Development of HPR1000 Reactor Core and Primary Circuit

HPR1000 reactor core and primary loop is a third generation PWR system designed by Nuclear Power Institute of China (NPIC) based on the experiences of research, design, manufacture, construction and operation of existing pressurized water reactor power plants, and the experience feedback from Fukushima nuclear accident, and considering the preeminent design concept of world-wide advanced nuclear power plants. The reactor core and primary circuit is the core system and engine of HPR1000. This paper presents the design process of HPR1000 reactor core and primary circuit in NPIC based on '177 core'. The design of reactor core, primary circuit and equipment, and experimental verification are introduced to show the advancement, economy, and safety of HPR1000. (authors)
