Application of ICP-MS to analysis of samples from 1F site at Radioactive Material Analysis and Research Facility

Do, V. K.  ; Horita, Takuma ; Miura, Katsue; Iwasaki, Maho

Radioactive Material Analysis and Research Facility has been recently established to support the analysis of samples including fuel debris and radioactive wastes from the decommissioning of Fukushima Daiichi Nuclear Power Station (1F). ICP-MS is considered as a potential analytical tool for long-lived nuclides in fuel debris because of its superior sensitivity. Moreover, the use of ICP-MS is aimed to increase the analysis capacity, which make possible to repeat measurements in order to obtain precise results and to reduce exposed dose of analysts because ICP-MS is much more rapid than radiometric methods. Employing latest advanced technologies, a triple quadrupole ICP-MS, Agilent 8900 (ICP-QQQ-MS), enables to suppress the isobaric interference. In this presentation, we report some demonstrative separations of difficult-to-measure nuclides using the ICP-QQQ-MS system. The obtained results indicate that the separations are possible with suitable reaction gases.
