[RDC 126(85)]

Dear Mr. Keppler:

This letter serves as the final report pursuant to 10CFR50.15(e) concerning the potential problem with engine control panel air filters supplied by Transamerica Delaval Incorporated (TDI) to Perry Nuclear Power Plant.

Mr. R. C. Knop of your office was notified on January 31, 1985, by Mr. E. Riley of The Cleveland Electric Illuminating Company that this problem was being evaluated per our Deviation Analysis Report 225.

This report contains a description of the deficiency, an analysis of safety implication, and corrective action taken.

Description of Deficiency On January 22, 1985, TDI notified the Nuclear Regulatory Commission under

' 10CFR21 that a potential problem had been identified concerning the air filter for engine control panels. On November 5, 1978, the purchase specification was changed from the polycarbonate transparent bowl to a metal bowl. The polycarbonate bowl is now rated at 150 psig at 125 F and the metal bowl is rated 250 psig at 175 F. When the specification was originally issued, the vendor rated the polycarbonate bowl at 250 psi. The air pressure which the filter will see in operation cycles between 200 and 250 psig at room temperature.
