000012477 520__ $$2eng$$aIntegrity of the VVER reactors internals is the important requirement of the NPPs long term operation. Two possible methods how to meet these requirements are: non destructive evaluation and diagnostic of the mechanical vibrations. The second one method is in the next analyzed. As the sensors are obviously used accelerometers, pressure pulsation sensors, ex-core ionization chambers and self powered neutron detectors. The significant changes of the frequency spectra are supposed to be symptom of the integrity changes..
