The characteristics of flashing-induced instabilities, which are of importance for the start up of natural-circulation boiling water reactors, are studied. Experiments at typical start-up conditions (low power and low pressure) are carried out on a steam/water natural circulation loop. Flashing and the mechanism of flashing-induced instability are analysed.
