UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 Nicholas Plate Division of Naval Reactors U.S. Department of Energy Washington, DC 20585
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION FOR REVIEW OF THE MODEL NO. MODEL S-6213 POWER UNIT SHIPPING CONTAINER
Dear Nicholas Plate:
By letter dated December 28, 2022 (Agencywide Documents Access and Management System
[ADAMS] Accession No. ML23003A237), you submitted an application to amend Certificate of Compliance No. 9186 for the Model No. S-6213 power unit shipping container transport package to incorporate a new internal pressure cap design for the S-6213 PUSC. To assist with our review, the U.S. Nuclear Regulatory Commission (NRC) staff needs the information identified in the enclosure to this letter.
We request that you provide this information by June 30, 2023. Inform us at your earliest convenience, but no later than June 23, 2023, if you are not able to provide the information by that date. If you are unable to provide a response by June 30, 2023, please propose a new submittal date with the reasons for the delay. Please reference Docket No. 71-9186 and Enterprise Project Identification Number (EPID) No. L-2023-LLA-0000 in future correspondence related to this amendment request. The staff is available to discuss these questions as well as your proposed responses. If you have any questions regarding this matter, feel free to contact me at (301) 415-6877.
Sincerely, Chris Allen, Project Manager Storage and Transportation Licensing Branch Division of Fuel Management Office of Nuclear Material Safety and Safeguards Docket No. 71-9186 EPID No. L-2023-LLA-0000
Enclosure:
Request for Additional Information May 18, 2023 Signed by Allen, William on 05/18/23
Enclosure Request for Additional Information Docket No. 71-9186 Model No. S-6213 Power Unit Shipping Container Transport Package By letter dated December 28, 2022 (Agencywide Documents Access and Management System
[ADAMS] Accession No. ML23003A237), Naval Reactors (the applicant) submitted an application to amend Certificate of Compliance No. 9186 for the Model No. S-6213 power unit shipping container transport package to incorporate a new internal pressure cap design for the S-6213 PUSC. This request for additional information letter identifies information needed by the NRC staff (the staff) in connection with its review of the application. NUREG-2216, Standard Review Plan for Transportation Packages for Spent Fuel and Radioactive Material," was used by the staff in its review of the application.
Each individual request for additional information describes information needed by the staff to complete its review of the application to determine whether the applicant has demonstrated compliance with the regulatory requirements.
STRUCTURAL 2.1 Provide the information necessary to demonstrate how the proposed change to the S-6213 PUSC package design complies with the performance requirements for normal conditions of transport for the penetration test specified in Title 10 of the Code of Federal Regulations (10 CFR) 71.71(c)(10).
For normal condition of transport, 10 CFR 71.71(c)(10) requires the package to be evaluated for the impact of a vertical steel cylinder of 1.25 in diameter, that weights 13 lbs, and is dropped from a height of 40 in onto the exposed surface of the package that is expected to be most vulnerable to puncture. Section 2.6.10 of the safety analysis report states that this requirement was shown to be satisfied for Model 1 and Model 2 container designs of the S-6213 PUSC package in the two referenced SARs associated with the S6W power units. However, considering the change in design, it is not clear how this penetration test requirement was evaluated for the proposed S-6213 PUSC package design and its content. The guidance in NUREG-2216 describes, in part, the information necessary to demonstrate compliance with the regulation and includes the acceptance criteria used during for review.
The above information is necessary to comply with 10 CFR 71.71(c)(10), 71.43(f) and 71.55(d).
2 MATERIALS 7.1 Justify the absence of information pertaining to welding specifications (including location and nondestructive examination) in the new pressure cap replacement kit drawings provided in safety analysis report Appendix A1.4.
Design basis drawings need to provide welding and examination requirements for important to safety components to ensure the fabrication of the package is described in sufficient detail to establish a basis for evaluation, the fabrication is in accordance with established codes and standards to ensure quality assurance, and the fabrication is such that under normal conditions of transport there would be no substantial reduction in the effectiveness of the packaging.
The above information is necessary to comply with 10 CFR 71.31(c), 71.33(a) and 71.43(f).
