CASL

Radiation Transport Methods (RTM)

RTM Vision Statement

Objectives and Strategies

  • Objective: Deliver next-generation, non-proprietary, scalable radiation transport simulation tools to VERA, incorporating the latest VUQ technologies
  • Strategy: develop and deploy deterministic and Monte Carlo methodologies for 3D pin-resolved transport with coupled multiphysics capability

Requirements Drivers

  • Challenge problems require pin-resolved (radial, azimuthal, and axial) 3D full-core transport with depletion and TH feedback
  • Accommodate tight coupling to subchannel, CFD, structural analysis, and fuel performance models
  • Integrated within VERA and VERA-CS and used with coupled physics modules or as standalone neutronics module

Outcomes and Impact

  • Outcomes:
    • Development of validated deterministic and stochastic radiation transport modules for VERA to support reactor analysis with multiphysics coupling
    • Publication and dissemination of new methods that will enhance the state-of-the-art of reactor neutronics
  • Impact:
    • Provides radiation transport capability to address all CASL Challenge Problems
    • Advance state of the art in computational radiation transport
    • Contribute to other DOE/NNSA needs/missions
