Jon Leiker (::.U I R 28 NOTE: Refer to base procedure NP 10.3.6for safety assessment checklist AKSF definitions.

NOTE: -Ifien ever fuel has been removedfront the reactor vessel and refueling cavitl, all key safetyfunctions 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 = 3000 ppm a.) For RSD, RCS boron >Refueling boron concentration specified in unit-specific COLR (TRM 2.1) >2200 ppm b.) For CSD and prior to RSD no fuel motion, RCS boron > boron concentration required by OP 3C (0-1) I 0-1 RED

1. Containment integrity (TS 15.1 .D) (Containment 0 RED Operable) {ITS TS 3.6.11 )set (O or 4) 0

2. Containment Closure CL-lE maintained 2d) and closure < time to boil (O or 2) 2 4-5-6

3. No fuel motion (0-1) 1

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) 0 Subtotal = 3 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 of single X-03 or X-04 availability(*).

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

- G-02 or G-01 via 2B-32 (0-1) NA 3 YELLOW

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

- G-03 or G-04 via IB42 (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 SFP Time to Boil NA GIVE A BRIEF EXPLANATION OF ANY CHANGE IN SAFETY ASSESSMENT THAT TOOK PLACE:

Refueling cavity at Rod Latch Height. Rod Latching is complete.

Look-ahead: When Cavity is drained to below Rod Latch height, we will lose one point for Core Cooling (go YELLOW) and two points for Inventory (if CVCS is not yet back, I recommend using the RNYST4RHR flowpath for Inventory instead of Reactivity to keep Inventory YELLOW and turn Reactivity YELLOW).
