Senior Technical Nuclear Expert

Senior Technical Nuclear Expert

The Nuclear Company is the fastest growing startup in the nuclear and energy space creating a never before seen fleet‑scale approach to building nuclear reactors. Through its design‑once, build‑many approach and coalition building across communities, regulators, and financial stakeholders, The Nuclear Company is committed to delivering safe and reliable electricity at the lowest cost, while catalyzing the nuclear industry toward rapid development in America and globally.

The Senior Technical Nuclear Expert is a highly specialized technical leadership role responsible for providing deep nuclear engineering expertise across reactor systems, safety analysis, regulatory compliance, and nuclear facility design and operations. This position requires extensive knowledge of nuclear physics, reactor theory, safety systems, and NRC regulations to support TNC's fleet‑scale nuclear deployment. You will serve as a subject matter expert and technical authority on nuclear engineering matters, ensuring that all aspects of nuclear facility design, construction, and operations meet the highest standards of safety, quality, and regulatory compliance.

• Serve as subject matter expert on nuclear reactor systems, safety analysis, and nuclear engineering principles
• Provide advanced technical expertise on nuclear regulatory requirements including 10 CFR Part 50, 10 CFR Part 52, 10 CFR 50 Appendix B, and ASME NQA‑1 standards
• Lead technical reviews of design and construction processes associated with nuclear facilities
• Coordinate technical reviews of facility nuclear safety features
• Demonstrate deep knowledge of nuclear technology, reactor operations, and large‑scale engineering systems
• Provide technical guidance to engineering teams on nuclear safety systems and reactor design

• Perform safety evaluations to verify that nuclear systems meet requirements and will perform as needed to afford reasonable assurance of plant safety
• Analyze nuclear safety systems including reactor protection, emergency core cooling, and containment systems
• Conduct reactor physics analyses including criticality, neutron flux distribution, and fuel burnup calculations
• Evaluate reactor control systems and instrumentation for safety‑related functions
• Perform thermal‑hydraulic analysis of reactor core and cooling systems
• Assess accident scenarios and develop mitigation strategies
• Review passive and active safety systems for defense‑in‑depth capability

• Support NRC licensing activities including design certification, combined license (COL), and operating license applications
• Lead ITAAC (Inspections, Tests, Analyses, and Acceptance Criteria) development and closure to demonstrate compliance with design commitments
• Prepare and review safety analysis reports (SAR/FSAR) for NRC submission
• Support NRC inspections and respond to regulatory questions and requests for additional information (RAIs)
• Ensure compliance with 10 CFR 52.103(g) requirements for fuel load authorization
• Coordinate with NRC staff on technical issues and regulatory positions
• Track and implement regulatory guidance including Standard Review Plans (NUREG‑0800), Regulatory Guides, and industry standards

• Review and approve nuclear system designs for safety, reliability, and performance
• Evaluate equipment qualification for nuclear service including seismic, environmental, and radiation qualification
• Assess nuclear fuel design including enrichment, burnup, and reload strategies
• Review reactor core design including fuel assembly configuration and control rod patterns
• Evaluate radiation protection and shielding design for personnel safety
• Support nuclear island layout and arrangement optimisation
• Review nuclear‑grade component specifications and procurement requirements

• Ensure compliance with ASME NQA‑1 quality assurance requirements for nuclear facilities
• Review quality assurance programs for design, procurement, construction, and operations
• Support 10 CFR 50 Appendix B implementation and compliance…
