Design and Implementation of a Fuzzy Logic Controller for the Pressurized Water Power Reactor Control

ABSTRACT The pressurized water reactor type power plant has a sophisticated automatic control systems. On the primary side, The Control rod system and the Soluble boron control the core neutron flux. On the secondary side, output steam is controlled by the turbine control valve and steam dump system. During the automatic control mode, the two sides work in a synchronized way so that transition to stabilized conditions will be achieved smoothly. This paper presents a detailed nuclear power model for the medium-term and long-term power system stability. This model can be used to analyze the difference transient fault on electrical grid. Also this work introduces the effect of utilizing the Fuzzy logic control methodology in the power control model of the PWR (pressurized water reactor). The fuzzy logic controller was tested on a PWR model using the Matlab Simulink Interface. Two case studies were performed on the model using both the fuzzy logic method and the traditional rod speed program for controlling the nuclear power plant variables. The proposed controller presented a higher performance than that of the traditional rod speed program controller.
