NOTICE OF VIOLATION Consumers Power Company Docket No. 50-255 License No. DPR-20 Palisades Nuclear Generating Plant During an NRC inspection performed from September 24 through November 4, 1991, a violation of NRC requirements was identified.
In accordance with the 11General Statement of Policy and Procedure for NRC Enforcement Actions,"
(10 CFR Part 2, Appendix C, (1991)), the violation is listed below.
Palisades Final Safety Analysis Report, Section 9.3.2.3.3, "Component Cooling System Emergency Operations," describes low pump discharge pressure as an interlock required to automatically start Component Cooling Water Pump P52C during accident conditions if the other pumps have not started *. Pressure switch PS-0918 provides this function.
Palisades Technical Specification 3.4.1 requires, in part, Component Cooling Water Pump P52C shall be operable, as shall all associated heat exchangers, valves, piping and interlocks required to function during accident conditions. This includes pressure switch PS-0918.
Technical Specification 3.4.2 allows one component specified in Technical Specification 3.4.1 to be inoperable, but restricts the duration to 10.5 days unless the reactor is in cold shutdown.
Contrary to the above, Pressure Switch PS-0918 was made inoperable on August 27, 1991, when electrical links were opened as part of a ground fault isolation, and it remained inoperable until September 12, 1991, a period of sixteen days.
This is a Severity Level IV violation (Supplement I).

If an adequate reply is not received within the time specified in this Notice, an order may be issued to show cause why. the license should not be modified, suspended, or revoked, or why such other action as may be proper should not be taken.
