Abstract: HPR1000 is an advanced pressurized water reactor developed by China National Nuclear Corporation (CNNC) with fully independent intellectual property rights. In this paper, the production process of HPR1000 are firstly introduced, and then the general technology features of reactor core and safety systems design are discussed, including reactor core neutronics design, thermal-hydraulics design, safety systems design, experiment verification and the continuously design improvement and optimization of HPR1000, etc. With the brand new advanced design philosophy and technology, the economy, flexibility and safety of HPR1000 nuclear power plant regarded as a third generation nuclear power technology are enhanced.
