Abstract:

In this research paper, the nonlinear dynamics of a modern CANadian Deuterium Uranium (CANDU) nuclear reactor called CANDU-6 is modeled in detailed with special emphasis on photo neutrons dynamics for the first time in CANDU reactor technology. A new strategy is adopted for global power control of modern CANadian Deuterium Uranium (CANDU) nuclear reactor called CANDU-6. Instead fourteen Multi-Input Multi-Output (MIMO) liquid zone controllers for reactor power control of CANDU-6 in fourteen zones, a Single-Input Single-Output (SISO) much simplified Proportional plus Integral plus Derivative (PID) Controller is designed using very fast convergence Nelder-Mead Algorithm (NMA) as benchmark controller based on CANDU-6 design specifications. The closed loop performance of CANDU-6 is further attempted and enhanced with Nonlinear Fuzzy Logic Controller (N-FLC) using Mamdani Inference Engine (MIE). The closed loop performance of both proposed new controllers are tested under normal and reactivity disturbance conditions and found highly remarkable and robust.
