Abstract
Using liquid wall between the plasma and solid first wall in a fusion reactor allows to use high neutron wall loads and could eliminate frequent replacement of the first wall structure during reactor’s lifetime Liquid wall should have a certain effective or optimum thickness to extend solid first wall lifetime to reactor’s lifetime and supply sufficient tritium for deuterium–tritium DT fusion driver This study presents the effect of thickness of flowing liquid wall containing 90 mol Flibe+10 mol UF4 or ThF4 on the neutronic performance of a magnetic fusion reactor design called APEX Neutron transport calculations were carried out with the aid of code Scale43 Numerical results brought out that optimum liquid wall thickness of ∼38 cm was found for the blankets using Flibe+10 UF4 whereas 56 cm for that with Flibe+10 ThF4 Significant amount of high quality fissile fuel was produced by using heavy metal salt
