Successful Hoisting of Module 3 of the Passive Containment Cooling Water Tank for Unit 4 of Zhangzhou Nuclear Power Plant

On August 15, the hoisting of Module 3 of the passive containment cooling water tank in the reactor building of the nuclear island of Unit 4 at Zhangzhou Nuclear Power Plant was successfully completed, with the entire hoisting process being safe and quality-controlled.

The passive containment cooling water tank is an important component of the passive part of the containment cooling water injection system. With a total height of 22.02 meters, it features a non-uniform cross-section in an approximately fan-shaped structure and is planned as three integral modules. Module 3, hoisted this time, had a total lifting weight of approximately 132.8 tons and a height of 5.84 meters, and was positioned using a 2000-ton-class crawler crane.

As the crane slowly lifted the module, through a series of precise operations including hook lifting, boom slewing, crane traveling, and luffing, Module 3 was smoothly placed onto Module 2 of the passive containment cooling water tank, with the entire process being seamless, efficient, and orderly.

The construction team of the Zhangzhou Nuclear Power Plant project will continue to implement the requirements of the "Pursuing Excellence · Reform for Breakthrough" year, and steadily advance the subsequent construction of the Phase II project of Zhangzhou Nuclear Power Plant with a professional and rigorous attitude and refined management standards.
