++*++'NITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 2055&4001 September 20, 1999 Mr. Gregory M. Rueger Senior Vice President and General Manager Pacific Gas and Electric Company Diablo Canyon Nuclear Power Plant P. O. Box 3 Avila Beach, CA 93424
SUBJECT:
SAFETY EVALUATIONOF LICENSEE RESPONSE TO GENERIC LETTER (GL) 96-05, DIABLOCANYON POWER PLANT, UNITS 1 AND 2 (TAC NOS.
, M97040 AND M97041)
Dear Mr. Rueger:
On September 18, 1996, the NRC issued Generic Letter (GL) 96-05, "Periodic Verification of Design-Basis Capability of Safety-Related Motor-Operated Valves," requesting each nuclear power plant licensee to establish a program, or to ensure the effectiveness of its current program, to verify on a periodic basis that safety-related motor-operated valves (MOVs) continue to be capable of performing their safety functions within the current licensing bases of the facility.
On November 18, 1996, Pacific Gas and Electric Company submitted a response to GL 96-05 notifying the NRC that it would implement the requested MOV periodic verification program at Diablo Canyon Power Plant, Units 1 and 2. The licensee also provided a summary description of the MOV periodic verification program planned to be implemented at Diablo Canyon.
In a letter dated September 8, 1998, the licensee updated its commitment to GL 96-05.
On March 25, 1999, the licensee provided a response to a request for additional information regarding GL 96-05 forwarded by the NRC staff on December 29, 1998.
The NRC has reviewed the submittals and applicable NRC inspection reports for the MOV program at Diablo Canyon.
Based on our understanding of the licensee's commitment to all three phases of the Joint Owners Group (JOG) program on MOVperiodic verification, the NRC staff finds that the licensee has established an acceptable program to verify periodically the design-basis capability of the safety-related MOVs at Diablo Canyon. As discussed in the enclosed safety evaluation (SE), the NRC staff concludes that the licensee is adequately addressing the actions requested in GL 96-05. The NRC staff may conduct inspections to verify the implementation of the MOVperiodic verification program is in accordance with the licensee's commitments; this SE; the SE dated October 30, 1997, on the JOG program on MOV periodic verification; and the SE dated April 14, 1998, on the Westinghouse Owners Group methodology for ranking IVIOVs by their safety significance.
