ABSTRACT

This paper presents a comprehensive assessment of the state-of-the-art in the analysis of two-phase flow instability mechanisms. Based on a boiling water nuclear reactor (BWN) system, detailed discussion is given to illustrate the behaviour of excursive instability, pressure drop oscillations, density wave oscillations, stability margins and non-linear stability.
