APPENDIX A NOTICE OF VIOLATION Arizona Nuclear Power Project Post Office Box 52034
- Phoenix, Arizona 85072-2034 Docket No.
50-529 License No.
NPF-51 As a result of the inspection conducted on October 13, 1986-November 25, 1986 arid in accordance with NRC Enforcement Policy, 10 CFR 2, Appendix C, the following violation was identified:
10 CFR 50.73.b states that a Licensee Event Report must include the cause of each component failure, if kno'wn, following any event or condition that resulted in an engineered safety feature (ESF) actuation.
Contrary to the above, Licensee Event Report 2-86-046, submitted on October 17, 1986, did not include the known failure mode for a steam generator blowdown containment isolation valve, (2JSGBUV500g) which failed to fully close upon receipt of an ESF containment isolation actuation signal on September 22, 1986.
Results of licensee troubleshooting following the event, on September 22, determined that a plugged muffler on the solenoid discharge vent line prevented the containment isolation valve from completing approximately the last 10K of its travel.
This is a Severity Level IV Violation (Supplement I)
Pursuant to the provisions of 10 CFR 2.201, Arizona Public Service Company is hereby required to submit to this office within thirty day's of the date of this Notice, a written statement or explanation in reply, including: (1) the corrective steps which have been taken and the results achieved; (2) corrective steps which will be taken to avoid further items of noncompliance; and (3) the date when full compliance Hill be achieved.
Consideration may be given to extending your response time for good cause shown.
