Refer to base procedure NP 10.3.6 for safety assessment checklist KSF definitions.
NOTE:
Whf eneverfuel has been removedfromn the reactor vessel and refueling cavity, all key safety functions are GREEN except spentfuelpool cooling.

- Core Cooling to ORANGE due to RCS level < 55 % to remove Nozzle Dams
- Inventory to ORANGE due to RCS level < 55 % to remove Nozzle Dams
- Time to Boil changed to 106 min. due to draindown to 22% RPV level, calculated from SEP-1, Degraded RHR System Capability, with vessel level at 22%, 80 'F, 50 days. and the 1.3 multiplier credit is taken.
