Core Viewpoint - The successful grid connection of the first "Hualong One" nuclear power unit in the Yangtze River Delta marks a significant step towards its official commissioning, contributing to the region's green and low-carbon transformation and supporting the booming demand for energy in the smart economy sector [2][4]. Group 1: Project Overview - The first unit of the Zhejiang San'ao Nuclear Power Project, which began construction on December 31, 2020, successfully connected to the grid on March 12, 2023, indicating its readiness to supply power to the grid [2][4]. - The project plans to construct a total of six "Hualong One" nuclear power units, with three already under construction [4]. Group 2: Energy Production and Environmental Impact - Once fully operational, the San'ao Nuclear Power Project is expected to generate over 54 billion kilowatt-hours annually, which is nearly equivalent to the total electricity consumption of Wenzhou City, serving the needs of over 5 million people [4]. - The project is projected to reduce standard coal consumption by over 16.35 million tons and lower carbon dioxide emissions by approximately 50 million tons each year, equivalent to the afforestation of over 120,000 hectares [4]. Group 3: Technological Advancements - The project has implemented a "smart construction site" approach, achieving visualization, automation, and intelligent management, which is expected to reduce manual labor by approximately 700,000 work hours annually [5]. - The first domestic intelligent management system for radiation film has been developed, achieving over 95% accuracy in defect detection and intelligent review during the installation phase [5]. - Innovative construction techniques, such as the modular assembly of detachable prefabricated wall components, have been applied, leading to significant cost savings and efficiency improvements in nuclear power engineering [5].
