February 1, 2023 Richard W. Boyle Radioactive Materials Branch U.S. Department of Transportation 1200 New Jersey Avenue SE Washington, D.C. 20590
SUBJECT:
REQUEST FOR REVALIDATION OF JAPANESE CERTIFICATE OF APPROVAL J/2026/AF-96 -REQUEST FOR ADDITIONAL INFORMATION
Dear Richard Boyle:
By letter dated May 4, 2022 (Agencywide Documents Access and Management System
[ADAMS] Accession No. ML22333A754), as supplemented on November 17, 2022 (ML23020A178), the U.S. Department of Transportation (DOT) requested that the U.S. Nuclear Regulatory Commission (NRC) staff perform a review of the Japanese Certificate of Approval J/2026/AF-96, dated February 7, 2022, for the Model No. MX-6 transport package and make a recommendation concerning the revalidation of the package for import and export use.
In connection with our review, we need the information identified in the enclosure to this letter.
To assist us in scheduling the staffs review of your response, we request that you provide this information 2 months from the date of issuance of this request. Inform us at your earliest convenience, but no later than 3 weeks after issuance of this request if you are not able to provide the information by that timeframe. If you are unable to provide a response 2 months after issuance of this request, our review may be delayed.
Please reference Docket No. 71-3101 and Enterprise Project Identifier No. L-2022-DOT-0002 in future correspondence related to this request. The staff is available to meet to discuss your proposed responses. If you have any questions, I may be contacted at (301) 415-6577.
Sincerely, Signed by White, Bernard on 02/01/23 Bernard White, Senior Project Manager Spent Fuel Licensing Branch Division of Spent Fuel Management Office of Nuclear Material Safety and Safeguards Docket No. 71-3101 EPID L-2022-DOT-0002
Enclosure:
Request for Additional Information
Request for Additional Information Docket No. 71-3101 Model No. MX-6 Japanese Certificate of Approval J/2026/AF-96 By letter dated May 4, 2022 (Agencywide Documents Access and Management System
[ADAMS] Accession No. ML22333A754), as supplemented on November 17, 2022 (ML23020A178), the U.S. Department of Transportation (DOT) requested that the U.S. Nuclear Regulatory Commission (NRC) staff perform a review of the Japanese Certificate of Approval J/2026/AF-96, dated May 6, 2021, for the Model No. MX-6 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 the 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.
Materials Evaluation 2-1 Describe the applicable consensus codes and standards that are followed for design, fabrication, qualification testing, and acceptance inspections of packaging body welds, fuel basket lodgment welds, and top and rear shock absorbing cover welds to ensure that the welds will be capable of maintaining their structural integrity.
Examples of consensus codes and standards that address design, fabrication, qualification testing, and acceptance inspection of safety-related welds for nuclear applications include those published by the American Society of Mechanical Engineers, the American Welding Society, and analogous consensus codes and standards published by national or international standards organizations.
If a consensus code or standard is not followed for design, fabrication, qualification testing, and/or acceptance inspections of certain packaging welds, please describe how the welds for the packaging body, fuel basket lodgments, and top and rear shock absorbing covers are designed, fabricated, qualification tested, and inspected to ensure that the welds will be capable of maintaining their structural integrity.
Background and Reason for RAI The application documents the use of welded metallic items for several packaging components, including the packaging body, the fuel basket lodgments, and the top and rear shock absorbing covers. The staff noted that the application does not include adequate technical information concerning the codes, standards, and/or other specifications that are followed for design and fabrication of welds that are used to join the metallic subcomponents for the packaging body, the fuel basket lodgments, and the top and rear shock absorbing covers.
Enclosure
Section II-C.2 of the application includes some general information on structural strength testing, leakage testing, and nondestructive examination (NDE) activities that are performed for packaging body shell welds that form the containment boundary.
However, the staff noted that this section does not include any information on codes, standards, or quality assurance criteria that are applied for weld qualification tests (e.g.,
mechanical tests of weld samples to ensure the required structural strength) and NDE criteria for inspections of safety-related production welds in packaging components that are placed into service. Further, the staff noted that the general information in Section II-C.2 concerning qualification testing and NDE activities for the packaging body shell welds does not address other safety-related welds such as the other packaging body welds that are not shell welds, the fuel basket lodgment welds, and the welds that join the metallic plates of the shock absorbing covers.
This information is requested in order to determine whether the package meets the requirements in Paragraphs 640 and 648 of IAEA SSR-6, 2012 Edition.
