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.

A new nodal interface diffusion equation is derived by applying the second form of Green’s theorem to the transverse-integrated diffusion equation. By virtue of this integral equation, a unified theory of the nodal interface partial current method and the nodal interface net current or flux method is established. Use of the infinite-medium Green’s function in that equation results in the same interface partial current equation as the nodal Green’s function method. The nodal interface net current equation can be proven to converge and demonstrates a computational efficiency superior to the nodal interface partial current method for standard benchmark problems.
