基于生态成本核算的滨海核电厂淡水水源选址研究

Research of choice of fresh water sources for coastal nuclear power plant based on ecological cost accounting

目前核电厂水源选址工作尚未将生态环境纳入选址影响因素进行分析。本文以滨海核电厂为分析对象,提出利用机会成本法、市场价格法及恢复/防护法计算核电厂取水过程产生的生态成本,以此量化工程对生态的影响程度。最后以福建莆田滨海核电厂水源选址工程为例,建立了水源选址影响因子评价体系。分析结果表明:是否考虑生态因子对评价结果排序有一定的影响,考虑生态因子的方案计算结果合理、可行。结果可为相关水源选址提供参考。

The site selection of water sources for the nuclear power plant did not consider ecological envi-ronment in recent work. In this paper, the ecological cost in the water extraction was calculated using the opportunity cost method, market price method and restoration/protection method to quantify the influence of coastal nuclear power plant on the ecology. Taking the Putian nuclear power plant in Fujian province as a study case, the ecological impact evaluation system for site selection of water sources was built. It made a difference whether to consider the ecological factors on the evaluation. The study shows that the evaluation system with ecological factors is reasonable and feasible, which can provide reference for the site selection of water sources for the nuclear power plant.
