摘　　要：随着核电的发展和环境保护需求的日益增强,核电厂排氚问题也越来越受到重视,如何降低核电厂氚的产生和废液处理已成为当前的难点之一。本文通过对压水堆核电站氚的产生和释放机理进行了分析,得出了一回路中氚的主要来源;同时,对电厂各个系统中氚含量进行监测与分析,掌握了正常运行期间整个系统内各个部分的氚含量水平变化趋势;最后,对几个氚处理的方式进行对比分析,得出对于目前的压水堆核电厂而言,环境排放是采取的主要方式。With the development of nuclear power plant and the increasing demand for environmental protection,the discharge of tritium from nuclear power plant has become more and more important.How to reduce the production of tritium and waste liquid treatment in nuclear power plants has become one of the current difficulties.This paper briefly described the production and release mechanism of tritium from PWR nuclear power plants,and obtained the main source of tritium in the primary system.At the same time,the tritium was monitored and analyzed in each system of the nuclear power plant,and known that the trend of tritium content level in the whole system during normal operation.Finally,after several tritium treatment methods were compared,it show that the environmental discharge is the main way for current PWR nuclear power plants.
