T'le test included injecting water into the SDV and verifying that the " scram discharge volume not drained" and " rod withdraw block" alarms picked up. The SDV was then drained and both alanns were verified to clear, verifying proper operation of the vent and drain valves. An air injection test was performed to verify proper operation of'the vent lines. All drain and vent valves were verified to be operable and functioning properly, and no residual water was found in the SDV.

Regarding Item #3; a standing order for both Hatch units to make the required verifications following a scram has been issued.

Regarding Item #5; daily SDV monitoring on both Hatch units began on 7/7/80. No residual water has been observed in the SDV to this point.
