A dynamic modeling ³H transfer to the environment under accidental release from the fusion reactor

Tritium inventory and potential release amount of fusion reactor is much larger than which of traditional fission plant. Tritium environmental safety has caused great attention after accidental release from the fusion reactor. In this work, a numerical TAS dynamic module for simulating tritium atmospheric dispersion, soil migration, biological metabolism and human dose has been developed. The comprehensive dose results of TAS module were then compared with UFOTRI code developed by KIT in Germany, and the TAS has been shown to be capable of providing reasonable results with many advantages. Moreover, the dynamic results of tritium concentration in the human body could provide a reference for fusion nuclear emergency.
