Senior Safety Analysis Engineer

The Senior Safety Analysis Engineer is primarily responsible for performing safety analyses of the Natrium Demonstration reactor, and support design transients analysis, Structures, Systems and Components (SSC) classification, development of analytical models and methods, as well as uncertainty quantification and sensitivity calculation.

Job Highlights:

The job involves performing deterministic safety analysis using the RELAP5-3D code for the Natrium sodium fast reactor. The role includes analyzing the design basis accidents (DBAs) and licensing basis events (LBEs) to support the reactor licensing with US NRC. Additionally, this position emphasizes modeling and integration of various plant systems in the safety analysis computer code.

• Deterministic safety analysis
• Skills of using and/or modeling in RELAP5-3D
• Develop safety analysis report, such as the Final Safety Analysis Report (FSAR)
• Good understanding of the nuclear power plant systems and components

Responsibilities:

• Develop system models and perform safety analysis of Anticipated Operational Occurrence (AOO), Design Basis Event (DBE), and Design Basis Accident (DBA) for the Natrium Demonstration reactor.
• Collaborate with cross-functional teams to establish core and reactor SSC functional, performance, safety, and quality requirements as well as support the overall design.
• Collaborate with cross-functional teams to integrate NEI 18-04 Licensing Basis Event (LBE) analyses and findings into licensing documentation and project design activities.
• Contribute to the safety method development, such as code assessment, scaling analysis, code verification and validation activities, etc.
• Develop and maintain documentation of model development and analysis results.
• Perform engineering reviews of other engineering analysis and design deliverables, such as ASME design transients
• Assess plant transient benchmark tests, identify applicable tests relevant to the Natrium reactor and perform benchmark calculations.
• Contribute to the client’s software framework implementation of capabilities required for transient and accident analysis.

Key Qualifications and Skills:

• Extensive experience in nuclear safety analysis, nuclear reactor system modeling.
• Significant experience with safety analysis software such as RELAP5, TRACE, TRAC, SAS4A/SASSYS-1, or other nuclear system analysis software.
• Experience in transient and accident analysis for submittals to NRC, such as Chapter 15 in the Final Safety Analysis Report (FSAR), is highly desired.
• Knowledgeable of nuclear systems thermal-hydraulic fundamentals as well as reactor dynamics and transient phenomena.
• Knowledgeable of nuclear reactor core physics such as neutron transport theory and reactivity feedback.
• Knowledgeable of nuclear reactor instrumentation and control systems, and related modeling approaches in the safety analysis computer code.
• Familiarity with nuclear design, regulatory requirements, and risk-informed performance-based technology guidance for Non-Light Water Reactors is required.
• Familiarity with EMDAP and Regulatory Guide 1.203 is preferred.
• Experience with SFR safety analysis or methods is highly desirable. Experience with other reactor designs, such as Light Water Reactors (LWRs), can be considered when differentiating candidates.
• Demonstrated strong quantitative, analytical, modeling and reporting skills.
• Understanding NQA-1 requirements associated with analysis and software management as well as experience working under a quality assurance program.
• Experience in working in multi-disciplinary engineering teams to address engineering challenges.
• Strong software engineering skills in any language, such as Python, Fortran, or C++, is a plus.
• B.S. with 10 years of experience, M.S. or Ph.D. in nuclear engineering, or other relevant engineering degree, with a minimum of 5-7 years’ experience in the nuclear field.
• The successful candidate will possess a high degree of trust and integrity, communicate openly and display respect and a desire to foster teamwork.
