HATCH NUCLEAR POWER PLANT, UNITS 1 AND 2 -REQUEST FOR ADDITIONAL INFORMATION REGARDING 60-DAY RESPONSE TO BULLETIN 2011-01, "MITIGATING STRATEGIES" (TAC NOS. ME6438 AND ME6439)

Dear Mr. Ajluni:

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. 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 licensee 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 10, 2011 (ADAMS Accession No. ML111610583), you provided a response to the first set of questions for Edwin I. Hatch Nuclear Power Plant, Units 1 and 2. The second responses were due 60 days after issuance of the bulletin (July 11,2011).

By letter dated July 7,2011 (ADAMS Accession No. ML111890493), you responded to this second set of questions.

M. Ajluni -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 request for additional information within 45 days of the date of this If you have any questions regarding this letter, please feel free to contact me at (301)

Sincerely, William (Billy) leaves, Sr. Project Manager Plant Licensing Branch 11-1 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-321 and Request for Additional cc w/encl: Distribution via NRC Bulletin 2011"()1, "Mitigating Strategies" Reguest for Additional Information Edwin I. Hatch Nuclear Power Plant, Units 1 and 2 Docket Nos. 50-321 and 50-366 1. Describe in detail the maintenance or testing of monitor nozzles, spray nozzles, or similar devices to ensure that they will be functional when needed. The bulletin requested that each licensee describe in detail the maintenance and testing on equipment procured to support the mitigating strategies to ensure that it will be functional when needed. In the context of the mitigating strategies, these devices are commonly used for firefighting, spent fuel pool spray strategies, and as a means to reduce the magnitude of fission product releases.

Your response states that you annually inspect portable hose monitors and fire equipment, but it is not clearif these inspections will ensure that the devices listed above will be functional when needed. 2. Describe in detail how you ensure that a vehicle is available to move the B.5.b portable pump and other B.5.b equipment to the appropriate place when needed. The bulletin requested that each licensee describe in detail the controls for assuring equipment needed to execute the mitigating strategies will be available when needed. A vehicle is typically needed to implement the strategies since the portable pump and other equipment is stored away from target areas. The NRC staff could not determine if you performed activities to ensure that a tow vehicle would be available when needed. Enclosure M. Ajluni -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 request for additional information within 45 days of the date of this If you have any questions regarding this letter, please feel free to contact me at (301)

Sincerely.
