Dear Mr. Lear:

Re:

Turkey Point Units 3 and 4

Docket Nos.

50-250 and 50-251 Pro'ected Ability to Dischar e Fuel Your letter of February 17, 1976 suggested that we review our inservice inspection (ISI) schedule'n view of our projected ability to discharge fuel.

The results of our review are as follows:

Our current ISI schedule will require discharging fuel at or near the end of the first 10-year ISI interval (1982 for Unit 3 and 1983 for Unit 4).

At that time we are scheduled to conduct inspections which will require dis-charging fuel.

Our projected ability to discharge fuel depends upon the accumulation of spent fuel, the capacity of the spent fuel

pools, and the potential availability of off-site storage or reprocessing facilities.

The Turkey Point nuclear units were initially designed for a 3-region core with extended first cycle operation and annual refuelings thereafter.

Thus, it is expected that approximately'ne-third core will be accumulated per year beginning with the first refueling.

Each spent fuel pit can presently accommodate one and one-third cores with modifications planned to extend this to approximately four cores.

For the purposes of this review, we have assumed that off-site storage or reprocessing facilities will not be available during the current 10-year ISI interval.

Our spent fuel load without off-site relief is projected to be three cores each for Units 3 and 4 in 1982 and 1983 respectively.

Minor changes in reload design, beginning with Cycle 3 for each unit, are expected to slightly reduce HELPING BUILO FLORIOA

Mr. George r, Chief March 8, 1976 Page Two the amount of spent fuel accumulated at each refueling, so the projected spent fuel load of three cores is conservative.

Therefore, at the end of the first 10-year ISI interval, there will be space for at least one more core in each spent fuel pool assuming that our plan to expand pool capacity is approved by the NRC.

Our proposal to modify the spent fuel pools and amend associated Technical Specifications was forwarded to the Nuclear Regulatory Commission on January 28, 1976 in letter L-76-32 from Robert E. Uhrig to the Director, Division of Operating Reactors.

The letter, contains the schedule established for the pool expansion project.

NRC approval of the proposed modification and Technical Specification amendment has been requested by July 1, 1976.

The scheduled project completion dates are September 1,

1977 and April 1, 1978 for Units 3 and 4 respectively.

In summary, assuming our plan to expand spent fuel pool capacity is approved, our current ISI schedule is compatible with our projected ability to discharge spent fuel. If off-site spent fuel storage or reprocessing facilities become operational before the end of our 10-year ISI interval, the spent fuel storage problem will be further alleviated.

Very truly yours, Robert E. Uhrig Vice President REU: nch cc:
