E APPENDIX A NOTICE OF VIOLATION

]

l Sacramento Municipal Utility District Docket No. 50-312 Rancho Seco Nuclear Generating Station License No. DPR-54 l l

i During an NRC inspection conducted on May 4-8, 1987, a violation of NRC l requirements was identified. In accordance with the " General Statement of i Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C l (1987), the violation is listed below: 1 A. Technical Specification 4.2.2, Inservice Inspection, requires inservice testing of ASME Class 1, 2, and 3 components to be performed as closely as design permits in accordance with Section XI of the ASME Boiler and Pressure Vessel Code and applicable addenda as required by 10 CFR 1 50.55a(g) except where specific written relief has been granted by the Conrnission.

1. The NRC Safety Evaluation Report for ~the Inservice Testing Program, dated September 25, 1984, provides relief from certain aspects of ASME Section XI for the Turbine Throttle Stop Valves TV-1, -2, -3, and -4 (Relief Exemption PV-14) but requires full fast stroke testing during each cold shutdown, including stroke time measurement.

ASME Section XI, Article IWV 3410, provides requirements for measurement and analysis of power operated valve stroke times and implementation of increased testing frequency and/or corrective action for specified increases in measured stroke time, even though such stroke times may be less than the allowable maxima.

2. The NRC SER, Relief Exemption PV-3, provides relief from certain testing requirements for Reactor Coolant Pump Seal Injection Isolation Valves SIM-019, -020, -021, and -022 but requires that the valves be full stroke tested at each cold shutdown.

Contrary to the above:

1. Actual stroke times for Turbine Throttle Stop Valves TV-1, -2, -3, and -4 have not been measured, documented and evaluated in accordance with ASME Section XI Article IWV 3410 during each cold shutdown since September 25, 1984.

2. Reactor Coolant Pump Seal Injection Valves SIM -019, -020, -021 and

-022 have not been full stroke tested at each cold shutdown since September 25, 1984.

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