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.

Three neutron transport problems involving two different media are solved in two-group theory for isotropic scattering based on the singular-eigenfunction-expansion solution of the transport equation. This work has two purposes: First, it is shown that two-media problems in two-group theory can be reduced to regular computational forms using the half-range orthogonality theorem; second, in support of benchmark activities, three model problems are defined, and their solutions are reported based on an exact theory.
