Several picecs of fuel debris were dissolved using simple dissolution method that employed nitric acid solutionwith trace hydrofluoric acid. Nuclides in dissolved fueldebris solution were analyzed by inductively coupled-plasma mass spectrometry and radiation measurements.

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.

In order to steadily carry out decommissioning of the Fukushima Daiichi Nuclear Power Plant (FDNPP), it is extremely important to understand the properties of fuel debris. In the past, analytical methods such as SEM-EDS, TEM and ICP-MS have been used to determine the properties of fuel debris. However, these analytical methods cannot obtain information on the local isotopic composition of the sample. FIB-TOF-SIMS, which the authors are developing, is expected to be a useful analytical method for determining the properties of fuel debris because it allows local isotopic composition analysis. In this study, we conducted analysis in a micro-area of FDNPP contaminated sample and succeeded in obtaining isotopic composition imaging of Li, B, and U from the measured particulates.
