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 chi-square (χ2) values, which represent the degree of agreement between the calculated total, nonelastic, and differential elastic cross sections and their experimental values, are calculated for seven kinds of optical potentials: the phenomenological optimal optical potential (OOP) for a specific element, the global phenomenological optical potentials given by Becchetti and Greenlees (BGP) and by Varner et al. (CH86) for a large number of target nuclei, and the microscopic optical potentials based on conventional Skyrme force (SII and SIII), generalized Skyrme force (GS2), and modified Skyrme force (SKa). Fourteen natural elements (each containing one to four isotopes) are calculated with 12 to 20 neutron incident energies, which are in the 0.1- to 24-MeV energy region for each element. The calculated average total chi-square values are = 0.309, = 0.807, = 0.684 = 0.600, = 0.646, = 2.587, and = 1–368. The conclusion is that the microscopic optical potential based on generalized and modified Skyrme force (GS2 and SKa), which has an analytical formalism without any free parameters, is useful in nuclear data calculation and evaluation.
