a. At least once per 7 days when above the preset power level of the RWM and RSCS, and j g.

4.1.3.1.3 All withdrawn control rods shall be determined OPERABLE by demonstrating the scram discharge volume drain and vent valves OPERABLE, when

.the reactor protection system logic is tested per Specification 4.3.1.2, by verifying that the drain and vent valves:

a. Close within 30 seconds after receipt of a signal for control rods to scram, and
