dcterms:description
The paper deals with modelling of the hexagonal type nuclear fuel assembly vibration caused by kinematical excitation determined by motion of the support plates in the reactor core. The support plate motion is excited by pressure pulsations generated by circulation pumps in the main circulation loops. The cyclic and central symmetry of the system is advantageous for the fuel assembly decomposition into six identical revolved fuel rod segments, central tube and skeleton linked by several spacer grids in horizontal planes. The modal synthesis method with condensation of the fuel rod segments is used for determination of steady vibration.
