ENCLOSURE 1 NOTICE OF VIOLATION Vermont Yankee Nuclear Power Corporation Docket No. 50-271 Vermont Yankee License No. DPR-28 During the NRC inspection conducted from May 3 to June 13,1998, three violations of NRC requirements were identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violations are listed below:
A.
10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that, activities affecting quality be prescribed by procedures of a type appropriate to the circumstances and that instructions include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished.
Contrary to the above, on June 3,1998, Vermont Yankee procedure OP-2145, Normal 125VDC Operation, used to investigate a DC ground, did not provide adequate instructions regarding the safety systems that would be affected or the steps necessary to restore safety related equipment to its normal alignment. As a result, core spray system valve CS-5A closed during the activity in which was not its normal position.
This is a Severity Level IV violation (Supplement l}
B.
10 CFR 50 Appendix B, Criterion Ill, Design Control, requires, in part, measures be established to assure the design basis for those structures, systems, and components to which this appendix applies are correctly translated into specifications, drawings, procedures, and instructions.
Contrary to the above, in March 1992, the Standby Gas Treatment System fans and associated electrical circuit breakers were aplaced, and the design values for the over-current protection were not adequately translated into procedures and instructions for installation. As a result, the incorrect over-current settings had the potential to affect SGTS operability.
This is a Severity Level IV violation (Supplement 1).
C.
10 CFR 50.72(b)(2)(iii), Four-Hour Reports, requires licensee's to report, within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, any condition that alone could have prevented the fulfillment of the safety function of structures or systems that are needed to control the release of radioactive material.
Contrary to the above, on June 2,1998, the licensee failed to make a required 4-hour notification, after discovering that incorrect circuit breaker settings could have prevented operation of both standby gas treatment system fans.
