Mr. J. G. Keppler Regional Administrator RE:
WM. H. ZIMMER NUCLEAR POWER STATION UNIT 1 10CFR50.55(e) - ITEM M FITTINGS MARKED WITH HIGH-STRESS STAMP - DOCKET NO.
50-358 - CONSTRUCTION PERMIT NO. CPPR-88 W.O. #57300 JOB E-5590 FILE NRC-8, M-33 Gentlemen:
This letter constitutes an interim report concerning the sub-ject condition initially reported to the Commission under 10CFR50.55(e).
In the previous interim report, QA-1780, dated May 25, 1982, it was stated that a CG&E audit of its contractor, H. J. Kaiser Company, revealed that the subject SA105Gr.II, ASME Class 2 fittings were stamped with a letter "N" to indicate the normalized condition of the material.
Two potential problems arose when it was discovered that the fittings were stamped without authorization from the vendor and the marking was accomplished using a "high stress" stamp.
The Kaiser warehouse superintendent has indicated that the fittings stamped were shipped with certification stating that all fittings were indeed normalized. The vendor, Bonney Forge, has stated that all fittings with material designation SA105Gr.II are normalized; this condition being indicated by either the material designation or a letter "N" stamped in the serial number on each fitting. Kaiser was not aware of this practice and independently stamped fittings with the "N" although they were al-ready marked with the material designation. All fittings stamped by Kaiser have been quarantined under Kaiser Nonconformance Report (NR)
- E-4016.
CG&E further investigated this condition and discovered other fittings that were stamped with a "high stress" stamp but are not included in this NR.

Mr. J. G. Keppler Region III July 8, 1982 - QA-1859 Page 2 CG&E NR #C-QAD-82-1358-E has been dispositioned to remove all fittings with this stamp from the warehouse. A disposition for fittings possibly installed in the plant remains under investigation. A report will be sub-mitted by September 31, 1982 which will reflect the results of this investi-gation.
We trust the above will be found acceptable as an interim report under 10CFR50.55(e).
Very truly yours, THE CINCINNATI GAS & ELECTRIC COMPANY By E. A. Borgmann Senior Vice President 4
