The discovery of the atom and the subsequent development and utilization of nuclear energy have given a new impetus to the progress of humanity and greatly enhanced our ability to understand and shape the world. Yet nuclear energy has associated risks and challenges. To better utilize nuclear energy and achieve greater progress, we must properly respond to the challenges it poses and ensure nuclear safety.In the early days of the People's Republic of China, due to the requirement for national development, the Chinese government made a major decision to develop and utilize nuclear energy, officially launching its nuclear industry.Over the past 70 years, China's nuclear industry has grown from scratch,developed steadily, and formed a complete system, which has made an important contribution to ensuring energy security,protecting the environment, improving people's living stand-ards, and promoting high-quality economic development.Cluna has always regarded nuclear safety as an important nationalresponsibility, and integrated it into the entire process of nuclear energy development and utilization. It has always developed the nuclear industry subject to considerations of safety, imple-mented regulation in accordance with the strictest standards,and adapted to the new requirements of the nuclear industry.China's nuclear industry has always developed in line with the latest safety standards and maintained a good safety record,pursuing an innovation-driven path of nuclear safety with Chinese characteristics,Since the 18th National Congress of the Communist Party of China, China's nuclear industry has entered a new period of safe and efficient development. President Xi Jinping proposed a rational, coordinated and balanced nuclear safety strategy, placing equal emphasis on development and safety, and advocating building a community of shared future for global nuclear safety - he has pointed out the direction for China's nuclear safety for a new era, and provided the Chinese approach to international cooperation in the development and utilization of nuclear energy and to lasting global nuclear safety. Under the guidance of this strategy, China has gradually built a nuclear safety govemance system with legal norms, administrative regulation, industry self-discipline, technical support, personnel support, culturalguidance, public participation, and international cooperation as the pillars. The guarantee of nuclear safety is stronger.
