Job Title: Nuclear Methods Engineer

Type: Contract (yearlong) typically extends on a yearly basis

Compensation: $56 - $95 hourly

Contractor Work Model: Fully Remote

Paid holidays | PTO

System One is seeking a highly motivated Nuclear Methods Engineer to support nuclear analysis methods for design and licensing of a demonstration MCFR reactor, beginning with development and implementation of nuclear analysis capabilities and evolving toward software qualification under and NQA-1 environment. You’ll collaborate with the modeling and simulation lead, MCFR plant design engineers, and the nuclear validation lead in a high-performing, multi-disciplinary environment to automate and then validate these nuclear methodologies.

Tasks

+ Development of neutronics methods to perform neutronics analysis of a fast spectrum molten salt reactor.

+ Implementation nuclear analysis methodologies via Python software

+ Core design and analysis activities of advanced nuclear reactors, including calculation and optimization of fuel management strategies, reactivity coefficients, control rod worth and shutdown margin, and radiation damage.

+ Software configuration management through code review, software documentation, software testing, and continuous integration.

+ Sensitivity studies to understand the effects and validity of various modeling assumptions, including delayed neutron fractions, evaluated nuclear data sets, geometry representation, etc.

+ Validation of neutronics analysis by leveraging benchmark models of historical reactors, reactor experiments, and critical assemblies.

Key Qualifications and Skills

+ Bachelors degree in Science or Engineering and 6 – 10 years of relevant experience. Experience Level may be partially substituted for advanced degree depending on position relevance.

+ Experience in understanding and executing nuclear design/analysis methodologies, including criticality, flux/power distributions, fuel cycle analyses, reactivity coefficients, shielding, activation, control rod worth, detector response, and uncertainty analysis, ideally with a focus on fast-neutron reactors.

+ Experience with radiation transport software is required. Experience with MCNP, OpenMC, Attila, is preferred. Experience with ARMI, Serpent, SCALE, DIF3D, MC2, PARTISN, MOOSE, PARCS, APA, CASMO, DRAGON, is also relevant.

+ Programming experience in any language required, preferably in scientific computing; bonus points for Python skills.

+ Working knowledge of fundamental software development tools (e.g. IDEs, version control, profilers, debuggers, documentation builders, packaging tools).

+ Experience interacting on nuclear methodology with the DOE and/or NRC under an ASME NQA-1 compliant QA environment is preferred.

+ Strong communication skills desired.

+ The service provider will possess a high degree of trust and integrity, communicate openly and display respect, and a desire to foster teamwork.
