为了对氚安全包容系统中氚扩散数据的变化进行直观分析,实现氚扩散的计算数据在空间中的三维可视化,本文基于Unity3D引擎研发了氚安全包容三维虚拟仿真系统.本系统基于计算数据驱动粒子系统对氚的输运及泄漏扩散过程进行三维仿真,以中国聚变工程实验堆CFETR的排灰处理系统(TEP)作为案例,模拟了排灰处理系统中氚的输运及渗透扩散过程,对关键位置的渗透泄漏进行了可视化分析,验证了氚安全包容系统的安全性,为氚安全包容系统及氚的渗透泄漏研究提供了参考.

To intuitively analyze the variation of tritium diffusion data in the tritium safety containment system and realize the three-dimensional visualization of the calculated tritium diffusion data in space, this study developes a threedimensional virtual simulation system for tritium safety containment based on a Unity3D engine. This system carries out a three-dimensional simulation of the tritium transport, leakage, and diffusion process with a particle system driven by calculated data. The tritium transport, leakage, and diffusion process in the tokamak exhaust processing(TEP) system is simulated, with the TEP system of the China Fusion Engineering Testing Reactor(CFETR) as an example. Visual analysis is carried out on key positions of infiltration and leakage, verifying the security of the tritium safety containment system. This study serves as a reference for future research in tritium safety containment systems and tritium infiltration and leakage.
