Research Abstract

Through a cooperative research on code development by domestic and overseas researchers for divertor/SOL plasma physics and tritium plasma wall interaction, an integrated simulation code was developed in order to evaluate accurately tritium retention and exhaust in fusion reactors. It includes development of each physical models by means of cross-code and code-experiment comparisons in laboratory experiments and validation and improvement of the integrated code by analyzing experiments in present fusion devices. Taking complicated environment into account, in-vessel tritium retention was evaluated and physical processes for reduction and exhaust were found.
