Job summary

Radiant is seeking a Senior Safety Analysis Engineer in El Segundo, CA to lead reactor safety analyses, evaluate normal and transient conditions, and inform design and regulatory decisions. You will own complex analyses across thermal-hydraulic modeling, source-term development, and radiological assessments, working with multiple engineering teams.

You should bring 5+ years of relevant experience, strong reactor physics knowledge, and experience with safety analysis codes.

Qualifications

• Bachelor's degree in nuclear or mechanical engineering or related technical discipline.
• 5+ years of reactor safety analysis or related experience.
• Experience with reactor safety analysis codes such as RELAP5-3D, TRACE, SAM, MELCOR or equivalent.
• 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 evaluating modeling assumptions, uncertainty, sensitivity and conservatism in analyses.
• Ability to own complex analytical projects and translate results into design requirements and safety conclusions.
• Strong written and verbal communication skills for reports and technical documentation.

Responsibilities

• Lead deterministic reactor safety analyses for operational occurrences, transients and postulated accidents.
• Develop system-level thermal-hydraulic and transient models to evaluate reactor response and safety margins.
• Perform source term and radiological consequence analyses including fuel performance and dose evaluations.
• Evaluate uncertainties in reactor physics, power distributions, fuel behavior, and models.
• Apply sensitivity studies and ranking methods to develop defensible analysis approaches.
• Collaborate with cross-functional teams to establish inputs, evaluate design options, and resolve safety challenges.
• Identify data gaps and validate predictions against experimental results.
• Develop and improve safety analysis methods, models and tools with verification and validation.
• Prepare calculation packages, safety analysis reports, and regulatory documentation.
• Work with regulatory and safety teams to support submissions and issue resolution.
