Safeguards & Non-Proliferation Engineer

Our client's MCFR project seeks a motivated engineer to develop tools for inventory calculations and uncertainty analysis for material accounting. Your job will include identifying and quantifying new or unanticipated sources of uncertainty; developing computational tools and processes for propagating uncertainty across complex, dynamic systems; and conducting sensitivity analyses to prioritize efforts to reduce uncertainty.

Responsibilities:

Create methodologies and tools for calculating special nuclear material inventories and uncertainties in MCFR fuel salts and waste products under varied deployment, operational, and process conditions. Develop approaches to identify, quantify, and propagate uncertainty from diverse sources of data and computational tools Develop statistical methodologies for detection of inventory losses or anomalies Conduct sensitivity analysis to prioritize sources of uncertainty and inform the selection, design, and testing of instrumentation used for material accounting across reactor systems Collaborate with cross-functional, multi-disciplinary engineering teams to develop material accounting and safeguards approaches for MCFR plants and address technical challenges Facilitate licensing activities for MCFR technology Participate in training programs and workshops to enhance understanding of safeguards and material accounting in domestic and international contexts Publish and present results for peer review to advance broad public acceptance Key Qualifications and Skills:

B.S. (+4-6 years relevant experience), M.S. (+2-3 years relevant experience), or Ph.D (+1-2 years relevant experience) in mathematics, data science, engineering, physical sciences, or a related technical field, is required. Good working knowledge of nuclear and/or general numerical methods, e.g., partial differential equations, dynamics, deterministic and stochastic particle transport, isotopic depletion, perturbation theory, nuclear data, kinetics. Experience in uncertainty analysis and quantification for complex systems is required. Experience with nuclear engineering software such as ARMI, MCNP, OpenMC, Serpent, SCALE, DIF3D, Attila, GRIFFIN, PROTEUS, MC2, PARTISN, PARCS, APA, CASMO, DRAGON, etc. is highly desired. Strong programming skills in any language is required, with a strong preference for Python, C++, Git, and Github experience. Ability to work in a rapidly evolving and iterative design environment. Excellent analytical, problem-solving, and communication skills, with the ability to convey complex technical information effectively to diverse audiences. Proven ability to work collaboratively in cross-functional teams, prioritize tasks, and manage multiple projects simultaneously. The successful candidate will possess a high degree of trust and integrity, communicate openly and display respect and a desire to foster teamwork. Actual position starting level and title will be determined based on assessment of qualifications. Bonus Qualifications and Skills:

Familiarity with domestic and international safeguards, including prior experience working on material control and accounting (MC&A) programs for advanced reactors or bulk material handling fuel cycle facilities Experience with advanced and/or molten salt reactor core design Ability and professionalism to work within published regulatory guidelines for nuclear reactor design, including experience working under an NQA-1 or equivalent quality program
