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.

To exclude the reflector region during core calculations, the relationship between group currents and fluxes is investigated in a 60-deg homogeneous sector. With given normal currents on the boundary, a two-dimensional analytical solution to the four-energy-group diffusion equation is derived. Furthermore, a numerical procedure is presented to calculate the flux distribution on the boundary, with a given normal current distribution there. Numerical results are presented to illustrate the coupling between fine-mesh cell edges and between energy groups, as well as to illustrate the impact of the current distribution on the flux distribution.
