Point Beach Nuclear Plant PBNP SHUTDOWN SAFETY ASSESSMENT AND FIRE CONDITION CHECKLIST Date: Mlav 2. 2(04. Time: 1400. Preparer: John Olvcrai U I R 28 NOTE: Refer to base procedureNP 10.3.6for safety assessment checklist KSF definitions.

NOTE: Wheneverfiuel has been renzovedfrom the reactorvessel andrefueling carity, all key safetyfinctions are GREEN except spent fiel pool cooling.
