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.

An attempt is made to describe the in-process inventory of enrichment cascades with a close separation process as a product of gas in-flow and the average holdup time of gas molecules. The holdup time is calculated on the basis of a simple random-walk model of the transients and the output response to input perturbation. Calculations are carried out for a gaseous diffusion plant producing slightly enriched uranium. Experimental determination is proposed for safeguards purposes.
