This paper presents a theoretical transfer matrix method for the modal analysis of nuclear coolant pump, and base on certain similarity law, a scaled rotor system is designed so as to simulate the characteristics of the real nuclear coolant pump, especially the vibration characteristics. Following that, the finite element method is used to verify the accuracy of the above theoretical method since there are a few simplifications in theoretical method compared with the finite element method. Finally the natural vibration frequencies and vibration modes of both nuclear coolant pump and the designed scaled rotor system are attained, which have high similarity with each other, and which confirm the accuracy of the two methods that are used in this article.
