摘　　要：液态流出物排放对环境的影响问题是内陆核电建设过程中重点关注的问题之一。分别应用康奈尔混合区专家系统(CORMIX)的3个主模块(CORMIX1/2/3)实现了对内陆某典型滨河核电厂液态流出物3种排放方式(淹没式单孔、多孔(扩散器)和表面排放方式)下环境影响的对比分析和优化计算。研究结果表明:如果以"相对稀释倍率S=20等值线的包络面积"作为单一的筛选条件,3种排放方式的优先顺序依次为:多孔排放(扩散器)>淹没式单孔排放>表面排放。该结果可为核电厂流出物排放方式的设计和优化选择提供参考。The environmental impact of liquid effluent discharge is one of the important problems to be focused on regarding the construction of inland nuclear power plants, in this paper, with respect to three modes of effluent discharge from a typical inland riverfront nuclear power plant, i.e., multiport-diffuser discharge, submerged single port discharge and surface discharge, the comparative analysis and optimization calculation of the environmental impacts of the effluent discharges were performed by using three main modules （CORMIX1/2/3） of the CORMIX. The result of the study showed that given the unique screening condition as area of the relative dilution ratio S=20 contour envelope, the first priority of the three kinds of discharge modes was multiport--diffuser discharge, then submerged single port discharge; while surface discharge was undesirable. The results will provide the reference for optimization design and screening of effluents discharge mode for inland nuclear power plants.
