摘要
为适应国家对核电厂放射性流出物排放的新要求,在分析AP1000反应堆放射性废液来源与特性的基础上,确定了内陆AP1000核电厂废液处理系统的改进原则。在对比不同改进工艺的优缺点后,提出采用化学絮凝,增设离子交换床和使用大孔树脂等手段对废液处理系统进行改进的方案,并对改进方案进行了性能验证。试验实例表明,改进后的废液处理系统能够满足内陆AP1000核电厂放射性废液排放的需求。
In order to satisfy the new Chinese standard of effluent water drained from nuclear power plant, the improvement principle of radioactive waste liquid processing system in AP1000 inland nuclear power plant was determined, based on the analysis of the sources and characteristics of radioactive waste liquid produced by API000 reactor. Several improving measures such as adopting chemical flocculation, adding ion exchange beds and using macroporous ion exchange resins were developed based on the advantages and disadvantages comparison of several process programs. Demonstration tests were carried out and the results showed that the improved process could meet with the requirement of radioactive waste liquid processing system in inland AP1000 nuclear power plant.
