-.- s APPENDIX A NOTICE OF VIOLATION Duquesne Light Company Docket No. 50-334 Beaver Valley Power Station, Unit 1 License No. DPR-66 As a result of the inspection conducted on March 11 thru April 18, 1986, and in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2,. Appendix C (1985), the following violations were identi-fied:

A. Technical Specification 4.3.3.5 requires remote shutdown monitoring instru-mentation channel TRB-RH-606, RHR Temperature - HX Outlet, to be demonstrated operable by performance of a monthly channel check. Technical Specification 1.10 defines channel check as a qualitative assessment of channel behavior-during operation by observation.

Contrary to the above, the monthly remote shutdown monitoring instrumentation channel check failed to qualitatively assess TRB-RH-606 as inoperable from December 25, 1985 to March 19, 1986, when indicated readings were off-scale low (less than 50 F) at less than expected ambient temperature (70-80 F).

This is a Severity Level IV Violation (Supplement I).

B. Technical Specification 4.3.3.6.1 requires that the fire detection instrumen-tation accessible during normal plant operation for each fire detection zone listed-in Table 3.3-10 shall be demonstrated operable at least once per six' months by performance of a channel functional test. A channel functional test, as defined by Technical Specification 1.11, is the injection of a simulated signal into the channel as close as practical to the sensor (detector) to verify operability including alarm and/or trip functions.

Contrary to the above, on March 26, 1986, it was determined that implementa-tion of OST 1.33.16, Smoke Detector Instrumentation Test, on the smoke detec-tion system in the No. 2 Diesel Generator Room, failed to demonstrate indivi-dual detector operability in that a complete channel functional test was et performed to verify the control room alarm function for each detector. Du; to inadequate testing, the licensee was unaware that detector D100 was in-operable between January 7,1985 and March 26, 1986.

This is a Severity Level IV Violation (Supplement I).

Pursuant to the provisions of 10 CFR 2.201, Duquesne Light Company is hereby re-quired to submit to this office within thirty days of the date of the letter which transmitted this Notice, a written statement or explanation in reply, including (1) the corrective steps which have been taken and the results achieved; (2) cor-rective steps which will be taken to avoid further violations; and (3) the date when full compliance will be achieved. Where good cause is shown, consideration will be given to extending this response time.
