Design And Performance Analysis Of TMSR Simulation Platform Based On Cloud Computing Technology

In January 2011,the Chinese Academy of Sciences initiated the first batch of Strategic Priority Research Program.The Shanghai Institute of Applied Physics is responsible for the nuclear energy system of the Thorium-based Molten-Salt Reactor(TMSR),and the goal is to develop a fourth-generation reactor in about 20 years.The simulator(engineering simulator,training simulator)is an indispensable device for the design and operation of nuclear power plants.Similarly,The research and development of TMSR simulation technology is one of the important aspects of the TMSR nuclear energy system.Based on the TMSR nuclear energy system project,the TMSR simulation platform and the TMSR-SF1 engineering simulator project were investigated.The paper initially completed the design and function implementation of the TMSR cloud simulation platform.This work was a useful exploration of the technology upgrade of the TMSR simulation platformThis paper first investigated the development of nuclear power simulation technologies at home and abroad,analyzed the characteristics,service models,and key technologies of cloud computing,compared mainstream open source cloud computing management platforms,and proposed the construction of a TMSR cloud simulation platform.Then,the requirement analysis and functional architecture design of the TMSR cloud simulation platform are completed,and a hierarchical and modular system architecture of TMSR cloud simulation platform is proposed.This architecture is similar to the typical technical architecture of cloud computing.Then,build an OpenStack-based TMSR cloud simulation test platform.During the technical implementation process,the service architecture and code of the related components of OpenStack are studied in detail,which include the computing component(Nova),network component(Neutron),storage component(Cinder),identity component(Keystone),image component(Glance),dashboard component(Horizon),message queue(RabbitMQ)and database(Mariadb).The process of installation and configuration of the TMSR-SF1 engineering simulator is converted into image format files,including professional simulation software and its system environment,and these image files are independent and modular.Then,upload the image format file to the TMSR cloud simulation test platform.After experimental testing and analysis,the user can directly access various simulation services of the TMSR-SF1 engineering simulator system through a browser without installing any client software.At the same time,the simulation computing resources provided by the platform are modular,and each function module can be used independently or in combination.Through the modular management of simulation resources,users can easily create,modify,and delete individual function modules.In addition,this paper uses TMSR-SF1 power regulation test and scram protection test to verify that the simulation results of the same simulation software on the physical machine and the TMSR cloud simulation platform are the same.Compared with traditional deployment methods of simulation system,which based on distributed physical machine,TMSR cloud simulation test platform can provide users with more convenient and efficient simulation computing resources throughout the software software life cycle.Ensure that the simulation system can be deployed and rebuilt quickly and flexibly.
