Dear Mr. Hunter:
On October 23, 1984 we verbally notified your Mr. J. Cummins of a deficiency regarding some differential pressure switches which experience set point shifts in excess of specification requirements when operated at temperatures in excess of 2250F.
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, f 0 &
