Study on Water Resources Safety Evaluation for Inland Nuclear Power Siting

Water resources safety is a crucial prerequisite for nuclear power development and a key component of the safety system for inland nuclear power. Based on an analysis of the influencing factors of water resources safety during the site selection stage of inland nuclear power, this paper constructs an evaluation index system for water resources safety in this stage using the Pressure–State–Response (PSR) model. Combining current technical standards related to nuclear power site selection with Strictest Water Resources Management System formulated by the Chinese government, the evaluation standards for water resources safety during the site selection stage of inland nuclear power are established. Two water resources safety evaluation models for inland nuclear power plant site selection are presented, employing the Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation Method (FCEM) respectively. Finally, the water resources safety evaluation system established in this paper is applied to the water resources safety evaluation during the site selection stage of Xiaomoshan Nuclear Power Station. The evaluation results of the two models are basically consistent, and both conclude that the water resources safety during the site selection stage of Xiaomoshan Nuclear Power Station could be basically guaranteed. This provides an effective means for the water resources safety evaluation during the site selection stage of inland nuclear power plants.
