Study On Network-Based Simulation System For High Temperature Gas-Cooled Test Reactor

The 10MW high temperature gas-cooled test module reactor (HTR-10), as one of the most advanced reactors for use in the 21st century, was designed and constructed by the Institute of Nuclear Energy Technology (INET) of Tsinghua University in China, and it has successfully reached full power level at the beginning of year 2003. The HTR-10 has the inherent safety feature of the HTR-Module reactor. The experience on design, construction and operation of the HTR-10 is essential to the future commercialization of the modular HTR. But researches on engineering simulating system of HTR are just beginning, and there are no sufficient references about their dynamic properties and control design. Therefore, the development of a system for simulation, control design and online support for HTR is very important for HTR.Based on the investigation of the technological status and research trends of nuclear power plant simulators in the world, a network-based simulator system for the HTR-10 was designed and developed, with the technology of the last nuclear power plant simulation and the idea of distribution. This system, as a subsystem of the simulation, control design and online assistant system for the HTR-10, runs on the MS Windows operation system. It has user-friendly Man-Machine Interface and good expansibility.As the main target of this thesis, a lot of technological problems have been successfully solved during development of a simulation based on network. The system adopts the Client-Server module, thereby, a robust calculation server was developed for the simulation calculating and network message sending and receiving. All clients can receive the message from the server, and some of them can send back control message to control the server. A simple protocol was developed to meet requirements of the data communication between the server and the clients. According to the existing HTR-10 main control room and the human factor engineering, user-friendly Man-Machine Interface was developed with the new graphics and software development technology.This system is not only very helpful to the design, operation and training of the HTR-10, its construction method is also useful to the simulation system design of other types of nuclear power plants.
