Claims
- 1. An apparatus for catching, fragmenting and then cooling a melt, including a core melt in a containment of a nuclear power plant, the apparatus comprising:
a porous body having a flow resistance to which a prepressurized coolant can be fed with a feed-flow rate which is limited by said flow resistance of said porous body.
- 2. The apparatus according to claim 1, including a supporting substructure, and said porous body is a layer applied to said supporting substructure.
- 3. The apparatus according to claim 1, wherein said porous body contains a porous composite material.
- 4. The apparatus according to claim 3, wherein said porous composite material is porous concrete, which contains at least one of an aggregate, a binder and a ceramic.
- 5. The apparatus according to claim 1, wherein said porous body is constructed from particles being at least one of regular particles and irregular particle.
- 6. The apparatus according to claim 5, wherein said particles contain at least one of a mineral material, steel, cast iron and a ceramic.
- 7. The apparatus according to claim 1, including a sacrificial layer covering said porous body.
- 8. The apparatus according to claim 7, wherein said porous body has cavities formed therein which are to be completely filled with the pre-pressurized coolant.
- 9. The apparatus according to claim 7, wherein said porous body and said sacrificial layer are cast together in their boundary region.
- 10. The apparatus according to claim 7, including a sealing layer disposed between and separating said porous body and said sacrificial layer.
- 11. The apparatus according to claim 10, wherein said sealing layer is formed from at least one material selected from the group consisting of metals and plastics.
- 12. The apparatus according to claim 1, wherein said porous body is to be disposed directly beneath a reactor pressure vessel.
- 13. The apparatus according to claim 12, including a core-catching device and a channel connected to said core-catching device, said porous body is disposed laterally offset below the reactor pressure vessel and is connected to said core-catching device by said channel.
- 14. The apparatus according to claim 1, wherein said porous body has an underside and side faces and the pre-pressurized coolant can be fed to at least one of said underside and said side faces of said porous body over a large area.
- 15. The apparatus according to claim 1, wherein said porous body has an underside and side faces, and including channels connected to said porous body, the pre-pressurized coolant is fed to at least one of said underside and said side faces of said porous body through at least one of said channels and over a large area.
- 16. The apparatus according to claim 1, including:
a coolant reservoir; and a cooling channel connected between said coolant reservoir and said porous body and the pre-pressurized coolant is supplied through said cooling channel which leads from said coolant reservoir.
