~ WASHINGTON, D.C. 20555-0001 Hay 27, 1997 Hr. Thomas F. Plunkett President, Nuclear Division Florida Power and Light Company Post Office Box 14000 Juno Beach, Florida 33408-0420

SAFETY EVALUATION OF ST.
LUCIE UNIT 1, REFUELING WATER TANK BOTTOH EPOXY LINING RELIEF REQUEST (TAC NO. H97706)
Dear Hr. Plunkett:
By letter dated January 6,
1997, Florida Power 8 Light Company (FPL) requested approval for an alternative refueling water tank (RWT) bottom design.
The Nuclear Regulatory Commission (NRC) had previously granted approval on October 21, 1993, for a temporary non-Code repair for the RWT bottom until the next Unit 1 refueling outage.
FPL subsequently determined that a Code repair of the RWT bottom was not practical during the fall 1994 refueling outage and requested approval of an alternative non-Code repair to correct the through wall leakage of the Unit 1
RWT bottom.
NRC approved the alternative non-Code repair by letter dated November 25, 1994.
The non-Code repair consisted of adding a reinforced vinyl ester liner to the bottom of the RWT.
As part of the approval, the NRC requested that FPL complete ongoing laboratory testing and in-situ inspections to confirm the ultimate capabilities of the lining.
The laboratory testing and in-situ inspections of the vinyl ester liner has been completed and confirmed that the lining meets the manufacturer's specifications for physical and chemical proper ties and is performing as expected.
Therefore, FPL has requested approval of the use of the reinforced vinyl ester liner for the remainder of the second interval and for the third interval.
The staff finds that the fiberglass reinforced vinyl ester liner in the RWT is performing as expected and is'structurally acceptable for continued service.,
FPL has committed to perform visual or hands-on inspection during each refueling outage for the remainder of the second interval.
The lining is a
coatings industry standard with demonstrated capability for the intended application.
Consequently, the staff finds the proposed alternative to an ASHE Code repair for the RWT bottom would provide an acceptabl'e level of quality and safety.
In accordance with the provisions of 10 CFR 50.55a(a)(3)(i ), the alter native to continue with the use of the tank lining along with the proposed inspections, in lieu of a Code repair or replacement, for the remainder of the second 10-year interval is authorized in that the alterative provides an acceptable level of quality and safety.
The request for relief from the, Code requirements for the continued use of the tank lining for the third interval

'- NL'. Thomas F. Plunkett is denied.
FPL will have to 'submit a separate relief request for the third 10-year interval.
FPL will have to determine if the Code requirements for the RWT have changed when FPL commits to a new edition of the Code for the third interval that is scheduled to start in March of 1998.
