28 NOTE:

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

NOTE:

V~henever fuel has been remnovedfromn the reactor vessel and refueling cavity, all key safetyfunctions are GREEN except spentfuelpool cooling.

KEY SAFETY FUNCTION CRITERIA: No/False = 0. Yes/True = I through 4 REACTIVITY
