The theoretical model of acoustic field calculation and interaction between field and defect is proposed based on Rayleigh Integration, Kirchhoff approximation, Geometrical theory of diffraction and Born approximation theory, and then the calculation and analysis system of ultrasonic testing(UT-CAS) is developed for the inspection of the key components in nuclear power plants. The application of UT-CAS is introduced by the modeling of the safe end bi-metallic weld inspection. UT-CAS can quickly and accurately model various inspection cases, and is helpful for the data analysis, performance demonstration and NDT training.
