Subject:
August 15,,1980 NRC Letter to AllWestinghouse Pressurized Water Reactor Licensees Water Level above Reactor Vessel ge-wh de 6
. E. Ginna~uclear P
er Plant, Unit $ 1 Doc
Dear Mr. Novak:
This is in response to your letter concerning'the possibility of exposure of fuel assemblies and control rods during transfer while the plant is in Mode 6 (Refueling).
It has been normal practice at Ginna during refueling mode to main-tain approximately 24.5 feet of water above the reactor vessel flange.
Since the manipulator crane lifts the bottom of the fuel assembly no more than one foot above the reactor vessel flange during the transfer, this results in a water height of approximately 10 feet above the top of-the fuel assembly and control rods at their highest point during transfer.
Thus, our past practice of maintaining the proper refueling water level exceeds the NRC recommenda-tion.
This requirement is not at present part of our Technical Specification.
Our Technical Specifications willbe revised to include the requirements of maintaining at least 23 feet of water above the reactor vessel flange while in refueling mode and our appropriate refueling procedures willbe revised to include this minimum level requirement.
Very truly yours, L. D. White, Jr.
