Abstract

Abstract

Analysis of drop of spent fuel transfer equipment in nuclear power plant is the most stringent condition in overall structural safety analysis. In order to solve the problem of dynamic impact analysis and evaluation of equipment drop, the finite element analysis and simulation software LS-DYNA is used to numerically simulate the spent fuel transfer equipment, and model the drop of typical spent fuel transfer equipment. Combined with the actual plant site conditions, the drop contact ground adopts Holmquist-Johnson-Cook (HJC) model. Through simulation calculation, the acceleration curve of equipment and the deformation variables of key position are obtained. The results show that the deformation of the storage sleeve is greatly affected by the drop angle when combined with the actual ground conditions in the plant. The vertical drop of the equipment shall be avoided in the overshoot of storage and transportation. The analysis and evaluation method in this paper can provide technical support and theoretical basis for the autonomous design of spent fuel transfer equipment.
