                       AND 

Required Action: (NOTE: Only applicable if the associated control rod scram time was within the limits of Table 3.1.4-1 during the last scram time Surveillance.)
–Declare the associated control rod scram time “slow.”

Completion Time: 1 hour

                        OR

Required Action: Declare the associated control rod INOPERABLE.

Completion Time: 1 hour

Condition: One or more control rod scram accumulators INOPERABLE with Reactor Steam Dome pressure < 600 psig.

Required Action(C.1): Verify all control rods associated with INOPERABLE accumulators are fully inserted.

Completion Time(C.1): Immediately upon discovery of charging water header pressure < 1520 psig.

                        AND

Required Action: Declare the associated control rod INOPERABLE.

Completion Time: 1 hour

Condition: Required action and associated completion time of required action B.1 or C.1 not met.
