The accelerator-driven sub-critical system (ADS) has been recognized as a promising approach for managing spent nuclear fuels, particularly long-lived fission products (LLFP) and minor actinides (MA). Most burnup codes currently lack a fixed-source depletion mode, which is a key characteristic of ADS. Some depletion codes that can perform ADS calculations require coupling at least two simulation codes. This study based on the concept of two-step method, applying the predictor-corrector, fourth-order Runge-Kutta, to calculate the depletion problem for ADS. All calculations in this study are performed using MCNP 6.1 with the ENDF/B-VII cross section library. First, the method is validated with the IAEA-ADS benchmark, and show good agreement with other references. After that, more complex model, EFIT, is simulated. The results show a slightly difference with reference due to the different calculation method. This depletion method is reliable for solving ADS burnup problem.
