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.

A filtered neutron beam technique has been used to measure changes in an average total neutron cross section of tin. The cross section was averaged over a neutron energy band from 23.1 to 24.9 keV, which covers a number of resonances. This average cross section, when measured for a sample of intermediate thickness, shows the effect of Doppler broadening of the resonances. The effective average total cross section increases as the temperature of the sample increases with a change of slope at the gray-to-white tin transition and a step at the melting point. The changes of slope and steps are evidence of changes in the thermal motions of the tin atoms in the sample when the sample changes its physical state.
