The irradiation defects will be introduced to plasma facing materials,especially tungsten(W)by both energetic ions and 14 MeV neutrons produced by fusion reaction,where hydrogen isotopes would be stably trapped,leading to the enhancement of fuel retention.In our previous study,it was found that the hydrogen isotope behavior for W damaged by 14 MeV neutron was clearly different from that by heavy-ion with low damage concentration.To estimate hydrogen isotope retention behavior in actual fusion reactor condition,the hydrogen isotope retention behaviors for heavy-ion irradiated W with various damage profiles were evaluated.
