Talascend is currently seeking a Nuclear Methods Engineer for a contrat opportunity located in Bellevue, WA.

PRIMARY RESPONSIBILITIES:

In this role, you will support the nuclear methods team:
Create formal documentation of nuclear methods software requirements, design, implementation, and testing, primarily in support of licensing Natrium reactors.
Perform commercial grade dedication of third-party reactor physics tools and data.
Design and execute sensitivity studies to understand the effects and validity of various modeling assumptions, including meshing, physics coupling, transport options, cross section preparation, fission product models, spatial kinetics, etc., and adjust methods as necessary.
Apply methods to assess the propagation of uncertainty and their effect on safety margins.
Build and evaluate benchmark models of historical reactors, reactor experiments, and critical assemblies.
Train and support reactor designers and developers in the use of the design software suite.

POSITION REQUIREMENTS:

Advanced degree in Nuclear Engineering or equivalent and 2+ years of relevant experience preferred.
Nuclear engineering skills.
Fast reactor physics and design intuition.
Experience in understanding and executing nuclear design/analysis methodologies, including criticality, flux/power distributions, fuel management optimization, reactivity coefficients, shielding, activation, control rod worth, detector response, and uncertainty analysis, ideally with a focus on fast-neutron reactors.
Experience with some nuclear engineering software such as DIF3D, MC2, PARTISN, MCNP, Serpent, SCALE, PARCS, APA, CASMO, DRAGON, ARMI, etc. preferred.
Computational skills.
Good computational expertise required: we consider computers to be the universe at our fingertips rather than burdensome necessities.
Programming experience in any language required, preferably in scientific computing; bonus points for Python, C++, and Fortran 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 NRC under an ASME NQA-1 compliant QA environment preferred.
Strong formal technical documentation skills required.
Ability to consistently deliver to an aggressive schedule.
Self-motivated: able 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.
