摘要
本文阐述了反应堆工程退役工作的三大任务之一——去污问题.就去污的深度和内函而言,它分系统去污和拆除去污;就去污的机理而言,它可简化为化学去污、物理去污、电化学去污和物理化学联合去污四大类.同时介绍了去污之目的、主要的污染核素及其来源和污染的机理;系统去污和拆除去污工艺选择应分别考虑的基本因素、去污工艺选择和国内外去污实例等.
The decontamination is one of the three major tasks in nuclear reactor decommissioning. For the deepth and content it may divided into system decontamination and dismantling decontamination;there are four decontamination process,the chemical,the physical, the electrochemical and the commination of physial and chemical. The object of the decontaminatioen, the nuclide, the saurce and the principle of the decontaminatioen is introduced. The basical factor for the decontamination process selection of system decontaminatioen and dismantling decontamination are also intrduced,some example of decommissioning are presented.
