Mr. J. G. Keppler Regional Administrator RE:
NM. H. ZIMMER NUCLEAR PONER STATION UNIT I 10CFR50.55(e) - ITD1 M-40, PIPING WITH POSSIBLY INDETERMINATE HEAT TREA'IMEtfr - DOCKET NO. 50-358, CN STRUCTION PERMIT NO. CPPR-88, W.O. #57300, JOB E-5590, FILE NO. NRC-8, M-40 Conticmen:
This letter constitutes an interim report concerning the subject condition, initially reported to the Carmission on April 22, 1982, as a potential itcm under the requirements of 10CFR50.55(e).
Approximately 2400' of small bore piping (SA106Gr. B), supplied to the Zimter site by Mutual funufacturing and Supply Co. of Cincinnati, Ohio, and manufactured by Irland Tube Co. of South Plainfield, N. J. is installed in various safety related systans in the plant.
During the course of documentation review, H. J. Kaiser Ibnconformance Report #E-4337 was generated which stated that required heat treatment for the subject pipe was not reported on the Certified Material Test Report (04TR).
Sargent and Lundy (S&L) Specification H-2256, " Erection of Phase II Piping Systcms and Mechanical Equipment", requires the subject piping to meet the requiranents of the 1971 edition of Section III of the ASME Code with 1972 A review of the Code requirements found that heat treatment Winter Addenda.
need not be described on the OfrR. rather, only heat treatments not performed were to be reported.
dated October 24, 1977, Henry J. Kaiser Co. Purchase Order #7070-23116, requires OITR'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 MAY 2 4 G82 8205 280 5 OG S g\\j\\) O
p
.v Mr. J. G. Keppler Ibgional khinistrator (E-1769, May 19,1982 Page 2 referenced specification requirments, this paragraph does not appear in the Code until the Winter 1973 Addanda. In part, this paragraph requires the OfrR to include times and tmperatures of heat treatments.
Section II of the 1971 edition of the ASME Code requires heat treatment 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, OfrR's for two of these indicate that the material was cold-drawn while the OfrR's for the ranining two do not specify to which process the pipe was manufactured. Attspts have been made to resolve this concern with the assistance of the vendor (Ialand Tube) however, CG&E has learned that they are no longer in business.
Investigation of this matter is being addressed through II. J. Kaiser Corrective Action Request (CAR) #083 and Nonconformance E-4337. Pesolution of these itms is expected by July 15, 1982, at which time a report will be subnitted.
We trust the above will be found acceptable as an interim report under 10CFR50.55 (e).
Very truly yours,
