APPENDIX A NOTICE OF VIOLATION Vermont Yankee Nuclear Power Corporation Docket No. 50-271 Vermont Yankee Nuclear Power Station License No. DPR-28 As a result of the equipment qualification (EQ) inspection conducted on October 19-23, 1987 and in accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (Enforcement Policy 1987), the following violation was identified:

10 CFR 50.49 paragraphs (f) and (g), and paragraph (k) (for DOR Guideline provi'; ion) require that each item of electrical equipment important to safety be qualified and that qualification must be completed no later than Novemter 30, 1985. Contrary to the above on October 23, 1987:

1. Qualification of tha EP/Hypalon cables was not established at the time of tbt inspection in that the qualification test report was invalid because of problems identified in Information Notice 84-44 (inadequate QA program, test equipment not properly calibrated, test deficiencies and test anomalies improperly documented, and test documents improperly controlled).

2. The qualification of 3M tape splices was not established at the time of the inspection in that no type test report nor adequate similarity analysis was available in the EQ file to support the tape splices' qualification.

3. The qualification of Dings brakes in the Limitorque valve opetator was not established at the time of the inspection in that the EQ file did not contain evidence to demonstrate the radiation qualification of the Dings brakes for application inside the drywell.

4. The qualification of GE EB-5 terminal block was not established at the time of the inspection in that 1) the type test report did not demonstrate that this terminal block can perform its safety function because low insulation resistance values were observed during the test; and, 2) no similarity analysis was available in the EQ file for GE EB-5 and GE CR 1518 terminal blocks.

5. The qualification of Rome XLPE/PVC cables was not established at the time of the inspection in that the test conditions did not envelope the required service conditions (303 F for four hours vs. 325' for three hours).
