Nuclear Safety Analysis Engineer

Join Our Team at Terrestrial Energy

Interested in helping us transform thermal and electric energy?

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

This opportunity is available in either our Charlotte, NC or Bryan, TX office.

Come join us at Terrestrial Energy, a US developer of advanced, Generation IV nuclear reactors. We are growing our workforce to develop and deploy our Integral Molten Salt Reactor (IMSR) small modular nuclear plant to provide cost-competitive, clean firm heat and power to industry.

The Company has recently completed a merger creating a publicly listed operating company (NASDAQ "IMSR"), to secure the capital resources for our next growth phase. With the current alignment of US Federal and State government, as well as industry interest in Small Modular Reactor (SMR) and advanced reactor technologies such as Terrestrial Energy's IMSR, there is today a unique and compelling opportunity to participate in the execution of the company's growth business plan.

The Company is building a team of high-performing business professionals and leaders in engineering, R&D, product management and business development areas at our Charlotte, North Carolina headquarters and future project sites. We are looking for talented individuals who can help build the organization, processes, and goal-orientated corporate culture to lead the company in our expansion. We are seeking people who:

• Have US market experience and perspectives bringing good judgement and innovative approaches to problem solving and business plan execution.
• Have demonstrated exceptional performance in past engineering projects.
• Offer exceptional leadership and team building capabilities.
• Have a deep understanding of the requirements for advanced reactor development.
• Can assist in the creation of the discipline and organized company structure, and contributed to a culture of excellence, necessary for the development and deployment of the Company's IMSR plant.
• Can thrive in a fast growing and opportunity business environment, and are capable of flexibility and adaptability at a time of organizational change.
• Have the specific skillset and experience for the following role:

Under the direction of Safety Manager, the Safety Analysis Engineer is critical to demonstrating the safety characteristics of Terrestrial Energy's IMSR technology and supporting regulatory licensing activities. The successful candidate is primarily responsible for performing comprehensive safety analyses, developing accident scenarios, and contributing to safety case documentation that demonstrates compliance with regulatory requirements and the inherent safety features of our advanced reactor design.

Other

Responsibilities Include:

• Perform deterministic and probabilistic safety analyses for the IMSR design
• Develop and analyze Design Basis Accidents (DBAs) and Beyond Design Basis Accidents (BDBAs)
• Conduct transient and accident analysis using thermal-hydraulic and neutronics codes
• Evaluate plant response to Postulated Initiating Events
• Assess the performance of Safety Systems and engineered safety features
• Analyze dose consequences and radiological release scenarios
• Perform sensitivity and uncertainty analyses

• Develop and validate computer models for safety analysis using industry-standard codes
• Build thermal-hydraulic models of reactor systems and components
• Perform single and coupled physics simulations
• Validate models against experimental data and benchmarks
• Document modeling assumptions, methodologies, and results

• Prepare safety analysis chapters for licensing documentation including Preliminary Safety Analysis Report (PSAR) and Final Safety Analysis Report (FSAR) for NRC/CNSC licensing
• Develop DOE-required safety analyses including Preliminary Documented Safety Analysis (PDSA) and Documented Safety Analysis (DSA) in accordance with DOE-STD-3009
• Highlight 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
• Define classification rules and terminology for safety SSCs, including application of the hierarchy of controls and Defense in Depth principles to ensure safety
• Perform analysis of most limiting potential dose consequences (e.g., unmitigated or Maximum Hypothetical Accident scenarios) to support Natural Phenomena Hazard (NPH) Natural Design Category (NDC) categorization
• Support validity assessment of selected safety document format and content, applicability of SSC classifications, and other graded approaches
• Support regulatory review processes and respond to technical questions from regulatory bodies (CNSC, NRC, DOE)
• Ensure analyses comply with applicable regulatory requirements and guidance
• Participate in regulatory meetings and technical discussions
• Support development of technical specifications and operational limits

• Prepare…
