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.

Director of Fusion Energy Technologies
General Atomics
Brian Grierson serves as the Director of Fusion Energy Technologies at General Atomics, where he oversees Fusion Systems Integration, RF Systems, Diagnostics Development, and Engineering Research & Innovation within the Energy Group. In this role, he leads multidisciplinary teams advancing the critical technologies and integrated systems needed to support the development of practical fusion energy solutions and related applications.
Prior to joining General Atomics, Dr. Grierson spent more than a decade at the Princeton Plasma Physics Laboratory, where he held leadership positions including Division Head and Principal Research Physicist, contributing to domestic and international magnetic fusion energy research. He earned his Ph.D. in Applied Physics and Applied Mathematics with Distinction from Columbia University.
Dr. Grierson’s work focuses on advancing fusion energy through system integration, technology development, and the translation of scientific innovation into real-world energy applications.
