RE: WM. H. ZIMMER NUCLEAR POWER STATION -UNIT 1 IE BULLETIN 80-21, VALVE YOKES SUPPLIED BY MALCOLM FOUNDRY COMPANY, INC., DOCKET 50-358, W.O. 57300, JOB E-5590, FILE # 957-3R Gentlemen:

This is an interim response to I.E. Bulletin 80-21 which concerns valve parts that were supplied by the Malcolm Foundry Company, Inc. and did not meet specified hardness requirements.

Fourteen (14) vendors were contacted and have responded (either by letter or verbally) and stated that no Malcolm materials were used in any Zimmer Station Products. With the exception of those furnished by General

' Electric, this completes our investigation of all safety-related valves on the Zimmer Power Station.

General Electric is still investigating vendors of valves they furnished as part of the NSSS system.

i Our final report will be submitted as soon as the General Electric investigations are complete.

Very truly yours, THE CINCINNATI GAS & ELECTRIC COMPANY ro-E.A. BORGMANN T6/[
