Terrestrial Energy
Overview
Interested in helping us transform thermal and electric energy? Become a part of the leading Generation-IV nuclear plant development team. This is available in either our Charlotte NC or Bryan TX office.
Company Background 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. Over the last 5 years, the Company has recognized the exceptional and unmatched opportunities in US markets created by the policies of the US Federal and States’ governments, and by the actions of the US industrial private sector, including its world leading IT sector developing AI commercial product. The Company recognizes that its path to business success and likely sole path to success, is to wholly align with the US market as a US company, and effect all the organizational changes necessary to achieve this alignment. In pursuit of this objective, Terrestrial Energy initiated a transaction to legally redomicile the business to the US in 2023, which it completed in April 2024, with 100% shareholder support. This transaction was the first step in its US domiciliation strategy. The Company is currently completing a transaction to secure a US exchange (NASDAQ) public stock listing, which is expected to secure the capital resources necessary to complete its US domiciliation as well as execute on its business plan focused on the US market.
Team Building The Company is focused on building a team of business professionals and leaders in the engineering, R&D, product management and business development areas out of our Charlotte, North Carolina location. These key resources will help build the organization structure and processes in Charlotte NC, which will be the cornerstone to add talented people to the US team, each of whom:
Will offer US market experience and perspectives bringing innovative approaches to problem solving and business plan execution.
Has demonstrated exceptional results in past engineering projects.
Will offer exceptional leadership and team building capabilities.
Has a deep understanding of the requirements for advanced reactor development.
Will assist in the creation of the organization architecture and structures based in Charlotte and necessary for the successful design development of the Company IMSR plant.
Is capable of flexibility and adaptability at a time of organizational change.
Has skillset and experience that relate to the following role.
Safety Analysis Engineer – Responsibilities The Safety Analysis Engineer, under the direction of Safety Manager, 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
Modeling and Simulation
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
Regulatory Support
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
Documentation and Reporting
Prepare detailed technical reports documenting analysis methodologies, assumptions, and results
Create clear visualizations and presentations of analysis results
Maintain comprehensive documentation of safety analysis activities
Contribute to technical publications and conference papers
Develop and maintain analysis procedures and quality assurance documentation
Collaboration
Work closely with Physics, Thermal-Hydraulics, Systems Engineering, and Design Teams
Interface with external partners including national laboratories and consultants
Participate in design reviews and technical meetings
Support integrated safety assessments across multiple disciplines
Contribute to continuous improvement of safety analysis methods
Requirements Education
