On-Site, In Our Back Yard, with No Long-Term Safe Solution
  8. More Dangerous High-Level Radioactive Waste Storage and Transport from Using High Burn Fuel
  9. Limerick is Less Safe Four Years After Fukushima.  NRC Failed to Require Exelon Comply With NRC’s Post Fukushima Recommendations To Minimize Meltdown Risks.
  10. Inadequate Safeguards Against Terrorists Air Strikes, Missiles, Drones, and Cyber Attack Threats
  11. Derailment and/or Explosions from Crude Oil Bomb Trains Traveling Through the Limerick Site

Costs to Exelon always trump public safety in NRC decisions. Exelon is making a mockery of NRC’s 2012 Post-Fukushima Orders to prevent meltdowns.

NRC is allowing Exelon to delay costs of compliance (for up to 7 years, maybe longer). That seriously jeopardizes the health and financial interests of millions of people in the Greater Philadelphia Region because NRC’s 2012 recommendations were about mitigating meltdown risks at Limerick.

Meltdown threats are increasing dramatically at Limerick from massive fracking that can trigger earthquakes, to tornado wind/missile hazards, and cyber and drone attacks.  Yet, Limerick’s Fukushima-like reactors are no safer now than before the Fukushima meltdowns in 2011:

  • Despite increasing risks for Limerick meltdowns, NRC allowed Exelon to avoid costs for radiation filters. In 2012, NRC’s own staff said these filters were imperative, regardless of cost to industry, because the vents installed to minimize explosions would become “radioactive fire hoses into the sky”.  Three years after NRC’s 2012 orders, Exelon still doesn’t even have plans completed for vents.
  • Despite increasing risk of earthquakes from fracking, and the unprecedented risk of meltdowns from Limerick’s reactors and fuel pools built with substandard cement directly over fault fractures, NRC is ignoring risks.  Four other earthquake faults are within 17 miles of Limerick.  Even the 8-23-11 Virginia earthquake jolted Limerick. Miles of Limerick’s underground pipes and cables vital to preventing meltdowns can be disrupted, yet are not actually inspected.  Often, NRC allows Limerick’s monitoring systems to remain inoperable for long periods of time, even over a year sometimes. NRC’s solution to Limerick’s unprecedented earthquake risks: Allow Exelon until 2019 to complete a “self-serving seismic study”.  Hardly risk reduction!
  • Despite increasing tornado risks, even in our region, NRC admitted in its 3-17-15 audit report that Limerick is not reasonably protected against the tornado wind/missile hazard.  Equipment needed to mitigate a tornado would not be available.

NRC’s PR people appear to be either uninformed or ethically challenged. NRC would close Limerick if they really care about our safety.  For more information see or e-mail

Rebuttal of NRC’s Op-Ed Claiming That Public Safety is its Priority

REBUTTAL of NRC’s Op-Ed Claiming that Public Safety is its Priority

NRC’s recent Mercury op-ed (4-19-15) is an outrageous deception. NRC is many things but it is not always truthful and it is not always humane. NRC’s decisions for Limerick have shown reckless disregard for public health and safety, despite NRC’s assertion that safety is its priority. NRC clearly puts Exelon’s profits before safety.

The sad reality is that for NRC, it’s all about allowing dangerous degrading nuclear plants like Limerick to continue operating, despite the risks and costs to all of us.

Things are so bad at Limerick that NRC is actually stonewalling the public.  Honest, direct answers are hard to come by.  After many e-mail exchanges with the NRC regional chief for Limerick, ACE tells us that it is still unable to get direct answers about dangerous situations and safety-related breakdowns in Limerick’s systems and equipment.  NRC’s chief went so far as to inform ACE that he doesn’t even want the public to e-mail NRC’s on-site resident inspectors with Limerick-specific concerns. Why does this NRC chief expect the public to contact only him when he appears to be a PR person with the goal of controlling Limerick information on behalf of Exelon’s interests, not public safety?  ACE found that Limerick’s on-site inspectors can provide more accurate and timely responses to serious concerns than anyone in the regional office.

NRC has NOT enforced its regulations at Limerick, which NRC’s op-ed stated that it has the authority to do.  Instead of  enforcing compliance, when rules or licensed conditions for Limerick are violated, NRC has weakened or eliminated its regulations, saving Exelon the costs of compliance.  We should all object to weakened safety at Limerick through NRC’s granting of exemptions, exclusions, experiments, amendments, dangerous delays, and reliefs (counting relief from inspections as compliance).  These tactics greatly jeopardize the health and financial interests of everyone in the Greater Philadelphia Region.

