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.

The absorption probability of neutrons in a cylindrical sample is considered. The neutron beam is monochromatic and collimated, and its intensity is uniform across the beam. A uniform (one-region) sample and a nonuniform (concentric two-region) sample are considered. An exact solution in an analytic form is found for the uniform case. In the nonuniform case, the exact solution is given in the form of an integral (which should be numerically integrated). In the nonuniform sample, concave (i.e., low in the center) and convex distributions of absorber are considered. Some symmetry in the change in the absorption probability due to the absorber nonuniformity with respect to these types of absorber distributions is pointed out and discussed. The applicability and limitations of the solutions are discussed, and an application example is given.
