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 deuterium exchange reaction between water vapor and hydrogen gas is studied at 1 atm total pressure and temperatures from 150 to 250°C using a commercially available platinum-impregnated alumina catalyst. Below a water vapor pressure of 190 Torr, two reaction processes, an external mass transfer of hydrogen and an adsorption of water vapor on the surface of the catalyst, are involved in the rate limiting transfer step. Above 190 Torr, external mass transfer of hydrogen governs the reaction rate. An activation energy of 1.5 ± 0.6 kJ/mol is obtained for this transfer step.
