US-based Terrestrial Energy Proposes Phased Construction Model to Accelerate Deployment of 390 MW Integrated Molten Salt Reactor
Fourth-generation advanced nuclear developer Terrestrial Energy has recently formally submitted to the U.S. Nuclear Regulatory Commission (NRC) a topical report for the Thermal and Electric Facility (TEF) of its Integrated Molten Salt Reactor (IMSR) project. The document proposes a dual-track regulatory review model aimed at allowing key non-nuclear power components of the plant to proceed with construction and enter commercial operation before a full nuclear facility license is obtained. If this regulatory approach is approved by federal regulators, it will effectively break through the economic and approval obstacles that have long constrained the development of the nuclear power industry. In traditional nuclear power projects, because regulatory...

Terrestrial Energy Submits Graphite Topical Report to U.S. Nuclear Regulatory Commission, Advancing Integrated Molten Salt Reactor Licensing Process
Terrestrial Energy, a leading company in fourth-generation molten salt reactor technology, announced on September 10 that it has submitted the Graphite Topical Report to the U.S. Nuclear Regulatory Commission (NRC). The submission of this report is intended to establish a solid regulatory certification basis for the application of nuclear-grade graphite—a core component of the IMSR core unit—in commercial power plants, marking an important step in the company's commercialization process. The IMSR reactor is a graphite-moderated molten salt reactor. Although graphite has a relatively long history of application in the nuclear power field, regulators require independent performance verification for each specific reactor design to ensure safety and reliability.
