Mirion Technologies (Conax Nuclear) Inc.
402 Sonwil Drive Buffalo, NY 14225-5530 IV. Nature of Potential Defect (Updated):
MTCN's initial Notification reported that material supplied to MTCN by approved sub-suppliers audited to NCA-3800 by MTCN was considered to be ASME qualified source material for Section II and Section III requirements. During triennial Survey of MTCN by the ASME for renewal of our N Type Certificates of Authorization, it was identified by the ASME Survey team that material supplied by two (2) MTCN approved sub-suppliers should be considered unqualified source material. At that time, MTCN's Quality Program did not include the use of unqualified source material.
Since MTCN's initial Notification and subsequent Interim Report, we have completed our Part 21 evaluation and provide the following final information to close out our 10 CFR 21 Report:
- 1. In accordance with ASME NCA-3855.5, MTCN has completed additional independent laboratory material testing on each plate of headerplate and mounting weldment ring material in accordance with ASME SA-240. The additional testing verified that such material met the -requirements of NCA-3800 and therefore does not Impact material safety or Performance of the EPAS delivered. This Is discussed more fully in Section VII below.
