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.

Neutron emission spectra from targets bombarded by 318-, 590-, and 800-MeV protons are analyzed. At each emission angle the major features of the emergent neutrons throughout their energy range can be described by the sum of four evaporation terms. The characteristic emission temperatures are approximately the same for eight targets in the mass range of A = 12 to 238. The (p,xn) cross section at an incident proton energy of 590 MeV varies very nearly as A4/3. A parameterized model with parameter covariances is developed that describes for the above proton energy range the essential features of neutron emission spectra including quasi-elastic peaks. Calculation times are very short, of the order of 1 s.
