Job Description:

About

Our client is seeking to contract highly motivated and forward-thinking professionals who are interested in focusing on advanced nuclear reactor research and development and influencing change within the nuclear power landscape and bringing forward the critical production of medical isotopes.  In this role, you will support the nuclear methods team.

Responsibilities
•    Create formal documentation of benchmark evaluations, particularly in the area of criticality safety.
•    Evaluate sensitivities of benchmark model inputs to justify modeling effects.
•    Develop an automated test suite for the benchmark evaluations using Python.
•    Develop recommendations for margins of subcriticality (MoS) and upper subcritical limits (USLs) for specific storage and fuel transfer systems containing HALEU fuel.
•    Work within the nuclear methods team supporting the Natrium project on the development of applicable engineering and licensing media.

Key Qualifications and Skills

•    Advanced degree in Nuclear Engineering or equivalent and 4+ years of relevant experience preferred  
•    Experience in understanding and executing nuclear design/analysis methodologies, with a focus on criticality analyses using deterministic and/or stochastic simulation codes.
•    Excellent “under-the-hood” knowledge of the methods of reactor physics analysis.
•    Experience with some nuclear engineering software such as MCNP, Keno, or other industry-standard codes that are applied in radiation transport analyses in support of criticality safety work. MCNP is preferred.
•    Familiarity with ANSI/ANS criticality safety standards.
•    Familiarity with regulatory guidance on criticality safety controls.
•    Familiarity with the International Criticality Safety Benchmark Evaluation Project (ICSBEP) - https://www.oecd-nea.org/jcms/pl_24498/international-criticality-safety-benchmark-evaluation-project-icsbep is highly desirable.
•    Experience with analyses and methods using HALEU fuel and considerations for fast and moderated systems.
•    Strong programming skills in any language required, preferably in scientific computing; bonus points for Python, C++, and Fortran skills 
•    Proven ability to integrate and automate simulation tools 
•    Demonstrable capabilities with fundamental software development tools (e.g. IDEs, version control, profilers, debuggers, documentation builders, packaging tools) 
•    Experience interacting on nuclear methodology with the NRC under an ASME NQA-1 compliant QA environment preferred 
•    Good working knowledge of general numerical methods and applied mathematics (e.g. PDEs, numerical stability, statistics, numerical analysis, dynamics) 
•    Strong formal technical documentation skills required 
•    Ability to consistently deliver to an aggressive schedule 
•    Ability to seek out tasks and produce value aligned with team goals without waiting for next assignment 
•    Passion for and dedication to software best practices 
•    Willingness to openly give and accept professional criticism through code reviews and other venues 
•    Strong verbal communication skills desired 
•    The successful candidate will possess a high degree of trust and integrity, communicate openly and display respect, and a desire to foster teamwork
