| Outline of Final Research Achievements |
We have established non-destructive elemental analysis method, which is based on a time-of-flight prompt gamma-ray analysis (TOF-PGA) combining prompt gamma-ray analysis (PGA) and neutron resonance capture analysis (NRCA), using neutron filters, highly efficient neutron shielding, accurate correction method and newly developed analytical codes. The established method has been succeeded to analysis non-destructively of difficult-to-measure radionuclides Pd-107 and Tc-99 in simulated samples of Tc-platinum group metals, which are essentially the same as obtained through group portioning processes of spent nuclear fuel materials.
