Refer to base procedure NP 10.3.6for safety assessment checklist KSFdefinitions.

NOTE:

Wheneverfuel has been removedfrom the reactor vessel and refueling cavity, all key safety functions are GREEN except spent fuel pool cooling.

.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.
