Glen Ellyn, Illinois 60137 RE: Perry Nuclear Power Plant Standby Diesel Generators DSRV16:

Potential Defect Concerning IEEE 383 Failure in Certain Class IE Circuits (RDC63(82))

Dear Mr. Keppler:

This letter serves as an Interim Report pursuant to 10CFRSC.55(e) concerning a pctential defect in the standby diesel generator system supplied by Transamerica DeLaval, Inc. (TDI).

Initial notification that this problem was being evaluated by The Cleveland Electric Illuminating Company (CEI) was made to your office on November 23, 1982 by Mr. E. Riley of CEI.

DESCRIPTION OF POTENTIAL DEFICIENCY Transamerica DeLaval, Inc. notified CEI that commercial grade wire had been used as Class 1E cable in certain er.gine and panel circuits. This cable has recently failed the IEEE 383 Insulation Flane Test.

An initial review of the circuits in question indicates that the circuits identified by Transamerica DeLaval may perform safety-related functions. Further conversation with DeLaval will be required to determine the consequences if these circuits fail. The Final Report concerning this potential problem will be submitted by March 30, 1983.

Very truly yours, Murray R. Edelman Vice President Nuclear Group MBE:dm cc: Mr. M. L. Gildner NRC Site Office 8301070306 821222 R ADOCK OSOOO S PD DEC 2 7 m2 sfJ 7
