Reactor Noise Analysis Recent Research Activities in Japan

Abstract

A review is presented on the recent research activities in Japan in the field of reactor noise analysis. It covers six selected areas : nonlinear stochastic theory and identification of nonlinearity in nuclear reactor dynamics, structural identification via reactor noise analysis, autoregressive model and contraction of information, knowledge-based support system for reactor noise analysis and diagnosis, reactor noise analysis benchmark tests and application of noise analysis to BWR plant diagnosis.
