Physics Integration (PHI)

Integrating the CASL Virtual Reactor

Objectives and Strategies

  • Completion of the VERA Core Simulator (VERA-CS) to provide a platform
  • for challenge problem physics integration
  • Coupling development to integrate advanced M&S capabilities to achieve challenge problem solutions
  • A strong VERA infrastructure supporting software development, testing, and releases.

Requirements Drivers

  • Reactor modeling through full power steady-state operation with improved physics
  • Challenge Problem analysis capabilities through multi-physics integration of advanced physics capabilities being developed by MPO, THM, RTM
  • Enable use of VUQ methodologies for quantification of uncertainties
  • Deployment and use of VERA

Outcomes and Impact

  • An advanced modeling and simulation environment for nuclear reactor analysis
  • Physics integrated through PHI-developed coupling methods being used to address challenge problems
  • VERA deployed through Test Stands and used on Leadership Class computers
  • Moving from VERA development to its use applications
