Atmospheric Boundary Layer Monitoring with the SODAR/RASS System on the Belarusian NPP Site

Аннотация

The main purpose of monitoring the atmospheric boundary layer on the Belarusian NPP site is to obtain real-time data on the temperature and wind data, which determine the conditions of atmospheric dispersion of radionuclides in the standard operating regime of the NPP and accidental emissions. Such data are used, first and foremost, in the operation of the automated system monitoring the radiation conditions. The components of the monitoring including the observational and data processing subsystems are described. An array of data from measurements performed since September 2014 has been accumulated and analyzed. Examples of calculations of the characteristics of atmospheric dispersion are presented. It is remarked that such monitoring holds promise in regular investigations of the conditions of migration of the contaminants in the atmosphere of other environmentally dangerous objects.
