本文介绍一种针对核工业废镭源源项情况研究建立的镭源整备技术,适用于固体密封源、液体或粉末源等各种形态镭源的整备。整备工艺流程包括不规则形状液体粉末源的重新包装和装管、固体密封镭源的装管、封焊、检漏等步骤,具有操作简单,安全可靠等特点。设计的封装管有三种规格,结构简单便于焊接操作;设计的屏蔽容器有两种类型,铅屏蔽容器适用于长期贮存,200 L水泥屏蔽桶适合于中低放处置场处置。经整备的镭源均可回取,便于将来进一步整备处理或处置。
This paper presents a preparation for the nuclear industry waste radium sources of research and development of radium source preparation technology for solid sealed source, liquid or powder source and other forms of preparation of radium. The preparation process includes the repacking and packing of the irregularly shaped liquid powder source, the process of tube packing, sealing and leak detection of the solid sealed radium source, and the like. The utility model has the characteristics of simple operation, safety and reliability. The design of the package tube has three kinds of specifications, the structure is simple and easy to weld operation; There are two types of design of the shield container, lead shield container for long-term storage, 200 L cement shield for disposal in low-lying disposal. After the preparation of the laser source can be retrieved, for future further rectification or disposal.
