摘要： A nuclear reactor has a propagation chamber (4) for the molten core (17) equipped with a coolant pipe (6) that leads to a coolant reservoir and has a temperature-dependent opening device (16). The coolant pipe (6) in the propagation chamber (4) is a spraying pipe whose spraying surface corresponds to the cross-section of the propagation chamber (4). The opening device (16) is controlled in such a way that it opens when the molten core (17) enters the propagation chamber (4). The sprayed coolant forms a crust on the molten core (17), reducing its heat radiation. At the same time, the propagation chamber (4) is filled with a vapour atmosphere that drastically reduces the thermal stresses to which the building structures are subjected.

摘要： The proposal is for an inherently safe, temperature-dependently opening closing device on a connecting line (5) for coolant to initiate the cooling of a core melt (3) in a nuclear reactor plant. The connecting line (5) projects on the outlet side into a collecting chamber (1) for the core melt (3) and is connected on the inlet side to a cooling water tank (9). At the outlet end of the connecting line (5) there is a closing member (7) which normally closes the outlet end (5. 1) and opens under the effect of heat with the release of at least a part of the outlet cross-section of the connecting line (5) so that the coolant (6) is taken from the cooling water tank (9) to the collecting chamber (1) via the connecting line (5). There are means (A1) to keep the cold flow of the cooling water column away from a temperature-dependent opening device of the closing device (7), said opening device being largely corrosion resistant. The preferred application of the invention is to "core catchers" operating on the expansion principle.

摘要： The device proposed includes an expansion chamber (12) into which the meltdown products (16) flow in the (unlikely) event of a failure of the reactor pressure vessel (4). The meltdown products (16) are cooled in this expansion chamber (12) by means of a coolant (19) fed into the chamber. The invention calls for particular attention to be paid to preventing the floor (24) of the expansion chamber (12) from becoming too hot. To this end, a cooling system (26) with a multiplicity of coolant channels (28, 30) is fitted in the expansion-chamber floor (24). At the latest immediately after meltdown products (16) have emerged from the reactor, coolant (19) flows automatically into the coolant channels (28, 30) so that the meltdown products (16) spreading into the expansion chamber (12) are also cooled from underneath.

摘要： The device proposed comprises an antechamber (30) located below the reactor pressure vessel (4) and connected by a channel (36) to an expansion chamber (34). Fitted over the inlet to the channel (36) is a bulkhead or partition (38) which is destroyed by the reactor-meltdown products within a predetermined time interval after the arrival of the meltdown products. A coolant reservoir (50) is connected to the expansion chamber (34), the connection being closed off by a closure element (48) which is also destroyed by the meltdown products. If the closure element is destroyed, by being melted or burst for instance, the coolant flows on to the meltdown products in the expansion chamber (34) and the meltdown products are efficiently cooled.
