Terrestrial Energy is a nuclear energy company that is developing a small modular reactor (SMR) technology. The company was founded in 2013 and is headquartered in Toronto, Canada. Terrestrial Energy's SMR technology is designed to be safer, more efficient, and more cost-effective than traditional nuclear reactors. The company's reactors use a molten salt fuel that is less prone to accidents and produces less waste than traditional nuclear fuel. Terrestrial Energy is currently working to obtain regulatory approval for its SMR technology.
