[en] The discharge of liquid effluents is one of the important environmental issues for the operation of inland nuclear power plants. In this article, the framework of management system and specific regulations about controlling the discharge of liquid effluents from nuclear power plants in China are described. Based on the analysis of actual monitoring data of discharges from domestic and oversea nuclear power plants, radiation environmental impact on the receiving water body during normal operation of inland nuclear power plants and potential environmental risk under accidental conditions are discussed, respectively. Finally, some suggestions about the measures for radiation environmental risk control are proposed. (authors)
