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 method for solving internal interface perturbations is offered. The technique used is based on a pattern recognition method that allows conditioning the referential problem and then enforcing the spatial term of the eigenvalue expansion equal to zero. This method is implemented in the VAREC and VARYX codes and is used to calculate variations of the moderation ratio in pressurized water reactor cells caused by an increase in the cladding thickness.
