Subject:
1981 Full Core Discharge R.
E. Ginna Nuclear Power Plant Docket No. 50-244
Dear Mr. Crutchfield:
The purpose of this letter is to describe, for your infor-mation, our plans for a full core discharge during the 1981 refueling outage.
The full core discharge is necessary to permit examination of the internals of one main coolant pump.
On August 3, 1978 Rochester Gas and Electric Corporation (RG&E) requested approval from the NRC to take credit for lake temperature being less than 80'uring
- a. planned spring refueling.
This would allow a substantial reduction in the time between when the reactor was shutdown and the completion of a full core dis-charge.
NRC approval was given in a letter dated November 27, 1978.
The approval stated for a shutdown before March 2 a spent fuel pool cooling system (SFPCS) capacity of 13.2 MBTU/hr could be used and for a shutdown before May 2 a capacity of 12.0 MBTU/hr could be used.
Since the 1981 refueling outage is scheduled to start on April 18, 1981, the 12.0 MBTU/hr limit will be used.
Using an analysis identical to that presented in our August 3, 1978 request which accounts for the fuel assemblies presently stored in the SFP the entire core can be placed in the SFP after a cooldown time of approximately 17 days and not exceed the 12.0 MBTU/hr limit.
I Very truly yours, hn E. Maier g Qol
