The objective of the current study is to evaluate the performance of the last version of the French best
estimate thermal-hydraulic code CATHARE 2 regarding void fraction prediction, comparing the
analytical results with the experiments in the framework of International OECD/NRC Benchmarks based
on NUPEC (Nuclear Power Engineering Corporation) BWR Full-size Fine-mesh Bundle Tests (BFBT)
and PWR Subchannel and Bundle Tests (PSBT). The results show reasonable prediction of the void
fraction distribution in broad range of variation of the operational parameters: pressures, mass fluxes,
power and inlet subcooling, which characterize the operation of Light Water Reactors.
