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.

基于MATLAB、MATLAB- simulink和PCTRAN的六种反应堆(ACP100、VVER1200、NuScale、ESBWR、AP1000、ABWR)不同动态功能设计与分析及事故分析

不同的动力学函数可以描述核反应堆的各种行为。使用解析或数值解来解决这些功能耗费了时间，并且分散了对建模本身目标的注意力。本研究工作采用MATLAB软件的Simulink和MATLAB工具箱作为核反应堆行为研究的建模和编码平台。在MATLAB-Simulink环境下建立了系统传热模型、放射性核素衰变过程规律模型、氙中毒模型和钐中毒模型。本研究还对ACP100、VVER1200、NuScale、ESBWR、AP1000和ABWR 6种反应堆在运行工况下发生失冷剂事故时的不同参数进行了分析。利用PCTRAN (Personal Computer Transient Analyzer)软件进行了仿真。在此模拟中，与功率、压力、流量、反应性和温度变化相关的所有六种反应器都使用默认参数。分析表明，在反应堆动力运行过程中，由于功率、压力、流量、反应性和温度变化的影响，这些反应堆具有潜在的危险性。
