Dear Mr. Stello:

1976~

Re: St. Lucie Unit 1 "' H0qggg REGOLAI0@

COWuSSI011 ggI 5edlo5 Docket No. 50-335.

Proposed Amendment to Facilit 0 eratin License DPR-67 In accordance with 10 CFR 50.30, Florida Power and Light Company submits herewith three (3) signed originals and forty (40) con-formed copies of a request to amend Appendix A of Facility Operating License DPR-67.

This submittal proposes Technical Specification changes relating to the surveillance of safety related hydraulic snubbers at St.

Lucie Unit 1. The proposed changes are as described below and as shown on the accompanying Technical Specification pages bearing the date of this letter in the lower right hand corner.

Pa es 3/4 7-31 throu h 3/4 7-38 (Table 3.7-2)

Table 3.7-2 is revised to include the FPL location number for each snubber listed.

On page 7-33, one Mark No. is corrected by changing MS-548-16A to MS-649-304A (FPL No. 039).

it from On page 7-34, three Mark Nos. are corrected by changing them from:

BF-661-4020 to BF-549-17 (FPL No. 052)

SI-969-6198 to MS-549-11 (FPL No. 061)

SI-970-1248 to MS-549-11 (FPL No. 066)

On page 7-36, four Mark Nos. are corrected by changing them from:

5653 HELPING BUILD FLORIDA

II Director of Nuclear Reactor Regulation Attention: Mr. Victor Stello, Director Page Two May 20, 1976 SI-676-250 to SI-676-2481 (FPL No. 087)

SI-676-2475 to SI-676-247 (FPL No. 110)

SI-V-1 to SI-971-6236 (FPL No. 113)

SI-V-1 to SI-972-6240 (FPL No. 114)

On page 7-37, under the column entitled "ESPECIALLY DIFFICULT TO REMOVE," "No" is changed to "Yes" for FPL No. 095. Also, two Mark Nos. are corrected by changing them from:

CC-14-2 to MS-649-313 (FPL No. 102)

CC-21-5 to BF-549-7 (FPL No. 103)

In addition, Mark Nos. CH-3-54 and CH-3-54A are deleted from the Table because they have been replaced with mechanical snubbers.

On page 7-38, the note at the bottom of the page is revised to permit changes to Table 3.7-2 without prior License Amendment provided the conditions of 10 CFR 50.59 are met and the Table is eventually revised by some future amendment.

The proposed amendment has been reviewed and the conclusion reached that it does not involve a significant hazards consideration, therefore, prenoticing pursuant to 10 CFR 2.105 should not be required. A written safety evaluation is attached.

Very truly yours, Robert E. Uhrig Vice President, REU/

SAFETY EVALUATION Introduction This evaluation supports a proposed amendment to Table 3.7-2, "Safety Related Hydraulic Snubbers," such that changes to the table may be made without prior License Amendment provided safety evaluations, documentation, and reporting are performed in accordance with 10 CFR 50.59.

Discussion The present St. Lucie Unit 1 Technical Specifications allow hydraulic snubbers to be added to safety related systems without prior License Amendment. but say nothing about the possibility of replacing safety related hydraulic snubbers with some other type of seismic restraint.

Florida Power and Light Company (FPL) proposes that the specifica-tions be amended as described in the Introduction to this Safety Evaluation so that mechanical snubbers may be used on safety related systems to replace defective hydraulic snubbers without.

first having to obtain permission to do so via a change to Table 3.7-2. Any replacement mechanical snubber will be properly qualified. Safety evaluations, documentation, and reporting will be provided in accordance with 10 CFR 50.59.

The proposed change will provide increased flexibility in ordering spare parts for seismic restraints. It will also permit correction of deficiencies more quickly by authorizing the use of qualified replacement snubbers without having to go through the, more time-consuming license amendment, process.

Conclusion Based on these considerations, (1) the proposed change does not increase the probability or consequences of accidents or mal-functions of equipment important to safety and does not reduce the margin of safety as defined in the basis for any technical specification, therefore, the change does 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 this amendment will not be inimical to the common defense and security or to the health and safety of the public.
