The objective of this study is to investigate the stability characteristics for Kuosheng nuclear power plant (KNPP), which has two units of General Electric Company-designed boiling water reactor/6 with a rated core thermal power of 2,894 MW and a rated core flow of 3,832 {times} 10{sup 4} t/h. The approach to investigating the instability of KNPP has two steps. The first step includes three types of stability analysis: total plant stability, core reactivity stability, and channel hydrodynamic stability. The Electric Power Research Institute's methodology is adopted in this step. The second step is to establish the instability map under natural circulation conditions. This methodology is quite useful in identifying the stability safety margin and the setup of stability criteria during a nuclear reactor transient. In this study, the recirculation pump trip (RPT) transients with isolated feedwater heater were investigated and plotted on an instability map.
