Final Report Notification Pursuant To 10 CFR Part 21.21, Regarding Supply Of 6" NPS Sch. 40 Seamless Stainless-Steel Pipe; Manufacturer: Maxim Tubes Company PVT. LTD.; Heat No: N200309AW01, SR No: 7; 9 pcs; 180 feet total procured as unqualified source material for ASME Section III, Subsection NC Class 2 2007 Edition, 2008 Addenda This letter provides a final report in accordance with §21.21 concerning the supply of 6" NPS Sch. 40 Seamless Stainless-Steel Pipe to the Duke/ Progress Energy Catawba Nuclear and McGuire Nuclear Stations.
Mackson Nuclear, LLC subcontracted Tioga Pipe, Inc. (Tioga Pipe) to supply the pipe.
Tioga Pipe performed utilization of unqualified source material in accordance with ASME NCA-4255.5 on Maxim Tubes Company PVT. LTD. material from Tioga's commercial inventory. While the unqualified source material passed all required tests and examinations in accordance with the requirements of ASME NCA-4255.5, the material was identified with multiple linear indications located on the inside diameter of the pipe.
Further evaluation by Tioga Pipe found these indications to be lap-like and thus, rejectable in accordance with ASME SA999 paragraph 28.12. Please see Attachment 1, "Final Report Notification Information per §21.21", for additional details and clarification.
All material supplied from the same heat and lot number from Maxim Tubes Company PVT. LTD. has been identified by Duke, found not be installed, and returned to Tioga Pipe. At this time, all of the defective material is in Tioga's possession and there is no risk of this defective material being installed into a nuclear facility.
If you have any questions, please feel free to contact me at (713) 512-3569 or our Quality Director, Bryan Nichols, at (484) 546-5613.

Duke Energy Carolinas, LLC (Duke Energy)
Catawba Nuclear Station, Units 1 and 2 Catawba Nuclear Slation Duke Energy CN01VP 14800 Concord Road York, SC 29745 10 CFR 21 Request for Mackson Determination of 10 CFR 21 Reportability Catawba Nuclear Condition Report (NCR) 02388864 Catawba Nuclear Station PO 00154619 Rel 00971 RE:
Linear Indications identified on 6" SS ASME SA312, Schedule 40, Piping The purpose of this letter is to formally notify Mackson of a discovery by Duke Energy concerning the above described piping. Material received on PO 00154619 Rel 00971, and issued under Duke Energy CAT ID 149543, was discovered to have linear indications on the ID of the piping during pre-inspection activities at Duke Energy. Catawba Nuclear Station.
The basic component was delivered for use at CNS and issued to craft for pre-fabrication activities. The material was intended to be used in the Duke Class C LD System (ASME Class 3), which is QA Condition 1, Safety Related. The piping was purchased under CATID 149543, which is [PIPE, 6", SS, ASME SA312, TP304, PLAIN ENDS, SEAMLESS OR WELDED, SCH 40, ANSI B36.10, 1001C1AF1D08060, B, ASME SECTION Ill SUBSECTION NC]. The material was identified with multiple linear indications and is associated with Heat
- N200309AW01 (Duke Energy UTC 30197705). The indications range from 1/4: to well over an inch.
Similar indications were not identified on other material from CATID 149543, with a different Heat #, that was also issued for the same project. It should also be noted that piping from the same heat number (N200309NW01) was also supplied to McGuire Nuclear Station on Duke Energy PO 00154619 Rel 009967 & Rel 00978.
This part was procured QA Condition 1 and provided to Duke Energy under the 1 O CFR 50 Appendix B quality assurance program. It is possible that 1 O CFR 21 may require Mackson, as the supplier, to make a report to the NRC. Therefore, Duke Energy requests Mackson review this issue against the reporting criteria of 10 CFR 21 and take appropriate action to assure that Mackson complies with 10 CFR 21 with respect to this issue. Duke Energy requests Mackson provide documentation of its conclusions relative to 1 O CFR 21 reportability for our records within 45-60 days of receipt of this letter.
Letter from Duke Energy to Mackson Page2 Please direct any questions to Sherry Andrews, Catawba Regulatory Affairs, at (803) 701-3424.
