Abstract

The SINAC (Simulator Software for Interactive Modelling of Environmental Consequences of Nuclear Accidents) program system has been developed in the Hungarian Academy of Sciences Centre for Energy Research and has been used as a decision support system in the Centre for Emergency Response, Training and Analysis (CERTA) of the Hungarian Atomic Energy Authority (HAEA). The aim of the software is to calculate the spread of deposition of radioactive material emitted into the atmosphere and to analyze the consequences of release from an accident of a nuclear power plant. Atmospheric dispersion, plume depletion by dry deposition and wash out, cloudshine, groundshine, inhalation and ingestion doses in early and late phase are assessed by the software. For a decision support system like SINAC, it is important to take into account the changes in meteorological parameters both in space and time and crucial to have a short calculation time. The calculations are based on a Gaussian puff model, instead of a plume model, which would not consider the change in meteorology, or a particle model, which would prolong the run time of the calculation. The meteorological data necessary for the calculations is provided by the AROME numerical weather prediction model used by the Hungarian Meteorological Service (OMSZ).
