NOTE:

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

NOTE:

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

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

RCS Boron concentration = 2888 plrm a.)

For RSD, RCS boron >Refueling boron concentration specified in unit-specific COLR (TRM 2.1) b.)

For CSD and prior to RSD no fuel motion, RCS boron > boron concentration required by OP 3C
