| Outline of Final Research Achievements |
In this study, we proposed a new concept of the "self-indication method" combined with neutron resonance transmission analysis and neutron resonance capture analysis for non-destructive assay using a pulsed neutron source. It was confirmed that the effective thickness of target nuclide can be determined within 3 % accuracy by experimental validation. Moreover, the results indicated that the self-indication method has a high-sensitivity for assaying target nuclide in a mixture material such as spent nuclear fuels.
