l NOTICE OF VIOLATION

Duquesne Light Company Docket No. 50-412 l Beaver Valley Nuclear Power Station, Unit 2 License No. CPPR-105 EA 86-190 I During an NRC inspection conducted between September 29 and October 3, 1986, a violation of NRC requirements was identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1987), the violation is set forth below

10 CFR 50.55(e) requires, in part, that the Commission be notified within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and with a written report within 30 days, of each deficiency in design and construction which, were it to have remained uncorrected, could have affected adversely the safety of operations at any time throughout the expected lifetime of the plant, and which represents a significant deficiency in construction which will require extensive I redesign or repair to establish the adequacy of the component to perform I its intended safety function. The written report shall include a des- J cription of the corrective actions taken and sufficient information to permit i analysis and evaluation of the deficiency. and of the corrective action.  !

Contrary to the above, Duquesne Light Company (DLC) did not adequately describe, as required by 10 CFR 50.55(e), the corrective actions taken and provide sufficient information to permit analysis and evaluation of a deficiency and of corrective action for the deficiency that, were it to have remained uncorrected, could have affected adversely the safety of operations and that required extensive repair / redesign to establish its adequacy to perform its intended safety function. Specifically:

a. On June 16, 1983, the NRC was notified by DLC that an error was identified in the Westinghouse 7300 Process Protection System involving deficient Temperature Channel Test (NTC) circuit cards at Beaver Valley 2. The final written report of the deficiencies submitted to the NRC on August 26, 1983 did not adequately describe the corrective actions in that the report stated the NTC circuit cards would be replaced. However, NTC circuit cards in safety related Balance-of-Plant applications were subsequently determined to be acceptable and NTC cards in the process protection system were subsequently modified by the installation of an additional circuit board, and the NRC was not notified of this change in corrective actions. -
