    摘要： In a steam-water separator, a swirl vane (52) is provided inside a riser (51), an annular downcomer space (54) is formed by providing a downcomer barrel (53) outside the riser (51), a deck plate (55) is arranged above the riser (51) and the downcomer barrel (53) with a predetermined space therefrom, an orifice (56) and vents (57) are formed, and aperture ratios of plural slits (58a, 58b, 58c, and 58d) formed on the riser (51) 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.

    摘要： In a corium cooling promoting apparatus and a containment, a pressurized water reactor (12) is contained inside the containment (11), and a cavity (56) to which cooling water can be supplied in an emergency is provided below the pressurized water reactor (12). The cooling promoting apparatus (61) is disposed in the cavity (56), and an inclined plate (62) for spreading a corium (debris) from the pressurized water reactor (12) is provided, as the cooling promoting apparatus (61), at a position below the pressurized water reactor (12) in the cavity (56). The cooling of the corium falling from the nuclear reactor is thereby facilitated, and the corium is cooled at an early stage to improve safety.
