Main control room simulator is widely used in design verification and operator training for nuclear power plant. The simulator needs to implement the arrangement, environment, human machine interface and function of main control room, which should be the same as much as possible. For designer, each type of reactor needs an individual simulator for design verification. As the number of unit increased, the simulator will consume a lot of space and difficult to reuse for other project. In addition, design verification for control room and I&C system need to start at the early stage of a project and is usually an iterative process with the design work. Build a control room facility for simulator needs a lot of time and is difficult to modify once constructed. To make the simulator more flexible and match the project schedule, virtual reality technology can be used to replace or extend traditional control room simulator with approximately the same arrangement, environment, human machine interface and function. In the full scope engineering simulator of HPR1000 unit, virtual reality control room interface has been designed as an extension of real control room implementation. The designer or operator can control and monitor the power plant in virtual reality environment, which just feels like real control room. It also can be used for other type of reactor by connecting to other simulator server and adding corresponding control room model in virtual reality software. With this preliminary application, control room simulator can be implemented in a short time and flexible for modification, which give designer more time and space for design verification and optimization. Once it applied in training simulator of nuclear power plant in future, it may provide a low cost and flexible option for operator training.

A design of human machine interface (HMI) has been developed to ensure the safety and availability of marine nuclear power plant (NPP) in China. The staffing arrangement and HMIs are different from current nuclear power plants. One control room is used to monitor and control the reactor, the secondary loop, and the electric system. Considering the digital control room style, the elements of the HMIs in the control room are the large display panels and control consoles. Considering the digital control room style, the elements of the HMIs in the control room are the large display panels and control consoles. Information accuracy and control efficacy are thought as the ultimate goal. It has extremely high safety by hardware control on the control panel. Display device refers to the part designs of NPP one. Eventually it can provide centrally the working condition of the device and system, the operating parameters of key equipment, accident. Dynamic and static displays are combined to reflect real-time condition of the system conveniently, accurately and reliably. The necessary safety operations and displays are set on the safety console of each reactor independently. The large display panels are designed as an overview of the whole marine plant, which consist of large screen displays, mimic displays and alarm tiles. This paper points out that what the main issues is to be dealt with in the computerized HMI design process. A task-oriented HMI design principle is used to the interfaces of marine reactors starting up.

In order to improve the effect of refueling training in nuclear power plant, the simulation system of refueling machine was designed and developed, combining the virtual reality technology with a real control console. The 3D virtual refueling environment of nuclear power plant was established by 3D modeling. Signals from touch screen and console are gathered by PLC and transmitted to PC graphics workstation, control the motion of virtual refueling machine, which realize the refueling operation simulation. The operation in failure modes was also realized in the system through the programming of failure database. The results show that the system runs normally and can simulate refueling operation in normal and abnormal modes, the training of refueling personnel is implemented effectively.

Recently Human Reliability Analysis (HRA) is becoming more important to the safety of nuclear power plant (NPP). As the reliability of the NPP equipments have been increased more higher, HRA should be developed in order to guarantee the better safety of NPP. By the collection of human performance about operators in main control room of NPP, especially in accident situation, it is very important to enhance the human reliability. This paper chooses Loss of Coolant Accident (LOCA) and Steam Generator Tube Rupture (SGTR) as the initiating events, and base on this, some loss of other equipment or system have been added. Then the process that the operators deal with the accidents has been recorded in the accident situation in order to get reasonable human performance data. After we analyzed all of these video by some tools such as eye tracking tool, some items have been found which are very important to the human reliability such as training level, operation task, human-machine interface, surrounding, team work, etc. According to the analysis of the human performance result, we have evaluated the computerized human machine interface. As a result, it also could be benefit to improve the design of NPP, specially the design of main control room.

A Computerized Operator Support System (COSS) is an operator assistive technology that aids operators in monitoring processes to detect off-normal conditions, diagnose plant faults, predict future plant states, recommend mitigation alternatives, and select appropriate mitigation actions. The COSS works in collaboration with an advanced prognostics system called PROAID. The COSS provides a human-machine interface to help operators maintain situation awareness and detect faults earlier than would be possible using conventional control room technologies at nuclear power plants. Here we describe a third-iteration of efforts to develop and validate the COSS. The COSS has now been implemented as a prototype system for a full-scope nuclear power plant simulator. To date, two studies involving three licensed reactor crews were conducted to evaluate the COSS. Here we capture insights into the development of COSS as well as operator feedback and future development guidance derived from the operator-in-the-loop simulator studies.

This paper presents a method of constructing a nuclear power plant in-service maintenance virtual simulation scene and virtual maintenance process. Taking air-baffles dismantling process of CAP1400 nuclear power plant for instance, this paper discusses ergonomics, space analysis, and time assessment based on virtual reality in the process of in-service maintenance. It demonstrates the advantage of using virtual reality technology to design and verify an in-service maintenance process of nuclear power plants compared to the conventional way.

It mainly discusses the application of virtual reality technology to the conical roof lifting for the AP1000 nuclear power plant. By choosing the sketch-up and AutoCAD soft-wares, this paper established the 3d models of the conical roof and the 2600T Lampson crane in the manner of parameter. Based on virtual construction theory, these 3 d models were used to implement the simulation tests for the whole lifting progress in virtual environment so as to obtain optimized construction scheme and to train crane operator. And also the optimum running track for the crane is provided by the analysis, and the most economical enlargement plan for the 2600T Lampson crane landing pad is also provided.
