Abstract

Abstract

At present, the appearance inspection of spacer grid in China has always been manual visual inspection, which is low in inspection efficiency, easily leads to visual fatigue of inspectors, and even has the risk of false inspection and missed inspection. A set of automatic inspection device for the appearance of spacer grid is developed by using photoelectric, image acquisition and software processing technology, which realizes the automatic inspection of the appearance inspection items of spacer grid; improves the inspection level and efficiency of spacer grid, avoids the manual missed inspection as much as possible, and further reduces the risk of the operation of the reactor core fuel assembly. The inspection accuracy has reached the design goal. It has been successfully applied to the appearance inspection of spacer grid, running in good condition.
