Validation of the CATHARE 1-D and 3-D reflood models against FEBA and ACHILLES experimental tests

•We used CATHARE2 and CATHARE3 codes to simulate scenarios featuring reflood conditions.•Both the 1-D and 3-D features of the CATHARE2 code have been adopted to simulate the experiments.•The quantitative analysis shows a systematic underprediction of the PCT and faster quenching in the majority of FEBA and ACHILLES tests.•The best agreement with experiment among the tested models is achieved using the 3-D model.•CATHARE2 has a tendency to improve the PCT prediction with increase of the bundle pressure and when increasing the inlet liquid velocity.
