Eigenfrequency analysis of nuclear reactor with clearances Eigenfrequency analysis of nuclear reactor with clearances in couplings

Original language description

The discrete model of the nuclear WWER 1000 type reactor with side clearances in the tongue and groove couplings between the lower part of core barrel and reactor pressure vessel is derived and used for eigenfrequency analysis. A harmonic balance method in the first approximation is applied in iterative computation of the reactor eigenfrequency-displacement amplitude plots. For illustration, the plots of the most sensitive eigenfrequencies with respect to clearances are presented.
