In transition: Commercializing fusion power
Commercial fusion power is closer than ever. There are now around 30 U.S. fusion companies, several of which claim to be on track to connect to the grid as early as the 2030s.
Tokamak and laser inertial confinement approaches benefit from decades of research at facilities such as the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory and ITER, with alternative concepts including stellarator, magnetic mirror, and Z-pinch confinement also making notable progress as private and government funding for fusion increases.

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.
