Evaluation of the Contribution of Technogenic Radionuclides to the Total Activity of NPP Emissions on the Basis of a Simulation Model

Abstract

An approach to evaluating the contribution of different sources of technogenic radionuclides to the total activity of emissions on the basis of a simulation model is proposed. The model is verified and the principles of application of the new approach in NPP are determined. The fl ow of radionuclides into surface waters can be determined by modeling their kinetics in the reservoirs of the balance scheme of the NPP. At the control points, the discrepancy between the computed and measured specific activity does not exceed 50 mBq/liter, which is comparable to the determination errors.
