The objective of this paper is to present the main results of the keff inter-comparison exercise performed in 2019-2022 by LANL, LLNL, ORNL and IRSN on a set of common benchmarks. The paper includes a description of the methodology to make the inter-comparison, presents the set of selected cases along with the main tendencies that could be at-tributed to nuclear data. In addition, it identifies some issues on the processing and interpretation of nuclear data done by the various codes of the intercomparison.