Limerick’s records show that its reactors were defective from the start and now, 30 years later, they are degrading faster than estimates predicted.  Our most recent concern is about the high number of Limerick scrams (planned or unplanned shutdowns), that can cause age-degraded defective reactors like Limerick’s to crack, leaking radioactive water from the core, which can lead to meltdowns. Testing on Belgium’s reactors confirmed our concerns about cracking: 16,000 cracks were identified in two reactors. Limerick’s reactors could have even more cracks.   A nuclear engineer filed a petition against Limerick due to Limerick’s high number of scrams and their impact on reactor embrittlement-induced cracking:

  • ACE identified 12 scrams in NRC’s own safety reports, just from February 25, 2011 to February 23, 2015.
  • On February 23, 2015 Limerick’s Unit 1 scram was due to a valve problem. TMI’s partial meltdown was caused by a valve problem.
  • On April 13, 2015, Unit 2 suffered back-to-back scramming events, which we haven’t seen before  (an unsuccessful planned scram followed by a manual scram).

Don’t let NRC tell you that Limerick is safe.  NRC’s conclusions about the safety of Limerick are dependent entirely on Exelon’s self-serving guesstimates and reports.  Exelon is making a mockery of NRC’s regulatory process as NRC ignores:

  • Unprecedented earthquake risks that increase Limerick’s meltdown risks
  • PA fracking that increases Limerick’s earthquake risks
  • Crude-oil “bomb train” tracks going through the Limerick site.  A derailment could trigger a Limerick catastrophe.
  • Cyber attacks and other terrorist threats that are increasing.

Don’t believe baseless NRC assurances that Limerick is safe.  The only way to minimize risks of meltdowns is to close Limerick.  If you agree, e-mail ACE at  For more information see

Crude-Oil Bomb Trains Travel Through Nuclear Plant Property

Crude-Oil Bomb Trains Travel Through Limerick Nuclear Plant Property

The Mercury (


Saturday, April 25, 2015

The Mercury article of Feb. 23, “We just have to hope that nothing happens” has profound implications to everyone in the Greater Philadelphia Region. We applaud the March 1 Mercury editorial conclusion, “Clearly, hope is not enough to maintain safety…”

So-called “bomb trains” containing up to 3 million gallons of explosive, flammable, hazardous crude oil travel right through Pottstown and the Limerick Nuclear Plant Site. A derailment, explosion and days-long fire ball near Limerick’s reactors and deadly fuel pools could trigger simultaneous meltdowns with catastrophic radioactive releases. Millions of Greater Philadelphia Region residents could lose everything forever.

Days of thick black smoke from a crude oil fire could be devastating. Even Occidental Chemical’s large vinyl chloride accidents (seven-tenths of a mile from Limerick) caused problems at Limerick, according to employees, some of whom are very worried about crude oil train derailments.

Risks are increasing. Emergency responders are smart to be concerned. They shouldn’t be expected to be on the front lines of such devastating uncontrollable disasters.

Train derailment disasters should be anticipated. Sixty-five tank cars bound for Philadelphia had loose, leaking, or missing safety components to prevent flammable, hazardous contents from escaping (Hazmat report – last two years). A fuel-oil train already derailed a few miles from Philadelphia.

Heat from the rupture and ignition of one 30,000-gallon car can set off a chain reaction, causing other cars to explode, releasing a days-long fireball. Basically, responders must let it burn out.

Over 100 railcars, estimated to hold three million gallons, regularly sit on tracks from the Dollar General in Stowe to Montgomery County Community College.

ProPublica data from the federal Pipeline and Hazardous Materials Safety Administration (2011-2014) shows incidents in over 250 municipalities. The worst of eight major crude oil train accidents include:

• A train derailment and explosion killed 47 and destroyed 30 buildings in Quebec.

• 2,300 residents were evacuated in North Dakota. The fireball was observed states away.

Safer trains aren’t the answer. A new safer-design derailed February 2015 in West Virginia, despite adhering to the speed limit. Hundreds of families had to flee their homes in frigid weather. Burning continued for days. Drinking water and electricity were lost. Leaking crude oil poisoned the water supply. Fireballs erupted from crumbled tank cars, underscoring volatility of crude oil’s propane, butane, etc.

Safe evacuation from our densely populated region is an illusion. Limerick Nuclear Plant’s evacuation plan is unworkable and unrealistic, not robust as claimed by a health official. Just consider work hour traffic combined with deteriorated roads and bridges. We encourage officials to visit to view ACE’s 2012 video-blog series on the reality of Limerick’s evacuation plan. For a graphic presentation call (610) 326-2387.

