Project Manager – Engineering

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 a 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 ideally suited for distributed generation on a large‑scale of electricity and heat across many energy‑intensive industries, including but not limited to petrochemical and chemical plants, and data centers. The IMSR plant provides a near 50 % improvement in efficiency of electric power generation compared to Light Water Reactor nuclear plants. Its industrial cogeneration capability delivers industrial competitiveness, security of energy, and zero‑emissions industrial production. The IMSR plants use existing industrial materials, components, and fuels to support near‑term deployment, setting the stage for a transformation and rapid global decarbonization of the primary energy system.
