Group 1 - The United States remains the global leader in nuclear power generation with a total output of 781 billion kilowatt-hours, accounting for 18.9% of the national total generation, supported by an installed capacity of 96.95 gigawatts [1] - China ranks second with 58 operational units and a capacity of 60.88 gigawatts, but is significantly expanding its nuclear fleet with 27 units under construction, which raises concerns among Western observers [3] - The stagnation of nuclear power development in the U.S. is attributed to the high costs and long investment cycles associated with nuclear projects, as exemplified by the Vogtle units 3 and 4, which exceeded $30 billion in costs [3][5] Group 2 - China's nuclear expansion is driven by its strong industrial manufacturing capabilities, achieving a 100% localization rate for units like the Hualong One, reducing the unit cost to approximately 13,000 RMB per kilowatt [5] - The construction timeline for nuclear power plants in China has been shortened to 4 to 5 years, contrasting with the lengthy approval processes in the U.S. [5] - The operational efficiency of the aging U.S. nuclear fleet, with an average capacity factor exceeding 92%, highlights the effectiveness of asset management despite the age of the plants [5] Group 3 - The U.S. nuclear sector is shifting focus from large reactors to developing small modular reactors (SMRs), with projects like TerraPower's sodium-cooled fast reactor in Wyoming representing a strategic pivot [8] - While China has advantages in engineering, it faces challenges in original innovation and commercializing advanced nuclear technologies, such as high-temperature gas-cooled reactors and molten salt reactors [10] - The U.S. is forming exclusive nuclear supply chain alliances, which may pose risks for China, particularly regarding access to high-performance nuclear fuel and control chips amid geopolitical tensions [10][12]
