Design And Research Of Cobalt-60 Hot Cell Automatic Monitoring System

With the development and the application of the nuclear technology, the nuclear safety and the radiation safety receive more and more attention. The cobalt-60 hot cell was built to produce civil and medical cobalt bomb. It is the high radioactive place and its operation must be under control. This paper designed automatic monitoring system's control plan for cobalt-60 hot cell based on PLC and the industry configuration software, which not only improved the system's automation level, but also satisfied the hot cell's safety request.The automatic monitoring system introduced in this paper is based on the industry configuration software and the PLC, which adopts PLC advantages such as: simple application, high reliability, good at anti-electromagnetic, the environment adaptability, the function consummated, the mature labor control system, the correspondence conveniently, and the characteristics to realize long-distance real-time monitoring, as well as industry configuration software's formidable data-handling capacity and graph performance ability. And it realized those functions which are the monitoring data centralized management, the automatic control, the failure detection, the real-time warning etc. The system was guaranteed to work under a stable and safe environment.The cobalt-60 hot cell automatic monitoring system is hot cell's nerve center. Without which, the hot cell's operation cannot functions normally for the experiment and the production. The present paper introduced the control system equipment shaping, the PLC hardware system's disposition, respective supervisory system, the PLC software's design and superior machine configuration software's programming, and has suggested some measures and in the system anti-jamming. Have realized the hot cell movement self-supervisory and the control finally, obtained conveniently and friendly man-machine interaction contact surface, as well as the formidable data record, the fault analysis function, satisfied the systems operation request. Finally, the paper has also pondered on some of cobalt-60 hot cell's entire supervisory system's deficiencies, proposed a direction to the later improvement.
