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.
