A Ge crystal dimension of a pair-spectrometer system was optimized to improve its performance for the prompt 
-ray spectroscopy. To study the performance of the pair-spectrometer system, the prototype system was developed and applied to the measurement of prompt -rays which are emitted from 15N produced in thermal neutron capture reaction, in the energy range up to 10.8 MeV.

To develop a commercialized fast reactor cycle system involving the recycling of minor actinide (MA) nuclides, Japan Nuclear Cycle Development Institute has launched the isotopic composition analysis of post irradiation examination (PIE) results for fuels and MA samples irradiated at the experimental fast reactor "JOYO". This paper presents the target accuracy of MA nuclear data, as well as the progress in validation of those by PIE analyses. The analysis result on the first examined MA sample suggested the necessity of re-evaluation of the isomeric ratio for 241Am capture reaction both in ENDF/B-VI and in JENDL-3.3.
