FENOC responds to NRC on Davis-Besse reports

FirstEnergy Nuclear Operating Company (FENOC) yesterday filed with the Nuclear Regulatory Commission (NRC) a response to the commission’s Demand for Information (DFI) issued May 14, 2007. The demand is related to recent reports prepared for arbitration of an insurance claim for replacing the damaged reactor head at the company’s Davis-Besse plant in 2002. The response is expected to be available through the NRC Web site, www.nrc.gov, later today.

In its response, FENOC reaffirms that it accepts full responsibility for the mistakes and omissions leading up to the damage to the reactor vessel head and that the company maintains its strong commitment to operate Davis-Besse and its other nuclear plants safely and responsibly. FENOC also reaffirms the validity of its own analysis of the event’s root causes and corrective actions, which was confirmed through a detailed review. Additionally, this review reinforces that no further steps are necessary to assure plant safety at Davis-Besse and similar plants. The company’s response also addressed three specific areas requested by the NRC:

After closely reviewing a report by Exponent Failure Analysis Associates examining the reactor head damage, FENOC continues to believe that if it would have properly implemented the boric acid corrosion control program, leaks from control rod drive nozzles would have been visible in 2000 or before. Accordingly, FENOC continues to support the validity of its own root cause analysis. Furthermore, the company believes its root cause analysis is a comprehensive and correct source on which to base corrective actions preventing the recurrence of such events.

Regarding a separate insurance arbitration-related report prepared by Roger J. Mattson, Ph.D., FENOC endorses some but not all of this report’s conclusions. Additionally, some of Mattson’s conclusions are his personal opinion that the company is unable to endorse or validate. The conclusions FENOC does endorse are not in conflict with the root cause reports. Further, the company’s corrective actions remain effective.

FENOC acknowledges in its response that, given the high level of general interest in events at Davis-Besse and consistent with the company’s practice of open and candid communications with the NRC, earlier communications with the NRC about the Exponent and Mattson reports would have been beneficial. To ensure close and early communications with the NRC, the company will develop a formal process to review technical reports regarding its nuclear stations that are prepared as part of a commercial matter.

The NRC, FENOC and Nuclear Energy Institute have clearly concluded issues raised in these reports do not impact the safe and reliable operations of Davis-Besse and other similar plants.

FENOC will continue working with regulators to resolve any issues around these matters, including meeting publicly with the NRC later this month to discuss the DFI and yesterday’s response.

FENOC is a subsidiary of FirstEnergy Corp. (NYSE: FE), a diversified energy company headquartered in Akron, Ohio. FENOC operates the Beaver Valley Nuclear Power Station in Shippingport, Pennsylvania, the Davis-Besse Power Station in Oak Harbor, Ohio and the Perry Nuclear Power Plant in Perry, Ohio.
