,V' APPENDIX A NOTICE OF VIOLATION Maine Yankee Atomic Power Company Docket No. 50-309 License No. DPR-36 As a result of the inspection conducted on December 1-26, 1980 and in accordance with the Interim Enforcement Policy, 45 FR 66754 (October 7,1980), the follow-ing violation was identified:
10 C ' 50.59 states in part, "The holder of a license...may (i) make changes in the tacility as described in the safety analysis report...without prior comis-sion approval, unless the proposed change involves...an unreviewed safety question.
Further, 10 CFR 50.59 requires the licensee to maintain records of changes in the facility, which include written safety evaluations, which provide the basis for the determination that an unreviewed safety question is not involved. Technical Specification (TS) 5.5.A.6.d states in part, "The Plant Operation Review Comittee (PORC) shall be responsible for... Review of all pro-posed changes to plant systems that affect nuclear safety".
TS 3.6.A.2 requires one operable ECCS train whenever the reactor coolant system temperature and pressure exceed 2100F and 400 psig.
Contrary to the above, the reactor coolant system temperature and pressure were taken above 2100F and 400 psig on December 15, 1980, without an operable ECCS train, since both ECCS trains contained valves whose stroke times exceeded Final Safety Anclysis specified values and the licensee had not mada a determination based on a written safety evaluation that no unreviewed safety question was involved, nor had the PORC reviewed the proposed change.
This is a Severity Level IV violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.:'01, Maine Yankee Atomic Electric Company is hereby required to submit to this office within twenty-five days of the date of this Notice, a written statement or explanation in reply, including (: (1) the corrective steps which will be taken to avoid further violations; and 2) the date when full compliance will be achieved.
Under the authority of Section 182 of the Atomic Energy Act of 1954, as amended, this response shall be submittea under oath or affirmation.
