One of the safety aspects in nuclear power is the early detection of corrosion of the metal alloy components of the cooling system. Direct determination of metals in cooling water is not possible due to very low concentrations. Therefore, filters are placed in the cooling system to collect corrosion residue over time.
Generally, these filters are analyzed by ICP-OES and must therefore be put into solution before analysis. The analysis time, including the preparation of samples, easily takes half a day. This method also requires the use of hazardous chemicals.
The EDXRF analysis does not require sample preparation. The filter is put into the instrument directly. The scan takes less than 10 minutes per filter. The analysis is non-destructive, which keeps the sample for future reference. The calibration of the instrument is straightforward, and the long-term stability is excellent.
