- Core Cooling to YELLOW due to draindown below rod latch height Inventory to YELLOW due to draindown below rod latch height
- Time to Boil changed to 136 min. due to draindown to RPV flange height PBF-1562 Revision 2 1t030/02 Page 2 of 9

COMMENTS:
- Look Ahead: CORE COOLING and INVENTORY will go ORANGE once we draindown to less than 55%
Protected Equipment signs staged for OP14F Reduced Inventory
- RCS Time to Boil is 136 minutes due to draindown to RPV flange level
- Fire Protection Condition IV: Credit is taken for fire rounds as fire prevention contingency.
