The modular European Accident Code (EAC) analyses the initiation phase of low-probability whole-core accidents in LMFBRs, with the aim of predicting the rapidity of sodium voiding, the mode of pin failure, the subsequent fuel redistribution and the associated energy release. The paper gives a short overview of the development of the EAC-2 code with emphasis on the coupling mechanism between the fuel behaviour module TRANSURANUS and the thermohydraulics modules which can be either CFEM or BLOW3A. These modules are also briefly described. Some numerical results of EAC-2 are given: they are recalculations of an unprotected LOF accident for the fictitious EUROPE fast breeder reactor, which was analysed in the frame of a comparative exercise performed in the early 80s.
