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 neutron capture cross sections of 240Pu and 242Pu were measured in the energy range from 50 to 250 keV, using 197Au as a standard. Neutrons were produced via the T(p,n) reaction with the Karlsruhe 3-MV pulsed Van de Graaff accelerator. Capture events were detected by a Moxon-Rae detector. A flight path as short as 66 mm was used in the measurements to obtain a sufficient signal-to-background ratio. An overall uncertainty of 7 to 11% was obtained for 240Pu and of 10 to 15% for 242Pu. In the region of overlap between 50 and 90 keV, the presented data agree with our previous results. They confirm the existing data for 240Pu. Discrepancies up to 30% for 240Pu and 242Pu were found in the evaluated ENDF/B-IV files while KEDAK 3 fits reasonably well to the experimental data.
