Abstract

Stability and bifurcation analyses of a new natural circulation BWR model that allows local pressure dependence of water saturation enthalpy and includes fundamental and first azimuthal modes for neutronics are presented. Stability boundaries (SBs) and 7.5% oscillation curves (representing natures of bifurcation along SBs) are plotted in inlet subcooling - external reactivity parameter space. Stability and bifurcation analyses show that both in-phase and out-of-phase oscillations as well as supercritical and subcritical bifurcations can occur along the SBs. Results of numerical simulations agree with those of stability and bifurcation analyses. Effects of several design and operating parameters on the stability of a natural circulation BWR are also reported.
