Abstract

A nuclear reactor installation is housed inside a spherical safety casing (2). The reactor is disposed in a pressure vessel (1) and a discharge duct (3) connects the interior of the safety casing (2) to a chamber (4). In the event of an accident causing a core meltdown, the molten reactor core can pass through the discharge duct (3) into the chamber (4). The duct (3) is lined with an anhydrous fire-proof lining (23) of refractory elements, while the chamber (4) is lined with a water-cooled steel jacket (41). The molten core material, after passing through the duct (3), will flow over a distribution core 42 lying on a bed (43) of anhydrous material e.g., basalt or asbestos, which absorbs the molten material. The bed (43) is mounted on a support (44) provided with radial expansion slots through which the molten material can flow. A second collar-shaped, water-cooled steel jacket (45) is provided.
