Retrieval of nuclear fuel debris from the pressure vessels of Fukushima Daiichi NPP is an important issue. Understanding the distribution of physical or chemical property over the whole debris will help the safe and quick retrieval. We are going to apply a dual X-ray energy CT technique to the elemental analysis of fuel debris samples.
