. N-. Point Beach Nuclear Plant PBNP SHUTDOWN SAFETY ASSESSMENT AND FIRE CONDITION CHECKLIST Date: June 2,2004 Time: 1400 Preparer: John Olvera U I R 28 NOTE: Refer to base procedureNP 10.3.6for safety assessment checklist KSF definitions.

NOTE: WIheneverfuel has been removed from the reactor vessel and refueling cavity, all key safety functions are GREEN except spentfiel pool cooling.

(0-1) NA SFP Temperatures: Subtotal = NA NW NA OF SE NA OF SFP Average Temp NA SFP Time to Boil NA GIVE A BRIEF EXPLANATION OF ANY CHANGE IN SAFETY ASSESSMENT THAT TOOK PLACE:

• One flow path for both Reactivity and Inventory changed from I) charging pump P-2C via the auxiliary charging line, to 2) RIVST to the 'B' Safety Injection train.

• Instrument Air Compressor K-2B removed from Unit 2 protected equipment list for maintenance.

COMMENTS:

• One flow path for both Reactivity and Inventory changed from 1) charging pump P-2C via the auxiliary charging line, to 2) RWST to the '13' Safety Injection train to reflect the isolation of the auxiliary charging line.

• Instrument Air Compressor K-21B removed from Unit 2 protected equipment list for maintenance.
