摘要
核电厂设计的首要问题,就是要在正常工况或事故工况下,能把这些放射性物质严加控制,把对工作人员的照射减少到可接受的水平,确保工作人员与公众的安全。活性炭吸附是近几年发展起来的放射性气体处理工艺,具有安全性好、设备占用空间小、操作简单的特点,适于处理流量较小的放射性废气,该方法的发展和改进尚有很大空间。不同种类的活性炭对惰性气体的吸附能力相差很大,高性能的活性炭不仅可以延长惰性气体的滞留时间,改进处理效果,而且还可以减少活性炭的装填量,降低二次废物量。采用常温活性炭吸附床可以将压缩机放置在吸附床后面,进而减少压缩机运行检查维修操作人员吸收的剂量。
The primary problem of nuclear power plant design is that radioactive materials can be strictly controlled,to reduce staff exposure to acceptable levels,to ensure the safety of staff and the public in normal working conditions or accident conditions.Activated carbon adsorption is developed in a radioactive gas treatment process in recent years with good security,small equipment space and simple operation features,suitable for small to handle the traffic of radioactive waste.There is considerable room for improvement and development.Different types of activated carbon adsorption capacity of the inert gases vary widely;high-performance activated carbon can not only extend the residence time of inert gases,improve the treatment effect,but also can reduce the amount of activated carbon loading and reduce the amount of secondary waste.At room temperature using activated carbon adsorption bed,the compressor may be placed behind the adsorption bed,thereby reducing personnel absorbed dose in inspection,maintenance and operating of the compressor.
