Abstract
In this paper, we collect and summarize a variety of thermophysical properties of liquid tin, a prospective plasma-facing material in fusion reactors. These include the thermodynamic properties such as density, specific heat, sound speed, and vapor pressure; transport properties such as thermal conductivity, viscosity, and surface tension; and hydrogen isotope solubility and diffusivity. The thermodynamic property data are used to fit an equation of state that accurately reproduces these, which has been implemented in MELCOR for fusion in order to model systems employing liquid tin plasma facing components and coolant loops. Few data on hydrogen solubility could be found, and these differ by some orders of magnitude; diffusivity appears not to have been measured precisely; and, for subsequent analyses, theoretical estimates will have to be relied upon.
