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 new approach for calculating neutron self-shielding factors taking into account isotropic multiple scattering, recently developed for the thermal region, is extended to epithermal resonance energies. The method is based on a collision function determined solely by the cross sections and the geometry of the probe submitted to the neutron field. The influence of the external field is separately included in the first collision probability distribution. Some advantages of the method with respect to the transport theory are discussed. Numerical results for the main epithermal resonances in cobalt and gold are presented, including the self-shielding factor as a function of the incident neutron energy.
