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.

Expressions are developed for the first-order change in the fundamental eigenvalue due to a simultaneous perturbation in the interior operator and the internal interface of a (reactive) system. The perturbation formulas are derived for both energy-dependent neutron transport theory and its diffusion approximation. Several numerical examples are given.