Who pays to deal with irreversible devastation from train derailments and meltdowns? Clearly, not the oil industry, nuclear industry, railroad or government. We’d be on our own, despite:

1. Long-term ecological damage that would leave ghost towns that can’t be cleaned up safely.

2. Risking the vital drinking water resource for almost two million people (Pottstown to Philadelphia).

3. Millions of people losing their homes, businesses and health.

Richard Lengel, Pottstown’s Fire Chief, admitted, “If something catastrophic happens, there’s no municipality along the railroad that can handle it, the volume [crude oil] is too great. We just have to hope that nothing happens, honestly.”

Hope is no solution! Neither is denying the reality of our unacceptable devastating risks.

The catastrophic disasters we face can, and must, be prevented with foresight and political will to face the facts and take action. Enough of corporate profits jeopardizing public safety.

Wake up! Speak up! Tell local, state and federal elected officials to stop this insanity!

Say no to dangerous crude oil trains traveling through our communities and the Limerick site.

Say no to continued Limerick Nuclear Plant operations to avoid meltdowns that can be triggered by cyber/terrorist attacks, embrittled/cracking reactors, earthquakes and now oil-train explosions/fires.

Relicensing Limerick Nuke Plant Ignores Safety Risks

Tuesday, January 27, 2015

It’s insanity for the Nuclear Regulatory Commission to allow Exelon’s Limerick Generating Station to operate a total of 60 years, yet that’s the result of NRC’s reckless rubberstamp relicensing. To relicense Limerick, NRC negligently weakened its regulations reducing public protections and long term plant stability.

NRC rigged the game and dangerously tilted the playing field. NRC makes the rules, breaks them, then weakens and remakes them to let Exelon slide to save money, despite potentially devastating consequences to millions of people in the Greater Philadelphia Region. This constitutes regulatory malpractice. We need and deserve a Congressional investigation on NRC’s negligent relicensing of Limerick.

Though Limerick is a radioactive time bomb, NRC allowed dangerous loopholes, exemptions, delayed actions, and license amendments. NRC irrationally allowed Limerick to operate another 30 years, despite Limerick’s profound vulnerability to accelerated corrosion and age-related deterioration of its systems and equipment. For decades taxpayers and ratepayers subsidized this fault-riddled nuclear plant, with its defective reactors and substandard construction, none of which can be fixed.

Limerick cannot be completely protected from a cyber or other terrorist attack that can cause Limerick to spew enough radiation into our air to cause us to lose everything. Yet, Exelon, profiting from this insane gamble, is almost entirely shielded from liability for the public’s health and financial losses resulting from Limerick meltdowns.

Instead of protecting our health, safety, and the environment, NRC denies reality to defend this dangerous, dirty, risky, deteriorating, corroding nuclear plant. For another 30 years we will have no real protection from:

• Radioactive poisoning of our air and water

• Massive dangerous PM-10 air pollution from the cooling towers

• Schuylkill River depletion

• Pumping toxic mine water into the river for Limerick operations

• Producing deadly radioactive wastes for which there is no safe solution

• Meltdown threats from cyber, air, and missile attacks by terrorists

• Earthquake fault fractures under Limerick’s reactors and fuel pools

The good news is, like Vermont Yankee Nuclear Plant, Limerick can still be closed now. Even though relicensed, Vermont Yankee was closed December 29, 2014. Vermont elected officials and dedicated activists worked together to get Vermont Yankee closed in order to protect public health, safety and the environment. Now, one less nuclear reactor threatens the U.S. with a Fukushima-like catastrophe.

If Exelon was compelled to comply with original NRC safety regulations, we believe Exelon may have closed Limerick due to costs required for meeting original NRC safer standards. In 2013, high equipment repair costs apparently led to the shutdown of two San Onofre reactors.

NRC’s middle management went to extraordinary lengths to nullify NRC staff’s own post-Fukushima safety recommendations and safety upgrades recommended for Limerick relicensing.

Our elected officials need to look at reality and stand up now to protect their constituents. Despite years of repeated ACE efforts to inform elected officials of Limerick’s unprecedented threats and harms, to date, our officials have chosen to ignore reality. We believe the lure of political contributions effectively silenced opposition to Limerick, despite undeniable unprecedented threats to the future of millions of people.

Silence protects Exelon profits, but allows us to continue to be victimized by Limerick Nuclear Plant operations. Our elected officials need commitment and courage to protect us like officials in Vermont and California, who had the political will to help close their nuclear plants.

Limerick must be closed now to minimize health threats, harms to the environment, and to prevent an avoidable catastrophe that would be devastating to all who live and work in the Greater Philadelphia Region and beyond.

We need our local, state, and federal PA officials to help close Limerick now. They need to hear from you. Ask them to review evidence compiled at or call (610) 326-2387 for a presentation.

In reality, Limerick’s electric can be replaced now with cleaner, safer, and cheaper electric that won’t threaten our health and lead to a catastrophe.
