f November 25, 1992 Docket No. 50-331 Mr. Lee Liu Chairman of the Board and Chief Executive Officer lowa Electric Light and Power Company P. O. Box 351 Cedar Rapids, Iowa 52406

SUBJECT:

EVALUATION OF DUANE ARNOLD ENERGY CENTER, 120-DAY RESPONSE TO SUPPLEMENT NO. 1 TO GENERIC LETTER 87-02 (TAC NO. M69444)

The enclosure provides the staff's evaluation of the Iowa Electric Light and Power Company's, the licensee, rasponse to Supplement No. I to Generic letter (GL) 87-02 for the Duane Arnold Energy Center (DAEC), which was submitted to the staff in a letter dated September 21, 1992.

Supplement No. I to GL 87-02 required that all addressees provide, within 120 days of the issue date of the supplement, either e commitment to use both the Seismic Qualification Utility Group (SQUG) commitments and the implement-ation guidance described in the Generic Impiementation Procedure, Revision 2 (GIP-2), as cortected on February 14, 1992, and as supplemented by the staff's Supplemental Safety Evaluation Report No. 2 (SSER No. 2) on GIP-2, or provide an alternative method for responding to GL 87-02.

The supplement also required that those addressees committing to implement GIP-2 provide an imple-menation 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 USl 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 resolving USI A-46.

A telephone call was held with members of your staff on November 18, 1992 to discuss your submittal. As a result of that discussion to clarify your respanse, the NRC staff finds your 120-day response to be acceptable.
