Abstract

A computational prognostic system (CPS)“BAKIS” is intended for forecasting and assessing a radioactive contamination of surface water objects in the vicinity of Russian nuclear facilities taking into account major factors defining migration of radioactive substances in aquatic medium. The system will be used for solving various practical problems such as radiation and ecological safety cases for nuclear facilities during their operation and in the process of decommissioning, calculation of permissible discharges of radioactive substances into water objects by operating and designed nuclear facilities, assessment of  medium- and long-term consequences of a water object contamination,support to decision-making on counter-measures in the events of accidents, calculation of transboundary transfer of radioactive substances in aquatic medium, etc.

The basic paths of radioactive inflows to water objects, factors, events, processes and phenomena defining their distribution and accumulation in water objects are discussed as well as the key requirements to the developed CPS.

KeywordsRadioecology, radioactive contamination, water objects, models of radioactive substance migration, forecast and assessment of discharge consequences, computational prognostic system, safety case
