Event-oriented programming used in the development of a research reactor control simulator

The development of a reactor control simulator is presented, which includes a numerical solution, based on the Runge-Kutta-Fehlberg method, or the point kinetics model or a TRIGA research nuclear reactor, a fuzzy algorithm for controlling the power, and a graphical interact that responds to different user commands and displays, numerically and graphically, the relevant closed loop system parameters. The user can modify, during simulation, the demanded power level to visualize the dynamic behavior of the reactor and the performance of the controller. The event-oriented programming characteristics of Visual Basic are used in the design. Under an open program structure, the user may test and analyze different control schemes.
