Resumo
The fuel of type MTR: U3Si2-Al dispersion by Nuclear and Energy Research Institute
(IPEN/SP, Brazil) in nuclear reactor IEA-R1m is used. Its production by the mixture
of uranium silicide powder (U3Si2) with aluminum metallic (Al) in predetermined
proportions is realized. The quality control of U3Si2 as well as the Al powder is
important since ensures higher efficiency of the fuel element. In the aluminum
powder should be checked the impurities levels such as B, Cd, Co, Cu, Fe, Si, Mn,
Zn and others, and total aluminum. In this paper was evaluated the performance of
WDXRF and EDXRF spectrometers, using the methods of calibration curve with
certified reference materials and instrumental sensitivity curve, observing the legal
requirements of NBR ISO 17025. The results of both WDRXF and EDXRF showed
that precision, accuracy and limit of quantification were statistically suitable for
evaluated methods, however, WDXRF technique was more appropriate for the
method of instrumental sensitivity curve because can be determined a great
impurities number.
