Progress of Tritium Chemistry and Technology in Fusion Energy

To realize controlled fusion on the earth has been a dream of human being. Owing to extensive research and development, the fusion reaction of D and T seems to be realized. However, to realize a D-T fusion reactor as an energy source, lots of engineering issues still remain to be solved. Among all, T-relating issues are quite important, because T is radioactive and its resources are quite limited. In this paper, tritium chemistry and technology to establish the D-T reactor as an energy source are summarized.
