UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 MARCH 28, 2025 Mr. Simon Irish Chief Executive Officer Terrestrial Energy USA, Inc.
537 Steamboat Road Suite 200 Greenwich, CT 06830
SUBJECT:
REQUEST FOR WITHHOLDING PROPRIETARY INFORMATION FROM PUBLIC DISCLOSURE FOR TERRESTRIAL ENERGY USA, INCS.,
TECHNICAL REPORT: MODELING AND SIMULATION ACTIVITIES RELATED TO SOURCE TERM FOR IMSR DESIGN BASIS ACCIDENTS
Dear Mr. Irish:
On letter dated February 12, 2025 (Agencywide Documents Access and Management System (ADAMS) Package Accession No. ML25055A009), Terrestrial Energy USA, Inc., (TEUSA) submitted an affidavit executed by Mr. David Hill, to the U.S. Nuclear Regulatory Commission (NRC) staff requesting that the information contained in the following document be withheld from public disclosure pursuant to Title 10 of the Code of Federal Regulations (10 CFR),
Section 2.390, Public inspections, exemptions, requests for withholding:
Terrestrial Energy USA, Inc., Technical Report: Modeling and Simulation Activities Related to Source Term for IMSR Design Basis Accidents (Document
- TR250212)
The affidavit stated that the submitted information should be considered exempt from mandatory public disclosure for the reasons set forth in affidavit paragraphs (4)b and (4)c shown below:
[Contains] [i]nformation that, if used by a competitor, would reduce their expenditure of resources or improve their competitive position in the design, manufacture, shipment, installation, assurance of quality, or licensing of a similar product.
[Contains] [i]nformation that reveals aspects of past, present, or future TEUSA development plans and programs, resulting in potential products to TEUSA.
The NRC staff has reviewed the affidavit and the subject material in accordance with the requirements of 10 CFR 2.390 and based on the statements in the affidavit, has determined that the submitted information sought to be withheld contains proprietary commercial information and should be withheld from public disclosure.
Therefore, the Technical Report: Modeling and Simulation Activities Related to Source Term for IMSR Design Basis Accidents marked as proprietary will be withheld from public disclosure
pursuant to 10 CFR 2.390(b)(5) and Section 103(b) of the Atomic Energy Act of 1954, as amended.
Withholding from the public inspection will not affect the right, if any, of persons properly and directly concerned to inspect the documents. If the need arises, the NRC staff may send copies of the information to consultants working in this area. The NRC staff will ensure that the consultants have signed the appropriate agreements for handling proprietary information.
If the basis for withholding this information from public inspection should change in the future such that the information could then be made available for public inspection, TEUSA should promptly notify the NRC staff. TEUSA also should understand that the NRC staff may have cause to review this determination in the future if, for example, the scope of a Freedom of Information Act request includes TEUSA information.
In all review situations, if the NRC staff makes a determination adverse to the above, TEUSA will be notified in advance of any public disclosure.
If you have any questions regarding this matter, please contact Michelle Vega Rodriguez at 301-415-1170 or via email Michelle.VegaRodriguez@nrc.gov or Kevin Roche at 301-415-1554 or via email at Kevin.Roche@nrc.gov.
Sincerely,
/RA/
Kevin Roche, Project Manager Advanced Reactor Licensing Branch 2 Division of Advanced Reactors and Non-Power Production and Utilization Facilities Office of Nuclear Reactor Regulation Project No.: 99902076 cc: dcarleton@terrestrialusa.com
