This thesis aims at reproducing the real operating environment in nuclear power plants and indicating various products and equipment three-dimensionally by using virtual simulation technology and establishing an immersive virtual platform. This platform is highly immersive, which can make the related working personnel preserve the same reaction whether from the feel, operation or feedback from the action, and all these will be performed highly consistent with the actual power station. It can also carry on the analysis and verification of the designed equipment and conduct all kinds of virtual training to the related personnel. Hyper-simulation experience is infinitely close to the real environment. This platform has its unique advantages in aided design, maintenance verification, virtual training, and virtual display.
