Note: The job is a remote job and is open to candidates in USA. HukariAscendent is a women-owned small business providing engineering and technical support services for commercial nuclear power and Department of Energy nuclear activities. The Senior Safety Analysis Engineer will perform safety analyses for the Natrium Demonstration reactor, develop analytical models and methods, support reactor systems and licensing activities, and contribute to uncertainty quantification, benchmarking, and software framework implementation.
Responsibilities
- Develop system models and perform safety analysis of Anticipated Operational Occurrence (AOO), Design Basis Event (DBE), and Design Basis Accident (DBA) scenarios for the Natrium Demonstration reactor
- Collaborate with cross-functional teams to establish core and reactor SSC functional, performance, safety, and quality requirements, and 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 safety method development, including code assessment, scaling analysis, and code verification and validation activities
- Develop and maintain documentation of model development and analysis results
- Perform engineering reviews of other engineering analyses and design deliverables, such as ASME design transients
- Assess plant transient benchmark tests, identify tests relevant to the Natrium reactor, and perform benchmark calculations
- Contribute to the software framework implementation of capabilities required for transient and accident analysis
Skills
- Extensive experience in nuclear safety analysis and 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 of 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 safety analysis computer codes
- Familiarity with nuclear design, regulatory requirements, and risk-informed performance-based technology guidance for Non-Light Water Reactors is required
- Experience with SFR safety analysis or methods is highly desirable; experience with other reactor designs, such as Light Water Reactors (LWRs), will also be considered
- Demonstrated strong quantitative, analytical, modeling, and reporting skills
- Understanding of NQA-1 requirements associated with analysis and software management, and experience working under a quality assurance program
- Experience working in multi-disciplinary engineering teams to address engineering challenges
- Strong software engineering skills in any language, such as Python, Fortran, or C++, are a plus
- B.S., M.S., or Ph.D. in Nuclear Engineering or other relevant engineering discipline, with a minimum of 5 years' experience in the nuclear field
- High degree of trust and integrity, with strong communication skills and a demonstrated ability to foster teamwork
- Familiarity with EMDAP and Regulatory Guide 1.203 is preferred
