Understanding the properties of fuel debris is necessary for decommissioning the Fukushima Daiichi Nuclear Power Station (1F). An essential technique is the chemical analysis of actinide nuclides. In this study, actinide separation from FUGEN irradiated fuel solution was performed by extraction chromatography with tri-n-butyl phosphate impregnated resin (TBP resin). The irradiated fuel was used for a simulant of fuel debris in 1F. The chromatograph behavior revealed that uranium was separated from other actinides selectively.
