Point Beach Nuclear Plant PBNP SHUTDOWN SAFETY ASSESSMENT AND FIRE CONDITION CHECKLIST Date: June 3, 2004 Time: 1400 Preparer: John Olvera U I R 28 NOTE: Refer to baseprocedureNP 10.3.6for safety assessment checklist KSF definitions.

NOTE: Wheneverfuel has been removedfrom the reactorvessel a!d refuieling cavity, all key safetyfunctions are GREEN except spentfuelpoot cooling.

4. DHR Capability:

- cavity flooded and internals out OR

- at least one SG available OR

- one fan cooler with Equip hatch installed and personnel hatches capable of being shut (0-1) 1 Subtotal = 6 SPENT FUEL POOL COOLING (ONLY APPLICABLE when starting AND during FULL CORE OFFLOADS)

NOTE: Take creditfor only one P-12 independent offsite power source duringperiods ofsingle X.03 or X-04 availability (*).

Subtotal Condition

1. "A" SFP cooling pump available 0-1 RED with power available from: 2 ORANGE

- G-02 or G-0I via 2B-32 (0-1) NA 3 YELLOW

-(*) an independent off-site power 4-5 GREEN source different than that for Train B below (0-1) NA

2. "B" SFP cooling pump available with power available from:

- G-03 or G-04 via I B42 (0-1) NA

-(*) an independent off-site power source different than that for Train A above (0-1) NA

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 NW NA OF SE NA OF SFP Average Temp NA 0F SFP Time to Boil NA GIVE A BRIEF EXPLANATION OF ANY CHANGE IN SAFETY ASSESSMENT THAT TOOK PLACE:

• Core Cooling returned to GREEN since RHR is re-aligned for Low Head Safety Injection.

• Fire Protection Condition I was entered as RCS temperature exceeded 200'F.

• G-02 to be removed from service for Heat exchanger cleaning.

• Containment integrity established and credited for Containment Safety Function.
