NOTE:
W'henever fuel has been removedfrom the reactor vessel and refueling cavity, all key safety functions are GREEN except spentfiuelpool cooling.

- Core Cooling transitioned to, YELLOW when RCS level was raised >55 %.
- Inventory transitioned to YELLOW when RCS level was raised >55 %.
- Time to Boil is 106 minutes,- calculated from SEP-i with vessel level at 3 pipe, 79 0F, 52 days post-shutdown, and the 1.3 multiplier for being refueled. Note that the TTB curve based on 50 days post-shutdown was conservatively used (see CAP056964).
