Analyses and experiments on the integrity and lifetime predictions of plasma-facing components in fusion reactors

Analyses and experiments on the integrity evaluation and lifetime predictions of plasma-facing components in fusion reactors such as first walls, divertor plates and pumped-limiter plates have been performed. Results of the following issues have been obtained. (1) Examination of life-limiting factors based on One-dimensional calculations; (2) Plastic deformation impact based on two-dimensional elastic-plastic analysis; (3) Sputtering and redeposition analysis; (4) Thermo-mechanical analysis of the first wall subjected to one-sided heating; (5) Melting and evaporation experiments of solid walls subjected to intense heating; (6) Melt layer stability; (7) Thermal fatigue tests of tungsten-copper duplex structures for divertor plates; (8) Torsional fatigue tests of tungsten-copper butt joints; (9) Analysis of eddy current and dynamic electromagnetic force; (10) Experiments on the dynamic deformation of ferritic and non-ferritic metal caused by electromagnetic force.
