“…Liquid metals, particularly lithium, lead-lithium, and sodium have persistently been considered as coolants for both fission [56] and fusion [5]. For fusion, this has included use as both coolant and as plasma facing material for blanket and divertor applications (e.g.…”

Tungsten is the favoured armour material for plasma facing components for future fusion reactors, but studies examining the use of tungsten or other refractory metals in the underlying cooled structures have historically excluded them, leaving current concepts heavily dependent on copper alloys such as copper chrome zirconium. This paper first outlines the challenge of selecting an appropriate alternative material for this application, with reference to historical selection methodology and design solutions, and then reexamines the use of refractory metals in the light of current design priorities and manufacturing techniques. The rationale for considering refractory alloys as structural materials is discussed, showing how this is the result of relatively small changes to the logic previously applied, with a greater emphasis on high temperature operation, a re-evaluation of current costs, a relaxation of absolute activation limits, and the availability of advanced manufacturing techniques such as additive manufacturing. A set of qualitative and quantitative assessment criteria are proposed, drawing on the requirements detailed in the first section; including thermal and mechanical performance, radiation damage tolerance, manufacturability, and cost and availability. Considering these criteria in parallel rather than sequence gives a less binary approach to material selection and instead provides a strengths and weaknesses based summary from which more nuanced conclusions can be drawn. Data on relevant material properties for a range of candidate materials, including elemental refractory metals and a selection of related alloys are gathered from a range of sources and collated using a newly developed set of tools written in the python language. These tools are then used to apply the aforementioned assessment criteria and display the results. The lack of relevant data for a number of promising materials is highlighted, and although a conclusive best material cannot be identified, refractory alloys in general are proposed as worthy of further investigation.

“…The viscosity of liquid metals and alloys is known to be very low (lower than water), which leads to several potential applications, like reactor coolant in the case of Na-K [1]. However, due to difficulties to measure such low viscosity, and because alkalis are highly reactive, there are no recent experimental data of the viscosity of this alloy.…”

The shear viscosity of liquid Na-K alloys is computed from molecular dynamics simulations using the Green-Kubo formalism. Interatomic interactions are described using effective pair potentials obtained from Fiolhais pseudo-potential and self-consistent screening. The composition dependence of the viscosity is first investigated at 373 K, then its temperature dependence at three different compositions, namely Na 10 -K 90 , Na 50 -K 50 , and Na 90 -K 10 . Simulation results are first compared with available experimental data. The evolution of the viscosity of the alloys versus temperature is similar to that of a pure one component fluid. This is discussed in connection with the chemical order of the mixtures.
