/LLINO/S POWER COMPANY U-0539 iP CLINTON POWER STATION P.O. BOX 678. CLINTON. ILLINOIS 61727 September 17, 1982 Mr. James G. Keppler Director, Region III Office of Inspection and Enforcement U.S. Nuclear Regulatory Commission 799 Roosevelt Road Glen Ellyn, Illinois 60137
Dear Mr. Keppler:
10CFR Part 21 Defect Threaded Pipe Tees Docket No. 50-462/CPPR-137 On December 3, 1980, Mr. A.J. Budnick of Illinois Power notified Mr. H.M. Wescott, US NRC Region III, of a potentially reportable defect per 10CFR Part 21 regarding certain hardware supplied by the Capital Pipe and Steel Products Company.
Based upon an evaluation, Illinois Power is notifying the Nuclear Regulatory Commission of a 10CFR part 21 defect.
This report provides information as required by 10CFR Part 21.21(6)(3).
(i)
A.J. Budnick, Director-Quality Assurance, on December 3, 1980, informed the NRC (Region III) of a potential defect.
W.C. Gerstner, Executive Vice President by means of this report confirms a 10CFR Part 21 defect based on the perfor-mance of an evaluation conducted on the matter.
(ii)
One-half inch stainless steel, 3000 psi threaded pipe tees of ASME SA-182, F-316 material, 50 pieces (iii)
Capital Pipe and Steel Products Company i
301 City Line Avenue Bala Cynwyd, Pennsylvania 19004 (iv)
Material received by the Contraccor (Baldwin Associates) for installation at the Clinton Power Station deviated from the procurement specifications in that ASME SA-182, F-316 material requirements specifies tensile strength of 75,000 psi.
The certificate of compliance received indicated that the received tees conformed to SA-182, F-316 whereas the Certified Material Test Report (CMTR) documented the tensile strength as 73,250 psi.
The safety hazard that might occur as a result of over-stressing the piping material could be of such significance as to potentially reduce the capability to shut down the reactor.

a J.G. Keppler Sep tember 17, 1982 NRC Page 2 of 2 (v). Capital Pipe and Steel Products Company letter of November 26, 1980, informed Baldwin Associates (IPC Contractor) of the material noncompliance.
Baldwin Associates memorandum of December 2,1980, informed Illinois Power Company of the material noncompliance.
(vi)
Since the stainless steel tees (50 pieces) were bought for general purpose use as needed, the end use location and application is unknown.
None of the.tces supplied by the vendor were or are installed'in any Clinton systems.
The-material was not dedicated at the time of purchase.
(vii)
The fifty (50)
" threaded pipe tees have been returned to the Capital Pipe and Steel Products Company by the Contrac-tor.
Any further action which Capital Pipe and Steel Products Company may be taking at this tire is unknown.
(viii)
The subject material is catalog material and could be classified as commercial grade items.
Additionally, the subject material was not dedicated at the time of purchase.
Although, the procurement documents for the material applied the provisions of 10CFR Part 21, this evaluation revealed that the provisions of 10CFR21 may have been misapplied in the procurement process.
Our evaluation of this reportable defect is available for your review at our offices.
I trust that this letter provides sufficient information for your review and analysis of the problem.
Your very truly,
?
