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 approximate method for calculating the interference of neutron streaming between different regions (drawers) in fast critical assemblies is described by applying the well-known Benoist formula to super cell problems. The interference effect on the diffusion coefficient was numerically evaluated and the results are compared with those obtained by Yoshida’s method. Sodium void worths in control rod positions (control rod follower channel) relative to the sodium-filled channel are calculated on the basis of diffusion theory with the interference effect and compared with the results obtained from transport calculations. The comparison reveals that the inclusion of the interference effect improves the calculational accuracy remarkably.
