Point Beach Nuclear Plant PBNP SHUTDOWN SAFETY ASSESSMENT AND FIRE CONDITION CHECKLIST Date: April 10. 2004 Time: 15(10 Preparer: Keiinj. ltBennett U I R 28 NOTE: Refer to base procedure NP 10.3.6 for safety assessment checklist KSF definitions.

NOTE: Wheneverfitel has been removedfrom the reactor vessel and refueling cavity, all key safety functions are GREEN except spentfuel pool cooling.

Reactor Vessel Level is now ABOVE reduced inventory, therefore Core cooling and inventory changed from orange lo yellow.
