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.

An estimate of the cross sections of nuclear reactions with thermal neutrons in terms of the average parameters of the target nucleus (the strength function, the average level spacing, and the average reaction width) is obtained. The probability distributions for the ratios of actual thermal neutron cross sections to their estimated values are introduced. These functions can be calculated from the statistical model. They are calculated for neutron radiative capture and for inelastic neutron acceleration by the isomeric nuclei [as well as the (n, α) reaction, etc.]. Using these results, one can predict the probability of finding the actual thermal neutron cross section in a given interval.
