Re:

Docket Nos. 50-250
& 50-251 In accordance with 10CFR 50-59, Florida Power
& Light Company submits herewith three signed originals and 19 additional copies of a request for authorization of a change in Technical Specifications attached as Appendix A to Facility Operating Licenses DPR-31 and 41.
The proposed changes are set forth in the attached revised Technical Specification page bearing this date in the lower right hand corner, and are as described below:
~Pa e 1-6 Fuel residence time for cycle 1 change "10,000 effective full power hours (EFPH) to 11,800 effective full power hours (EFPH) for Unit 3 and 24,500 EFPH for Unit 4".
In our letter of July 5, 1973, we submitted the analyses of Turkey Point Plant reactor performance with reduced reactor coolant system pressure.
Turkey Point Unit 3 commenced low pressure operation after 4903 effective full power hours.
The analysis has been updated and now shows that after 5,000 EFPH exposure at full pressure and the remainder at reduced pressure the minimum time to clad flattening for Region 3 is predicted to be 11,800 EFPH.
Unit 4 commenced low pressure operation after 2181 EFPH with a predicted minimum time to clad flattening for Region 1 of 24,500 EFPH.

Mr.'l). J. Skovolt April 5, 1974 Extension of the residence time for cycle 1 on Unit 3 will permit the unit to operate at its normal load factor until the planned refueling in
- October, 1974.
Xt will also result in a saving of approximately 1 million barrels of fuel oil.

1.15 INTERIM LIMITS Limitations are imposed upon reactor core power and power distribution beyond previously established design bases consistent with interim bases for core cooling analysis established by the AEC in 1971 and bases for the effects of densification established in November 1972.
Interim power of the reactor core is limited to the values determined in accordance with specification 3.2.
Interim power in MWt equals N x 2200, where N is determined in accordance with Section 6.c. of specification 3.2.
The fuel residence time for cycle 1 shall be limited to 11,800 effective full power hours (EFPH) for Unit 3 and 24,500 EFPH for Unit 4 under low pressure operating conditions.
1.16 LOW PONER PHYSICS TESTS Low power physics tests are tests below a nominal 5% of rated power which measure fundamental characteristics of the reactor core and related instrumentation.
