SUBJECT:

SURRY POWER STATION, UNIT NOS. 1 AND 2 - REQUEST FOR ADDITIONAL INFORMATION REGARDING 60-DAY RESPONSE TO BULLETIN 2011-01, "MITIGATING STRATEGIES" (TAC NOS. ME6489 AND ME6490)

Dear Mr. Heacock:

On May 11,2011, the U.S. Nuclear Regulatory Commission (NRC) issued Bulletin 2011-01, "Mitigating Strategies" (Agencywide Documents Access and Management System (ADAMS)

Accession No. ML 1112S0360), 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), Part SO, Section SO.S4(hh)(2). The bulletin requested information on licensee 10 CFR SO.S4(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 SO.54(f). The first responses were due 30 days after issuance of the bulletin (June 10, 2011). By letter dated June 10,2011 (ADAMS Accession No. ML 11171A06S), you provided a response to the first set of questions for Surry Power Station, Units 1 and 2. The second responses were due 60 days after issuance of the bulletin (July 11, 2011). By letter dated July 8, 2011 (ADAMS Accession No. ML11192A212), you responded to this second set of questions.

D. Heacock -2 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.

If you have any questions regarding this letter, please feel free to contact Karen Cotton at (301) 415-1438.

Sincerely, Karen Cotton, Project Manager Plant Licensing Branch 11-1 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-280 and 50-281

The bulletin requested that each licensee describe in detail the controls for ensuring equipment supporting the mitigating strategies will be available when needed. The Nuclear Regulatory Commission (NRC) Safety Evaluation documenting the NRC review of your response to Section B.5.b of the Interim Compensatory Measures Order (EA-02-026) states that you use air bottles to manually depressurize the steam generators. The NRC staff could not determine if you performed activities to ensure that this equipment would be available when needed.
