In a steam-water separator, a swirl vane () is provided inside a riser (), an annular downcomer space () is formed by providing a downcomer barrel () outside the riser (), a deck plate () is arranged above the riser () and the downcomer barrel () with a predetermined space therefrom, an orifice () and vents () are formed, and aperture ratios of plural slits (, and) formed on the riser () are set at from 30% to 70%. Accordingly, the steam and the water is appropriately separated, and the separated steam is reliably discharged upward from the orifice while the separated water is allowed to reliably flow down through the downcomer space, thereby enhancing steam-water separating efficiency.
