[CA] To ensure proper plant response. FNP-2-EEP-O. REACTOR TRIP OR SAFETY INJECTION. must be entered upon any SI actuation.
CAUTION:
The first ten steps of FNP-2-ESP-O.2. NATURAL CIRCULATION COOLDOWN TO PREVENT REACTOR VESSEL HEAD STEAM VOIDING. must be performed before continuing with this procedure.
CAUTION:
If RCP seal cooling had previously been lost. the affected RCP should not be started prior to a status evaluation.
