UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 November 19, 1992 Docket No. 50-261 Mr. R. A. Watson Senior Vice President Nuclear Generation Carolina Power & Light Company Post Office Box 1551 Raleigh, North Carolina 27602
Dear Mr. Watson:
SUBJECT:
EVALUATION OF THE H. B. ROBINSON STEAM ELECTRIC PLANT, UNIT NO. 2, 120-DAY RESPONSE TO SUPPLEMENT NO. 1 TO GENERIC LETTER 87-02 (TAC NO. M69478) provides the Nuclear Regulatory Commission's evaluation of Carolina Power & Light Company's, (the licensee), response to Supplement No. 1 to Generic Letter (GL) 87-02 for H. B. Robinson Steam Electric Plant, Unit 2, which was submitted to the staff in a letter dated September 19, 1992.
Supplement No. 1 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 USI A-46.
Your response is unclear as to whether or not you intend to implement both the SQUG commitments and the implementation guidance. The staff interprets your response as a commitment to the entire GIP including both the SQUG commitments and the implementation guidance, and therefore considers it acceptable. If the staff's interpretation is incorrect, then in accordance with Supplement No. 1 to GL 87-02, you should provide for staff review, as soon as practicable prior to implementation, your alternative criteria and procedures for responding to GL 87-02. Additionally, you should not merely follow the August 21, 1992, SQUG letter for implementing GIP-2 as stated in your submittal, but should refer to Enclosure 2 to this letter which provides the staff's response to the SQUG letter. The implementation schedules proposed by you are within the 3-year response period requested by the staff in Supplement No. 1 to GL 87-02 and are therefore acceptable.

- 2 soon as practicable prior to implementation, your alternative criteria and procedures for responding to GL 87-02. Additionally, you should not merely follow the August 21, 1992, SQUG letter for implementing GIP-2 as stated in your submittal, but should refer to Enclosure 2 to this letter which provides the staff's response to the SQUG letter. The implementation schedules proposed by your are within the 3-year response period requested by the staff in Supplement No. 1 to GL 87-02 and are therefore acceptable.
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 GIP. 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) 504-2020.
