We describe the parameterization of a tungsten-hydrogen empirical potential designed for use with large-scale molecular dynamics simulations highly irradiated tungsten containing hydrogen isotope atoms, and report test results. Particular attention has been paid to getting good elastic properties, including relaxation volumes small defect clusters, interaction energy between isotopes typical irradiation-induced defects in tungsten. conclude that ordering changes ratio H atoms point defects,...
In fusion test reactors and power plants, one of the significant concerns is retention hydrogen isotopes in wall materials. Especially isotope tritium, which radioactive, great concern. Knowing other isotopes, such as deuterium, also important due to several reasons. Deuterium known affect mechanical properties material most experiments are carried out on deuterium for its more safe use than tritium. addition affecting material, has been observed defect accumulation if it irradiated...
