摘　　要：10MW高温气冷实验堆球形燃料元件的制造使用橡胶模具冷准等静压工艺。制造了44批,约20540个燃料元件。燃料元件的冷态性能符合设计指标,44批燃料元件的平均自由铀含量为4.57×10^(-5),正品率为99％。Cold quasi-isostatic molding with a silicon rubber die was used for manufacturing the spherical fuel elements of 10 MW high temperature gas-cooled reactor. 44 batches of fuel elements, about 20 540 of the fuel elements, were produced. The cold properties of the graphite matrix materials satisfies the design specifications. The mean free uranium fraction in spherical fuel element from 44 batches is 4. 57×10-5 , certified products is 99%.
