SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO.
90 TO FACILITY OPERATING LICENSE NO.
DPR-31 AND AMENDMENT NO; 84 TO'FACIL'ITY'OPERATING'LICENSE "NO. DPR-41 FLORIDA'POWER 'AND 'L'IGHT'OMPANY TURKEY POINT PLANT UNIT NOS.
3 AND 4 DOCKET NOS; 50-'250 AND 50-251 INTRODUCTION By letter dated November 5, 1982, Florida Power and Light Company proposed revised Technical Specifications for Turkey Point Units 3 and 4.
The proposed Technical Specification revision is a result of a reduction in the minimum auxiliary feedwater (AFW) flow requirements since the installation of the new Westinghouse model 44F steam generators at Turkey Point Unit 3.
The new model 44F generators will also be installed at Turkey Point Unit 4.
Based on analyses performed by Westinghouse, the minimum required AFW flow to the new steam generators at Turkey Point Units is 373 gpm.
The previous minimum flow requirement with the older model steam generators was 600 gpm.
EVALUATION As a result of the Westinghouse
- analyses, the licensee has proposed to modify the Turkey Point Units 3 and 4 surveillance requirements that are used to verify the operability of the AFW system (Specification 4.10.1) and the bases for the limiting conditions for operation (Specification B 3.8) regarding AFW flow requirements.
In support of the proposed revision to the specifications, the licensee provided the results of the Westinghouse analyses and a safety evaluation of the. proposed change.
The proposed change revises the monthly pump tests such that a flow rate of 373 gpm for 15 minutes will be established to the steam generators from each AFW pump.
The present specification requires a
15 minute test at a flow rate of 600 gpm.
Note that at Turkey Point Unit 4, the 600 gpm flow rate specification will be in effect until the new model 44F steam generators are installed.
SUMMARY
Based on our review of the results of the Westinghouse analyses and the safety evaluation provided by the licensee, and based on our knowledge of the more efficient heat transfer capability of the new model 44F steam generators compared to the older models, we conclude that the reduction in the minimum required AEW flow rate is acceptable.
We, therefore, also conclude that the proposed revisions to the Turkey Point, Units 3 and 4, Technical Specifications (Sections
- 4. 10. 1 and B 3.8) are acceptable.

Environmental Consideration V..
We have determined that the amendments do not authorize a change in effluent types or total amounts nor an increase in power level and will not result in any significant environmental impact.
Having made this determination, we have further concluded that the amendments involve an action which is insignificant fran the standpoint of environmental impact and, pursuant to 10 CFR $51.5(d)(4), that an environmental impact statement or negative declaration and environ-mental impact appraisal need not be prepared in connection with the issuance of these amendments.
Conclusi on We have concluded, based on the considerations discussed above, that:
(1) because the, amendments do not involve a significant increase in the probability or consequences of an accident previously evaluated, do not create the possibility of an accident of a type different from any evaluated previously, and do not involve a significant reduction in a margin of safety, the amendments do not involve a significant hazards consideration, (2) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed
- manner, and (3) such activities. will be conducted in compliance with the Commission's regulations and the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
