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 fission neutron multiplicity, , of 242mAm(n,f) was measured relative to that of 235U(n,f) using the neutron time-of-flight facility at the Lawrence Livermore National Laboratory 100-MeV electron Linac. Incident neutron energies ranged from 0.037 to 30 MeV. Fission fragments were detected using two hemispherical ionization chambers each containing ∼400 µg of 99.2% pure 242mAm. A separate fission chamber with 8.3 mg of 235U was situated between the two 242Am chambers and provided a normalization at every data point. Fission neutrons were detected in a liquid benzene scintillator using pulse-shape discrimination to separate gamma rays from neutrons. A comparison of the measured energy dependence of is made with semi-empirical models of neutron emission from the actinides.
