Tritium dispersion simulation in the atmosphere from ANGRA I Nuclear Power Plant
In this work, we check the ability of an air pollution model to simulate the concentration of radioactive material emitted from the Nuclear Power Plant of Angra dos Reis, Brazil. To achieve this goal, we solve the time-dependent two-dimensional equation by the Generalised Integral Laplace Transform Technique (GILTT) method. The wind field was reconstructed by the MM5 mesoscale model and the analysis of the results shows a good agreement between the values computed by the model against the experimental ones.
