目前,我国运行和在建的核电站都是滨海核电站,采用一次循环冷却直排方式,温排水排放量很大。核电站温排水排出后,在排放口附近总会存在一个超标区,为了保护水生生物免受温排水的有害影响,许多国家都制定了相应的水温限值或混合区域的范围,而我国目前尚缺乏相关标准,成 At present, nuclear power plants that are under operation and under construction in China are both coastal nuclear power plants, adopting a direct cooling method with circulating cooling and a large amount of warm drainage discharge. There is always a super-boundary near the discharge after the thermal drainage of nuclear power plants is discharged. In order to protect aquatic organisms from the harmful effects of warm drainage, many countries have formulated corresponding water temperature limits or the scope of mixed regions, but our country is still lacking Related standards, into
