摘　　要：The typical burnup feature in ADS system is that ADS needs more specific depletion chains for heavy nuclides and rational simplified depletion chains for LLFP.These depletion chains can be represented as set of first-order differential equations by means of transmutation trajectory analysis(TTA)method,and be solved using explicit analysis method,which is referred as Bateman equations.The applicability of this method has already been demonstrated by some famous codes,such as CINDER and BISON.There are also some other methods to solve burnup equations,for example,the exponent matrix method used in ORIGEN2 code and Chebyshev rational approximation method(CRAM)employed in burnup module of Serpent code.However,some general burnup codes have certain limitations,for instance,treating a series of important fission products including LLFP as pseudo nuclides or lacking several crucial MA isotopes.
