Nuclear Safety Analysis Manager

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 $ to $ 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 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:

• Lead, mentor, and develop a team of Safety Analysis Engineers, Safety Analysts, and Specialists
• Establish team priorities, allocate resources, and manage workload across multiple projects
• Conduct performance evaluations and support professional development of team members
• Foster a culture of technical excellence, safety consciousness, and continuous improvement
• Recruit and build a high‑performing safety analysis team
• Establish and maintain safety analysis standards, procedures, and best practices
• Manage departmental budget and resource planning

• Oversee deterministic and probabilistic safety analyses for the IMSR design
• Direct the development and analysis of Design Basis Accidents (DBAs) and Beyond Design Basis Accidents (BDBAs)
• Ensure comprehensive transient and accident analyses using thermal‑hydraulic and neutronics codes
• Oversee evaluation of plant response to postulated initiating events
• Manage assessment of safety systems and engineered safety features performance
• Direct dose consequence and radiological release scenario analyses
• Oversee sensitivity and uncertainty analyses programs
• Ensure integration of safety analyses across multiple engineering project teams

• Prepare safety analysis chapters for licensing documentation including Preliminary Safety Analysis Report (PSAR) and Final Safety Analysis Report (FSAR) for NRC/CNSC licensing
• Oversee development of DOE‑required safety analyses including Preliminary Documented Safety Analysis (PDSA) and Documented Safety Analysis (DSA) in accordance with DOE‑STD‑3009
• Direct development of key safety decisions including target performance of structures, systems, and components (SSCs), safety system responses to normal and off‑normal operations, and facility security considerations
• Establish classification rules and terminology for safety SSCs, including application of the hierarchy of controls and Defense in Depth principles to ensure safety
• Oversee analysis of most limiting potential dose consequences (e.g., unmitigated or Maximum Hypothetical Accident scenarios) to…
