The elemental distribution of several pieces of fuel debris was obtained by scanning electron microscopy combined with wavelength dispersive X-ray spectroscopy. We also evaluated the microscopic isotope ratios of nuclides in fuel debris and their crystal structures by secondary ion mass spectrometry and transmission electron microscopy.
