Refer to base procedure NP 10.3.6for safety assessment checklist KSF definitions.

NOTE:

Wheneverfuel has been removedfrom the reactor vessel and refueling cavity, all key safety functions are GREEN ercept spentfuelpool cooling.

KEY SAFETY FUNCTION CRITERIA: No/False = 0, Yes/TIrue = I through 4 REACTIVITY
