Original job description

Idaho National Laboratory is hiring a Advanced Reactor System Code Analyst to work in our MFC Reactor Engineering department. Our team works a 9x80 schedule located in Idaho Falls, with every other Friday off. As a Advanced Reactor System Code Analyst, you will characterize the thermal, reactor kinetic, and overall system behavior of advanced reactor structures, systems, and components under normal operating conditions, planned transients, reactivity insertion events, natural phenomena hazards, and accident conditions. You will develop and evaluate predictive models that support nuclear safety analyses, fundamental safety functions, and advanced reactor demonstration activities at INL.

Responsibilities Include:

Analyze advanced reactor core behavior and overall system response under normal operating conditions, planned transients, natural phenomena hazards, reactivity insertion events, and accident conditions.
Develop accurate and appropriately conservative analytical models to verify that advanced reactor designs satisfy applicable acceptance criteria, safety requirements, and design requirements.
Apply the Evaluation Model Development and Assessment Process, including defining model requirements, developing models that meet those requirements, validating model performance, and demonstrating that evaluation models are adequate for their intended applications.
Support, coordinate, and perform confirmatory calculations and startup planning in the areas of thermal-hydraulic, reactor kinetic, and system analysis to support facility-specific and reactor-specific safety basis analyses.
Plan, schedule, and track reactor analyses, startup testing, and verification activities to validate analytical work, confirm system performance, and support safe reactor operations.
Develop and apply reactor system models using analytical tools and system codes such as RELAP5-3D, SAM, GOTHIC, TRACE, MOOSE-based applications, or comparable analysis software.
Provide technical support for project planning activities related to new reactor design, evaluation, acceptance, and startup.
Coordinate with reactor design, nuclear safety, structural analysis, criticality safety, radiation protection, and other contributing organizations. Work with external reactor designers and U.S. Department of Energy organizations, including DOE Idaho Operations Office and DOE Headquarters.
Document analytical methods, assumptions, model inputs, results, uncertainties, and conclusions in accordance with applicable quality assurance requirements and Laboratory policies and procedures.
Participate in the evaluation and resolution of complex engineering problems. Contribute to technical decisions using sound engineering judgment, validated analytical methods, and established Laboratory procedures.

Minimum Requirements:

Level 3: Bachelor’s degree in mechanical engineering, or other related technical discipline plus 5 years relevant experience, or Advanced Degree in Mechanical Engineering, or other related degree with 2 years relevant experience or a closely related field from a program accredited by ABET.
Level 4: Bachelor’s degree in mechanical engineering, or other related technical discipline plus 9 years relevant experience, or Advanced Degree in Mechanical Engineering, or other related degree with 6+ years relevant experience or a closely related field from a program accredited by ABET.
This position requires the ability to obtain and maintain a Department of Energy "Q" clearance, which requires US Citizenship.
