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

NOTE:

lVhieneverftel has been removed from the reactor vessel and refueeling cavity, all key safety functions are GREEN except spent fuel pool cooling.

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

1.

RCS Boron concentration = 3006 ppm (4/29) a.)

For RSD, RCS boron >Refueling boron concentration specified in unit-specific COLR (TRM 2.1) >2200 ppm b.)

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