Abstract
Human-computer interaction interface refers to a human-oriented, humanized and comfortable information display system. Building an interactive relationship with users in design is a bridge between users and information. The purpose of the human-computer interaction interface is to exert mutual influence between humans and machines, so that both parties understand each other’s information and keep the information exchange channel smooth. However, at present, there is a lack of visual human-computer interaction interface for lead reactor, and the results calculated by the thermal hydraulic calculation program cannot be presented directly to users. Moreover, it is very inconvenient for users to modify some parameters. Therefore, for the M2LFR-1000 lead-cooled fast reactor, this paper will introduce the development of a digital human-computer interaction platform based on the ICoCo concept and QT framework. The system code RELAP5 has been selected as the underlying thermo-hydraulic program. The platform can visually display the overall structure of the primary circuit of the M2LFR-1000, and can display parameters during calculation such as the inlet and outlet temperature of the primary circuit coolant in the core, the inlet and outlet temperature of the secondary circuit coolant in the main heat exchanger, and the mass flow of the core. The user can also adjust the parameters of the time-related components such as the inlet and outlet temperature of the secondary circuit coolant in the main heat exchanger when the calculation is being performed. In this way, the calculation of the thermal-hydraulic program can be synchronized with the display of the calculation results. At the same time, the user’s needs can be fed back to the thermal-hydraulic program in time. In addition, since QT is a cross-platform interface development software, the visual human-computer interaction interface developed by QT also has a good code compatibility, which is convenient for subsequent development and upgrade.
