It has been proposed that the fluctuations of the neutron current, called the current noise, can be used in addition to the scalar noise in reactor diagnostic problems. The possibility of the localization of a vibrating control rod pin in a pressuriz

Calculation of the neutron noise, induced by small amplitude vibrations of a strong absorber is a difficult task because the traditional linearisation technique cannot be applied. Two methods, based on two different representations of the absorber, w

A method is described by which the axial position of a control rod can be determined. The method is based on the influence of a partially inserted control rod on the axial flux profile. By measurin...

Diagnostics of core-barrel motion, and notably that of beam mode vibrations, has been usually performed by two distinct concepts. One strategy is to perform a qualitative analysis in the time domain, using descriptors such as vibration trajectory, pr

Detecting the vibration and impacting of neutron detectors in boiling water reactor cores is usually attempted from the detector signals. Two such indicators used or suggested earlier are the widening of the vibration peak in the detector noise auto-

A scintillating fiber detector has been developed and tested for use as a 14-MeV neutron sensor. The detector, designated an “Encapsulated Scintillating Fiber Detector (EFD)”, is composed of a parallel array of 0.5 × 0.5 × 15 mm BCF-12 plastic

Three different models of a moving (vibrating) reactor boundary in time-dependent diffusion theory are investigated. The models are: (a) a localized absorber of variable strength at the boundary (equivalent to a perturbational treatment); (b) a time-

A neutron noise-based technique for the localization of excessively vibrating control rods is elaborated upon in the previous three papers of this series. The method is based on the inversion of a formula that expresses the auto- and cross spectra of

In part I of this paper (Pazsit, 1996), the paradoxical phase behaviour of the point kinetic response of a reactor was discussed. Namely, the fact that for small, periodic reactivity perturbations, in the lower frequency part of the plateau region λ
