Nonlinear vibration of the nuclear reactor with clearances in core Nonlinear vibration of the nuclear reactor with clearances in core barrel couplings
Original language description
Vibration of the VVER-type reactors excited by coolant pressure pulsations produces impulse and friction contact forces in the key-groove couplings between the lower part of core barrel and the reactor pressure vessel.These forces are used for calculation of power and work of friction forces in the slipping contact surfaces and for their fretting wear prediction in dependence on the clearance values.The paper presents an original approach to mathematical modelling and simulation analysis of reactor nonlinear vibrations respecting friction-vibration interactions at all key-groove couplings with clearances.
