s CAROLINA POWER & LIGHT COMPANY SHEARON HARRIS NUCLEAR POWER PLANT UNIT NO. 1 PRESSURE BOUNDARY MATERIAL SUPPLIED BY TUBE'LINE CORPORATION NOT MEETING SPECIFICATION REQUIREMENTS ITEM 123 FINAL REPORT April 28, 1983 REPORTABLE UNDER 10CFR50.55(e)
AND 10CFR, PART 21
SUBJECT:
Shearon Harris Nuclear Power Plant, Unit No. 1, 10CFR50.55(e) and 10CFR, Part 21, reportable deficiency. Carbon steel, butt weld pipe caps not supplied in accordance with NCA-3800 or 10CFR, Part 50, Appendix B.
ITEM:
12 each, 2 1/2",
8", and 10" ASME III Code Class 3 pipe caps.
SUPPLIED BY:
Capitol Pipe and Steel Products, 8200 Henderson Road, Charlotte, N. C.
NATURE OF DEFICIENCY:
DDR-1343 documented that the above referenced materials may not have been supplied in accordance with ASME Section III requirements. This was initially evaluated as not reportable per 10CFR, Part 21, or 10CFR50.55(e).
Further investigation into the problem revealed that the fittings were ordered to SA-234 Grade WPB, but were supplied certified to SA-515 Crade 65.
SA-234 requires product analysis and this was not done. To verify compliance with SA-234 Grade WPB, physical and chemical analysis was performed and did not meet specification requirements.
DATE PROBLEM OCCURRED:
Test results were obtained March 21, 1983.
The condition was evaluated as reportable March 25, 1983.
DATE PROBLEM REPORTED:
On March 30, 1983, Mr. K. V. Hate' notified the NRC (Mr. A. Hardin) that this item was reportable pc che provisions of 10CFR50.55(e) and 10CFR, Part 21.
SCOPE OF PROBLEM:
12 each 2 1/2",
8", and 10" pipe caps.
SAFETY IMPLICATION:
Because product analysis was not documented by Tube Line Corporation, the caps were tested for compliance to SA-234 Grade WPB requirements at the Shearon Harris E&E Center testing facilities.
The chemical analysis does not meet SA-234 Grade WPB specification requirements. Also, the tensile strengths are below minimum acceptable limits of the specification.
There is enough variance between the CMTRs provided by Tube Line and the on-site test results to suggest that the material provided by Tube Lines is not the material documented or the CMTRs.
REASONS DEFICIENCY IS REPORTABLE:
Items did not meet specification. The most significant deviation is the low tensile strengths.
Items were ordered as stock fittings and potentially could have been incorporated into many ASME systems.
Potential for failure existed.
Also, as documented in letter from Capitol Pipe and Steel Products to CP&L, dated April 14, 1983, the materials were manufactured to ASTM specifica-tions and were fraudulently supplied as meeting ASME requirements.
CORRECTIVE ACTION:
The items were returned to the vendor, and will be dispositioned as non-ASME materials or scrapped as appropriate. These fittings were repurchased to replace the nonconforming fittings.
Capitol Pipe and Steel Products is:
1.
Attempting to establish traceability of materials from starting material to the finished product.
2.
Tube Line was instructed to provide Capitol Pipe with all known heat numbers supplied to date so that chemical and physical testing could be performed as required by the material specifications.
