This paper presents the results of simulations of the recent power oscillation incident at the LaSalle-2 Nuclear Power Plant using the BNL Plant Analyzer. The causes of the oscillation were investigated and the sensitivity of the oscillation to key parameters was studied. It is concluded that the observed power oscillation was caused by boiling instability (i.e., density wave oscillation) reinforced by the reactivity feedback in neutron kinetics, and that the density wave oscillation resulted from flow reduction due to recirculation pump trip and feedwater temperature reduction due to partial loss of feedwater heating capability as well as power peaking. 7 refs., 9 figs., 1 tab.
