Dear Mr. Hunter:

On May 10, 1985 we verbally notified your Mr. J. Cummins of a deficiency regarding Part 21 notice from Westinghouse that indicates core exit temperature monitoring system thermocouple signal may produce errors.

We have completed our investigation and concluded that the matter is not reportable under 10CFR50.55(e). Records supporting this determination are available for your inspector's review at the CPSES site.

Very truly yours,
