UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 February 6! 2013 LICENSEE: Pacific Gas and Electric Company FACILITY: Diablo Canyon Power Plant, Unit Nos. 1 and 2
SUBJECT:
SUMMARY
OF JANUARY 15, 2013, PRE-APPLICATION MEETING WITH PACIFIC GAS AND ELECTRIC COMPANY TO DISCUSS LICENSE AMENDMENT REQUEST RELATED TO DIESEL GENERATOR TECHNICAL SPECIFICATIONS (TAC NOS. MF0368 AND MF0369)
On January 15, 2013, a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of Pacific Gas and Electric Company (PG&E, the licensee) at NRC Headquarters, One White Flint North, 11555 Rockville Pike, Rockville, Maryland. The purpose of the meeting was to discuss PG&E's plans for a license amendment request (LAR) related to diesel generator (DG) technical specification (TS) changes at Diablo Canyon Power Plant, Unit Nos. 1 and 2 (DCPP). The meeting notice and agenda is available in the Agencywide Documents Access and Management System (ADAMS) at Accession No. ML12348A108. The licensee's meeting slide presentation is available at ADAMS Accession No. ML13018A134. A list of attendees is provided in the Enclosure.
The meeting was a follow-up meeting to a public meeting on August 7,2012, on the same subject. The August 7,2012, meeting summary is available at ADAMS Accession No. ML12250A567. PG&E indicated that it would be providing the LAR in the February/March 2013 time frame. PG&E described the changes to the LAR scope since the previous meeting, and provided a discussion of the issues to be resolved by the LAR, and the scope of the TS changes. The following action items resulted from the meeting:
- PG&E took an action to add a discussion to the LAR to confirm that the proposed revised Surveillance Requirements (SRs) will not impact the DG maintenance interval. PG&E will also add a discussion to the LAR regarding whether or not the DG vendor recommends a minimum run time for the DG to reach equilibrium.
If a minimum run time is recommended, it could affect the DG ratings.
- PG&E took an action to provide in the LAR a discussion of why the auxiliary feedwater electrical load, which is the limiting load, is reduced after 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> for the design-basis accident that is used in the DG load analyses.
- Regarding slide 38 in the licensee's handouts, PG&E took an action to provide in the LAR a description of some of the intermittent electrical loads that the DG load analyses assumes to be running simultaneously.
-2
- The NRC staff took an action to discuss and provide feedback to PG&E in the following areas:
Whether or not the LAR should include a statement that it does not contain changes to Reactor Trip System or Engineered Safety Feature Actuation System TS setpoints.
Whether or not the DG frequency bands in SRs 3.8.1.2 and 3.8.1.7 should also be changed. PG&E had stated that it would be proposing a change in the DG frequency bands for SRs 3.8.1.11 and 3.8.1.19 from 61.2 Hz to 60.8 Hz because of a concern related to the rating of the DGs during these SRs that require the DG to be fully loaded. From PG&E's perspective, the DG frequency bands for SRs 3.8.1.2 and 3.8.1.7 do not need to change because the DG is not fully loaded during these surveillances. The NRC staff indicated that it would consider PG&E's position, but the staff did express a concern that if approved, the DG SR frequency bands would be different for different SRs and this proposed change may not be consistent with the analysis or design basis.
