Abstract
The present invention is intended to reduce thermosiphon effects within the annular space (6) situated between the pump casing (1) and the vertical wall (9) of an opening situated within the slab (3) covering the vessel for a nuclear reactor immersed in liquid sodium (4), with an inert gas (15) filling the space situated between the surface of the sodium and the bottom portion of said slab (3). The device to which the present invention pertains consists of a floating ring (7) placed around the pump casing (1) and a disc (8) which is integral with the vertical wall (9) of the opening situated within the slab (3). The shape of the aforementioned ring (7) and the shape of the aforementioned disc (8) are complementary with one another. Nuclear plants application.
