SUBJECT:

GRAND GULF NUCLEAR STATION, UNIT 1 - GENERIC LETTER 2008-01, "MANAGING GAS ACCUMULATION IN EMERGENCY CORE COOLING, DECAY HEAT REMOVAL, AND CONTAINMENT SPRAY SYSTEMS,"

RESPONSE TO EXTENSION REQUEST (TAC NO. MD7831)

Dear Sir or Madam:

Generic Letter (GL) 2008-01, "Managing Gas Accumulation In Emergency Core Cooling, Decay Heat Removal, And Containment Spray Systems," was issued by the Nuclear Regulatory Commission (NRC) on January 11, 2008 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML072910759). In GL 2008-01, the NRC requested 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. The 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 licensee's proposed alternative course of action, including the basis for the acceptability of the proposed alternative course of action. The 3-month response was due April 11, 2008.

By letter dated April 10, 2008 (ADAMS Accession No. ML081020366), Entergy Operations, Inc.

(the licensee), stated that it had a telephone conversation with Jared Wermiel, Deputy Director, Division of Safety Systems, Office of Nuclear Reactor Regulation, NRC, on April 10, 2008, in which the licensee requested an extension to the date for the above 3-month response to the GL for the Grand Gulf Nuclear Station, Unit 1 (GGNS). In the call, the licensee verbally requested an extension to May 8, 2008, to provide the 3-month response to the GL so that it can accurately assess the scope of work required to complete the 9-month response to the GL. There is no planned outage for the station prior to the due date for the 9-month response. The licensee stated that it was granted the request.

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 telephone call(s) with the NRC staff. Specifically, Entergy Operations, Inc. requested an extension for providing the above 3-month response from April 11, 2008, to May 8, 2008, for GGNS. The NRC staff finds that the justification for GGNS to extend the due date for the 3-month written response to GL 2008-01 to May 8, 2008, is acceptable, and the extension request is granted. This letter does not alter or change the required 9-month response date of October 11, 2008.

If you have any questions regarding this issue, please contact Jack Donohew, your assigned project manager, at 301-415-1307 or, via email, at jack.donohew@nrc.gov.

Sincerely,

/RA/
