It is essential to be able to measure accurately the amount of fissile materials in a nuclear spent fuel reprocessing plant. Since the samples include large amounts of highly radioactive materials, preparation for analysis has to be done by using manipulators in hot cells. Because of this, the chemical preparation scheme has to be simplified, ensuring that at the same time the analysis is kept precise and accurate. Isotope dilution mass spectrometry has been applied as the appropriate tool for measuring uranium and plutonium isotope amount concentrations. Normally, the spiking step is the most critical point for IDMS. Therefore, the sample solution was directly introduced in to vials with solid spike avoiding the possibility of cross-contamination and reducing uncertainties arising from subsequent dilution steps.
