60Co-γ放射源倒装系统设计

The Design of Co-γ Radiation Source Inversion System

针对我国CO-60放射源倒装、退役过程中,传统方法进行放射源标号识别、倒装(望远镜、放大镜、机械夹具)存在过程繁琐、耗时长、效率低等问题,结合我国钴源装置即将大量退役的现状(放射源使用年限20年),本文采用自动化技术、辐射抗扰技术开发用于高剂量场水下环境,用于放射源倒装的自动化系统。该系统采用VisualC++开发上位机平台,可实现远程光学变焦及图像捕捉,以STM32单片机为主控芯片,设计了两套针对不同放置姿态放射源远程夹取机械手,该系统可协助工作人员快速准确完成放射源的倒装,有效提高放射源倒装的效率。

In view of the problems existing in the process of inversion and decommissioning of Co-60 radioactive source in China,the traditional methods of radioactive source label identification and inversion for the tedious process, long time-consuming and low efficiency,( telescope, magnifying glass and mechanical fixture) have problems of. Combined with the current situation that a large number of cobalt source devices are about to be decommissioned( the service life of radioactive source is 20 years), this paper adopts automation technology and radiation anti-iterference technology to develop high dose measurement field, underwater environment, automatic system for radioactive source inversion. The system uses Visual C + + to develop the upper computer platform, which can realize the remote optical zoom and image capture. With STM32 single-chip microcomputer as the main control chip, two sets of remote clamping manipulators are designed for different positions of radioactive sources. The system can help the staff to complete the inversion of radioactive sources quickly and accurately, and effectively improve the efficiency of the inversion of radioactive sources.
