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.

Cross-section libraries and input neutron spectrum data are generally required in the application of activation neutron spectrometry and are usually given in the form of group values. Fine structures (620 groups for the energy range from 10-10 to 18 MeV) are often used, but problems arise if adjustment codes implying matrix calculations are adopted. In this Note, the errors deriving from the use of a coarse (40-group) structure are estimated and discussed making special reference to a fast neutron spectrum.
