l DOCKET 50-266 AND 50-301 l LICENSEE EVENT REPORT 97-022-00 ELECTRICAL 5llORT CIRCUITS DURING A CONTROL ROOM FIRE l COULD AFFECT SAFE S11UTDOWN CAPABILITY j POINT BEACII NUCI EAR PLANT. UNITS 1 AND 2 Enclosed is Licensee Event Report 97-022-00 for Point Beach Nuclear Plant, Units 1 and 2. This report is provided in accordance with 10 CFR 50.73(a)(2)(v)(A),"Any event or condition that alone could have prevented the l fulfillment of the safety function of structures or systems that are needed to shut down the reactor and maintain it in l a safe shutdown condition." This report describes the potential for a postulated control room fire to cause hot I

electrical shorts in motor-operated valve control circuits that could disable the valve and hinder the capability of achieving safe shutdown. Our Appendix R Rebaselining Project team discovered this design condition during review of NRC Information Notice IN 92-18," Potential for Loss of Remote Shutdown Capability During Control Room Fire" If you require additional information, please contact us.
