NW NA F SE NA OF SFP Average Temp NA OF SFP Time to Boil NA GIVE A BRIEF EXPLANATION OF ANY CHANGE IN SAFETY ASSESSMENT THAT TOOK PLACE:

I

• Core Cooling became YELLOW as RHR was re-aligned for Low Hcad Safety Injection.

• Fire Protection Condition I was entered as RCS Temperature exceeded 200 0 F.

• G-02 to be removed from senrice for Heat exchanger cleaning.

• K-2B returned to service after Maintenance.
