Keywords:Two-phase flow, Geysering

The natural circulation type BWR has the possibility of generating a geysering phenomenon under the condition of low heating amount and low pressure at startup.We experimentally clarified the mechanism of the geysering phenomenon and investigated the fluctuation of temperature and pressure by numerical analysis.
