Investigation of falling control rods in deformed guiding tubes in nuclear reactors using multibody approaches
Original language description
One of the interesting applications of multibody dynamics is the analysis of control assemblies or control rods used for the nuclear reaction control and emergency stops. Generally, control assemblies can be simplified to the typical problem of a long thin rod moving through guide tubes and driven by a motor. Two different approaches to the modelling of control assemblies for nuclear reactors are introduced in this paper. The first approach is based on the usage of a complex multibody model consisting of rigid bodies while the second approach employs the absolute nodal coordinate formulation. Both models are used for numerical simulations of falling control rods in deformed guiding tubes during the emergency reactor shut-down.
