A frequency analysis of the fluctuations of neutron sensor signals from a PWR gives a Power-Spectral-Density curve (PSD) showing one or more peaks. Analyses of the coherence and phases of signals from a pair of diametrically opposed ex-core neutron sensors, within the frequency ranges of the peaks, show coherence values approaching unity and phases of approximately 180/sup 0/. The work described had two aims: to increase the understanding of the nature of the signals in the PSD peak; and to attempt to reveal expected connections between parameters at frequencies outside the PSD peak.
