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 problem of temperature jump, based on the linearized Boltzmann equation and arbitrary gas/surface interaction, is solved using the Sn method and collocation and finite element treatment of the energy (speed) variable. Accurate numerical results for the jump and for the density and temperature profiles are reported for the case of rigid-sphere intermodular interaction and for Maxwell’s diffuse-specular reflection boundary condition.
