N2 - PARAGON2 is the new Westinghouse lattice physics code that is under validation and qualification, which uses a very fine multi-group energy mesh for neutron transport calculations. In this work, the criticality is calculated using PARAGON2 and MCNP5 and compared for three experiments, which are found in the International Handbook of Evaluated Criticality Safety Benchmark Experiments. The selected experiments were chosen based on several criteria to demonstrate the capabilities of PARAGON2, including high uranium enrichments greater than 5 w/o 235U, various fuel materials, and core geometries. The three cases show acceptable agreement between the criticality calculated by the two codes. In addition to the criticality, the fission reaction rates were analyzed to show agreement between the calculations of these rates. For these reasons, PARAGON2 is suitable for modeling cores with enrichments above 5 w/o 235U.
