我国核电厂极低放废物的优化管理研究

Research on optimal management of very low level radioactive waste from nuclear power plants in China

随着国内放射性废物分类标准的颁布实施,各核电厂运营单位开始关注放射性废物的分类管理。其中,核电厂运行过程中产生的极低水平放射性废物,具有放射性水平低、废物量大的特点,若作为低放废物管理,不仅增加运行成本,占用核电厂废物暂存空间,而且会占用处置场的资源,不利于放射性废物最小化管理。本文分析了国内极低放废物管理现状,结合国际极低放废物管理技术和良好实践,提出我国极低放废物的优化管理建议。

With the promulgation and implementation of domestic radioactive waste classification standard,operators of nuclear power plants began to pay attention to classified management of radioactive waste.Among them,very low level radioactive waste generated during the operation of NPPs have the properties of low radioactivity and large quantities.If they are managed as low-level waste,it will not only increase the operation cost,but also occupy the resources of the disposal site,which is not conducive to the minimization management of radioactive waste.Based on the current situation of domestic VLLW management,combined with the technology and good practices of international treatment and disposal of VLLW,this paper proposes an optimized management route for VLLW in China.
