CB20 structural module of Lianjiang Nuclear Power Unit 1 successfully hoisted into place

On October 23, the CB20 structural module of Lianjiang Nuclear Power Unit 1 was successfully hoisted into place, creating favorable conditions for subsequent mainline construction. This marks the completion of all heavy-lift tasks for the unit's main construction, and the project has fully entered the installation and commissioning phase. The CB20 structural module is a core component of the CAP1000 nuclear power passive containment cooling system. It consists of inner and outer cylindrical wall panels, a top plate, and a conical bottom plate, and is located atop the nuclear island shield building. The module is massive in scale and features a thin-walled annular structure, making it prone to deformation from uneven forces during hoisting, with high precision requirements for positioning and alignment. To ensure the successful completion of this milestone, the Lianjiang Project Department adhered to Party building leadership and established a Party member vanguard team for equipment and module installation. With a work attitude of "safety first, quality foremost," they coordinated and planned construction tasks, meticulously organized hoisting work, and through special progress meetings focused on key difficulties such as module deformation control and hazard elimination. They adopted multiple advanced technologies including 3D scanning interference analysis, BIM modeling to avoid conflicts, and wireless force measurement systems for real-time leveling of hoisting slings, ensuring the entire hoisting process was safe, orderly, and controllable.

Taishan Nuclear Power Achieves Full-Process Digitalization for Two Major Environmental Monitoring Inspections

Recently, the central station inspections of the Plant Environment and Meteorological Monitoring System (KRS) and the Hydrological and Water Quality Monitoring System (YSI) buoy inspections at Taishan Nuclear Power Plant have officially entered full-process digital operation, with all related inspection tasks integrated into the GFIS (Taishan Inspection Data Monitoring System) for online workflow, marking the end of the paper-based inspection sheet era. In the central station equipment room of the environmental laboratory, inspectors can complete online data entry and upload via mobile office devices after verifying data accuracy. △Inspection interface Previously, these two inspection tasks relied on paper-based recording, with inspection data manually transcribed on site and handed over offline for review, making real-time verification and sharing of information impossible. The mountains of paper forms not only made data retrieval time-consuming and laborious but also hindered equipment operation and maintenance quality assessments. Driven by the company's digital transformation initiative, these two inspection tasks have now embarked on the path of digitalization.
