$E NIOR VICE PRESIDENT t
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 I 10CFR50.55(e) - ITEM M PIPING WITH QUESTIONABLE HEAT TREATFENT - DOCKET NO.
50-358, CONSTRUCTION PERMIT NO. CPPR-88, W.O. #57300 JOB E-5590 FILE NO. NRC-8, M-40 Gentlemen:
This letter constitutes an interim report concerning the subject condition, initially reported to the Commission as a potentially report-able deficiency under 10CFR50.55(e).
As stated in our previous report, QA-1769, dated May 19, 1982, approximately 2400' of small bore piping (SA106Gr. B), supplied to the Zimmer site by Mutual Manufacturing and Supply Co. of Cincinnati, Ohio, and manufactured by Leland Tube Co. of South Plainfield, N.J. is installed in various safety related systems in the plant.
During the course of documentation review, H. J. Kaiser Nonconformance Report #E-4337 was generated which stated that required heat treatment for the subject pipe was not reported on the Certified Material Test Report (CMTR).
Sargent and Lundy (S&L) Specification H-2256, " Erection of Phase II Piping Systems and Mechanical Equipment", requires the subject piping to meet the fabrication requirements of S&L Specification H-2255, " Fabricated Phase II Piping," which specifies the 1971 edition of Section III of the ASFE Code with 1972 Winter Addenda. A review of the Code requirements found that heat treatment need not be described on the CMTR, rather, only heat treatments not performed were to be reported.

a Mr. J. G. Keppler Regional Administrator U. S. Nuclear Regulatory Commission Region III July 8, 1982 - QA-1854 Page 2 Henry J. Kaiser Co. Purchase Order #7070-23116, dated October 24, 1977, requires CMTR's for the subject piping to report data in accordance with ASME III, Paragraph NA-3766.4 (no year specified), however, contrary to the above referenced specification requirements, this paragraph does not appear in the Code until the Winter 1973 Addenda. In part, this paragraph requires the CMTR to include times and temperatures of heat treatments.
Section II of the 1971 edition of the ASME Code requires heat treat-ment for all SA106 material which was cold-drawn; hot finished material need not be heat treated. The piping cited in NR #E-4337, includes four different heats of material, CMTR's for two of these indicate that the material was cold-drawn while CMTR's for the remaining two do not specify to which process the pipe was manufactured.
Attempts have been made to resolve this concern with the assistance of the vendor (Leland Tube),
however, CG&E has learned that they are no longer in business.
H. J. Kaiser Corrective Action Report (CAR) #083 was issued to reach a resolution of the purchasing documents discrepancy, however, a resolution is not yet available. CG&E will remove a sample of each heat of material for the performance of destructive examinations to determine if the material was indeed heat treated. These examinations are expected to be completed and CAR #083 is expected to be resolved by October 31, 1982, at which time a final report will be submitted.
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 FKP:as cc:
