Look ahead #1: When IB-41 is taken OOS, do not take credit for G-01 & G-02, which will lose I point for Power Availability. Make sure 1X-03 is not coincidently OOS.

Look-ahead #2: When reactor cavity level falls below 23 ft above flange, will lose 1 point for Power Availability and will also move to Fire Protection Condition III.

Look-ahead #3: When reactor vessel internals are moved, will lose 1 point for Reactivity, I point for Inventory, and 2 points for Containment (assuming no CFCs are available).
