[2C18] Development of Ultramicro Analysis Technology for Fuel Debris Analysis
(5)Consideration of Analytical Methods for Actinide Elements with ICP-MS/MS
Keywords:Fuel debris, ICP-MS/MS, Actinides, Analytical chemistry
Inductively coupled plasma mass spectrometry with triple quadrupoles (ICP-MS/MS) is one of the promising techniques for rapid and highly sensitive wet analysis of fuel debris in Fukushima Daiichi nuclear power plant. The collision/reaction cell technology implanted in ICP-MS/MS is available option to eliminate isobaric interferences, being expected to simplify the pretreatment of fuel debris analysis. In this study, ICP-MS/MS measurements of 238U and 232Th with collision/reaction gases were performed. On the basis of their gas reactivity, analytical methods for U will be discussed.
