[en] Tritium is the fuel of fusion reactor, and the issue about tritium is one of the most critical problems to be solved in fusion energy. It's very important to solve problems about both science and technology in tritium chemistry to support the development of tritium facility. Besides, tritium measurement is the main way to obtain the information about tritium in the facility. In this article, we reviewed the progress about tritium chemistry and tritium analysis developed recent years, and also give a prospect about it. (authors)
