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 wall heat transfer coefficient for the forced convective two-phase flow of sodium is theoretically derived by using the momentum-heat transfer analogy and a logarithmic law for the velocity distribution in the liquid film. Only one constant in this logarithmic form needs to be empirically determined. The relationship between the film average temperature and the interfacial liquid-vapor temperature is also derived. The results from the suggested correlation are in excellent agreement with the Zeigarnick and Litvinov data over a broad range of parameters. The predictions are also in agreement with the high heat transfer coefficient observed in some General Electric Company experiments. The proposed correlation is found to result in a higher heat transfer coefficient for sodium than do the previously advanced correlations.
