Two--phase critical flow models of two codes are analyzed and assessed. Under upstream low sub-cooling or low guality conditions,the critical mass flow is underperdicted by RELAP5/MOD2 code andit can not reflect the influence of geometry L / D on critical flow. The critical flow model in CATHAREcode is more sophisticated, and the calculated critical mass flow agrees well with experimental data.
