Research & Development
Radiation Transport Methods (RTM)
Objectives and Strategies
- Develop and integrate next-generation neutron transport simulation tools in Virtual Environment for Reactor Applications (VERA)
- Develop pin-resolved predictions of flux, power density and interaction rates using neutron transport theory over the entire core or core subregions
Requirements Drivers
- Pin-resolved 3D full-core transport with depletion including radial, azimuthal, and axial power distributions
- Accommodate tight coupling to computational fluid dynamics (CFD) with conjugate heat transfer, structural analysis, chemistry, and fuel performance models
- Provide transient analysis capability
- Accommodate computing platforms from engineering clusters to leadership systems
- Common cross section processing
- Integrated within Lightweight Integrating Multiphysics Environment (LIME)
Outcomes and Impact
- Development of radiation transport modules for VERA with varying levels of complexity and efficiency
- 3D, full-core pin-resolved neutron transport modeling capability
- Next generation expertise in computational radiation transport
