The Nuclear Regulatory Commission and Canadian Nuclear Safety Commission have completed a first joint technical review of Terrestrial Energy’s Integral Molten Salt Reactor, the company announced earlier this week.

The IMSR was selected in December 2019 to be the first advanced non–light water nuclear reactor technology to be studied under an August 2019 NRC/CNSC memorandum of cooperation aimed at enhancing regulatory effectiveness through collaborative work on technical reviews of advanced reactor and small modular reactor technologies.
