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.

Experimental study of the downward melting of a gas-releasing substrate solid surface by a hot liquid pool of different densities was performed. The molten phases of the solid and the liquid pool were mutually miscible. Heating of the liquid pool was obtained by a flat heater grid, suspended in the liquid above the solid surface. The liquid layer beneath the heater grid was thermally stable. After the onset of melting and gas release, the different flow regimes, identified in the case of nongas-releasing solid, were not encountered. The melting rate continuously increased with an increase in the ratio of the liquid density to the melted-solid density, ρ*, attaining a maximum at about ρ* ≈ 1.19, beyond which this rate decreased to even a lower value than that of nongas-releasing solid.
