May 9, 2008 Mr. Richard M. Rosenblum Senior Vice President and Chief Nuclear Officer Southern California Edison Company San Onofre Nuclear Generating Station P.O. Box 128 San Clemente, CA 92674-0128
SUBJECT:
SAN ONOFRE NUCLEAR GENERATING STATION, UNITS 2 AND 3 -
GENERIC LETTER 2008-01, MANAGING GAS ACCUMULATION IN EMERGENCY CORE COOLING, DECAY HEAT REMOVAL, AND CONTAINMENT SPRAY SYSTEMS, RESPONSE TO EXTENSION REQUEST (TAC NOS. MD7876 and MD7877)
Dear Mr. Rosenblum:
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. In GL 2008-01, the U.S. Nuclear Regulatory Commission (NRC) staff 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 10, 2008, the licensee stated that currently, it plans to meet the 9 month response date; however, based upon evolving industry clarification regarding the need for detailed confirmatory walkdowns, Southern California Edison Company (SCE) has decided to re-evaluate its plans for meeting GL 2008-01 requirements. As a result, SCE spoke with the NRCstaff as stated above to request the additional time to further evaluate the planned course of action and to prepare and submit a 3-month GL 2008-01 response, if necessary. This was conveyed during a telephone call by your Plant Licensing Staff to Mr. Jerry Wermiel, NRC Deputy Director of Safety Systems. Mr. Wermiel agreed to an extension for the submittal of the "3-month response" to GL 2008-01 from April 11, 2008, to May 16, 2008.
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 with the NRC staff. Specifically, SCE requested an extension for providing the above 3-month response from April 11, 2008, to May 16, 2008, at San Onofre Nuclear Generating Station, Units 2 and 3.
The NRC staff finds that the justification to extend the due date for the 3-month written response to GL 2008-01 to May 16, 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. The NRC staff will evaluate SCE alternate plans (3-month response) for responding to GL 2008-01 after receipt and will respond appropriately.
If you have any questions regarding this issue, please feel free to contact Kaly Kalyanam, Project Manager at 301-415-1480.
Sincerely,
/RA/
