| Research Abstract |
In order to understand tritium accumulation behavior and to develop tritium removal methods in fusion reactors, experimental researches have been done for retention and permeation under mixed ion irradiation, retention in high-energy ion damaged tungsten, generation and retention of dust particles, erosion-transport-deposition of wall materials and its effects on retention in JT-60U tokamak, and removal of hydrogen isotopes from redeposition layers. Many useful results have been obtained for estimation of T retention in fusion reactors.
