Research Purpose and Outline

Research purpose
The main aim of this project is to establish tritium safety in a D-T fusion reactor. Since huge amount of radioactive tritium must be introduced into the reactor as a fuel, we are facing to lots of safety concerns newly appeared to be solved. Main efforts will be to establish tritium safety in (1) a fueling system keeping continuous D-T burning, (2) tritium exhausting, recovering and refining processes, (3) a tritium breeding system with a breeding rate over 1.0, and (4) tritium monitoring and accounting systems.
In addition, easy isotopic exchange reactions of tritium with hydrogen in water and hydro-carbons result in the contamination of the systems, which require decontamination techniques. The project also aims to provide new insights into basic tritium science and technology.
