Nuclear regulators find issues in Seabrook's Safety Evaluation Report

The Nuclear Regulatory Commission (NRC) staff has issued its Safety Evaluation Report (SER) with Open Items for the proposed renewal of the operating license for the single unit, 1,295 MWe Seabrook nuclear power plant in Seabrook, N.H.

The open items involve consideration of operating experience and development of pressure temperature limits, alkali-silica reaction in safety-related structures, and aging-management programs for certain safety-related components. The open items must be addressed by the applicant before the staff can complete its review.

The SER documents the NRC staff’s review to date of the license renewal application and the site audit of Seabrook’s aging management programs to address the safety of plant operations during the period of extended operations.

Plant owner NextEra Energy Seabrook LLC submitted an application to the NRC on June 1, 2010, to extend the license by 20 years. The current 40-year license expires March 15, 2030.

After NextEra provides satisfactory information to address the open items, the NRC staff will publish its final conclusions of its technical review of the license renewal application in an update to the SER.
