UNITED STATES NUCLEAR REGULATORY COMIVIISSION WASHINGTON, D.C. 20555-0001 February 10, 1998 Mr. Gregory M. Rueger, Senior Vice President and General Manager Pacific Gas and Electric Company Nuclear Power Generation N9B P. O. Box 770000 San Francisco, California 94177
SUBJECT:
PACIFIC GAS 8 ELECTRIC COMPANY'S REVISION TO THE REACTOR VESSEL SURVEILLANCECAPSULE WITHDRAWALSCHEDULE FOR DIABLO CANYON UNIT NO. 2 (TAC NO. M99917)
Dear Mr. Rueger:
By letter dated October 22, 1997, Pacific Gas & Electric Company (PG&E) submitted for NRC approval, their proposed reactor vessel surveillance withdrawal schedule, which was based on the American Society for Testing and Materials (ASTM) E185-73 recommendations and reflected updated fluence information from the surveillance capsules removed in 1994 from Diablo Canyon Unit 2.
The NRC reviewed the PG8E submittal mentioned above, and noted that the revised surveillance program for Diablo Canyon Unit 2 is capable of monitoring the effects of neutron irradiation and the thermal environment on the fracture toughness of ferritic reactor vessel beltline materials for the subject unit.
The NRC veriTied that PG&E's proposed withdrawai schedule for Diablo Canyon Unit 2 satisfies the ASTM E 185-73 Standard.
Since this edition of the standard was current at the time the reactor vessel was purchased, the Diablo Canyon Unit 2 surveillance capsule withdrawal schedule satisfies the requirements of Appendix H to 10 CFR Part 50.
In addition, the NRC noted that PG&E has implemented the ASTM E 185-82 Standard to the maximum extent possible.
Therefore, the NRC found that the revised withdrawal schedule is acceptable for Diablo Canyon Unit 2.
