Design & Analysis of Different Dynamic Functions of Nuclear Reactor and Accident Analysis of Six types of Reactors (ACP100, VVER1200, NuScale, ESBWR, AP1000, ABWR) using MATLAB, MATLAB-SIMULINK and PCTRAN

Abstract

Different dynamic functions can describe the various nuclear reactor behaviors. Efforts expended to solve the functions using analytical or numerical solutions consume time and distract attention from the objectives of modeling itself. This research work presents the use of Simulink and MATLAB toolbox of MATLAB software as modeling and coding platform for the study of the nuclear reactor behaviors. The system models of heat transfer, law of radionuclide decay process, xenon poisoning and samarium poisoning are developed within the MATLAB-Simulink environment. An analysis of different parameters in case of the loss of coolant accident under running condition of six kinds of Reactors (ACP100, VVER1200, NuScale, ESBWR, AP1000 and ABWR) is also conducted in this research. The simulations are conducted by using the prototype Personal Computer Transient Analyzer (PCTRAN) software. In this simulation, the default parameters are used for all six types of reactors related to the power, pressure, flow level, reactivity and temperature change. This analysis shows the potential hazard of these reactors due to power, pressure, flow level, reactivity and temperature changing effect during reactor power operation.
