Subject:

Request for Extension of Completion Date for Resolution of GL 2004-02 Arkansas Nuclear One - Unit 1 Docket No. 50-313 License No. DPR-51

Dear Sir or Madam:

By letter dated December 21, 2007 (0CNA120703), the NRC approved an extension for actions associated with Generic Letter (GL) 2004-02, Potential Impact of Debris Blockage on Emergency Recirculation During Design Basis Accidents at Pressurized-Water Reactors, for Arkansas Nuclear One (ANO). This extension was requested in Entergy correspondence dated November 7, 2007 (0CAN110701).

The NRC correspondence dated December 21, 2007, for ANO-1, contained approval to complete the analysis for downstream effects in the reactor vessel and strainer head-loss report by the end of April 2008 and a commitment to complete the final strainer certification/qualification reports and update the licensing basis for GSI-191 by the end of June 2008. Entergy has completed the in-vessel downstream effects analysis and strainer head-loss report; however, the remainder of the ANO-1 analyses are not complete. By letter dated February 28, 2008 (0CAN020803), Entergy provided a preliminary supplemental response to GL 2004-02 and committed to provide the final supplemental response by end of July 2008.

In the November 7, 2007, correspondence, Entergy provided the technical and scheduler basis for the extension request. Therefore, Entergy requests an extension until June 30, 2008, to complete the remaining analyses to support GL 2004-02 resolution (including ex-vessel downstream effects analysis) and update the ANO-1 licensing basis, and until July 31, 2008, to provide the final supplemental response.

1CAN040804 Page 2 Revised commitments contained in this submittal are summarized in the attachment. If you have any questions or require additional information, please contact me.

I declare under penalty of perjury that the foregoing is true and correct. Executed on April 24, 2008.
