HPI(SH:600011) Yang Shi Wang·2025-10-29 14:15Core Viewpoint - The Shidao Bay High-Temperature Gas-Cooled Reactor Demonstration Project represents a significant advancement in China's nuclear power technology, marking the country's transition from following to leading in the global nuclear energy sector [1][19]. Group 1: Project Overview - The Shidao Bay High-Temperature Gas-Cooled Reactor is the world's first commercially operational fourth-generation nuclear power plant, having commenced operations at the end of 2023 and achieving nearly 10,000 hours of safe and stable operation [3][19]. - The project is characterized by its inherent safety features, which allow the reactor to maintain safety without human or mechanical intervention during severe accidents [5][11]. Group 2: Technological Innovations - The reactor utilizes high-temperature spherical fuel elements instead of traditional fuel rods, with each reactor containing 430,000 fuel balls [7][9]. - The fuel balls are designed to withstand temperatures exceeding 1,620°C without releasing significant radioactive materials, ensuring high-temperature operation [9][11]. - The cooling system employs inert helium gas rather than water, contributing to the reactor's inherent safety [11]. Group 3: Development Process - The project began in the 1980s, with significant milestones including the establishment of a 10 MW high-temperature gas-cooled experimental reactor in 2000 and the official start of the demonstration project in December 2012 [13][15]. - A collaborative effort involving multiple universities, state-owned enterprises, and private companies has been crucial in overcoming numerous engineering challenges [19]. Group 4: Industry Impact - The project has led to the development of over 15,000 pieces of equipment, with 2,200 being first-of-their-kind and a 93.4% domestic production rate [19]. - The success of the Shidao Bay project is seen as a reflection of China's advancements in nuclear technology and its ability to innovate independently, positioning the country as a leader in the global nuclear energy landscape [19].
