SUMMARY
The Fort Calhoun Station (FCS) operated at a nominal 100% power level during October 1997. On October 17. 1997. as part of the Updated %fety 1
Analysis Report (USAR) verification project. Desig-' Engineering made a preliminary determination that the station batteries may not met the eight-(8) hour loadiry requirement found in the USAR. Procedural guidance was available to reduce DC loads during a station blackout event but was not available for other design basis accidents. At 1755 hours0.0203 days <br />0.488 hours <br />0.0029 weeks <br />6.677775e-4 months <br />. plant managemer.t conservatively declared the batteries inoperable and entered Technical Specification (TS) 2.0.1. which requires the plant to be in Hot Shutdown within six (6) hours. Operations Memorandum 97-11 was immediately issued This allowed TS 2.0.1 to provide guidance to reduce DC electrical loads in accordance with existing emergency operating plan (EOP) procedures.
to be exited immediately after entry. Offsite notifications were completed as required by station procedures. See LER 97-15 for additional details.
During October 1997. no power operated relief valves (PORV) or primary system safety valve challenges or failures occurred.
