ABSTRACT:
In a reactor confinement structure comprising a thin-walled inner reactor enclosure, a thick-walled outer enclosure, and an intermediate space containing water and an air cushion above the water, a communication between the enclosures is provided by bubbling ducts extending from the inner enclosure to a point below the water level. The flow of steam within each duct as a result of an accident condition within the inner enclosure is separated and then mixed with the water by means of a variable-depth partition system employed in conjunction with a system of injection nozzles and convergent-divergent tubes.
