SUBJECT:

REQUEST FOR EXEMPTIONS FROM CERTAIN REQUIREMENTS IN 10 CFR PART 72 FOR THE NORTH ANNA POWER STATION INDEPENDENT SPENT FUEL STORAGE INSTALLATION - SUPPLEMENTAL INFORMATION NEEDED

Dear Mr. Hartz:

By letter dated July 21, 2011, Virginia Electric and Power Company (Dominion) requested exemptions from the requirements of 10 CFR 72.212(b)(3) and (b)(11). The exemptions were requested for NUHOMS HD Dry Shielded Canisters (DSC), Model Number HD-32PTH, with serial numbers DOM-32PTH-004-C, -005-C, -007-C, -010-C, -013-C, -019-C and GBC-32PTH-011-C due to non-compliance with the terms and conditions of the Transnuclear, Inc., Certificate of Compliance (CoC) 72-1030, Amendment No. 0. At the time of loading, the decay heat limit was exceeded for twelve fuel assemblies. The twelve fuel assemblies are distributed over the seven identified DSCs.

U.S. Nuclear Regulatory Commission staff performed an acceptance review of the exemption request, to determine if the request contains sufficient information to allow the staff to complete the detailed technical review. This letter is to advise you that based on our acceptance review, the request does not contain sufficient information. The information needed to continue our review is described in the enclosure to this letter as a Request for Supplemental Information. In order to schedule our technical review, this supplemental information should be provided by September 14, 2011. If the supplemental information is not received by this date, the review of this request may be delayed. The supplemental information requested and associated timeframe for the Dominion response were discussed with Mr. Thomas Szymanski of your staff on August 25, 2011.

L. Hartz If you have any questions regarding this matter, please contact me at 301-492-3268.

Sincerely,

/RA/
