Refer to base procedure NP 10.3.6for safety assessment checklist AKSF definitions.
NOTE:
-Ifien ever fuel has been removedfront the reactor vessel and refueling cavitl, all key safety functions are GREEN except spent fuel pool cooling.

NA GIVE A BRIEF EXPLANATION OF ANY CHANGE IN SAFETY ASSESSMENT THAT TOOK PLACE:
Refueling cavity at Rod Latch Height. Rod Latching is complete.
Look-ahead: When Cavity is drained to below Rod Latch height, we will lose one point for Core Cooling (go YELLOW) and two points for Inventory (if CVCS is not yet back, I recommend using the RNYST4RHR flowpath for Inventory instead of Reactivity to keep Inventory YELLOW and turn Reactivity YELLOW).
