NA GIVE A BRIEF EXPLANATION OF ANY.CHANGE IN SAFETY ASSESSMENT THAT TOOK PLACE:
- We will transition to Fire Protection Condition II when one S/G meets the reflux cooling requirements in SEP 1.1 (S/G tubes drained, vent path available, secondary makeup available, and SIG level above 400 inches). Fire rounds are credited as a fire prevention contingency.
Core Cooling and Inventory willremain YELLOW until the RCPs are bumped.
- Credited flow paths for Reactivity and Inventbry were changed due to use of BAST water to fill/vent RCS.
