NOTICE OF VIOLATION Florida Power
& Light Company St.
Lucie 2
Docket Nos.
50-389 License Nos.'PF-16 During an NRC inspection conducted on July 3 through July 30,
- 1994, a
violation of NRC requirements was identified.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions,"
10 CFR Part 2, Appendix C, the violation is listed below:
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 Specification 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.
This is a Severity Level IV Violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, the Florida Power
& Light Company is hereby required to submit a written statement or explanation to the U.S.
Nuclear Regulatory Commission, ATTN: Document Control
- Desk, Washington, D.C.
20555, with a copy to the Regional Administrator, Region II, and a copy to the NRC Resident Inspector at the St. Lucie'acility, within 30 days of the date of the letter transmitting this Notice of Violation (Notice).
This reply should be clearly ma'rked as a "Reply to a Notice of Violation" and should include for the violation: (1) the reason for the violation, or, if contested, the basis for disputing the violation, (2) the corrective steps that have been taken and the results
- achieved, (3) the corrective steps that will be taken to avoid further violations, and (4) the date when full compliance will be achieved.
If an adequate reply is not received within the time specified in this Notice, an order or demand for information may be issued as to why the license should not be modified, suspended, or revoked, or why such other action as may be proper should not be taken.
Where good cause is shown, consideration will be given to extending the response time.
Dated at Atlanta, Georgia this 23 day of August 1994.
