Peach Bottom

 By letter to the Nuclear Regulatory Commission (NRC) dated November 19, 2009 (Agencywide 

Documents Access and Management System (ADAMS) Accession No. ML093290053), GE 

Hitachi Nuclear Energy (GEH), requested that the NRC remove, from ADAMS, documents 


NRC memo:

    Nuclear Regulatory Commission officials in King of Prussia, Pa., have selected Adam Ziedonis as the new resident inspector at the Peach Bottom Atomic Power Station in Delta, Pa. 

    He joins NRC Senior Resident Inspector Fred Bower at the two-unit site, which is operated by Exelon Nuclear. 






 The U.S. Nuclear Regulatory Commission (the Commission) is considering the issuance 

of an order under Title 10 of the CODE OF FEDERAL REGULATIONS (10 CFR), Section 50.80 

approving the indirect transfer of the Facility Operating License DPR-12 for Peach Bottom 



Below is a chronology of news and other security and safety events that have taken place at the Peach Bottom Atomic Power Plant in York County, Pennsylvania, on the Susquehanna River, since 2005. This is not a final list and content maybe added, so check for updates. 


Peach Bottom:


May 13, 2011 – The NRC said there would be no significant environmental impact with the transfer of low-level radioactive waste from the Limerick Generating Station in southeastern Pennsylvania to a storage facility at the Peach Bottom plant.


Peach Bottom officials initially requested a license amendment to allow the transfer of the waste on Jan. 6, 2010. The waste does not include any transfer of spent nuclear fuel from Limerick.


Exelon operates both nuclear power plants.


The Limerick plant does not have the capacity to store all of the low-level radioactive waste it generates. The NRC noted that the Barnwell disposal facility in South Carolina is no longer available for Limerick, but Peach Bottom has the ability to store a large amount of low-level waste on an interim basis.


In its environmental analysis, the NRC noted that there would be two or three shipments a year from Limerick to Peach Bottom. “The distance between the plant sites is less than the distance that was previously traveled to the Barnwell disposal facility in South Carolina,” the NRC noted.


“The staff concludes that the radiological impacts associated with the transportation, handling and storage of low-level radioactive waste at Peach Bottom will not result in a significant impact to plant workers and members of the public,” the NRC said.


“The proposed action will not significantly increase the probability or consequences of accidents. No changes are being made in the types of effluents that may be released offsite. There is no significant increase in the amount of any effluent released offsite. There is no significant increase in occupational or public radiation exposure. Therefore, there are no significant radiological environmental impacts associated with the proposed action.”



Berwick plant


May 16, 2001 – Operators of the Susquehanna nuclear plant near Berwick shut down the Unit 1 reactor for an inspection of the main turbine.


The precautionary shutdown was done to inspect the blades of the turbine. Workers detected defects on similar blades in the Unit 2 turbine during a routine inspection as part of a refueling and maintenance outage.


Officials said the defective turbine blades on Unit 2 are being replaced. Unit 1 will be returned to service when the inspection and any needed repairs are completed, PPL officials said.




May 13, 2011 – In the aftermath of the problems at the Japanese Fukushima Daiichi Nuclear Station resulting from the earthquake and tsunami, the NRC asked various nuclear plants in the U.S. to assess their capabilities to respond to extraordinary consequences. The plants were asked to evaluate measures to address their ability to mitigate problems from large fires or explosions; station electrical blackouts; internal and external flooding; and the impact from seismic events.


The NRC found both Peach Bottom and Berwick were in good shape for any of the listed catastrophic events.


At the Peach Bottom facility, no deficiencies were found addressing blackout conditions. On flooding events, the NRC noted that the licensee identified several minor barrier and door discrepancies, and procedural enhancements were entered into its corrective action program.


On the other issues, the NRC inspector noted that equipment was available and functional, and no significant deficiencies were identified. However, the licensee identified several enhancements needed to improve the long-term reliability of equipment and several enhancements needed to increase the survivability of portable equipment.


At Berwick, plant operator PPL identified a vulnerability in a blackout because a portable diesel generator may be unavailable for use because it is not routinely stored in a hardened building or enclosure. This problem was entered into the plant’s corrective action program. The NRC also observed that no concerns were identified from flooding events, although some issues were entered into a corrective action program.


On the other issues, certain vulnerabilities were identified in case of a major seismic event, and corrective actions are planned.
