核设施退役虚拟仿真系统框架研究

摘要

Since nuclear facilities have strong radioactivity, the process of dismantling nuclear facilities has some characteristics of high risk and complex procedure. The virtual simulation system of nuclear facilities decommissioning based on virtual reality technology can provide an aiding tool for decommissioning project. This paper analyzed the research results of native and abroad relative fields and the demand for one specific decommissioning project, then some functions of the virtual simulation system modules were proposed. Furthermore, a systematic framework structure based on software development technique was developed, and the corresponding technologies were analyzed and discussed. Combined with the latest research results of computer hardware and software technologies, the cutting, blasting, and the radioactive fluid simulation technique were discussed. The analysis results show that a comprehensive virtual simulation for decommissioning process can be achieved even on the common personal computer. The experts point out the framework has feasibility.%退役核设施具有放射性,其退役过程危险且复杂,基于虚拟现实等技术的退役虚拟仿真系统可为退役工程提供辅助工具.本文在分析国内外研究成果的基础上,结合一专项退役工程的需求提出了该虚拟仿真系统的功能模块组成.基于软件开发技术进一步给出了系统的框架结构,并对各模块实现的相应技术进行了分析和探讨.分析中结合了计算机软硬件技术的最新研究成果,对退役中的切割、爆破、流体及放射性等的仿真技术进行了探讨.分析表明,基于普通个人计算机也可实现退役过程的全面虚拟仿真.经专家论证本方案具有可行性.
