TL;DR: In this paper, the use of zirconium-palladium windows for tritium separation is shown to have many advantages over the best alternative devices, based on the materials properties and costs as they stand in 1983.
Abstract: Any first generation fusion power reactor must be surrounded by a heat tranfer medium and a tritium breeder-blanket containing lithium in some form. Liquid lithium and liquid lithium alloys are considered to be particularly attractive choices for both purposes; the main disadvantage of these materials is the difficulty of tritium separation. The use of zirconium-palladium windows for tritium separation is shown to have many advantages over the best alternative devices. This is based on the materials properties and costs as they stand in 1983. The design of a typical permeation window resembles that of a shell and tube heat exchanger; liquid lithium or lithium alloy loaded with tritium from the reactor, flows through on the zirconium side of the window, while a purge stream of argon and oxygen flows through on the side with the palladium coating. Oxygen is present so that sufficiently low tritium pressures may be maintained on the downstream side of the window. Tritium is recovered as T2O. Data ar...

TL;DR: In this paper, a new technique for LME studies has been designed that makes use of the SPT coupled with a XPS/Auger spectroscopy analysis, where the interface between the material (T91 steel) and the liquid metal (PbBi) can be varied to investigate the interplay between the oxide nature or the thickness and crack initiation induced by a liquid metal.

TL;DR: In this paper, numerical simulations of the flow of liquid metal in a vertical pipe are performed, where the mean flow is directed downward, a half of the pipe's wall is heated, and a strong horizontal magnetic field perpendicular to the temperature gradient is imposed.

TL;DR: In this paper, a transient instrument with a liquid metal inglass probe to measure the thermal conductivity of high-temperature melts has been developed, where a wire heat source in the conventional hot-wire method was replaced by a mercury thread contained in a glass capillary.
Abstract: A transient instrument with a liquid metal in‐glass probe to measure the thermal conductivity of high‐temperature melts has been developed. A wire heat source in the conventional hot‐wire method was replaced by a mercury thread contained in a glass capillary. This modification has made it possible to apply the transient method to electrically conducting liquids at high temperature. Satisfactory results were obtained for HTS (Heat Transfer Salt) in the temperature range 457–580 K.

TL;DR: In this article, the influence of casting and baffle geometry, mold thickness as well as withdrawal speed on solidification conditions and resulting microstructure was examined for the case of simple cylindrical castings and found that the nature of the baffle has a stronger effect than the different mechanism of heat dissipation.
