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.
