Non-destructive analysis is required in many fields, such as nuclear transmutation, decommissioning, nuclear non-proliferation and nuclear security. By creating innovative technology, we would like to play leading role in dealing with development of non-destructive analysis in the nuclear field. We directly address the issue in the nuclear field by combining and improving the non-destructive analytical method, for instance differential die-away (DDA) and neutron resonance transmission analysis (NRTA). We have also developed the cutting edge technology related to prompt gamma-ray analysis and neutron imaging by using an intense pulsed neutron in J-PARC MLF.
