en.Wedoany.com Reported - The final batch of components for the control rod drive mechanism of Unit 2 at the Xudapu Nuclear Power Plant—including coil assemblies and drive rod assemblies—arrived at the site on July 17.

Installed above the reactor pressure vessel head, the control rod drive mechanism is a core control device of the nuclear reactor. It drives the control rod assemblies to move precisely up and down within the reactor core and holds them at designated positions based on commands from the control and protection system. In the event of a power loss, it automatically releases the control rod assemblies, allowing them to rapidly insert into the core under gravity, thereby performing key functions such as reactor startup, power regulation, and power maintenance.

Through close coordination among all parties, the successful arrival of the final batch of control rod drive mechanism components for Unit 2 of the Xudapu Nuclear Power Plant has laid the foundation for the on-site integrated reactor head assembly work for Unit 2.

The smooth delivery of the control rod drive mechanism equipment for Unit 2 of the Xudapu Nuclear Power Plant is the result of close collaboration among all parties. These control rod drive mechanism components are a vital part of the nuclear reactor's core control equipment, and their arrival marks a new phase in the construction of Unit 2. Located in Liaoning Province, China, the Xudapu Nuclear Power Plant is one of the nuclear power projects under construction in the country.
