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 class of finite difference methods, the linear one-cell functional methods, is introduced, and observed to encompass the vast majority of spatial approximations used in one-dimensional transport theory. It is noted that, under minimal additional assumptions, these methods satisfy the classical result, valid for one-step finite difference approximations to initial value problems, that consistency implies both convergence and stability. This explains the observed absence of nonconvergence and instability from ray-tracing calculations, and also indicates the limitations of this result.
