IMSR®: Transformative Clean Energy Technology

To meet the increasing energy demands of global prosperity, while protecting the environment and the air in our cities that we breathe, we need a game changer.

Terrestrial Energy’s IMSR® Advanced Modular Reactor is that technology.
small and advanced modular reactors technology - advance nuclear reactor design by Terrestrial Energy

Terrestrial Energy is developing revolutionary — not simply evolutionary — nuclear technology. The IMSR® uses completely different nuclear technology for its Advanced Modular Reactor — molten salt fuel instead of conventional solid fuel. With this proven approach, IMSR® Generation IV nuclear power plants are more affordable, cost competitive, and versatile than conventional nuclear power plants.

IMSR® technology can be brought to market quickly. IMSR® power plants can be built in four years and produce electricity or industrial heat at prices competitive with fossil fuels, while emitting no greenhouse gases.

The first IMSR® power plants are expected to come online in the 2020s.

IMSR® technology is today’s clean energy game changer.

Oakville, Ontario and New York – December 4, 2019 – The Canadian Nuclear Safety Commission (CNSC) and the United States Nuclear Regulatory Commission (NRC) have selected Terrestrial Energy’s Integral Molten Salt Reactor (IMSR®) for the first joint technical review of an advanced, non-light water nuclear reactor technology.

OAKVILLE, ON – November 26, 2019 – Frazer-Nash Consultancy (Frazer-Nash) and Terrestrial Energy have signed a contract for engineering services related to the fabrication of the graphite moderator, a key component in Terrestrial Energy’s Integral Molten Salt Reactor (IMSR®), a Generation IV advanced nuclear power plant.

"Nuclear power has a lot going for it. It’s carbon-free, can produce huge amounts of power from relatively small amounts of fuel, and once plants are built, they’re heap to run," according this new article in Singularity Hub.
Think tank Third Way has updated its Advanced Nuclear Map for 2019, which charts the progress of advanced nuclear innovation projects across the United States and Canada and includes Terrestrial Energy. "To mitigate the most serious threats posed by climate change, we must get to net-zero carbon emissions as fast, and fairly as possible," according to Third Way, It adds that one of the most promising ways to get there is with advanced nuclear technologies.
