en.Wedoany.com Reported - CNNC Mechanical Engineering has completed the lifting and positioning of two waste resin storage tanks in the nuclear island building of Unit 3 at the San'ao Nuclear Power Plant, laying the foundation for the installation of the waste treatment system.

The two waste resin storage tanks lifted this time are cylindrical equipment, positioned 10 meters underground in a narrow working space. The equipment quality assurance level is Q3, classifying this as an ultra-high-risk project, imposing extremely high requirements on lifting precision and attitude control.

At 15:34, the lifting command was issued on site. The 2000-ton crawler crane and a 75-ton truck crane worked in coordination to turn and upright the equipment, after which the 2000-ton crawler crane took over as the sole main crane. Through a series of precise operations, the two waste resin storage tanks were smoothly lifted, accurately rotated, and steadily lowered. By 18:40, both pieces of equipment were safely positioned at their designated locations, with the entire process lasting 3 hours and 6 minutes. The lifting operation was stable, on-site safety control was rigorous, and construction quality fully met standards.

Waste resin storage tanks are core equipment of the nuclear power plant's waste treatment system, responsible for storing radioactive waste resin. They serve as a critical barrier ensuring the safe and stable operation of the nuclear power plant, and their lifting quality and installation accuracy directly affect the long-term reliable operation of the waste treatment system.
