Probabilistic approach to establishing the standard levels of emissions and discharges from a nuclear power plant

The theory of checking statistical hypotheses is used to elaborate the probabilistic approach to establishing the reference levels of emissions and discharges from nuclear power plants. Expressions are obtained and a scheme is proposed for establishing these levels. The scheme is based on optimizing the indicator and control functions and the monitoring sensitivity. For more effective monitoring, it is proposed that when the reference levels are established the operating regimes of the power-generating units of a nuclear power plant be divided into operation at power and a regime of planned preventative maintenance. Using as an example the first unit of the Khmel'nitsk nuclear power plant, the characteristics of the statistical distribution of the various components of real gas-aerosol emissions are determined and the corresponding reference levels are calculated.
