NOTE:

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

NOTE:

IWheneverfitel has been renzovedfroin the reactor vessel and refueling cavity, all key safety functions are GREEN except spent fitel pool cooling.

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