Abstract: The main control room(MCR)is the monitoring and control center of nuclear power plant (NPP). MCR panel is one of the core components in MCR. Multiple operators monitoring sites are set up, including operator workstation, back-up panel, emergency control panel, etc. Under normal and accident conditions, operators need to monitor the operating conditions of NPP and control the operation of nuclear reactor through MCR panel. Virtual reality (VR) technology is introduced into the design of the MCR of NPP. The virtual MCR is built to demonstrate the initial effect and verify the human factors. Through using the advantages of VR technology, the design route of virtual MCR model is analyzed. Meanwhile, the application of VR technology in the MCR of NPP, as well as the fusion design of VR technology and digital twin technology in the MCR are proposed, which has a pivotal role late for the construction of the virtual MCR.
