Dear Mr. Horn:
SUBJECT:
EVALUATION OF LICENSEE'S 120-DAY RESPONSE TO SUPPLEMENT NO. 1 TO GENERIC LETTER 87-02 FOR COOPER NUCLEAR STATION (TAC NO. M69439)
By letter dated September 21, 1992, the Nebraska Public Power District responded to Supplement No. I to Generic Letter (GL) 87-02, " Verification-of Seismic Adequacy of ~ Mechanical and Electrical Equipment in Operating Reactors, Unresolved Safety Issue (USI) A-46," for the Cooper _ Nuclear Station (CNS).
Enclosure 1 provides the NRC staff's evaluation of you- letter.
Supplement No. I to GL 87-02 required that all addressees provide,-within 120 days of the date of issuance 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 as to what proceLures and criteria were used to generate the in-structure response spectra 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-2 including both the SQUG
-commitments and the implementation guidance, and therefore considers it
-acceptable. If our interpretation is incorrect, then:in accordance with )
Supplement No. I 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 i g
submittal, but should refer to Enclosure 2 to this letter which provides the D\
