NRC Approves Power Uprate For Peach Bottom Atomic Power Station

The Nuclear Regulatory Commission has approved a request by Exelon Generation Co. to increase the generating capacity of Peach Bottom Atomic Power Station, Units 2 and 3, by 12.4 percent each.

The NRC staff determined Exelon could safely increase the reactors’ output primarily by upgrading certain plant systems and components. NRC staff also reviewed Exelon’s evaluations showing the plant’s design can handle the increased power level.

The NRC’s safety evaluation of the plant’s proposed power uprate focused on several areas, such as the nuclear steam supply systems, instrumentation and control systems, electrical systems, accident evaluations, radiological consequences, operations and training, testing, and technical specification changes. For added confidence in the analysis, the NRC staff also conducted independent confirmatory calculations and audits of selected areas.

The power uprate authorizes Peach Bottom, located approximately 18 miles south of Lancaster, Pa., to increase each boiling water reactor’s generating capacity by approximately 140 megawatts electric. Exelon plans to implement Unit 2’s uprate during the fall 2014 refueling outage and Unit 3’s uprate during the fall 2015 refueling outage.

The NRC published a notice about the power uprate application in the Federal Register on April 9, 2013. The agency’s evaluation of the Peach Bottom uprate will be available through the NRC’s ADAMS electronic document database by entering Accession Number ML14133A046.

Event Text

"At 13:00 [EDT] on Saturday, August 23, 2014, both trains of the Peach Bottom Atomic Power Station (PBAPS) Emergency Service Water (ESW) System were declared inoperable on Unit 2 and Unit 3, due to a pin-hole, through wall piping leak. In accordance with 10CFR 50.72(b)(3)(v), this event is being reported as an event or condition that could have prevented the fulfillment of the safety function of systems that are needed to shut down the reactor and maintain it in a safe shutdown condition, remove residual heat and mitigate the consequences of an accident. 

"At 19:22 [EDT], the station received verbal approval of a Notice of Enforcement Discretion (NOED) request. Simultaneously, the station is preparing an evaluation to support an emergent-relief request.

Anti-nukers, congressmen fret over Entergy finances, requested subsidies


Recorder Staff
Monday, August 25, 2014
(Published in print: Tuesday, August 26, 2014)

The Nuclear Regulatory Commission recently reopened a year-old petition from anti-nuclear groups concerned about Entergy Corp.’s financial ability to safely operate its nuclear plants, including Vermont Yankee.

The original petition, filed before Entergy announced plans to shut the 620-megawatt Vernon, Vt., reactor at the end of 2014 for economic reasons, had called for NRC staff to seek detailed financial information from Entergy Corp., but after the company balked, arguing such scrutiny was beyond NRC’s purview, the commissioners backed down.

After a letter last November from Congressmen Edward Markey, D-Mass., and Bernie Sanders of Vermont to the NRC the agency has again sought financial information from Entergy.

The congressmen said “financial distress and the failure to maintain sufficient operating funds would be expected to signal the potential for future degradations in safety brought about by a licensee’s need to conserve funding.”

Meanwhile, Entergy last month reported a 55 percent decline in second-quarter earnings compared to the corresponding period last year, forcing it to eliminate 800 jobs nationwide.
