反应堆一回路去污配方及工艺参数研究

Research of cleaning reagent on decontamination and process parameters of primary loops of reactor

一回路系统在进行放射性清洗去污时,现广泛应用的方法为化学循环去污法。本文主要研究去污工艺中去污剂的主剂、侵蚀剂和缓蚀剂的比例,在线去污清洗时的清洗时间和清洗温度,并根据研究出的清洗工艺在实验室内应用金属挂片进行腐蚀性评价。

At present,the widely used method about primary loops system for radioactive decontamination cleaning is the chemical recycling of decontamination method. In this paper,we mainly researched the composition of the primary reagent、erosion reagent and corrosion reagent. And the test for the best cleaning time and temperature of online decontamination cleaning were done. According to the best cleaning reagent,to use metal bolt for corrosion resistance evaluation in the laboratory.
