摘要：The paper presents implementation process of basic principle simulators of a nuclear reactor processes.Simulators are based on point-models of processes: kinetics of neutrons,heat generation and exchange,poisoning and burning-up nuclear fuel.Reference simulator was developed in MATLAB/Simulink without taking into account real-time operation.Second simulator was built using the toolbox xPC with hard real-time requirements.Functional decomposition of a nuclear reactor was performed and processes with different time scales were isolated.Simulation of each separated process in Raspberry PI computer with coordination mechanism among them led to a distributed soft real-time simulator.Idea of web-based simulator is also presented.The engine of the web-based simulator can be implemented on the server while the presentation of the state of the simulator and the prescription of parameters can be performed using a web browser.This allows simultaneous access to the simulator using different devices,including mobile as tablets, laptops and mobile phones.Compliance tests of simulators with reference simulator were conducted and the results proved the correctness of implementation.A review of the properties and potential applications of the various versions of developed simulators is presented.
