SUBJECT:
U.S. NUCLEAR REGULATORY COMMISSION OBSERVATIONS ON TERRESTRIAL ENERGY USA, INCS INTEGRAL MOLTEN SALT REACTOR CORE-UNIT DEFINITION WHITE PAPER (EPID NO.: L-2021-LRO-0052)
Dear Mr. Irish:
By letter dated May 6, 2022 (Agencywide Documents Access and Management System (ADAMS) Package Accession No. ML22138A340), Terrestrial Energy USA, Inc. (TEUSA),
submitted a white paper titled IMSR Core-unit Definition - Applicable Structures, Systems and Components, for the U.S. Nuclear Regulatory Commission (NRC) staffs review. The white paper provides details related to the design and operation of important structures, systems, and components (SSCs) that make up the Integral Molten Salt Reactor (IMSR) power plant.
TEUSA requested the NRC staff to review the white paper and provide written feedback and questions on areas where the white paper does not provide sufficient detail for the NRC staff to have a clear understanding of the design basis and operation of the IMSR power plant, and more specifically on those SSCs that are important to the safe operation of the IMSR Core-unit.
The NRC staffs observations are provided in Enclosure 1 (Proprietary) and Enclosure 2 (Non-Proprietary) of this document.
If you have any questions regarding this matter, please contact Adrian Muniz at (301) 415-4093 or via e-mail at Adrian.Muniz@nrc.gov.
Sincerely, Michael Wentzel, Chief Advanced Reactor Licensing Branch 2 Division of Advanced Reactors and Non-Power Production and Utilization Facilities Office of Nuclear Reactor Regulation Project No.: 99902076
