田湾核电基地废物最小化

田湾核电基地目前有4台WWER核电机组和两台M310改进型核电机组。为了降低待处置固体废物包产生量,满足废物最小化管理目标,田湾核电基地在从源头减少放射性废物的同时,建造了6台机组共用的放射性废物处理中心。采用烘干、超级压实和水泥固定工艺处理放射性废物,配合采用混凝土高完整性容器,在废物包满足近地表处置要求的前提下,各机组每年需要处置的废物量不超过50 m³。具有良好的经济效益和社会效益,对多堆核电厂址的废物最小化有一定的借鉴意义。

Waste minimization strategy for the Tianwan Nuclear Power Plant

There are currently four VVER nuclear power units and two improved M310 nuclear power units in the Tianwan Nuclear Power Plant. To reduce the final amount of solid waste package for disposal so to meet the waste minimization management objective, a radwaste treatment center was constructed and shared by the above six units in addition to taking measures to control the generation of radioactive wastes from sources. The radwastes are treated by drying, super-compaction and grouting process, together with adopting high integrity containers of concrete. Ascribing to the above measures, the waste volume to be disposed from one unit does not exceed 50 m³ each year under the precondition that the waste packages meet the requirements for near surface disposal. This waste treatment strategy brings good economic and social benefits, so can be used as a reference to waste minimization for nuclear power stations with multiple reactor units.
