Measurements of nuclear data of minor actinides for transmutation of high-level waste

For nuclear transmutation of minor actinides, delayed neutron emission meas urement for Am-241 was carried out in thermal neutron irradiation location. The neutron capture cross sections of Am-241 were also measured radiochemi cally. The transmutation process of Am-241 in reactor is discussed by calcu lating the yields of minor actinides with the nuclear data measured in this study and the evaluated values. The accelerator driven transmutation of mi nor actinides by high-flux neutrons from spallation reactions is also prese nted.
