Uranium dioxide powder - Determination of apparent density and tap density

active, Most Current
Organization: CEN
Publication Date: 1 February 2021
Status: active
Page Count: 16
ICS Code (Fissile materials and nuclear fuel technology): 27.120.30
scope:

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.
