The accelerator-driven subcritical system has promising future in transmutation of nuclear spent fuels[1].In this study,the Monte Carlo codes of FLUKA and OpenMC are selected to deal with the ADS problem since these two codes are free-source codes and also the coupling codes that have the potential to deal with ADS problems.In order to satisfy the demands of interactive modeling with FLUKA and OpenMC codes,solve the complicated modeling problems and make the modeling process more easier,a compatible interactive modeling program for these two codes,which is called CAD-PSFO based on an open source software FreeCAD,has been developed for ADS facility,and also a CiADS benchmark has been tested with this program in this paper.
