Development of virtual reality-based simulation system for nuclear and radiation safety

How to reduce the radiation dose to worker is one of the focus problems of radiation protection research. Based on digital reactor and radiation virtual human technologies, a virtual reality-based simulation system for nuclear and radiation safety named SuperMC/RVIS2.3 was developed. The basic functions of SuperMC/RVIS2.3 include CAD-based modeling and virtual assembly simulation of complex components, visualized analysis of dynamical 3D radiation dose field coupled with geometry model, virtual roaming simulation and organic dose evaluation in radiation environment. SuperMC/RVIS2.3 was applied in the maintenance simulation of International Thermonuclear Experimental Reactor (ITER) poloidal field (PF) repair and target's maintenance scenario of China LEAd-based Research Reactor (CLEAR-I). The test result shows that the system makes it possible to safely perform work scenario designs and optimization, maintenance plan, emergency evaluation and operation training.
