摘　　要：10MW高温气冷实验模块堆球形燃料元件的制造技术的研究始于1986年。球形燃料元件的制造使用橡胶模具冷准等静压工艺。目前已完成了制造技术和石墨基体材料的研究和最佳化。已生产了25批,约11000个燃料元件。石墨基体材料的冷态性能符合设计指标,25批燃料元件的平均自由铀含量为5×10-5。R and D on the fabrication technology of the spherical fuel elements for the 10 MW HTR Test Module (HTR-10) began from 1986. Cold quasi-isostatic molding with a silicon rubber die is used for manufacturing the spherical fuel elements. The fabrication technology and the graphite matrix materials were investigated and optimized. Twenty five batches of fuel elements, about 11000 of the fuel elements, have been produced. The cold properties of the graphite matrix materials satisfied the design specifications. The mean free uranium fraction of 25 batches was 5&middot10-5.
