November 23, 1992 Docket Nos. 50-325 and 50-324 Mr. R. A. Watson Senior Vice President Nuclear Generation Carolina Power & Light Company Post Office Box 1551 Raleigh, North Carolina 27602

SUBJECT:

'"ATION OF BRUNSWICK STEAM ELECTRIC PLANT, UNITS 1 AND 2, AY RESPONSE TO SUPPLEMENT N0. 1 TO GENERIC LETTER 87-02 g.m. NOS. M69433 AND M69434)

Enclosure 1 provides the Nuclear Regulatory Commission staff's evaluation of Carolina Power & Light Company's, (the licensee's), response to Supplement No, I to Generic Letter (GL) 87-02 for Brunswick Steam Electric Plant, Units 1 and 2, which was submitted to the staff in a letter dated September 19, 1992.

Supplement No. I to GL 87-02 required that all addressees provide, within 120 days of the issue date of the supplement, either a commitment to use both the Seismic Qualification Utility Group (SQUG) commitments and the implementation guidance described in the Generic Implementation Procedure, Revision 2 (GIP-2), as corrected on February 14, 1992, and as supplemented by the staff's Supplemental Safety Evaluation Report No. 2 (SSER-2) on GIP-2, or else provide an alternative method for responding to GL 87-02. The supplement also required that those addressees committing to implement GIP-2 provide an implementation schedule, and provide the detailed information on procedures and criteria used to generate the in-structure response spectra (IRS) to be used for USI A-46. In addition, the staff requested in SSER-2 that the licensees inform the staff in the 120-day response if they intend to change their licensing basis to reflect a commitment to the USI A-46 (GIP-2) methodology for verifying the seismic adequacy of mechanical and electrical equipment, prior to receipt of the staff's plant-specific safety evaluation resolving USl A-46, Your response is unclear as to whether or not you intend to implement both the SQUG commitments and the implementation guidance. The sta' interprets your response as a commitment to the entire GIP including bot' one SQUG commitments and the implementation guidance, and therefore considers it acceptable. If the staff's interpretation is incorrect, then in accordance with Supplement No. I to GL 87-02, you should provide for staff review, as soon as practicable l prior to implementation, your alternative criteria and procedures for responding to GL 87-02. Additionally, you should not merely follow the l

August 21, 1992, SQUG letter for implementing GIP-2 as stated in your l

submittal, but should refer to Enclosure 2 to this letter which provides the staff's response to the SQUE 'etter. The implementation schedules proposed by 7

you are within the 3-year res.onse period requested by the staff in Supplement Aj No I to GL 87-02 and are therefore acceptable, t i 9212070252 921123 '

Mr. R. A. Watson You indicated that you may change your licensing basis methodology, via 10 CFR 50.59, for verifying the seismic adequacy of new, replacement, and existing electrical and mechanical equipment prior to receipt of a final plant-specific SER resolving USI A-46. The staff recognizes that you may revise your licensing basis in accordance with 10 CFR 50.59 to reflect the acceptability of the USI A-46 (GIP) methodology for verifying the seismic adequacy of electrical and mechanical equipment covered by the GlP. However, if you do not commit to implement both the SQUG commitments and the implementation guidance, and if you have not committed to acceptable alternative criteria and procedures, then the staff does not believe that you have a basis for initiating a 10 CFR 50.59 review, if you have any questions concerning this review, please contact me at (301) ,

504-1457.
