Research Abstract

Two research groups "A01: Experimental studies on in-vessel tritium inventory in complicated environment of fusion reactors" and "A02: Theory and code development for evaluation of tritium retention and exhaust in fusion reactor" are organized to enhance efficiency and impact of their research on fusion energy development by holding meetings for information exchanges and discussions.
