Seismic response of nuclear fuel assembly components
Original language description
The paper deals with mathematical modelling and computer simulation of the seismic deformation of nuclear fuel assembly components. The seismic excitation is given by two horizontal and one vertical synthetic accelerogram at the level of the reactor pressure vessel suspension in the reactor hall. The seismic vibration is investigated by numerical integration method in time domain in two phases - at the global reactor level and at the fuel assembly level. Seismic vibration of the nuclear fuel assembly is caused by spatial motion of the fuel assembly lower and head pieces fixed in the support plates of the reactor core. The modal synthesis method with DOF reduction is used for calculation of the fuel assembly component deformations. The presented method is applied for the Russian TVSA-T fuel assembly in the WWER 1000/320 type reactor core in NPP Temelín.
