First Backup Emergency Diesel Generator of Hualong One Officially Available at Sanao Nuclear Power Unit 2

On October 2, the first backup emergency diesel generator (9LHW) of Hualong One completed the replacement grid connection test at Sanao Nuclear Power Unit 2 and was officially put into service. The equipment can replace any one of the original 12 emergency diesel generators (EDGs) in Phase I and Phase II projects, significantly improving the redundancy, reliability, and maintenance flexibility of the plant's emergency power supply. Sanao Nuclear Power Phase I and Phase II each have 3 emergency busbars, with one EDG configured for each busbar. However, due to the absence of cross-power supply for loads, the preventive maintenance windows of the original units were concentrated, affecting the overhaul schedule. Since 2021, Cangnan Nuclear Power has promoted the project of adding backup diesel generators, improving from the design source, building a new backup emergency diesel generator building (BDD), and constructing corridors and cables connected to each unit...

First Application and Verification of Intelligent Monitoring and Adjustment System for Nuclear Power Plant Personnel Status at "Hualong One" Nuclear Power Plant

On September 4, CGN Engineering, in collaboration with Cangnan Nuclear Power, successfully completed the testing, verification, and on-site data collection of the Intelligent Monitoring and Adjustment System for Nuclear Power Plant Personnel Status at the San'ao Nuclear Power Base. The CGN Engineering departments participating in this testing and verification included CGN Design Institute, the National Key Laboratory of Nuclear Power Safety Technology and Equipment (hereinafter referred to as the National Key Laboratory), CGN Engineering Cangnan Project Department, and Huasheng Technology. This joint test marks an important milestone in the project's transition from technology research and development to engineering application, providing key technical support for the quantitative analysis transformation of human factors safety management in China's nuclear power industry. The system, built upon the personnel fatigue status monitoring principle prototype developed under the Intelligent Nuclear Power strategic special project, has been iteratively improved with continuous support from the Yangjiang Chuangbao High-tech Research Project and the National Key Laboratory research projects, and has now evolved into a mature product suitable for engineering and large-scale application. Previously, relevant functional modules of the system had been deployed and data collected in applications such as human factors verification in the main control room of Yangjiang Nuclear Power Base and simulator training at Taishan Nuclear Power Base. The on-site testing and data collection at the San'ao Nuclear Power Base further verified the system's environmental adaptability and reliability across multiple nuclear power base scenarios, laying a solid foundation for subsequent industry-wide promotion and application.

Module 4 of Steel Liner for Unit 3 of San'ao Nuclear Power Plant Successfully Hoisted

At 8:16 a.m. on August 15, the hoisting operation of Module 4 of the 3BRX steel liner for Unit 3 of the San'ao Nuclear Power Plant was officially launched. Under the stable operation of the 2,000-ton crawler crane of CNNC Machinery Engineering, the module successively completed a series of procedures including slewing, load-bearing travel, and alignment adjustment. After 220 minutes, the hoisting task was successfully completed. Module 4 of Unit 3 hoisted this time was integrally assembled from the fourth and fifth layers of the cylinder, with a diameter of approximately 45 meters and a height of 11.46 meters. The module features a large volume, susceptibility to deformation, and limited slewing space for the crane. The project team strictly implemented the special plan, completed site reinforcement, transport of baskets and counterweights, and crawler crane relocation in advance, organized hoisting simulation drills, and comprehensively inspected various safety hazards...
