Název v původním jazyce

Dynamic response of nuclear fuel assembly excited by pressure pulsation

Popis výsledku v původním jazyce

The paper deals with dynamic load calculation of the hexagonal type nuclear fuel assembly caused by spatial motion of the support plates in the reactor core. The support plate motion is excited by pressure pulsations generated by main circulation pumps in the coolant loops of the primary circuit of the nuclear power plant. Slightly different pumps revolutions are the cause the beat vibrations which causes an amplification of fuel assembly component dynamic deformations and fuel rods coating abrasion. The modal synthesis method with condensation of the fuel segments is used for calculation of the normal and friction forces transmitted between fuel rods and spacer grids cells.
