Multibody analysis of the control assembly drop in the VVER 440/213 nuclear reactor
M. Hajžman, P. Polach
pages 86 - +12p., full text

Control assemblies used in nuclear reactors are commonly based on a certain motor driving a control rod composed of absorbers and fuel rods. They allow to control of a chain nuclear reaction in a reactor core. This paper is focused on the control assembly of the VVER 440/V213 nuclear reactor modelling and on the investigation of its dynamic response in the course of the drop and prescribed seismic excitation. The influences of the pressurized water have to be introduced in the MBS model because control rods are falling in a limited space and water resistance is not negligeable. Possible contacts of the falling control rod with adjoining structure are supposed. The multibody model including all special features was created in the alaska simulation toolbox.
