The main modelling options of ERANOS 2.0, the latest version of the ERANOS fast reactor analysis code and data system, are described. These include the ECCO cell and lattice code (Collision Probability Method in many groups using the subgroup method), the BISTRO 2-D S n transport code, the TGV/VARIANT 3-D Nodal Variational Transport code, and a special procedure for creating equivalent homogeneous cross sections for control rods. The recommended "reference" core calculation route is presented. A summary of the ERANOS extensive validation is provided. It is concluded that ERANOS 2.0 can predict the main characteristics of conventional as well as advanced liquid-metal-cooled fast reactors with an excellent accuracy, and that it can also be used for modelling advanced fast reactor cores, source-driven sub-critical media and gas-cooled fast reactors.
