Novel photo-neutron oriented dynamic modeling and synthesis of robust global power controllers for CANDU-6 nuclear reactor using modern optimization techniques

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. © pakistan academy of sciences.
