RE: WM. H. ZIMMER NUCLEAR POWER STATION UNIT 1

,N'/7% \g 10CFR50.55(e) M-33 STAMPING OF ASME FITTINGS W DOCKET No. 50/358 CONSTRUCTION PERMIT CPPR-88 W.O. #57300 JOB E-5590 FILE NO. NRC-8 Gentlemen:

This letter constitutes an interim report concerning the subject condi-tion initially reported to the Senior Resident Inspector under the require-ments of 10CFR50.55(e).

In the previous interim report, QA-1611, dated February 1, 1982, it was stated that a CG&E audit of its contractor, H. J. Kaiser Company, revealed that the subject SA 105GR. 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 accom-plished using a "high stress" stamp.

The Kaiser warehouse superintendent has indicated that the fittings stamped were ahipped with certification stating that all fittings were indeed normalized. The vendor, Bonney Forge, has stated that all fittings with material designation SA 105 Gr. II are normalized; this condition being ir.dicated by either 'ho material designation or a letter "N" stamped in the serial number on cau. 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.

CC&E has further investigated this condition and has discovered other fittings that were stamped with a "high stress" stamp but are not included in this NR.

3 Consequently, CG&E NR #C-QAD-82-1358-E has been issued to quarantine

) the other fittings which are' marked with the "high stress" stamp. A final report will be submitted 'by May 31, 1982 to address the' disposition and intended corrective action necessary .to resolve this concern.

We trust the above will be found acceptable as an interim report under 10CFR50.55(e).
