The fluctuations about the average in detector signals from a nuclear power plant contain information, about their origin and about the dynamic transmission properties of the reactor. Such fluctuations can be represented by noise descriptors, such as power spectral densities (PSD) and cross power spectral densities (CPSD), which display features, peaks and valleys, that are related to a specific causative mechanism such as fuel-assembly vibrations, core-barrel motion, thermal shield vibrations, pump vibrations, reactivity feedback effects and so on [1].
