In order to simulate the impact of control rod assembly on upper grid plate of reactor core after emergency shutdown of offshore floating reactor, the structure size of upper grid plate was optimized. In this study, ADAMS simulation software was used to simulate the impact stress and strain of 50 mm and 100 mm thick upper grid plate with and without spring buffer at 0.5 m / s impact speed. Therefore, the thickness of the buffer plate on the grid can be reduced, and the simulation results show that the buffer plate can be optimized effectively.
