MST-30 Revalidation Application Acceptance Date:
Monday, March 2, 2026 1:07:00 PM NOTE THAT THIS EMAIL WILL BE ENTERED INTO NRC ADAMS AS A PUBLICLY AVAILABLE DOCUMENT
Dear Mr. Vierling,
By letter dated September 19, 2025 (Agencywide Documents Access and Management System [ADAMS] Accession No. ML25266A022), the United States (U.S.) Department of Transportation (DOT) requested the U.S. Nuclear Regulatory Commission (NRC) to provide a recommendation for revalidation of the Japanese Competent Authority Certificate J/159/AF for the Model No. MST-30 package.
The purpose of this e-mail is to provide you the results of the NRC staffs (the staff thereafter) acceptance review of this proposed request. The staff determined that the application contains sufficient technical information to allow the staff to complete a detailed technical review. The acceptance review is also intended to identify any readily apparent deficiencies related to the characterization of the regulatory requirements or package certification basis.
The staff reviewed your application and concluded that it includes technical information insufficient detail to enable the staff to complete its detailed technical review and make an independent assessment regarding the acceptability of the proposed request in terms of regulatory requirements and the protection of public health and safety and the environment.
Given the more limited scope and depth of the acceptance review compared to the detailed technical review, issues that affect the staffs ability to complete the technical review may still be identified despite the acceptance review being deemed adequate. If additional information is needed, you will be notified by separate correspondence.
The staff determined, based on historical data, that the technical review may require approximately 475 hours0.0055 days <br />0.132 hours <br />7.853836e-4 weeks <br />1.807375e-4 months <br /> and 6 months, approximately. To support a more efficient process, the NRC is setting a goal of completing a review in 15% less time and level of effort. Based on that, the staff estimate for this review is approximately 400 staff hours and 4 months.The schedule includes the issuance, if needed, of a request for additional information (RAI) by March 13, 2026, and receiving your response by April 10, 2026. The staff expects to complete the formal review and issue a certificate by June 30, 2026. These estimates are based on the staffs initial review of the application and may change due to several factors, including, unanticipated expansion of the review scope involvement, or if the submittal is provided to the NRC in advance of or concurrently with industry program initiatives or pilot applications.
The schedule above is also based, in part, on RAI responses being provided by the timeline specified, unless another date is agreed upon, RAI responses resolving issues with limited need for follow-up RAIs, and clarification calls being scheduled and conducted promptly, and any additional supporting non-docketed information being provided timely.
To achieve this schedule, the staff intends to engage DOT frequently to resolve emergent issues or challenges that may arise during the staffs review that affect the initial forecasted completion date or result in significant changes to the estimated review hours. The reasons for those changes, along with updated estimates, will be communicated during routine interactions with the assigned project manager and documented accordingly. Should the review experience a delay for other reasons, the staff will endeavor to make up the time within the schedule.
Your submittal has been assigned Cost Activity Code (CAC)/Enterprise Project Identification Number (EPID) A33010/L-2025-DOT-0007. Please reference this number and Docket No 71-3057 in any future correspondence associated with this request.
In accordance with Title 10 of the Code of Federal Regulations, Section 2.390 of the NRCs Agency Rules of Practice and Procedure, a copy of this e-mail will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records component of the NRCs ADAMS. ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
If you have any questions, please contact me.
Sincerely,
