Dear Mr. Eisenhut IRAN Re: Turkey Point Units 3 & %F Nos. 50-250 and 504'ocket license Amendment 251'roposed Refuelin Boron Concentration In accordance with 10 CFR 50.90, Florida Power & Light Company submits herewith three signed originals and forty copies of a request to amend Appendix A of Facility Operating Licenses DPR-31 & 41.

This amendment is submitted to allow a higher boron concentration during refueling. A safety evaluation is attached to support our request The proposed amendment is described 'below and shown on the accompanying Tech-ni:cal Specification pages bearing the date of this letter in the lower right hand corner.

Pa e 3.10-2 The requirement for minimum boron concentration during refueling may be higher than 1950 ppm depend'ing on the core design.

Pa e B3.10-1 The minimum refueling boron concentration is required to maintain at least 10$

shutdown margin and depends on the core design.

Enclosed please find a check for $ 4,400 in accordance with 10CFR 170.22. It has been determined that this represents a Class I and III amendment.

The proposed amendment has been reviewed and approved by the Turkey Point Plant Nuclear Safety Committee and the Florida Power & Light Company Nuclear Review Board.

Very truly yours, Robert E. Uhrig Vice President A/II Advanced Systems & Technology 820ii80508 820ii3 qA, REUiSKMi~c PDR ADOCK 05000250 P PDR  !

B3;10 BASES FOR LIMITING CONDITIONS FOR OPERATION, REFUELING Detailed instructions,, safety precautions and the design of the fuel handling equipment, incorporating buil't-in inter-locks and',safety features, provide assurance that no inci-dent could'ccur during the refueling operations that would result in a hazard to public health and safety- (1) 'hen-ever changes are not being made in core geometry one flux monitor is sufficient. This permits maintenance of the instrumentation. Continuous monitoring of radiation levels and neutron flux provides immediate .indication of an unsafe conditi'on. The residual'eat pump is used to maintain a uniform boron concentration.

A'oron concentration of 1950 ppm was sufficient to maintain the reactor subcri;tical by at least 1(gh,k/k in the cold condition with all rods inserted, and also maintained the core,subcritical with no control rods inserted, for the first core design (2) The required boron concentration may increase depending on the subsequent core design.

The control room operator will be able to inform the manipu-lator operator of any, impending unsafe condition detected from the control, board indicators during fuel movement.

'he cask crane interlocks prevent cask'handling above spent fuel. An excess weight. interlock is provided on the spent fuel bridge crane hoist to prevent movement of more, than one fuel assembly at a time. The spent fuel transfer mechanism can accommodate. only one fuel assembly at a time.
