About this role
System One is a leader in delivering outsourced services and workforce solutions across North America. The Safety Analysis Engineer role involves performing deterministic nuclear safety analysis and transient/accident modeling to support U.S. NRC licensing submittals, developing system models, and collaborating across engineering teams.
Responsibilities:
- Perform deterministic safety analysis using RELAP5-3D code for the Natrium sodium fast reactor
- Analyze design basis accidents (DBAs) and licensing basis events (LBEs) to support reactor licensing with US NRC
- Model and integrate various plant systems within safety analysis computer codes
- Develop safety analysis reports, including the Final Safety Analysis Report (FSAR)
- Collaborate with cross-functional teams on core and reactor SSC requirements and licensing documentation
- Contribute to safety method development, code assessment, scaling analysis, and validation activities
- Maintain documentation of models and analysis results
- Conduct engineering reviews of analysis and design deliverables
- Assess plant transient benchmark tests and perform relevant benchmark calculations
- Support implementation of software capabilities for transient and accident analysis
Requirements:
- Extensive experience in nuclear safety analysis and reactor system modeling
- Proficiency with safety analysis software such as RELAP5, TRACE, TRAC, SAS4A/SASSYS-1, or similar
- Experience in transient and accident analysis for NRC submittals (e.g., Chapter 15 FSAR)
- Strong knowledge of nuclear systems thermal-hydraulics, reactor physics, and transient phenomena
- Familiarity with nuclear reactor instrumentation, control systems, and safety regulation compliance
- Degree: B.S. with 10+ years or M.S./Ph.D. with 5-7+ years of nuclear engineering or relevant field
- Demonstrated analytical, modeling, and reporting skills
- Experience working in multidisciplinary teams and under quality assurance programs (NQA-1)
- Strong software engineering skills in Python, Fortran, C++, or similar
