LAYIQ - Senior Safety Analysis Engineer at Radiant Industries

Lead deterministic reactor safety analyses covering anticipated operational occurrences, transients, and postulated accident scenarios.
Develop and apply system-level thermal-hydraulic and transient models to evaluate reactor response, operating limits, and safety margins.
Perform source term and radiological consequence analyses, including fuel performance, fission product release and transport, and dose evaluations.
Evaluate uncertainties in reactor physics, power distributions, fuel behavior, and thermal-hydraulic models and their impact on safety conclusions.
Apply sensitivity studies, bounding assumptions, and phenomena-ranking methods to develop technically defensible analysis approaches.
Collaborate with nuclear, mechanical, thermal, materials, and controls teams to establish analysis inputs, evaluate design alternatives, and resolve safety-related technical challenges.
Partner with testing and materials teams to identify data gaps, establish validation requirements, and correlate analytical predictions with experimental results.
Develop and improve safety analysis methods, models, and tools, including verification and validation, configuration control, and uncertainty quantification.
Prepare and technically review calculation packages, safety analysis reports, and regulatory documentation supporting reactor design and licensing activities.
Work with regulatory and safety teams to establish safety requirements, support technical submissions, and resolve technical issues through closure.
Required Qualifications & Skills
Bachelor's degree in nuclear engineering, mechanical engineering, or a related technical discipline from an accredited institution.
5+ years of relevant experience in reactor safety analysis, thermal-hydraulics, nuclear systems modeling, or related engineering disciplines.
Experience developing and applying reactor systems or safety analysis codes such as RELAP5-3D, TRACE, SAM, MELCOR, or equivalent tools.
Strong understanding of reactor thermal-hydraulics, transient behavior, heat transfer, and deterministic safety analysis.
Knowledge of reactor physics, fuel performance, fission product behavior, and radiological safety principles.
Experience developing or evaluating source terms, radiological consequences, or other safety-related performance calculations.
Experience evaluating modeling assumptions, uncertainty, sensitivity, and conservatism in engineering analyses.
Demonstrated ability to independently own complex analytical projects and translate results into design requirements, safety conclusions, and technical documentation.
Strong written and verbal communication skills, including experience preparing rigorous calculation packages, technical reports, or safety-related engineering documentation.
