Center for Used Fuel Research: Building confidence in storage and transport
Used nuclear fuel storage and transportation have reached a critical juncture.
Dozens of utilities need reliable data on how used nuclear fuel performs in dry storage casks and canisters to extend regulatory licenses at sites across the United States. Likewise, the Department of Energy expects to take ownership of the used nuclear fuel—termed “spent nuclear fuel” in the laws and regulations governing its stewardship—and transfer it to one or more federal staging facilities for management and disposition.
Meanwhile, dozens of reactor companies are testing prototypes of advanced reactors and advanced reactor fuels. Eventually, regulators and industry must also verify the safety and security of storage methods for these advanced fuel types.
To help address these challenges, the DOE established the Center for Used Fuel Research (CUFR) in January 2026 for work related to the long-term storage and transport of used nuclear fuel.

Governor's Square 10
Price: Free
Capacity: maximum of 40 persons
Host: Argonne National Laboratory / Idaho National Laboratory
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.
