SUBJECT:
SPENT FUEL POOL COOLING SYSTEM MODIFICATIONS (GINNA)
By letter dated November 15, 1976, the NRC Staff issued Amendment No.
11 to Provisional Operating License DPR-18 for the R.
E. Ginna Nuclear Power Plant.
This amendment authorized changes in the design of the Ginna spent fuel storage pool to allow an increase in the spent fuel storage capacity from 210 assemblies to 595 assemblies.
Prior to issuance of Amendment No. 11, the staff reviewed the existing spent fuel cooling system at Ginna and determined that it was satisfactory for full core transfer to the pool, after 30 days of incore cooling, until after the normal refueling in 1979.
This would assure that the pool water temperature limit of 150'F, as established by Amendment No. 11, would not be exceeded.
Normal offloads (one-third of the core as opposed to full core transfer)
'could continue after 1979 as long as sufficient incore cooling, after shut-
- down, was accomplished to assure that the 150'F pool limit was not exceeded when the fuel was transferred.
From a practical standpoint, this could mean additional delay and a higher outage cost.
One of the bases for the issuance of Amendment No.
11 to the Ginna license was your commitment to modify the spent fuel cooling system if necessary to maintain conformance to the Technical Specifications.
By letter dated February 13,
- 1980, as supplemented by additional information provided by letter dated June 9, 1981, you requested staff approval of your proposed modifications to the spent fuel pool cooling system.
This seismically designed system would provide substantial addi.tional cooling beyond that.
needed to satisfy present pool capacity, and the existing cooling system and a backup skid-mounted unit would be retained as redundant cooling sources in case the new system should fail.
The Ginna Technical Specifi-cation pool temperature upper limit of 150'F would continue to be satisfied, and even upon loss of the new system under adverse heat load conditions, sufficient time would be available to restore backup cooling before a
temperature of 180'F would be reached.
This temperature is the temperature f the ool was anal zed and found OFFICE/
