The 3D visual scene adopts a modular approach. The virtual simulation training system consists of a three-dimensional model, a visual drive, process modelling, a digital simulation engine and visual experience equipment. Examples are a small pipe burst, the power operated relief valve remaining open by mistake, damage to the waste gas processing system, etc.

This establishes a three-dimensional virtual reality model of the primary loop and control system of a nuclear reactor, to intuitively reflect the structure and operating status of the primary loop and connect the virtual reality scene and the primary loop simulation.Ģ Mathematical modelling of dynamic operation of the PWR systemĪ dynamic model of a PWR comprises at least the following models: primary loop mean temperature neutron dynamics, temperature neutron interact dynamics, core fuel and coolant temperature power operation temperature zero power operation temperature steam generator and reactor control system.ģ Virtual simulation of operation control of PWR system It includes:ġ A virtual simulation system using virtual reality technology The nuclear power system virtual simulation training system architecture is shown in Figure 1. The real environment and virtual objects are superimposed in the same space in real time. At the same time, augmented reality technology enables operators to integrate real world information and virtual world information, to achieve a sensory experience ‘beyond reality’. To strengthen the sense of bringing physical objects into operation, physical objects are introduced into the system and they communicate with the simulation model through an Ethernet bus to result in a real device response. The system architecture is shown in Figure 1. Designing a virtual simulation systemĪ virtual simulation training system for a nuclear power plant can be established based on virtual reality, process modelling and visual experience equipment technology.
THREE D VIEWER PROFESSIONAL
The professional skills and operational abilities of operators and managers are improved by this training, so virtual simulation plays an important role in improving nuclear safety. It also provides a practical virtual simulation training system for plant operators. In nuclear power systems, virtual reality can help workers to plan, design and monitor reactors more easily and intuitively. Virtual reality is now widely used, in industries as diverse as medicine, interior design, industrial simulation, maintenance, automobile simulation and fields in energy including nuclear power. This can provide designers with quick analysis, verify working conditions and provide operators and engineers with various types of simulation training.
