3-D virtual analysis system to analyze the motion of Control Rod Drive Mechanism (CRDM) was developed. The analysis system consists of 3-D model established per the actual dimensions and interfaces of CRDM parts and a routine to calculate forces acting on the mechanism, and was verified by mock-up test using equipment same to actual product. The analysis system is useful for functional evaluation in maintenance or to factor out root causes in case of malfunction of CRDM.
