[2B21] Research on the stability of fuel debris consisting of oxides and alloys
(2)Analysis of chemical state of U-Fe-Cr-Ni oxide by spectroscopic method
Keywords:Fuel debris, Fukushima Daiichi NPP Accident, debris consisting of oxides and alloys
In this presentation, we will report the results related with the chemical states on the surface of the simulated fuel debris which is synthesized from uranium and stainless steel and single component of uranium oxides are identified by fluorescence microscopy, raman microscopy and Mössbauer spectroscopy.
