Dynamic Monitoring of Nuclear Reactor Protection Shell

G. BOLDYEV, A. ZHIVAEV

Abstract


The paper presents results of nuclear reactor protective shell dynamic parameters evaluation for Novovoronezhskaya Nuclear Power Plant (NPP). In order to determine the dynamic parameters of the Protective Shell the Operation Modal Analysis (OMA) was applied. The measurements yielded the values of vibro-accelerations at Protective Shell points, located around the polar crane cantilever. In order to determine natural vibrations modes, the frequencies and damping coefficients an operations modal analysis was conducted with the help of ARTeMIS Extractor software. Obtained modal parameters will be used for further long-term monitoring of the reactor protective shell.
