为减少中国实验快堆设备检修期间各种放射性物质对人体的伤害及对环境的污染,需要对这些设备采取适当的除钠、去污清洗措施。根据中国实验快堆现状,结合快堆技术发达国家经验,对检修设备的去污清洗拟采用不同类型的去污剂、去污方法,主要工艺参数列于表1。 In order to reduce the harm of various radioactive substances to the human body and the pollution of the environment during the overhaul of the experimental fast reactor in China, appropriate measures for the removal of sodium and decontamination are required for these devices. According to the status quo of China’s experimental fast reactors, combined with the experience of developed countries in fast reactor technology, different types of detergents and decontamination methods are proposed for decontamination and cleaning of maintenance equipment. The main process parameters are listed in Table 1.
