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 23Na(n,2n) reaction produces the radioactive product 22Na, with a half-life of 2.61 years. For sodium-containing systems this reaction can result in a radioactive contamination problem. Currently available experimental cross sections for this reaction are in strong conflict. Comprehensive nuclear model calculations performed as part of the sodium evaluation for ENDF/B-V are in agreement with one of the experimental data sets. Acceptance of this data set results in an (n,2n) cross section larger than was given in ENDF/B-IV by ∼37% at 15 MeV and by as much as a factor of 4 at 20 MeV.
