Staggered Final Request for Additional Information U.S. Department of Transportation Japanese Approval Certificate No. J/2009/AF-96, Revision 1 Docket No. 71-3098 Certificate of Compliance No. 3098 Model No. GP-01 By letter dated May 11, 2020 [Agencywide Documents Access and Management System (ADAMS) Accession No. ML20143A100], and as supplemented on August 5, 2020 (ADAMS Package Accession No. ML20231A505), the U.S. Department of Transportation requested that the U.S. Nuclear Regulatory Commission (NRC) staff perform a review of the Japanese Approval Certificate Number J/2009/AF-96, Revision 1, Model No. GP-01 transport package, and make a recommendation concerning the revalidation of the package for import and export use.

This request for additional information (RAI) identifies information needed by the NRC staff (the staff) in connection with its review of the application. The staff used International Atomic Energy Agency (IAEA) Specific Safety Requirements No. 6 (SSR-6), Regulations for the Safe Transport of Radioactive Material, 2012 Edition, in its review of the application.

The RAI describes information needed by the staff to complete its review of the application and to determine whether the applicant has demonstrated compliance with the regulatory requirements of the IAEA SSR-6, 2012 Edition.

MATERIAL EVALUATION (M)

RAI-M-1 Specify the welding fabrication and inspection standards for all welded joints of the Model No. GP-01 transportation package.

The applicant notes in Chapter I-C.(7), Welding, of the safety analysis report (SAR) that TIG welding is adopted for all the elements of the packaging to be welded. However, the SAR does not identify which standard is used to define the requirements for welding, such as weld procedure qualification, materials, heat treatments, and post-weld inspections.

This information is required to determine compliance with paragraphs 640 and 648 of IAEA SSR-6, 2012 Edition.
