Response to the Diablo Canyon Independent Safety Committee Twenty-second Annual Report on the Safety of Diablo Canyon Nuclear Power Plant Operations–July 1, 2011, to June 30, 2012

Dear Dr. Lam:

Pacific Gas and Electric Company’s (PG&E) response to the Diablo Canyon Independent Safety Committee’s (DCISC) Twenty-second Annual Report on the Safety of Diablo Canyon Operations for the period of July 1, 2011, to June 30, 2012, is provided in the enclosure to this letter.

We are pleased that the DCISC has once again concluded that PG&E operated the Diablo Canyon Nuclear Power Plant (DCPP) safely during the report period. As you are aware, operating the plant conservatively to protect public health and safety is our highest priority, and we will continue to ensure that we fulfill this commitment.

As discussed in the enclosure, we have reviewed and are taking actions to address your recommendation. We welcome the Committee’s recommendations, and believe that addressing them will further contribute to the continued safe operation of DCPP.

Sincerely,
Edward D. Halpin

Recommendations:

R12-1
DCPP should assign a manager with the authority and inclination to develop the DCPP site office and workspace seismic safety policy and devote the resources needed to implement necessary changes to avoid harm to personnel from a seismic event.

PG&E agrees with the DCISC that the safety of Diablo Canyon Plant staff, including from seismic threats, is a critical aspect of the continued safe operation of the facility.

As noted in the Basis for this Recommendation, the specific issues identified by the Committee have been entered into the station’s Corrective Action Program (SAPN 50484562) which will track them to completion.

Additional leadership attention is being applied to assure that actions are taken to address the broader issue of seismic safety concerns not covered by the station’s Seismically Induced System Interaction Program. The Station’s senior leadership team will oversee these issues related to site facilities. Progress will be tracked via the Corrective Action Program and action plans.
