Core Viewpoint - The construction of the No. 2 unit of the Guangdong Lufeng Nuclear Power Project has officially commenced with the first concrete pouring, marking the start of the main engineering phase for this unit [1]. Group 1: Project Overview - The Guangdong Lufeng Nuclear Power Project is located in Shanwei City, Guangdong Province, and plans to build six 1,000 MW pressurized water reactor units [1]. - The total volume of concrete poured for the No. 2 unit is approximately 6,635 cubic meters, with the pouring process lasting about 64 hours [1]. Group 2: Project Progress - The overall construction of the Lufeng Nuclear Power Project is progressing smoothly, with the No. 1 unit entering the peak phase of main engineering construction, while units 5 and 6 have fully entered the equipment installation stage [3]. - Once all six units are completed, the project will provide stable and reliable clean energy to support the economic development of the Guangdong-Hong Kong-Macao Greater Bay Area [3]. Group 3: Construction Technology - The No. 2 unit of the Lufeng Nuclear Power Project employs modular construction technology, which involves factory prefabrication and on-site assembly, significantly reducing on-site workload while improving construction efficiency and quality [4].

Core Viewpoint - The Guangdong Lufeng Nuclear Power Project's Unit 2 has officially commenced construction with the completion of the first concrete pour for the nuclear island, marking a significant milestone for China General Nuclear Power Group (CGN) [1][3]. Group 1: Project Details - The total volume of concrete poured for the nuclear island is approximately 6,635 cubic meters, with the pouring process lasting about 64 hours [1][3]. - The Lufeng Nuclear Power Project is planned to construct six million-kilowatt pressurized water reactor units, with four units already approved for construction [1][3]. Group 2: Construction Techniques - The construction of Unit 2 will leverage experiences from previous projects and promote the use of new processes, tools, and materials [3]. - The project employs modular construction techniques that utilize factory prefabrication and on-site assembly, enhancing engineering precision, quality management, and efficiency while reducing on-site operational risks [3]. - Advanced technologies such as BIM (Building Information Modeling), 3D scanning, and digital simulation are integrated to optimize construction plans and enable comprehensive visual management throughout the process [3]. Group 3: Smart Construction - The project aims to create a "smart construction site" by utilizing cutting-edge technologies like 5G networks, cloud computing, big data, and the Internet of Things for real-time intelligent monitoring and management of core elements such as personnel, machinery, materials, methods, and environment [3]. Group 4: Overall Progress - The overall construction of the Lufeng Nuclear Power Project is progressing smoothly, with Unit 1 already at its peak construction phase, while Units 5 and 6 have completed dome lifting and are fully engaged in equipment installation [3]. - In addition to the Lufeng project, CGN plans to start construction on five new nuclear power units by 2025, including units in Shandong, Zhejiang, and Fujian [3].
