基于全自动振动装管装置的核燃料棒芯块装管工艺及改进

Loading Technique for Nuclear Fuel Rod of UO_2 Pellets and Its Improvement Based on Automatic Vibrating Loading Bench

确定了全自动振动装管的振动频率等参数。由于全自动振动装管工艺易造成包壳管定位差、包壳管管口磨痕等缺陷,影响燃料棒的外观质量,通过对全自动振动装管装置及辅助工装的改进,特别是针对包壳管管口磨痕等缺陷进行了一系列的工艺优化及改进,解决了装管过程中的燃料棒表面磨痕问题,提高了全自动振动装管装置的稳定性和可靠性。

Vibration frequency parameters are determined. Automatic process is easy to cause the positioning error of cladding tube, the grinding marks on cladding tube end, and thus affect the surface quality of fuel rods. Fuel rods grinding problem have be solved through the improvement of the automatic vibrating loading bench and auxiliary equipment, especially for the grinding defects on cladding tube end. This improvement also increases the stability and reliability of the automatic vibrating loading bench.
