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 is proposed for the analytical calculation of resonance integrals. Resonance integrals of infinite cylindric fuel cells are calculated according to a very simple analytical method with a reasonable level of accuracy. An escape probability based on a rational approximation is used to represent the neutron transport among the cell regions. The expression obtained for the resonance integral is a function of the temperature, geometry, and fuel rod composition, as well as the neutron energy. The terms of the expression are combinations of the well-known function J(ξ,β) and its partial derivatives in β. The formulation can be used for all resonance types (narrow, intermediate, and wide). The method parameters depend on the resonance type and can be obtained as a function of a single parameter. For this parameter, a simple expression dependent on the resonance parameters is proposed.
