Florida Power 8c Light Company, P.O.Box 14000, Juno Beach, FL 33408-0420 FPL SEP 1 5 199'f L-94-233 10 CFR 2.201 U.S.Nuclear Regulatory Commission Attn: Document Control Desk Washington, D.C.20555 Re: St.Lucie Unit 2 Docket No.50-389 Reply to Notice of Violation Ins ection Re ort 94-15 Florida Power and Light Company (FPL)has reviewed the subject inspection report and pursuant to 10 CFR 2.201 the response to the~~~~~notice of violation is attached.Very truly yours, J.H.Goldberg President-Nuclear Division JHG/JWH/kw Attachment cc: Stewart D.Ebneter, Regional Administrator, USNRC Region II Senior Resident Inspector, USNRC, St.Lucie Plant DAS/PSL N1196-94 9409210319 9409'15 PDR ADOCK 0500038rr' PDR an FPL Group company Re: St.Lucie Uni 2 Docket No.50-389 Reply to Notice of Violation Zns ection Re ort 94-15 VIOLATION:

St.Lucie Unit 2 Technical Specification 3.3.1, Table 3.3-1, item 12, required, in part, that 4 channels of TCBs be operable in Mode 1.The associated LCO action statement required that an inoperable channel be placed in the tripped condition within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />;otherwise, the unit was required to be in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.Contrary to the above, on July 14, 1994, when Trip Circuit Breaker TCB-5'failed to open when required, was declared inoperable, and the breaker's failure mode prevented placing the affected channel in the tripped condition, the associated shutdown to Mode 3 was not performed in the required 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.While the unit was ultimately shut down, entrance into Mode, 3 occurred approximately 7-1/2 hours after declaring the Trip Circuit Breaker inoperable.

Further, the shutdown was premised on a management directive, as opposed to a Technical Specif ication requirement.

While the licensee interrupted TCB-5's electrical flow path by opening Trip Circuit Breakers TCB-1, TCB-2, and TCB-6, the subject Technical Specification action statement was prescriptive in requiring that either Trip Circuit Breaker TCB-5 be opened or that the unit be shut down.RESPONSE: REASON FOR VIOLATION FPL concurs that a violation existed.The root cause of the violation was personnel error on the part of Operations Management.

2.CORRECTIVE STEPS TAKEN AND THE RESULTS ACHIEVED The plant was shutdown and entered Mode 3 at 11:06 a.m.on July 14, 1994.3.CORRECTIVE STEPS TO AVOID FURTHER VIOLATIONS The Site Vice President and Plant General Manager have reviewed this event with Operations Management and other key site personnel.

The need for strict adherence to Technical Specifications has been emphasized.

B.Operations Management have be'en made aware that other sources within the Nuclear Division are available to aid in their decision making process when events arise that involve complex or previously unencountered situations.

4.DATE WHEN FULL COMPLIANCE WILL BE ACHIEVED Full compliance was achieved when the plant entered Mode 3 at 11:06 a.m.on July 14, 1994.
