Responsibilities

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.

The environment is dynamic and evolutionary, and as such, new responsibilities often arise, and you should be capable of and excited about learning and applying specialized skills.
