Point Beach Nuclear Plant PBNP SHUTDOWN SAFETY ASSESSMENT AND FIRE CONDITION CHECKLIST Date: Mlav 26. 2004 Time: 1300 Preparer: Jon Leiker U I R 28 NOTTE: Refer to baseprocedure NP 10.3. 6for safety assessment checklist KSF definitions.

NOTE: Wheneverfuel has been removedfrom the reactorvessel and refueling cavity, all key safetfunctions are GREEN except spent fuel pool cooling.

3. Temporary power available to one SFP cooling pump, G-05 available, and SFP time to boil 2 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. (0-1) NA SFP Temperatures: Subtotal = NA 0

NW NA F 0

SE NA F 0

SFP Average Temp NA F SFP Time to Boil NA GIVE A BRIEF EXPLANATION OF ANY CHANGE IN SAFETY ASSESSMENT THAT TOOK PLACE:

• TTB was calculated from SEP-i with vessel level at %pipe and the 1.3 multiplier for being refueled. Note that TTB curve based on 50 days post shutdown was conservatively used (CAP056964).
