20555 NRC DOCKETS 50-321, 50-366 OPERATING LICENSES DPR-57, NPF-5 EDWIN I. HATCH NUCLEAR PLANT UNITS 1, 2 SCRAM OISCHARGE VOLUME TECHNICAL SPECIFICATIONS Gentlemen:
Georgia Power Company has reviewed your letter of July 7,1980, which requested that we procose Technical Specifications to assure continued operability of the control rod drive system during reactor operation. The present Technical Specifications for Units 1 and 2 place limiting conditions for operation and surveillance requirements on the scram discharge volume scram switches which meet the intent of the suggested model Technical Specifications.
The July 7,1980, NRC letter went on to suggest Technical Specifi-cations on the vent and drain valves, and the rod block and not-drained alarms on the scram instrument volume. The piping geometry at Plant Hatch places the scram switches immediately adjacent to the lower end of the scram discharge volumes, rather than on an instrument volume which is separated from the scram discharge volume, typically by a run of small diameter piping. The scram switches at Plant Hatch are, therefore, able to communicate freely with the scram discharge volume, providing assurance that the scram discharge volume is empty, and thus capable of performing its function of accepting the water discharged from each hydraulic control unit during a scram. The scram discharge volume piping is sized such the sufficient volume is available to assure a complete scram. We, therefore, do not believe that Technical Specifications on the vent and drain valves and the rod block and not-drained alarms would increase reliability of the control rod drive system.
Very truly yours, j kN W. A. Widner RDS/mb s
