Stainless steel is used in various nuclear installations as a major structural material. Tritium is produced by several nuclear reactions in these facilities. It is considered that the hydrogen isotope included tritium permeated for stainless steel through the interaction such as dissolution, diffusion and recombination, and is released on the atmosphere. Therefore, it is important to clarify permeation behavior of tritium in stainless steel from the viewpoint for improvement of the social acceptability o...

Study on permeation behavior of hydrogen isotope in stainless steel

Tritium from the nuclear power plants should be monitored at real-time. The development of real-time atmospheric tritium monitor is an important issue, since it was reported that tritium from the nuclear power plants was released as the form of HT and HTO, and released tritium was adsorbed plants and transported to numan through photosynthesis and food chain processes. This study was carried out to develop the separation-condensation technique for tritium using polyimide hollow fiber module. At first, ion ...
