Abstract
The paper deals with mathematical modelling and computer simulation of the seismic response of fuel assembly
components. The seismic response is investigated by numerical integration method in time domain. The seismic
excitation is given by two horizontal and one vertical synthetic accelerograms at the level of the pressure vessel
seating. Dynamic response of the hexagonal type nuclear fuel assembly is caused by spatial motion of the support
plates in the reactor core investigated on the reactor global model. The modal synthesis method with condensation
is used for calculation of the fuel assembly component displacements and speeds on the level of the spacer grid
cells.
