Re:
St. Lucie Unit 1 Docket No. 50-335 Proposed License Amendment Steam Generator Sleevin In accordance with 10 CFR 50.90, Florida Power and Light Company (FPL) submits herewith a
request to amend Facility Operating License DPR-67 for St. Lucie Unit 1.
The proposed amendment would modify the St. Lucie Unit 1 Technical Specifications to permit repair of steam generator tubes by the installation of mechanical sleeves.
Currently, the St. Lucie Unit 1 Technical Specifications do not include provisions for repair using sleeves with mechanical joints for those steam generator tubes with eddy current indications showing greater than 404 through-wall degradation.
The current. St. Lucie Unit 1 Technical Specification language was established before the sleeving repair method using mechanical joints to maintain the tubes in service was developed.
The proposed Technical Specification changes would specify the requirements for repairing degraded or defective tubes using sleeves with mechanical joints in the St. Lucie Unit 1 steam generators.
Attachment 1 includes the marked-up Technical Specification pages for St.
Lucie Unit 1.
Attachment 2 is a description of the proposed changes.
Attachment 3
is a
"Determination of No Significant Hazards Consideration."
Attachment 4 is Westinghouse Energy Systems proprietary report(
WCAP 12076r entitled "St. Lucie Unit 1
Steam Generator Sleeving Report (Mechanical Sleeves)".
Attachment 5 is an affidavit pursuant to 10 CFR 2.790 requesting proprietary treatment of Attachment 4.
Attachment 6 is Combustion Engineering, Inc. proprietary report, CEN-377(F)-P, copy Number 00002, entitled St. Lucie Unit l Steam Generator Tube Re air U~sin Leak Ti ht Sleeves.
Attachment 7 is an affidavit, pursuant to 10 CFR 2.790 requesting proprietary treatment of Attachment 6.
In accordance with 10 CFR 50.91(b)
(1),
a copy of this proposed license amendment is being forwarded to the state designee for the state of Florida.

The proposed amendment has been reviewed by the St. Lucie Facility Review Group and the FPL Company Nuclear. Review Board.
It is requested that the NRC approve this proposed license
'mendment by December 1989 to permit FPL to use sleeving for the repair of the St. Lucie Unit 1 steam generators during the winter 1990 refueling outage.
