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 today’s markets industrial competitiveness, security of energy, and zero-emissions industrial production. The IMSR plant’s 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. To execute this plan, we are now looking to add talented people to the team, each of whom will: improve our team by adding diverse perspectives and innovative ways of problem solving have demonstrated exceptional results in engineering projects be a team player with the ability to collaborate closely and interact with other groups be flexible and adaptable to change have skillset and experience that relate to the following role:

The Senior Mechanical Engineer (Stress Analysis), under the direction of the Mechanical Engineering Manager, is primarily responsible for mechanical design analysis of reactor systems and components (using Finite Element Analysis (FEA) and analytical methods) through the Detailed Engineering phase. Responsibilities include:

Prepare calculations and reports for reactor components (such as pressure vessels, supports, graphite core components, and other in-core components), including fatigue, creep, dynamic and static, linear and non-linear analysis as needed. Assess structural integrity of proposed designs and provide feedback to optimize mechanical design and performance using analysis results. Participate in design reviews and review design documents and calculations Communicate and work with various technical disciplines to understand interfacing system design(s) and interfacing requirements as well as system/component loading Conduct presentations to interdisciplinary teams and external parties Interface with external vendors, experts and design agencies Mentor junior and intermediate level engineers and analysts
