IMSR®: How It Works

The IMSR® uses a fundamentally different reactor technology that leads to distinctive commercial advantages.

IMSR® is Versatile

IMSR®-generated heat is ideal for many industrial processes, not just for electricity production.

IMSR® Total System Cost

IMSR® power plants are cost-competitive with fossil fuels and renewables.

Sustainability: “Silver Buckshot or Bullet: Is a Future ‘Energy Mix’ Necessary?”

Article in the journal Sustainability posits that timely deployment of advanced nuclear like the IMSR®—”perfectly capable of providing all the energy humanity needs for centuries”—could be the silver bullet needed for achieving aggressive Paris climate targets.

Energies: Nuclear Power Learning and Deployment Rates; Disruption and Global Benefits Forgone

Peer-reviewed article in the journal Energies finds that had the rate of commercial nuclear deployment in the late-1960s to 1970s been maintained to the present day, nuclear power could now be around 10 percent of its current cost and could have substituted for 69,000 to 186,000 TWh of coal and gas generation—thereby avoiding up to 9.5 million deaths and 174 Gt CO2 emissions.

Terrestrial Energy’s Simon Irish at NY Times 2017 ClimateTECH

On November 30, 2017, Terrestrial Energy CEO Simon Irish explained why nuclear will be a clean energy solution to climate change at The New York Times’s 2017 ClimateTECH conference, with Lisa Friedman and Michael Shellenberger.

Rethinking Energy

Terrestrial Energy is rethinking energy. In this video, members of the Terrestrial Energy team explain the benefits of IMSR® technology, and explore the business itself.

Energy For Humanity: Decarbonizing Cities with Advanced Nuclear

Read the Energy For Humanity publication that cites Terrestrial Energy’s IMSR® as “one of the promising molten salt-based reactor designs currently in development.”

Renewable & Sustainable Energy Reviews: Feasibility of 100% Renewable Electricity Systems

Dr. Ben Heard and others publish in the journal Renewable & Sustainable Energy Reviews their analysis of the feasibility of 100% renewable-electricity systems and find that 24 academic studies published to-date provide no convincing evidence that basic feasibility criteria can be met.
