Griffin is a deterministic MOOSE-based reactor physics code developed jointly by Argonne and Idaho National Laboratories for multiphysics analysis of various advanced nuclear reactors, including high-temperature reactors (HTRs), molten-salt reactors (MSRs), fast reactors (FRs), and microreactors.

This workshop provides an overview of Griffin’s capabilities for advanced reactor modeling of pebble-bed-type or prismatic-type HTR, MSR, FR, and microreactor applications. It will highlight recent developments for HTR, FR, and microreactor applications, including updated workflows and solver capabilities. The workshop will also cover geometry for complex geometry problems and mesh generation, as well as online cross section generation modeling for both fast and thermal-spectrum systems. A series of application examples across HTR, MSR, FR, and microreactors will be presented to showcase typical analysis tasks and modeling best practices across these reactor types. In addition, the workshop will demonstrate coupled multiphysics simulations with other MOOSE physics tools under steady-state and transient conditions, emphasizing integrated workflows within the MOOSE framework.
