Lead Engineer – Reactor Nuclear Physics & Methods

Reactor Physics Technology Team Member

This role contributes to company objectives in the field of reactor physics and technology. This role is intended for a current or future subject matter expert in the areas of neutron transport, cross section generation, and code development/maintenance in these areas. This role also supports software documentation and validation, user training, and customer interfacing for lattice physics codes (LANCR) and the 3D core simulator (PANAC).

This role is within the Reactor Physics Technology (RPT) team, which is responsible for the development, maintenance, analytics, technical consultation, and licensing stewardship of engineering computer codes, correlations, and methodologies related to Boiling Water Reactors (BWRs) and Small Modular Reactors (SMRs). RPT is also responsible for supporting customers with emergent questions in the areas of reactor neutronics, thermal-hydraulics, and instrumentation physics and contributes to the nuclear and thermal-hydraulic design of new fuel products.
