Abstract

Burnup analysis plays an important role in the design of ADS since subcritical reactor has complex geometry structure as well as anisotropic ux distribution caused by external source. In order to simulate burnup, a Monte-Carlo Activation and Depletion Code System (MCADS) has been developed combining advantages of MCNP in complex geometry neutron transport calculation with LITAC in fast and precise inventory calculation. Then, IAEA ADS-Benchmark (stage1) is worked out, verifying that the code can be used to deal with subcritical reactor with an external source. Also, burnup, source evolution, void reactivity, initial spatial power density distribution are gured out with the code, showing good agreement with results from other countries.
