The problem of stability of nuclear power plants
- 63 Downloads
This article presents an investigation of the stability of nuclear power plants, consisting of an aqueous reactor with a negative temperature coefficient of reactivity, a steam generator producing saturated steam, and a turbine. It is assumed that the system has only two regulators: a throttling regulator before the turbine and a regulator for maintaining a constant water level in the steam generator.
One-group kinetics equations are used and a single group of delayed neutrons is considered. The investigation was performed for small excitation parameters. Nonlinear equations are linearized. Conclusions with respect to plant stability are given.
