Advanced Reactor Nuclear Engineer

Idaho National Laboratory is hiring an Advanced Reactor neutronics, thermal‑hydraulics, thermo‑mechanical, or structures analyst to work in our Materials and Fuels Complex Reactor Engineering group. This position is located at our Materials and Fuels Complex. Our team works a 9x80 schedule with every other Friday off.

INL is recognized as the lead national laboratory for DOE-NE, providing much of the nuclear research, development, and demonstration capability needed to move nuclear innovation forward to deployment. MFC hosts a unique combination of personnel, facilities, and infrastructure for the deployment of advanced nuclear reactors.

As a Reactor Engineering Analyst, you will analyze neutronics, thermal, or mechanical behavior of advanced reactors demonstrations  will be responsible for contributing delivery of confirmatory analyses to support design and product acceptance of new nuclear reactor systems focus on micro‑reactors, assisting in startup physics testing of advanced reactor, and supporting existing reactors.

• Supports, coordinates and performs confirmatory calculations and startup planning in area of technical expertise (e.g. reactor physics, thermal hydraulics, thermo‑mechanical analysis) to support development of facility and reactor specific safety basis supporting analyses.
• Work includes planning, scheduling, and tracking of reactor analyses and planning for startup testing and verification activities to validate analytical work and ensure safety.
• Verify compliance of advanced reactor designs according to industry codes, such as ASME Boiler Pressure Vessel Code. Decompose project goals into defined and controlled design requirements.
• Responsible for providing support to project and planning activities related to new reactor design and acceptance, talking to design and nuclear safety organizations, working with external reactor designers and DOE ( HQ), and contributing organizations (e.g. structural analysis, criticality safety, radiation protection, etc.).
• Participate in the evaluation and resolution of complex engineering problems. Contribute to technical decisions based on sound engineering practices and in accordance with Laboratory policies and procedures.
• Apply advanced nuclear engineering design principles, theories, and concepts.
• Use best practices in design methodologies to develop and validate designs.
• Document designs to ensure conformance with requirements and standards.
• Establish testing, inspection, and quality requirements.
• Ensure fabrication, construction, assembly, and procurement align with design specifications.
• Defend analytical methods and results in reviews.
• Support project/program interactions with sponsors, operations, and engineering organizations.
• Develop and improve physics‑based mathematical models and analysis methods.
• Prepare reports and peer‑reviewed publications.
• Participate in professional development activities.
• Other duties as assigned.
