Video inspection for inside and outside of control rod guide tube
Based on the practical requirements of nuclear power plants for wear measurement of control rod guide card and video inspection of screw locking cap,this paper proposed a corresponding video inspection scheme by analyzing the internal and external structures and inspection environment of control rod guide tube,developed a control rod guide card wear measurement device and a screw locking cap video inspection device,studied the machine vision measurement techniques of control rod guide card,and successfully applied it to the in-service inspection of nuclear power plants,directed the replacement of CRGT with severe wear.
