WWER 1000/320 reactor fuel dynamic behaviour in joint time frequency domain

Popis výsledku v původním jazyce

In the past many start-up and operational measurements of pressure vessel and internals vibrations of VVER 440/213 NPP Dukovany and VVER 1000/320 NPP Temelin reactor units have been performed. These measurements in the case of NPP Dukovany and NPP Temelin included pressure fluctuation sensors, accelerometers, ex-core ionisation chambers, self-powered neutron detectors, absolute and relative displacement sensors. The evaluating of changes in fuel assemblies dynamic behaviour is particularly needed and required. Self-power neutron detectors installed in reactor fuel assemblies can hold important information about vibration in spite of complex surrounding which is influencing signal output by many parameters. The paper deals with the analysis of availableset of NPP Temelin self-power neutron detectors. The influence of main circulating pump excitement forces is demonstrated in joint time frequency domain. The beat effects example for selected sensors set of NPP Dukovany is also given to
