Dear Mr. Pacilio:
On May 11, 2011, the U.S. Nuclear Regulatory Commission (NRC) issued NRC Bulletin 2011-01, "Mitigating Strategies" (Agencywide Documents Access and Management System (ADAMS) Accession No. ML111250360), to all holders of operating licenses for nuclear power reactors, except those that have permanently ceased operation and have certified that fuel has been removed from the reactor vessel. The purpose of the bulletin was to obtain a comprehensive verification that licensees' mitigating strategies to maintain or restore core cooling, spent fuel cooling, and containment following a large explosion or fire were compliant with Title 10 of the Code of Federal Regulations (10 CFR), Section 50.54(hh)(2). The bulletin requested information on the licensee's 10 CFR 50.54(hh)(2) mitigating strategies in light of the recent events at Japan's Fukushima Daiichi facility to determine if (1) additional assessment of program implementation is needed, (2) the current inspection program should be enhanced, or (3) further regulatory action is warranted.
The bulletin required two sets of responses pursuant to the provisions of 10 CFR 50.54(f). The first responses were due 30 days after issuance of the bulletin (June 10, 2011). By letter dated June 8, 2011 (ADAMS Accession No. ML111600096), you provided a response to the first set of questions. The second responses were due 60 days after issuance of the bulletin (July 11, 2011). By letter dated July 8, 2011 (ADAMS Accession No. ML111920162), you responded to the second set of questions.
The NRC staff has reviewed the submitted information and determined that it needs additional information regarding your 60-day response to the bulletin. Please respond to the enclosed request for additional information within 30 days of the date of this letter.
M. Pacilio
