Resumo
This review is focused on the impurities determination in uranium nuclear fuel grade matrix with the use of
spectrometric methods. It is known that uranium is the major element and material for the sustainable use in
the nuclear energy. The optimized use of this technology involves the improvement of several processes to
power generation. With regard of fuel reliability, the chemical characterization combined with environmental protection is particularly important in the uranium production cycle or in the nuclear fuel cycle, subject to
an increasing number of international conventions and protocols. The performance of nuclear fuel in reactors
depends mainly on the chemical composition of its impurities and its estimation is important from the point
of view of neutron economy. Among the instrumental analytical techniques commonly used for the determination of elemental impurities in uranium compounds spectrometric techniques are commonly used, such
as; FAAS, GFAAS, ICP OES and ICP-MS. Usually, it is necessary in a previous uranium separation and
preconcentration of the impurities for elemental determination. Thus, the aim of this review is to give an
overview of the main process using sample preparation, separation and preconcentration of analytes for
the instrumental determination.
