Powering the future: How the DOE is fueling nuclear fuel cycle research and development
As global interest in nuclear energy surges, the United States must remain at the forefront of research and development to ensure national energy security, advance nuclear technologies, and promote international cooperation on safety and nonproliferation. A crucial step in achieving this is analyzing how funding and resources are allocated to better understand how to direct future research and development. The Department of Energy has spearheaded this effort by funding hundreds of research projects across the country through the Nuclear Energy University Program (NEUP). This initiative has empowered dozens of universities to collaborate toward a nuclear-friendly future.

The thermal-hydraulic behavior of rotating bed reactors is analyzed using the drift-flux model to predict fuel bed expansion. A new correlation for onset of fluidization is developed for this purpose. Parametric effects are discussed and first priority research areas are delineated. Reactor design curves are developed showing small cores between 25- and 50-cm radius should be capable of generating power up to 5000 MW. With exhaust temperatures approaching 3000 K using hydrogen as a propellant, these devices seem especially suited for use in space-tug concepts.
