Release of the Main Piping Welding Control Point for Unit 2 of Xudabao Nuclear Power Plant
Recently, the Northeast Regional Office of Nuclear and Radiation Safety Supervision under the Ministry of Ecology and Environment (hereinafter referred to as the Northeast Office) organized an inspection team to conduct an inspection at the main piping welding control point for Unit 2 of Xudabao Nuclear Power Plant. Experts from the East China Regional Office of Nuclear and Radiation Safety Supervision, the South China Regional Office of Nuclear and Radiation Safety Supervision, the Nuclear and Radiation Safety Center, the China Machinery Productivity Promotion Center, the Shanghai Nuclear Safety Review Center, the Suzhou Nuclear Safety Center, and other organizations participated in the inspection. As a critical component of the reactor coolant pressure boundary, the welding quality of the main piping is directly related to the construction quality and operational safety of the nuclear power unit. In strict accordance with relevant procedural requirements, the inspection team conducted a comprehensive inspection covering the implementation of the operating organization's quality assurance program, quality control of important items and activities, and preparation for main piping welding through on-site inspections, document reviews, and personnel interviews...

Main Piping and Surge Lines for Unit 2 of Xudabao Nuclear Power Plant Arrived at Site
On August 22, the main piping and surge lines for Unit 2 of Xudabao Nuclear Power Plant were successfully delivered to the site, laying a solid foundation for the commencement of main piping welding, a Level-1 milestone. The main piping serves as the aorta of the reactor coolant system. Together with the reactor pressure vessel, steam generators, and reactor coolant pumps, it forms a closed loop and pressure boundary. It is not only the core pipeline carrying the circulation and transfer of the reactor coolant but also a critical safety barrier for the nuclear island, making it an essential component of the nuclear island's core equipment. To ensure high-quality and on-time delivery of the equipment, Liaoning Nuclear Power took the lead in coordinating with the general contractor, procurement party, and equipment manufacturers, establishing a three-tier coordination mechanism of "daily reports + weekly meetings + monthly executive meetings" to fully streamline the information chain. Through measures such as optimizing production processes, mobilizing superior production capacity, and implementing continuous operations, all tasks were completed on schedule, ensuring the equipment was shipped and delivered to the site as planned.
