Reactor Multiphysics Methods Developer

Idaho National Laboratory•Idaho Falls, ID

11d•Onsite

About The Position

Idaho National Laboratory needs a Reactor Multiphysics Methods Developer to develop, deploy, and support innovative technical solutions. We develop several reactor physics tools based on the Multiphysics Object-Oriented Simulation Environment (MOOSE) framework in collaboration with other partners. The candidate will support development of Griffin which is a deterministic reactor physics code based on MOOSE written in C++ and Fortran. This includes software work and development of novel methods for solving reactor physics problems. The candidate will also support multi physics modeling efforts for advanced reactors using Griffin couples to other multiphysics tools. In support of analysis and code validation and verification, the candidate will also use Monte Carlo tools. The candidate will work with teams of engineering using Griffin to support their modeling efforts and participate in teams of engineers in support of advanced reactor model development and analysis.

Requirements

PhD of Science in Mathematics, Engineering, Computer Science, or related discipline from an accredited institution.
Experience with C++, Fortran, and multi-physics modeling.
Excellent verbal and written communication skills.

Nice To Haves

Experience with MOOSE framework, Griffin, and Monte Carlo tools.
