总部位于深圳的中国广核集团有限公司通报，12月16日，我国具有自主知识产权的核电站应急柴油发电机组——“核柴一号”正式发布，多项核心性能指标、可靠性指标达到国际先进水平。

Shenzhen-based China General Nuclear Power Group Co., Ltd. reported that on December 16, China's nuclear power plant emergency diesel generator set with independent intellectual property rights - "nuclear Chai No. 1" was officially released, and a number of core performance indicators and reliability indicators reached the international advanced level.

  核电应急柴油发电机组是核电站应急供电系统的“最后一道防线”，其系统功能是在主电源和辅助电源失效时启动，向安全设备提供应急电力，以确保反应堆安全停堆，对保障核安全发挥着至关重要的作用。从二十年前的整机国外进口，到后来国外专利授权制造，国内一直没有核电应急柴油发电机组自主化机型。突破关键核心技术，研发具有自主知识产权的核电应急柴油机迫在眉睫。

       The nuclear power emergency diesel generator set is the "last line of defense" of the nuclear power plant emergency power supply system. Its system function is to start when the main power supply and auxiliary power supply fail, and provide emergency power to the safety equipment to ensure the safe shutdown of the reactor, which plays a vital role in ensuring nuclear safety. From the whole machine imported from abroad 20 years ago, to the later foreign patent authorization manufacturing, there has been no domestic nuclear power emergency diesel generator set autonomous models. It is urgent to break through key core technologies and develop nuclear emergency diesel engines with independent intellectual property rights.

  2021年，中广核工程有限公司牵头启动核电应急柴油发电机组自主化研发，积极整合数十家上下游供应链企业优势资源开展创新攻关，相继完成18项重大技术改进，解决了128项关键技术问题，研发过程中形成了26项技术专利，完成了1000小时可靠性试验，实现我国核电应急柴油发电机组“核柴一号”的自主研发。“核柴一号”具备启动快速可靠、平均无故障时间大于2000小时、平均修复时间小于10小时、集成化和智能化程度高等特点。（记者王丰）

       In 2021, CGN led the independent research and development of nuclear power emergency diesel generator sets, actively integrated the superior resources of dozens of upstream and downstream supply chain enterprises to carry out innovation research, successively completed 18 major technological improvements, solved 128 key technical problems, formed 26 technical patents during the research and development process, and completed 1,000 hours of reliability tests. Realize the independent research and development of China's nuclear power emergency diesel generator set "nuclear Chai No. 1". "Nuclear Chai No. 1" has the characteristics of fast and reliable start-up, average trouble-free time greater than 2000 hours, average repair time less than 10 hours, integration and high degree of intelligence.
