In nuclear power engineering, the quality requirements for concrete are extremely stringent. Concrete structures must exhibit high durability to withstand the effects of nuclear radiation, chemical corrosion, and environmental changes. In particular, nuclear power projects impose higher design standards and safety requirements regarding concrete density. Traditional manual vibration and visual inspection methods are difficult to ensure the required level of concrete compaction. This paper presents an intelligent vibration technology for concrete in nuclear power engineering to enhance construction quality and efficiency. By integrating intelligent sensors, control systems, and data processing algorithms, the technology enables real-time monitoring and evaluation of the vibration process. Results show that intelligent vibration technology effectively ensures the density and uniformity of concrete in nuclear power engineering, thereby improving structural safety and reliability.
