Canada's Terrestrial Energy Plans to Split IMSR Licensing to Accelerate Conventional Facility Construction and Financing

Recently, Canadian nuclear innovation company Terrestrial Energy announced that it has submitted a key topical report to the U.S. Nuclear Regulatory Commission (NRC). The company plans to license its Integral Molten Salt Reactor (IMSR) power plant as two separate parts—the nuclear facility and the Thermal and Electric Facility (TEF)—allowing the non-nuclear portion to be built and operated as a conventional industrial project before obtaining nuclear licensing. It is understood that the IMSR, as a Generation IV small modular reactor, uses molten salt as both fuel and coolant, and can directly supply heat to industrial facilities or be used for power generation. If the topical report is approved, the site-customizable TEF facilities will not be classified as nuclear facilities, thereby allowing developers to...
