R&D Physics Scientist

Interested in helping us transform thermal and electric energy

Become a part of the leading Generation-IV nuclear plant development team.

Terrestrial Energy is developing for near-term commercial operation a zero-emissions cogeneration plant for global industry using its proprietary Integral Molten Salt Reactor (IMSR) fission technology in an innovative small and modular plant design. The IMSR is a non-Light Water Reactor of the Generation IV class that operates at the high temperature required for broad industrial relevance with transformative economic potential. The IMSR plant is capable of grid-based electric power generation and industrial cogeneration in many energy-intensive industries including petrochemical and chemical synthesis for hydrogen and ammonia production. The IMSR plant offers a near 50 percent improvement in efficiency of electric power generation compared to Light Water Reactor nuclear plants. Its industrial cogeneration capability delivers to todays markets industrial competitiveness security of energy and zero-emissions industrial production. The IMSR plants use of existing industrial materials components and fuels supports its near-term deployment setting the stage for a rapid global decarbonization of the primary energy system.
