A General Formulation of Neutron Noise for Fast Reactor Systems
… is developed in order to analyze zero-power neutron noise experiments in fast reactor systems. A generalized dispersion equation is combined with theoretical expressions for the experimentally measured power spectral density and variance-to-mean ratio which makes it possible to express these …

A reactor physics framework to detect anomalies in HTGR core
This dissertation extends the application of neutron noise analysis as a tool for detecting anomalies in High Temperature Gas-cooled Reactors (HTGRs). Neutron noise is defined as the fluctuations in the neutron detector signal caused by perturbations in a nuclear reactor. Neutron noise analysis is …

ΕΠΙΔΡΑΣΗ ΑΝΟΜΟΙΟΜΟΡΦΗΣ ΑΝΑΔΡΑΣΗΣ ΣΤΟ ΟΠΤΙΚΟ ΠΕΔΙΟ ΑΝΙΧΝΕΥΤΗ
… LAST BOILING AND PRESSURE FEEDBACK EFFECTS ON NEUTRON NOISE ARE INVESTIGATED. IT IS CONCLUDED THAT THE STRUCTURE OF NEUTRON NOISE COHERENCES ATLOW FREQUENCIES CAN BE EXPLAINED BY EITHER PRESSURE OR/AND BOILING FEEDBACK.

Limits on subcritical reactivity determination using rossi-alpha and related methods
The subcritical reactivity, ρ, of a neutron multiplying system is of interest to many factions of the nuclear community. The subcritical reactivity in a nuclear system can be inferred from measurements of the prompt neutron decay constant, α. Near critical, the reactivity is linearly proportional …
