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 state of the JEF-2 evaluation of 238 U + n cross sections in the region of unresolved resonances (∼10 to 300 keV) is reported with special emphasis on recent progress in theory (rigorous expressions for resonance-averaged cross sections with arbitrary level overlap), which permits reliable model-aided evaluation and parameterization by simultaneous fits to total, capture, and inelastic scattering cross-section data. Formalized inclusion of information from resolved resonances via Bayes' theorem has helped to remove discrepancies between resolved and unresolved parameters and has improved resonance statistics. Comparison with the latest ENDF/B-VI (pointwise) evaluations of the capture and the total cross sections shows agreement within 1 to 3%.
