| 摘要 |
The invention relates to a container (1) for accommodating and diffusing a molten reactor core (27) in a nuclear power station with a structured cartridge-like bottom (3). The bottom (3) consists of a good thermoconductive material, multiple geodetically uppermost-lying points (4), multiple geodetically lowermost-lying points (5) and an outer wall (15). The outer wall (15) runs ascendingly between a geodetically lowermost-lying point (5) and an adjacent geodetically uppermost-lying point (4). A steam pipe runs through the inside (17) of the container at each geodetically uppermost-lying point (4). The container (1) enables external cooling of the molten reactor core (27), thereby avoiding the formation of radioactive aerosols, the risk of steam explosion and the formation of hydrogen. Cooling is particularly effective on account of the ascending run of the external wall, since the formation of a fixed localized vapor zone accompanying lower thermoconductivity is prevented. The invention also relates to a nuclear power station with a container (1) for accommodating and diffusing a molten reactor core. |
