Main Coolant Piping Welding of Lufeng Nuclear Power Unit 6 Successfully Completed

Main Coolant Piping Welding of Lufeng Nuclear Power Unit 6 Successfully Completed

On September 28, the main coolant piping welding of the nuclear island of Lufeng Nuclear Power Unit 6 was successfully completed. All non-destructive testing of the main coolant piping was finished, with the first-pass qualification rate of radiographic testing (RT)/ultrasonic testing (UT) reaching 100%, laying a solid foundation for subsequent key milestones such as nuclear loop flushing and cold functional testing. Facing the high standards of main coolant piping welding, the project department strictly implemented nuclear safety supervision and control requirements, carried out precondition verification across all dimensions of personnel, machines, materials, methods, and environment, established a main coolant piping welding control zone, strictly controlled the working environment including temperature, humidity, and cleanliness, and ensured stable and controllable welding conditions. The project team fully drew on the main coolant piping welding experience of Unit 5, formulated a special plan and implemented full-process management, and through digital monitoring means throughout the entire welding process, tracked key parameters such as welding deformation and temperature in real time, refined the process disclosure, in-process inspection, and quality acceptance procedures for each weld joint, and applied the work style of "strict, cautious, meticulous, and pragmatic" to every welding operation and every weld seam, ensuring the successful completion of the main coolant piping welding of Unit 6.

Chest CT Can Measure Bone Density and Warn of Brain Aging Risk: Latest Research Reveals Link Between Skeletal and Cognitive Decline

Chest CT Can Measure Bone Density and Warn of Brain Aging Risk: Latest Research Reveals Link Between Skeletal and Cognitive Decline

Chest computed tomography (CT), routinely used to screen for lung lesions, may hold important clues for assessing brain health. A research team from Johns Hopkins University in the United States explored approaches to using existing chest imaging to assess bone health and link it to brain aging, with the related findings published in September 2026 in the authoritative journal Radiology. The study showed that subjects with lower thoracic vertebral bone density experienced faster cognitive decline during subsequent follow-up, and specific white matter microstructural changes also showed associated degeneration. Chest CT is widely used in lung cancer screening and pulmonary nodule follow-up...
