Point Beach Nuclear Plant PBNP SHUTDOWN SAFETY ASSESSMENT AND FIRE CONDITION CHECKLIST Date: . April 23,2004 Time: 1700 Preparer. Andrea LUnsglon U I R 28 NOTE:. Refer to base procedureNP 10.3.6for safety assessmentchecklist KSFdefinitions.
NOTE: Wheneverfuel has been removedfrom the reactorvessel and refueling cavity, all key safety functions are GREEN except spentfuel pool cooling.
KEY SAFETY FUNCTION CRITERIA: No/False = 0, Yes/True =1 through 4 REACTIVITY Subtotal Condition
- 1. RCS Boron concentration = 2979 ppm a.) For RSD, RCS boron >Refueling boron concentration specified in unit-specific COLR (ITRM 2.1) >2200 ppm b.) For CSD and prior to RSD no fuel motion, RCSboron>boronconcentrationrequiredbyOP3C (0-1) 1 0-1 RED

- at least one SG available
- one fan cooler with Equip hatch installed and personnel hatches capable of being shut (0-1) 1 Subtotal = 4 SPENT FUEL POOL COOLING (ONLY APPLICABLE when starting AND during FULL CORE OFFLOADS)
NOTE: Take creditforonly one P-12 independent offsitepower source duringperiodsof single X-03 orX-04availabiity(*).
Subtotal Condition
- 1. 'A' SFP cooling pump available 0-1 RED with power available from: 2 ORANGE
- G-02 or G-01 via 2B-32 (0-1) Wta 3 YELLOW an independent off-site power 4-5 GREEN source different than that for Train B below 10-1) n/a
- 2. 'B' SFP cooling pump available with power available from:
- G-3 or G-04 via IB-42 (0-1) n/a
.(*) an independent off-site power source different than that for Train A above
- 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) Wa SFP Temperatures: Subtotal = n/a NW nWa OF SE n/a OF SFP Average Temp nla OF SFP Time to Boil n/a
.I GIVE A BRIEF EXPLANATION OF ANY CHANGE IN SAFETY ASSESSMENT THAT TOOK PLACE:
The upper internals lift is complete. Reactivity and Containment are GREEN. Sump B is being credited for INVENTORY with one makeup path available. INVENTORY flow path is through the RMW/BAST's through the P-2C and AUX. CHG. lines.
RWST level is <16% so the REACTIVITY paths are through the BAST's and the P-2C pump and AUX. CHG. Lines and the BAST's and the P-15A pump.
