Power and Temperature Control of Nuclear Power Plant Based on Transfer Function Matrix Method

The paper presents the simple and efficient analysis method of frequency-domain to control core power coolant temperature Nuclear Power Plants (NPPs). In order properly describe neutron kinetic thermal transmission NPPs, a one-dimensional dynamic model has been accomplished by using linearizing in time domain discretizing spatial domain, then transfer function matrix can be obtained through Laplace transform. Based on effective different system inputs: reactivity feed water mass flow, analyzed Nyquist method. On this basis, are presented, stability is proved frequency domain. proposed verified RELAP5 that confirm its performance.
