Overview Interested in helping us transform thermal and electric energy? Become a part of the leading Generation-IV nuclear plant development team. For this role in Oakville, Ontario, the salary range for this position is CAD $140,000.00 to $185,000.00 per annum. The actual wage offered will be determined based on factors such as education, experience, knowledge, skills, abilities, applicable market data for the work location, and internal equity considerations. 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 Generation IV non-Light Water Reactor that operates at high temperature for broad industrial relevance with transformative economic potential. The IMSR plant can generate grid-based electric power and provide industrial cogeneration for energy-intensive industries, including 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 supports industrial competitiveness, energy security, and zero-emissions production. Terrestrial Energy is building toward rapid global deployment and is seeking talented people who will contribute to the following role. Role focus: leading and growing a safety analysis organization to support safety analysis and licensing activities for the IMSR technology.
