Development of a small-scale simulator for designing advanced control algorithms at nuclear power plants

There has been a difficulty in implementing control algorithms (including even proportional- integral-derivative control algorithms) designed to verify and test to many small-scale simulators. In particular, it was almost impossible to implement advanced control algorithms to them. Therefore, it is required to develop a new simulator that facilitates the implementation of advanced control algorithms and the interface between different kinds of application programs. The objective of this work is to improve the existing small-scale simulator (FISA-2/WS) for the Kori unit 2 nuclear power plant and thus enable advanced control algorithms to be tested and verified by being applied to it. The developed simulator consists of FORTRAN, Visual C++, and MATLAB programs and an advanced control method using a receding horizon control method was applied to it to control the steam generator water level
