In the framework of the Horizon 2020 project ESFR-SMART, the European Sodium Fast Reactor (ESFR) core was updated through a safety-related modification and optimization of the core design from the earlier FP7 CP-ESFR project.

This study is dedicated to neutronic analysis of the new SFR core. The conducted work is reported in two parts. Part I dealt with the evaluation of the safety-related neutronic parameters of the fresh core carried out by 8 organizations using both continuous energy Monte Carlo and deterministic computer codes. A special emphasis was put on the calibration and verification of the computational tools involved in the analyses.

Part II is devoted to once-through and realistic batch-wise burnup calculations aiming at the establishing of the equilibrium core state, which will later serve as a basis for detailed safety analyses.
