SUBJECT:

PALISADES NUCLEAR PLANT - GENERIC LETTER 2008-01, "MANAGING GAS ACCUMULATION IN EMERGENCY CORE COOLING, DECAY HEAT REMOVAL, AND CONTAINMENT SPRAY SYSTEMS," RESPONSE TO EXTENSION REQUEST (TAC NO. MD7856)

Dear Mr. Schwarz:

Generic Letter (GL) 2008-01, "Managing Gas Accumulation In Emergency Core Cooling, Decay Heat Removal, And Containment Spray Systems," requests licensees to submit information to demonstrate that the emergency core cooling, decay heat removal, and containment spray systems are in compliance with the applicable regulatory requirements, and that suitable design, operational, and testing control measures are in place for maintaining this compliance. GL 2008-01 states that each licensee is requested to submit a written response within 9-months to provide requested information and that if a licensee cannot meet the requested 9-month response date, a 3-month written response is required that describes the alternative course of action that it proposes to take, including the basis for the acceptability of the proposed alternative course of action.

By letter dated April 15, 2008, Entergy Nuclear Operations, Inc. (the licensee) stated that it had received verbal concurrence from Mr. Jared Wermiel, Deputy Director, Division of Safety Systems, Nuclear Reactor Regulation, Nuclear Regulatory Commission (NRC), to extend the submittal date of the 3-month response to GL 2008-01, for Palisades Nuclear Plant, to May 13, 2008. This letter however, did not provide any basis for the extension. After further discussions, the licensee modified its response in a letter dated May 1, 2008, to provide the basis for the extension. The extension request was based on evolving expectations related to the 9-month Generic Letter response and the need to reassess those expectations prior to submittal of the 3-month response.

This letter is to formally acknowledge the approval of the requested extension to the due date for submitting the 3-month response to GL 2008-01 and to document the call(s) with the NRC staff. Specifically, you requested an extension for providing the above 3-month response from April 11, 2008, to May 13, 2008, at Palisades Nuclear Plant. The NRC staff finds that your justification to extend the due date for the 3-month written response to GL 2008-01 to May 13, 2008, is acceptable for granting your extension request. This letter does not alter or change the requested 9-month response date of October 11, 2008.

By letter dated May 13, 2008, the licensee submitted a 3-month response to GL 2008-01 for Palisades Nuclear Plant. The NRC staff will evaluate your proposed alternative course of action (3-month response) for responding to GL 2008-01 and will respond appropriately. If you have any questions regarding this letter, please feel free to contact me at (301) 415-8371.

Sincerely,

/RA/ Mahesh Chawla, Project Manager Plant Licensing Branch LPL 3-1 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket Nos. 50-255
