【摘要】 随着自主三代压水堆核电机型华龙一号（HPR1000）在国内外批量化建造，为了进一步提升HPR1000的安全性、经济性、先进性、运行可靠性、环境友好性和智能化水平，中国核工业集团有限公司于2019年开始启动HPR1000后续机型（AHPR1000）的研发，其中安全系统/设施的设计创新是研发核心内容。AHPR1000机型安全系统/设施主要用于在事故工况下保证反应堆的安全和控制/缓解放射性物质的释放。本文针对AHPR1000机型安全系统配置，提出“非能动+能动”的设计理念，从顶层安全理念及设计原则出发，重点对安全功能、安全配置、事故应对策略、试验验证等方面进行了介绍。更多还原

【Abstract】 With the batch construction of the independently developed third-generation pressurized water reactor nuclear power plant HPR1000 at home and abroad, China National Nuclear Corporation(CNNC) initiated the development of its follow-up reactor(AHPR1000) in 2019 to further enhance the safety, economy, advancement, operational reliability, environmental friendliness, and intelligence level of HPR1000. The design innovation of safety systems and facilities is a core part of this development. The safety systems and facilities of the AHPR1000 reactor are mainly used to ensure reactor safety and control/contain radioactive material releases under accident conditions. This paper proposes a design concept combining "passive and active" systems for the safety system configuration of AHPR1000. Starting from the top-level safety philosophy and design principles, it focuses on introducing the safety functions, safety configuration, accident response strategies, and experimental validation.更多还原
