MRc gSq Point Beach Nuclear Plant PBNP SHUTDOWN SAFETY ASSESSMENT AND FIRE CONDITION CHECKLIST Date: May 28,2004 Time: 0200 Preparer: James Hanna LI R 28 NOTE: Refer to baseprocedure NP 10.3.6for safety assessment checklist KSF definitions.

NOTE: Wheneverfuel has been reinovedfrom the reactorvessel and refueling cavity, all key safely functions are GREEN except spentfuelpool cooling.
