Tritium-material interaction properties in fusion reactor materialsFunded under: JRC-FUSAFE 5C
One of the main concerns of tritium-material interaction is the determination of tritium recycling from, tritium inventory in, and tritium permeation through, the first wall or other plasma facing components of a thermonuclear fusion reactor. Numerical codes, such as TIRP, have been developed to calculate these properties. These codes need several tritium-material interaction parameters as input data: diffusivity D, solubility K(s), heat of transport Q, surface recombination rate K(r), trap concentration c(T) and energy difference between trap and solution sites E(T). This report presents a literature study of D, K(s) and Q, an equation for the calculation of K(r) and some remarks on c(T) and E(T). In addition, a discussion of the effectiveness of permeation barriers on fusion reactor materials is included.
