| Outline of Final Research Achievements |
The objective of the present study was to contribute to the improvement of the accuracy of database for neutron capture reaction cross sections used for the technological development of nuclear transmutation of long-lived nuclear wastes. First, the precise measurements of capture cross sections of long-lived nuclear wastes, i.e. Zr-93, Tc-99, Pd-107, I-129, Np-237, Am-241, Am-243, Cm-244, Cm-246, and related stable isotopes were performed. Then, theoretical analysis of the measured results was systematically performed, and the capture reaction mechanism of long-lived nuclear wastes was elucidated. Finally, reliable calculated capture cross sections for all long-lived nuclear wastes and in the whole neutron energy region were supplied.
