This paper presents the results of the latest version of TRIPOLI-4 [1] on its criticality validation suite, part I dedicated to thermal spectra. The criticality validation suite is made of 148 carefully chosen ICSBEP [2] benchmarks with various enrichments, fissile materials and spectra. The ICSBEP benchmarks computational models are prepared by the TRIPOLI-4 VetV team and are run in the same conditions for each benchmark initial source, number of neutrons per cycle, number of inactive and active cycles, keff estimator, nuclear data. Comparisons are made with the measured keff as well as with previous versions of TRIPOLI-4.
