U. S. Nuclear Regulatory Commission Region III 799 Roosevelt Road Glen Ellyn, Illinois 60137 Attention:
Mr. J. G. Keppler Regional Administrator RE:
WM. H. ZIMMER NUCLEAR POWER STATION UNIT 1 10CFR50.55(e) - ITEM M ANCHOR-DARLING VALVES WITH ANTI-ROTATION DEVICES - DOCKET No. 50-358, CONSTRUCTION PERMIT NO. CPPR-88, W.O. #57300 JOB E-5590 FILE NO. NRC-8, M-42 Gentlemen:
This letter constitutes an interim report concerning the subject condition initially reported to the Commission under the requirements of 10CFR50.55(e).
CG&E Nonconformance Report #0-NPD-82-2140-E was generated which noted that motor operated Anchor-Darling valves with anti-rotational devices were subject to operational failure if the set screw holding the stem collar in place should loosen.
An engineering evaluation has determined that because this con-dition could potentially affect the safety of operations, this item is considered reportable.
The CG&E Nuclear Production Department is presently considering mea:sures for preventing such an occurrence. Among the corrective actions being considered is the staking of the set screw. A final determination of action to be taken will be made by August 31, 1982, at which time a final report will be suhnitted.
We trust the above will be found acceptable as an interim report under 10CFR50.55(e).
Very truly yours, 8207190161 82070s THE CINCINNATI GAS & ELECTRIC COMPANY DR ADOCK 05000358 PDR By h E. A.
