标准摘要
[中文适用范围]: 本文件规定了测定自由流动二氧化铀 (UO2) 粉末表观密度和振实密度的方法,该粉末将用于制粒和烧结作为核燃料的 UO2 颗粒。 该方法可用于不同类型的 UO2 粉末,包括颗粒、颗粒、球体或其他种类的颗粒。 该方法也适用于其他燃料粉末,如 PuO2、ThO2 以及粉末混合物,如 UO2-PuO2 和 UO2-Gd2O3。 本文件基于使用流量计漏斗的原理(见 4.1)。 也可以使用其他测量装置,例如斯科特体积计。 [外文原描述]: This document specifies a method of determining the apparent density and tap density of free-flowing uranium dioxide (UO2) powder which will be used for pelleting and sintering of UO2 pellets as a nuclear fuel. This method can be used for different UO2 powder types including grains, granules, spheres or other kinds of particles. The method can also be applied to other fuel powders as PuO2, ThO2 and powder mixtures as UO2-PuO2 and UO2-Gd2O3. This document is based on the principle of using a flowmeter funnel (see 4.1). Other measurement apparatus, such as a Scott volumeter, can also be used.
