ENCLOSURE 1 NOTICE OF VIOLATION Duke Power Company Docket Nos. 50-269, 270, 287 Oconee Units 1, 2 and 3 License Nos. DPR-38, DPR-47, DPR-55 During the Nuclear Regulatory Commission (NRC) inspection conducted May 20, 1989 -
June 18, 1989, a violation of NRC requirements was identified.
The violation involved two examples of inadequate procedures which resulted in improper operation of the AC Electrical Distribution System.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions" 10 CFR Part 2, Appendix C (1988), the violation is listed below:
Oconee Nuclear Station Technical Specification (TS) 6.4.1 states that the station shall be operated and maintained in accordance with approved procedures and that these procedures shall contain appropriate check-off lists and instructions.
Implicit in this statement is the requirement that these procedures will be adequate to prevent operation of equipment beyond conditions permitted by TS.
Contrary to the above, two operating procedures were not adequate, in that:
A. Operating Procedure (OP) O/A/1107/03, 100 KV Power Supply contained steps which removed Emergency Power Switching Logic (EPSL) Functional Unit 9 from service in violation of TS Table 3.7-1 (Operability Requirements for EPSL circuits). Placing the plant in this lineup caused the plant to be operated in an unanalyzed condition. This occurred during the period from January to June 1989.
None of these periods exceeded 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
B. Performance Test (PT) 2/A/0610/01J, EPSL ES Actuation Keowee Emergency Power Start Test, required placing both supply breakers from Keowee to the Standby Bus in a condition that prevented automatic closure while the remaining Keowee unit was locked out.
This resulted in a violation of TS 3.7.1(b) which requires two independent on-site emergency power paths to be operable. This condition removed all automatic emergency power restoration capabilities to essential loads on the two operating units. This condition has occurred during past refueling outages due to this procedure inadequacy.
This is a Severity Level IV Violation (Supplement I).
