Abstract

The behavior of tritium contained in the biofuel produced by the fusion energy is analyzed. Hydrogen product is contaminated with tritium from breeding blanket of fusion plant within the regulation limit and released to atmosphere when used for fuel cell vehicles. In the model city, Osaka, seven-compartment model describes the behavior of exhausted tritium by adapting the environment water flow and its migration was analyzed with STELLA system dynamics code. Tritium (HTO) with a concentration of 5000 Bq//m³ exhausted from the running vehicle increases decades and reaches steady state after about 50 years, at around 40 Bq/m³ in atmosphere and 4 Bq/L in surface soil water that does not deserve health hazard, however causes contamination of large populated area.
