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.

Measured neutron emission spectra from 14-MeV neutron-induced reactions in a wide range of nuclei are analyzed by precompound nuclear model calculations. The nuclear model code parameters are adjusted using a least-squares fitting procedure to optimize the agreement between calculation and experiment, but the parameters are constrained to physically reasonable values. A single set of input nuclear constants produces calculated spectra that agree to within 30% of experimental values in over 70% of the cases.
