Abstract
We proposed a system of neutron resonance densitometry for quantification of nuclear materials in particle like debris of melted fuel in the reactors of the Fukushima Daiichi nuclear power plant. Techniques of neutron resonance transmission analysis and neutron resonance capture analysis are applied to this system. Research and development have started under the support of JSGO/MEXT.
