Currently, Japan is planning to construct the Japan Fusion Demonstration Plant (JA DEMO) to deploy fusion energy. This makes it essential to consider environmental safety under both normal operational and accidents. The fusion reaction used Deuterium and Tritium as fuel. While deuterium is a stable isotope of hydrogen and poses no radiological hazards, however tritium requires careful handling and monitoring, due to the risk in the event of release or accidental release. This study simulated the atmospheric dispersion of tritium using UFOTRI code, a Gaussian plume-based model developed in Germany. Although originally designed for European conditions, this research adapted its to reflect the local conditions of Rokkasho, Aomori prefecture, a candidate site for fusion facility. The simulation evaluated tritium dispersion under various release heights to estimate the equivalent effective dose form long-term exposure by using a 50-year integration time to calculate the collective committed effective dose equivalent (EDE) 1). |
