基于虚拟现实的反应堆退役模拟研究

Research of Reactor Decommissioning Simulation Based on VR

反应堆退役工程是庞大的系统工程,需要进行退役作业的优化设计和技术评估。应用虚拟现实技术可以生成三维的虚拟堆环境,进行虚拟退役操作,从而为退役工程提供分析工具,为实施方案的确定、关键技术难点分析、退役数据信息管理和培训等提供依据和使用平台。该研究在分析退役工程有关需求的基础上,设计了基于虚拟现实的反应堆退役模拟系统,并针对其中场景构造、虚拟拆除、虚拟去污、虚拟剂量显示和虚拟作业等关键技术进行了讨论。在各项研究的基础上,针对具体应用,初步实现了应用系统。

Reactor decommissioning is a huge system engineering, which requires optimal design and effectiveness analysis. Using VR technology, a virtual 3D reactor can be constructed and be decommissioned without any danger. The simulation system based on VR provides analysis tools for decommissioning engineering, offers evidences for making decision and finding key problems of decommissioning, what＇s more, it can contribute to operation training and decommissioning datum management. After analyzing requirements of reactor engineering, a reactor decommissioning simulation system based on VR is designed, key VR techniques of this system such as scene construction, virtual dismantlement, virtual decontamination, radiation dose visualization and virtual operation are discussed. Depending on research results, a primary application system is realized according to one specific reactor decommissioning project.
