ENCLOSURE 1 NOTICE OF VIOLATION Duke Power Company Docket Nos. 50-269, 270, 287 Oconee 1, 2, and 3 License Nos. DPR-38, 47, 55 During an NRC inspection conducted on June 28 - July 25, 1992, two violations of NRC requirements were identified. In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the violations are listed below:
A.
Oconee Technical Specification(TS) 6.4.1 requires that the station be operated and maintained in accordance with approved procedures.
Modification procedure TN/5/A/2878/0/0, Addition of Undervoltage Monitoring in Auxiliary Transformer CT-5, required that cable 1EB2T510 be terminated per drawing 0 751-M and OSS-0218.00-00-0004 and independently verified.
Maintenance Directive 7.5.3, Work Request Implementation, requires that disconnection/reconnection of wiring be documented and independently verified on Section V of the work request "Additional Sheet".
- 1.
Contrary to the above, TN/5/A/2878/0/0 was not followed in that on July 13, 1992, cable 1EB2T510 was not terminated per drawing 0-751-M and OSS-0218.00-00-0004.
This resulted in blowing a control power fuse and failure of a relay in the circuitry when the modification was tested.
- 2.
Contrary to the above, on July 17, 1992, Maintenance Directive 7.5.3 was not followed during the implementation of modification package TN/5/A/2917/00/AL1 in that wiring was disconnected during the performance of step 8.9.3 of the procedure and was not documented on Section V of the work request "Additional Sheet".
The procedure step did not require that the wiring be disconnected and the technician lifted the wires to facilitate the ongoing work activity. The wires were then reterminated onto the wrong connection points.
This is a Severity level IV violation (Supplement I).
B.
Oconee Technical Specification 3.7.1 requires two independent on-site emergency power paths consisting of the two Keowee Hydro units, one through the underground path and 9209020158 920821 PDR ADOCK 05000269 G
2 Duke Power Company Docket Nos. 50-269, 270, 287 Oconee 1, 2,
and 3 License Nos. DPR-38, 47, 55 the other through' the overhead path, to be operable when the three Oconee units are greater than 200 degrees Fahrenheit.
TS 3.7.7 allows the three Oconee units to be critical for a period not to exceed 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> with both Keowee units inoperable for unplanned reasons provided the 4160 volt standby buses are energized within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> by a Lee gas turbine through the dedicated 100 kv transmission circuit.
Contrary to the above, the requirements of TS 3.7.7 were not met in that both Keowee units were inoperable for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> i.e, from approximately 2:30 p.m., on July 16 through 3:13 p.m., July 17, 1992, without the 4160 volt standby busses being energized by a Lee gas turbine.
This is a Severity level IV Violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, Duke Power 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, a copy to the NRC Resident Inspector at the facility that is the subject of this Notice, within 30 days of the date of the letter transmitting this Notice of Violation (Notice). This reply should be clearly marked as a "Reply to a Notice of Violation" and should include for each 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.
