CAP1400堆内构件对中检测技术研究

摘要

对中检测是CAP1400堆内构件制造装配的关键检测技术，针对传统光学对中方法的检测结果易受环境和人眼观测误差影响，且作业时间受限等缺点，开发了激光垂准—CCD光靶数据采集处理的新型对中检测方法。通过专用试验平台进行对中比对试验，结果表明该方法测量精度高，成功避免了传统方法的缺点，为堆内构件制造及核电站现场安装提供了新的对中检测方法。%The alignment measurement is the key technology of CAP1400 reactor interal manufacturing and assembly. Traditional method using micrometer collimating telescope has high requirements on the operating environment, operation time. The system of Laser Vertical-CCD optical target data acquisition and processing is developed. The comparison tests made through the special test platform show that the method has high accuracy of measurement. The disadvantages of the traditional optical measurement is avoided. A new method for manufacturing and installation of reactor internal is gained.
