One of the tools for safety analysis of light water reactors is the subchannel methodology which is used for evaluation of the limits with regards to departure from nucleate boiling (DNB). This approach utilities subchannel code which has to be validated against experimental data. In this work, the ALTHAMC12 subchannel code is validated against critical heat flux data measured at test section with hexagonal geometry. Validation is performed using the PG-S and OKB correlations of critical heat flux (CHF). The experimental data library is based on public literature sources. The analysis shows that PG-S correlation provides prediction of CHF close to experimental values. The OKB correlation underestimates the CHF and thus provides conservative results for safety analysis.
