Terrestrial Energy

This is next-generation fission technology: powerful, affordable, carbon-free energy.

IMSR® Technology

Integral Molten Salt Reactor®: Carbon-free, low-cost, high-impact. Flexible and resilient.

IMSR cogeneration plants capture the full advantages of molten salt fission technology and the superiority of a molten salt as a reactor coolant. They are safe, reliable, carbon-free and low-cost. They produce thermal energy (heat) at high temperature for the industrial sector. IMSR plants offer a game-changing 50% efficiency improvement in electricity generation. With many industrial uses and compelling economic potential, IMSR plants are a powerful tool to drive economic growth, support energy security, and achieve net-zero quickly. They are the much-needed alternative to burning fossil fuels for industrial heat.

Commercial Advantages

Nuclear fission technology and plant design choices in the IMSR cogeneration plant deliver compelling cost-competitive commercial advantages over fossil fuel combustion and conventional nuclear plants.

Many Industrial Uses

IMSR cogeneration plants produce high-temperature heat or power or a mix of both. They can serve the electric grid and industries alike. They can load-follow seamlessly as the clean power partner for variable renewables.

Path to Market

Terrestrial Energy’s regulatory and engineering programs target an international role-out of IMSR cogeneration plants starting 2030. We have a track record of meeting our milestones.

How it Works

The IMSR cogeneration plant blends proven molten salt technology with
