Reactor dynamics is a branch of nuclear engineering that deals with the study of the dynamic behavior of nuclear reactors. This includes analyzing how reactors respond to changes in operating conditions, such as changes in reactor power levels, flow rates, or temperature. It also involves studying the stability and control of reactor systems to ensure safe and efficient operation. Reactor dynamics research aims to improve the design, operation, and safety of nuclear reactors by developing models and simulations to predict reactor behavior under different scenarios. This research area is crucial for understanding and mitigating potential reactor accidents and for optimizing reactor performance. Both theoretical and experimental studies are conducted in reactor dynamics to advance our knowledge of nuclear reactor systems.
