(0-1) NA SFP Temperatures: Subtotal = NA NW NA OF SE NA OF SFP Average Temp NA SFP Time to Boil NA GIVE A BRIEF EXPLANATION OF ANY CHANGE IN SAFETY ASSESSMENT THAT TOOK PLACE:

e Both RCP's have been sufficiently bumped to fill the Steam Generator tubes. This added two points for core cooling and one for inventory, making both GREEN.
