Terrestrial Energy aims to build and commission with a power utility the first its walkaway safe molten salt modular reactor design in the late 2020s.
An IMSR® power plant generates 400 megawatts of thermal energy (190 MW electric) with a thermal-spectrum, graphite-moderated, molten-fluoride-salt reactor system. It uses standard nuclear fuel – standard-assay low-enriched uranium (less than 5 percent 235U) fuel. It incorporates many aspects of Molten Salt Reactor operation researched, demonstrated and proven by test reactors at the Oak Ridge National Laboratory.
Terrestrial Energy's Integral Molten Salt Reactor (IMSR) has entered the second phase of a vendor design review by the Canadian Nuclear Safety Commission (CNSC). The design was the first advanced reactor to complete the first phase of the CNSC's regulatory pre-licensing review.
