SUPPLEMENTARY INFORMATION:

The NRC has granted the request of Pacific Gas and Electric Company (the licensee) to withdraw its November 25, 2013, application (ADAMS Accession No. ML13330A557) for proposed amendments 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 amendments would have modified the Diablo Canyon Power Plant TSs to permit the use of RICTs in accordance with TSTF-505, Revision 1 (ADAMS Accession No. ML111650552). The proposed amendments would have, in part, modified selected required actions to permit excluding the completion times in accordance with a new TS-required RICT program.

The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration, published in the Federal Register on December 9, 2014 (79 FR 73111). The licensee provided supplemental information by letters dated February 5 and May 28, 2015, and July 7 and October 27, 2016 (ADAMS Accession Nos. ML15036A592, ML15148A480, ML16189A282, and ML16301A425, respectively). However, the licensee requested to withdraw the application on March 7, 2018 (ADAMS Accession No. ML18066A938).
