GB Slade General Manager RESPONSE TO THE SUPPLEMENTAL SAFETY EVALUATION OF SYSTEMATIC EVALUATION PROGRAM (SEP) TOPIC III-6 (TAC NO 48725)
NRC letter dated July I2, I99I transmitted the NRC staff evaluation of the Consumers Power Company (CPC) response to six seismic design issues identified during NRC review of the Palisades Integrated Plant Safety Assessment Report (Topic III-6). The evaluation finds our response to the six seismic design issues acceptable except:
I.
Two masonry walls in containment were not properly surveyed (walkdown); and
- 2.
Certain electrical control panels (C-33, MCC-I, MCC-2, and Switchgear Cabinet ID) which were proposed to be qualified by the data experience method should be reanalyzed or should be qualified under the resolution of Unresolved Safety Issue (USI) A-46, Seismic Qualification of Equipment in Operating Plants, using the General Implementing Procedure (GIP) when it is approved by the NRC.
Additionally, the letter requests: (I) the unqualified walls within containment be properly surveyed (by walkdown) before the end of the I992 refueling outage; and (2) that Consumers Power Company either perform a complete reevaluation of electrical control panels C-33, MCC-I, MCC-2, and Switchgear Cabinet ID or choose to address their seismic adequacy through implementation of the GIP resolution of USI A-46 when the GIP is approved.

I In compliance, CPC will complete the proper survey (walkdown) before the end of the 1992 refueling outage, will inform the NRC of the results of that survey, and will qualify the control panels under the approved GIP resolution of USI A-46.
