反应堆退役废金属高压水去污废水的再利用

用高压水射流去污将反应堆退役废金属再循环再利用,会产生相当数量的放射性废水。为了节省放射性废水处理费用并减少清水的消耗量,降低废金属去污的成本,应将这部分放射性废水回用。高压水去污废水中的放射性主要来自其中的固体颗粒。因此回用废水就要将水中固体颗粒去除。研究分析了各种可能的工艺,经过代价利益分析,选用了离心分离工艺。

Reuse of Waste Water from High Pressure Water Jet Decontamination for Reactor Decommissioning Scrap Metal

For recycle and reuse of reactor decommissioning scrap metal by high pressure water jet decontamination,large quantity of radioactive waste water will be generated.To save the cost of radioactive waste water treatment and to reduce the cost of the scrap decontamination,this part of radioactive waste water should be reused.Most of the radioactivities in the decontamination waste water come from the solid particle in the water.Thus to reuse the waste water,the solid particle in the water should be removed.Different possible treatment technologies have been investigated.By cost benefit analysis the centrifugal separation technology is selected.
