NA GIVE A BRIEF EXPLANATION OF ANY CHANGE IN SAFETY ASSESSMENT THAT TOOK PLACE:
RWST level is being lowered in preparation for cavity d rain down (will remain >.40%/o level).
Look-ahead: When Cavity is drained to below Rod Latch height, we will lose one point for Core Cooling (will go YELLOW) and two points for Incnto-y (will go YELLOW).
