Seismic Analysis Method considering refrigerant flow according to operating conditions of Nuclear power plant

摘要

The present invention relates to an earthquake analysis method of a reactor structure in consideration of the flow of coolant according to the operating conditions of the nuclear power plant, and more particularly, to improve the accuracy of the earthquake analysis model in consideration of the flow of coolant according to the operating state of the nuclear power plant, By deriving the displacement vector of, and adding the displacement vectors according to the analysis responses, and performing the final analysis according to the summed displacement vectors, the final stress value is derived, which significantly reduces the analysis load due to the fluid-structure linkage analysis. A method of seismic analysis of reactor structures with accuracy.
