Abstract

Abstract

In order to study control rod dropping history under seismic conditions, based on the inertia resistance calculation method, viscous resistance calculation method and collision contact algorithm, the rod dropping history under seismic loads is calculated under the background of a reactor control rod drive line of the third generation nuclear power advanced R &D project. The seismic test of the 1:1 prototype of the reactor drive line is carried out on the multi-point excitation tester. The multi-frequency wave method is used to apply seismic loads at several related points between the drive line and the reactor, including operating basis earthquake (OBE) test and safe shutdown earthquake (SSE) test. The results show that the calculation curves of rod dropping time, rod displacement, velocity and acceleration are in good agreement with the test curves. Therefore, the research methods established in this study can provide necessary analysis methods for the safety analysis of nuclear power plants.
