Dear Sir:

Please find the enclosed Licensee Event Report (LER) 50-302/97-032-00. This LER discusses a discrepancy where a non safety related solenoid valve was receiving power from a safety related distribution panel without appropriate electrical separation or isolation. The condition was originally identified on April 6,1997 as a documentation discrepancy. Upon further evaluation, FPC determined the configuration of the eler.trical circuit could impact the safety function of the safety related electrical loads on the distribution panel. After completing an engineering evaluation, on October 8,1997, FPC determined that this condition was contrary to the CR-3 design basis. This report is submitted pursuant to 10 CFR 50.73.

Sincerely, Uw M. \N. Rencheck Director Nuclear Engineering and Projects i MWR/pmp i Enclosures xc: Regional Administrator, Region 11 Senior Resident inspector NRR Project Manager 9711070029 971105 l!ll!llll!llllllill!]l!!I.lllllllill.ll
