Core Viewpoint - During the National Day and Mid-Autumn Festival holiday, China achieved significant breakthroughs in various fields, showcasing its capabilities in advanced technologies and infrastructure development [1]. Group 1: Nuclear Fusion and Energy - The construction of China's nuclear fusion device BEST has made a key breakthrough with the successful installation of a 400-ton base, marking the full-scale construction of the 6,700-ton main unit [2]. - The device is expected to demonstrate nuclear fusion power generation internationally for the first time, with the goal of lighting the first lamp by 2030 [4]. Group 2: Renewable Energy - The world's first "dual-tower one machine" solar thermal energy storage power station has entered the final debugging phase and is about to begin full system trial operation [4]. - This power station consists of two 200-meter tall heat-absorbing towers and nearly 27,000 heliostats, capable of providing uninterrupted power supply for 24 hours once fully operational [6]. Group 3: Marine and Aerospace Developments - China's "Jiaolong" submersible achieved its first dive in the Arctic ice zone during the 15th Arctic Ocean scientific expedition [9]. - The third AG600 "Kunlong" amphibious aircraft has successfully completed its production test flight, marking a significant milestone in China's large civil aviation sector [11]. - The first-ever underwater collaborative operation between manned and unmanned submersibles was successfully completed in the Arctic region [12]. Group 4: Infrastructure and Shipping Innovations - The construction of the Qingnian Hub, a key component of the Western Land-Sea New Corridor, has made progress with the completion of the large-scale hoisting work [14]. - The project is currently in a critical phase and is expected to be completed and navigable by 2026 [16]. - China's first 10,000-ton pure electric intelligent sea vessel has successfully launched, marking a transition to zero-emission, pure electric container transportation along the coast [17][20].

Group 1 - The construction of China's nuclear fusion device BEST has officially commenced with the successful installation of a 400-ton base, which will support the main unit weighing approximately 6,700 tons, marking a significant milestone in this major national project [1] - The world's first "dual-tower one machine" solar thermal energy storage power station has entered the final debugging phase and is set for full system trial operation, featuring two 200-meter tall heat-absorbing towers and nearly 27,000 heliostats, capable of providing uninterrupted power for 24 hours once operational [3][5] - China's "Jiaolong" submersible achieved its first dive in the Arctic ice zone during the 15th Arctic Ocean scientific expedition, marking a significant achievement in deep-sea exploration [6] Group 2 - The third AG600 "Kunlong" amphibious aircraft has successfully completed assembly and production test flights, indicating progress in the production of this large civil water-land amphibious aircraft [9][12] - The construction of the Qingnian Hub's large gate for the Pinglu Canal, a key project in the Western Land-Sea New Corridor, has been completed, with the project entering a critical phase aimed for completion by 2026 [11][14] - The first domestically built 10,000-ton pure electric intelligent sea vessel has successfully launched, marking a significant step towards zero-emission, pure electric container transportation along China's coastal areas [14][16]
