To objectively determine layout priority sequence of element in human machine interface (HMI), and avoid the result difference induced in applying empirical method by different persons and keeping traceability of layout process, intelligent algorithm based on layout priority sequence for HMI was presented in this paper. With importance, operating frequency, operating sequence and reliability in ergonomics principles taken as parameters, the objective function model of layout priority sequence was made up based on ant colony algorithm. It was certificated in the main control room of a nuclear power plant, which layout priority sequence was acquired using the established objective function model. The experiment show that layout priority sequence deduced through the algorithm is a unique one. Its process is traceable, and it advantages than current methods.

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.

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.

The Human Machine Interface (HMI) of Monitor& Control System (MCS) is an important part of main control room in Nuclear Power Plants (NPP). The MCS is integrated by networks, digital computers and computer software. The paper discusses a new design mode for the HMI of MCS in Nuclear Power Plants. How to make the MCS information available is the focus of the HMI research. The paper discusses the design and research about the main layout and functions of the HMI. In order to verify and validate the design of HMI, the HMI of MCS is developed by a configuration software of JADE. HMI debugged with the NPP simulator. The Test illustrates that the HMI can help the operators to get very important information from MCS, which help the operators to operate the nuclear plant safely and reduces the human error.

In the past, the human machine interface is not computerized and the analysis tools are lack. So that most of previous researches of operator performance focused on the performance of individual operator rather than on the team performance. The relationships between team performance and individual performance are very close, but the team performance is not exactly equal to the sum of individual performance. The complexity of team performance evaluation is much higher than that of individual performance evaluation. Along with the development of new technology, especially the computerized technology, such as eye tracking tool and video recorder, team performance could be observed and measured. In NPP (Nuclear Power Plant), the operator performance of team work is closed to the safety of the whole plant. So the operators needed to be paid high attention to team performance. In order to improve the operator performance (including individual and team performance) base on the computerized human machine interface, this study bends to develop a real-time warning model for assessing team performance through the mental workload and human reliability evaluation. According to the analysis result, it could be as reference to modify the design about human machine interface in order to increase system safety and team performance of NPP.

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.

And Function

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.
