Keywords:
Fukushima Daiichi Nuclear Power Station accident,Fuel debris,Solid analysis,Solution analysis
Elemental analysis of the fuel debris dissolved by mixed acids and SEM-EDX analysis of the undissolved residue were carried out.
Consequently, the elements from fuel components, reactor materials and accident environment were qualitatively and quantitatively confirmed. And also, isotope ratios of nuclides from fuel and neutron absorber were measured.
