On November 7, 1983, and February 3,_1984, Consumers Power Company, the licensee for Palisades, provided their response to Generic Letter 83-28 *.
The first letter states that the 11 (RPS) at the Palisades Plant consists of a General Electric relay in series with an A.l len-Bradley contactor.
11 The RPS schematic included as part of the second submittal shows what ap~ears to be a'circuit breaker used as Reactor Trip #2. *The licensee's responses were not suffitiently detailed to permit an evaluatfon of the adequacY of the periodic maintenance and trending programs for the contactors and brea~~i~{Items 4.2.1 and 4.2.2 of the Generic, Letter).
In order that the review of Items 4.2.l and 4.2.2 be completed, the licensee is requested to:*
- 1.

3.1 Verify that maintenance records are kept and periodically re-viewed to identify any trends toward degradation and identify which specific parameters are to be used for trending.
