SUPPLEMENTARY INFORMATION:

The U.S. Nuclear Regulatory Commission (NRC or the Commission) has granted the request of Pacific Gas and Electric (the licensee) to withdraw its application dated October 24, 2011 (ADAMS Accession No. ML11326A070), as supplemented by letters dated March 30, April 12, April 30, and June 18, 2012 (ADAMS Accession Nos. ML12093A043, ML12104A022, ML12122A012, and ML12171A233, respectively), for a proposed amendment to Facility Operating License Nos. DPR-80 and DPR-82 for the Diablo Canyon Power Plant, Units 1 and 2, located in San Luis Obispo County, California.

The proposed amendment would have modified the facility Technical Specification 3.3.5, Loss of Power Diesel Generator Start Instrumentation, to correct the nonconservative first level undervoltage relays limits contained in Surveillance Requirement 3.3.5.3; revise the Final Safety Analysis Report Update (FSARU) Appendix 6.2D and Sections 6.3, 15.3, and 15.4;

revise the loss-of-coolant accident control room operator and offsite dose analysis of record described in the FSARU; and provide a new process for revising input values to this analysis.

The Commission had previously issued a Notice of Consideration of Issuance of Amendment published in the Federal Register on May 15, 2012 (77 FR 28632). However, by letter dated September 27, 2012 (ADAMS Accession No. ML12272A098), the licensee withdrew the proposed change.

For further details with respect to this action, see the application for amendment dated October 24, 2012, as supplemented by letters dated March 30, April 12, April 30, and June 18, 2012, and the licensees letter dated September 27, 2012, which withdrew the application for license amendment.

Dated at Rockville, Maryland, this 3rd day of October, 2012.

For the Nuclear Regulatory Commission.
