  • Investigation of tritium inventory and permeation behaviour in the liquid breeder blanket concept of DEMO as a function of design and material parameters

Abstract

A numerical code has been used to estimate the time dependence of tritium inventory and tritium transport into the coolant, into the first wall boxes and through the liquid breeder in the Pb-17Li blanket concept of DEMO. Several aspects of design and material parameters have been considered. The effect on inventory and permeation of coatings with low surface recombination coefficient and/or low diffusivity at various surfaces of the structural material has been studied. TiC has been chosen as a reference material for these calculations, and a general database on coating efficiency as a function of its properties, based on the TiC data, has also been set up.
