UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 Docket No. 50-255 Mr. Gerald B. Slade Plant General Manager Palisades Plant Consumers Power Company 27780 Blue Star Memorial Highway Covert, Michigan 49043

Dear Mr. Slade:

November 23, 1992

SUBJECT:

SAFETY EVALUATION OF THE PALISADES PLANT 120-DAY RESPONSE TO GENERIC LETTER 87-02, SUPPLEMENT 1 (TAC NO. M69468} provides the Nuclear Regulatory Commission staff's evaluation of Consumers Power Company's (CPCo} response to Supplement No. 1 to Generic Letter (GL} 87-02 for the Palisades Plant, which was submitted to the staff in a letter dated September 21, 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 No. 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 procedures 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 No. 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 (SE} resolving USI A-46.

Your response is. unclear as to whether or not CPCo intends 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 the staff's interpretation is incorrect, then in accordance with Supplement ~o. 1 to-GL 87-02 you shoul~ provide fo~ staff review, as soon as practicable prior to implementation, the 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 schedule proposed ~

by CPCo is within the three-year response period requested by the staff in

~/

Supplement No. I to GL 87-02 and is therefore, acceptable.

However, if.CPCo does not commit to implement both the SQUG commitments and. <

the implementation guidance, and has not committed to any acceptable alternative criteria and procedures, then the staff dcies not believe that* it*

is-feasible,.* at thls time, for CPCo to chang~ its licensing basis in the manner described.

The staff has reviewed your response regarding in-structure response spectra and finds the response adequate and acceptable.
