Simulation of Automated Controller System for Controlling TRIGA Mark -II Research Reactor

The TRIGA Mark-II Research Reactor of Bangladesh Atomic Energy Commission (BAEC) is the only nuclear reactor of Bangladesh. Presently power level variation of this reactor is done by manual movement control of the control rods by the operator, which is a manual and time consuming process. Here, according to the input by the operators to make the reactor critical at a definite power, the system would automatically move the control rods to positions (upper or lower) to attain the desired power level. Microcontroller based simple electronic circuit is used to control reactor power level. The target of this research is to design a simulation based system for TRIGA Mark-II Research Reactor of BAEC to vary the power level by automatic movement control of the control rods. By controlling the control rod positions reactor power level can be controlled easily. A separate power measurement system measures reactor power levels which would compensate the power level variation due to reactor poisoning. The overall system seems to be more safe, reliable, efficient and cost effective than the old manual system. Considering all this aspects, this design could be effective for the developing countries like Bangladesh. In this project only simulation is done by Proteus software, which is perfectly succeeded. In future this project can be implemented in hardware.
