Subject:
Acceptance of HI-STAR 100 Amd 14 Application for Review
Dear Ms. Manzione:
By letter dated August 1, 2025, (Agencywide Documents Access and Management System
[ADAMS] Accession No. ML25213A096, you submitted an application to the U.S. Nuclear Regulatory Commission (NRC) for amendment 14 of the Holtect HI-STAR 100 certificate of compliance (CoC) No. 9261. In your application, you requested the following changes:
Changes to the SAR to update maximum burnup in the MPC-32.
The purpose of this e-mail is to provide the results of the NRC staffs (the staff thereafter) acceptance review of this proposed request. 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 in sufficient detail to enable the staff to conduct 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 document attached to this e-mail includes staffs observations related to the materials and structural review. The staff included observations to allow you to start earlier on items containing the potential to be asked at a later date. Responses to observations are not required for staff to begin a detailed technical review. Observations are not the result of a detailed technical review and may be resolved once staff begins a detailed review.
The staff determined, based on historical data, thatthe technical review may require approximately 320 hours0.0037 days <br />0.0889 hours <br />5.291005e-4 weeks <br />1.2176e-4 months <br /> and 9 months. To support a more efficient process, the NRC is setting a goal of completing a review in less time and level of effort. The staff estimate for this review is approximately 225 hours0.0026 days <br />0.0625 hours <br />3.720238e-4 weeks <br />8.56125e-5 months <br /> and 7 months. The schedule includes the issuance of a request for additional information (RAI) in December 2025, if needed, and receiving your response by January 2026. The staff expects to complete the formal review and issue a certificate by April 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 Holtec International providing RAI responses 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 Holtec International 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) [001029 / L-2025-LLA-0119]. Please reference this number and Docket No. 71-9261 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,
-Chris Markley
