Abstract: The advantages of simultaneous transmutation of actinide nuclides and fission products in the accelerator driven coupled fast/thermal spectrum system（ADFTS） were investigated.Through the neutronics analysis of ADFTS,the energy amplifying principle was interpreted.The concepts of neutron amplification factor and neutron coupling factor of ADFTS were brought forward,and the calculating method of neutron amplification factor was introduced.And then,the breeding capability of accelerator driven system（ADS） was studied.The study results showed that ADS had higher capability in breeding fuel from fertile material over the traditional reactor.
