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 previously developed formalism is applied to calculate the sensitivity of cobalt prompt response self-powered neutron detectors. Differential and average sensitivities in thermal and epithermal energy regions are calculated, and their dependence on the geometrical factors is studied. A simple analytical expression is proposed for the first-collision absorption probability, which is a good approximation to the exact function. This expression is used to obtain the epithermal selfshielding factor as a function of the radius of the emitter and the parameters of the interaction. The thermal sensitivity, as the main contributor to the current, is studied as a function of the emitter radius. Finally, a criterion to evaluate the accuracy of the parameters of the model is established in the form of some interval rule. This interval rule should encourage the performance of better measurements and calculations.
