The determination of the bulk density of irradiated samples using a mercury pyknometer

Creators

Description

A method for determining the bulk density of fragmented UO2 specimens in the mass range 1 to 10 g by mercury pyknometry has been developed. The factor limiting the accuracy of the technique in this application is the consistency with which the pyknometer can be filled with mercury; this is dependent on the vacuum obtained in the pyknometer prior to filling. It has been found that this method can be used to determine the density of fragments of UO2 in the mass range specified to an accuracy of better than +- 0.2% (1σ). (author)
