Abstract
A PC-oriented Emergency Response System in case of nuclear accident (BERS) has been developed and works operationally at the Bulgarian National Institute of Meteorology and Hydrology (NIMH). The creation and the development of BERS was highly stimulated by the ETEX (European Tracer EХperiment) project. BERS comprises two main parts - operational and accidental ones. The operational part runs automatically every day. It prepares the input meteorological file used by both trajectory and dispersion models, runs the trajectory model for 35 European Nuclear Power Plants (NPP), visualizes the results and uploads the maps of trajectories to a dedicated web-site. The accidental part is activated manually when a real radioactive release occurs or during emergency exercises. Its core is the Bulgarian dispersion model EMAP. Outputs are time sequences of concentration and accumulated deposition fields. In the paper, the new version of BERS regarding mainly the operational part is presented. The main improvement is in the simulation of concentration and deposition fields applying mesometeorological and dispersion models in the operational part, as supplement to trajectory calculations.
