r g g _._ g Powe-Group (713) 676 352l 11 July 1980 s00 00 Mr. Victor Stello, Director Office of Inspection and Enforcement U. S. Nuclear Regulatory Commission Washington, D. C. 20555
Dear Mr. Ste)'o:
Pursuant to the discussion on July 11, 1980 between your Mr. W. A.
Crossman (Region IV) and Mr. A. H. Geisler of Brown & Root, Inc.,
this letter provides written notification of a reportable defect under 10 CFR 21, regarding NPS Industries, Inc. of Secaucus, N. J.
(hereafter referred to as "NPS").
NPS is a supplier of ASME Fection III and B31.1 pipe supports for the South Texas Project Electric Generating Station (STPEGS).
Under STP purchase order no. 35-1197-6017, NPS is performing final design and manufacturing of pipe supports.
Some subassembly forgings for the supports have been shippri to the South Texas site.
Some of the parts for the ASME Section III supports being provided by NPS are manufactured from ASTM A-668, Class C material with ASME Code Case 1644-8 invoked by NPS.
This code case has been accepted by the Nuclear Regulatory Commission in Regulatory Guide 1.85.
Recently NPS submitted to Brown & Root a Supplier Deviation Request (SDR) No. 38.
During the course of our review of NPS SDR-38, two (2) NPS internal Non-Conformance Reports (NCR's), H-15-001 and H 003, were reviewed. These NCR's describe two occurrences where sub-suppliers provided forgings to NPS which are of an AISI grade of steel not consistent with the provisions of the code case, and therefore, in violation of ASME Section III requirements for supports.
In the first case, NCR H-15-001 documents turnbuckles, weldless eye nuts, and clevises forgings supplied to NPS by Cleveland City Forge Co.
These supports' subassembly forgings were furnished as ASTM A-668, Clasu C material with AISI 1035 Chemistry.
Code Case 1644 requires AISI 1020 or 1030 Chemistry be used for ASTM A-668, Class C material.
The NCR was dispositioned "use as is"; use of such forgings with improper AISI Chemistry in welding applications would require special precautions to be imposed during welding to maintain the physical pro erties of the mate. rial.

Page Two NCR H-15-003 documents sway strut eye rods forgings which were also furnished using improper AISI Chemistry for the ASTM A-668, Class C mat erial.
These forgings used AISI 1045 Chemistry instead of AISI 1020 or 1030, required by the Code Case.
This NCR was also dispos-itioned "use as is" on the basis of recertification of the forgings to ASTM A-668, Class F material. As described in the first instance, the material could be deficient in a welded application.
Based on our initial review of this situation, we believe at this time no deficiency exists with the NPS ASME Section III supports for South Texas project, since these supports are in non-welding applications. However, we have initiated a materials evaluation of these supports and will report the results of our evaluation to the NRC.
Relative to the provisions and intent of 10 CFR 21, we believe that the situction with NPS, as described herein, may be of significance in a generic sense.
NPS is an industry supplier of ASME Section III pipe supports.
Based on our review of the NPS NCR's, an undetermined number of ASME Section III supports may have been supplied to other purchasers who may not be aware of the latent material non-compliances in these basic components when used in welding applications.
Additional questions regarding the matter should be addressed to Mr. A. H. Geisler, (713) 676-8201.
Very tru y yours, W.
