Mr. J. G. Keppler Regional Administrator RE:
WM.11. ZIMMER NUCLEAR POWER STATION UNIT 1 10CFR50.55(e)-ITEM M-33-STAMPING OF ASME FITTINGS-DOCKET NO. 50-358, CONSTRUCTION PERMIT NO. CPPR-88, W.O. #57300-957, JOB E-5590 FILE NO. NRC-8, M-33 Centlemen:
This letter constitutes an interim report concerning the subject condition initially reported to the Commission under 10CFR50.55(e).
In the previous interim report, QA-1666, dated March 23, 1982, it was stated that a CC&E audit of its contractor, H. J. Kaiser Company, revealed that the subject SA105GR. II, ASME Class 3 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 superictendent 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 SA105CR. 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 already marked with the material designation. All fittings stamped by Kaiser have been quarantined under Kaiser Nonconformance Report (NR) #E-4016.

i Mr. J. G. Keppler Regional Administrator May 25, 1982 - QA-1780 Page 2 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.
Consequently, CG&E NR #C-QAD-82-1358-E was issued'to quarantine t
other fittings marked with the "high stress" stamp. Disposition of this NR, including a review for those fittings possibly installed in the field, will be completed by July 15, 1982, at which time a report will be submitted.
We trust the above will be found acceptable as an interim report 4
under 10CFR50.55(e).
Very truly yours, THE CINCINNATI CAS'& ELECTRIC COMPANY 4
