ENCLOSURE 1 NOTICE OF VIOLATION Duke Power Company Docket No. 50-269 Oconee Unit 1 License No. DPR 38 During the Nuclear Regulatory Commission (NRC) inspection conducted May 20 June 9, 1986, a violation of NRC requirements was identified.
The violation involved the licensee's failure to follow procedure during a valve surveillance.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1985),
the violation is listed below:
Technical Specification 6.4.1 requires the station to be operated and main tained in accordance with approved procedures.
Contrary to the above, on April 4, 1986, during surveillance testing on valve 1LP-21, the technician inaccurately signed the procedure step stating that acceptance criteria had been met; whereas, in fact the valve had not passed its exercise test. The valve required 16 seconds to open while the maximum stroke time allowed by the procedure is 15 seconds.
The completed test was subsequently reviewed and approved.
While the valve was technically inoperable during the period April 4 until it passed a surveillance test on June 4, the operability of the low pressure injection system was not in question since the valve is open for normal operation.
The valve would be required to be open following engineered safety features actuation.
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 to this Office within 30 days of the date of the letter transmitting this Notice a written statement or explanation in reply including: (1) admission or denial of the violation, (2) the reason for the violation if admitted, (3) the corrective steps which have been taken and the results achieved, (4) the correc tive steps which will be taken to avoid further violations, and (5) the date when full compliance will be achieved. Where good cause is shown, consideration will be given to extending the response time.
