摘要: 针对二代核电技术传统树脂取样方式存在的不足，介绍一种新型的核电厂树脂取样装置的结构与技术特点。本装置利用气动活塞原理，采用动密封技术，实现了对放射性树脂的远程自动取样功能。试验结果表明，该树脂取样装置取样精度高、重复性好，可使核电厂放射性废物取样系统更加精确、高效和安全。Abstract: In view of the defects in the traditional way of resin sample in the generation Ⅱ nuclear power plants, this paper introduces a new type of nuclear power plant resin sampler structure and technical characteristics. The pneumatic piston and dynamic seal technology are used in the device, and the remote automatic sampling radioactive resin function is adopted. Test results show that the resin sampler is with high sampling accuracy and good repeatability, and can make the nuclear radioactive waste sampling system more accurate, efficient and safe.
