This paper focuses on the opportunity given by the CABRI experiments tocontribute to the validation of High-Fidelity multi-physics computational tools; itdoes not address the safety demonstration for the CABRI reactor that is based on arobust and conservative approach that does not need the use of high-fidelity multiphysicsmodelling and simulation tools. The paper first presents a general approachand recommendations to be used to meet the requirements for experimental dataand associated uncertainties in order to validate multi-physics modelling andsimulation tools. After a short presentation of the CABRI facility, it then providesa review and critical analyses of the multi-physics available experimental data forCABRI. Finally, it addresses the adequacy and completeness of the CABRIexperimental datasets for the validation of multiphysics computational tools, aswell as promising perspectives in terms of instrumentations that could fill in thegaps in terms of information in the future experiments.
