专利汇可以提供Pressure suppression containment for a liquid-cooled nuclear reactor专利检索，专利查询，专利分析的服务。并且Containment apparatus and a pressure suppression system for a liquid-cooled nuclear reactor. The apparatus includes a safety container formed by a spherical pressure shell and a condensation chamber filled with water arranged within the safety container. The condensation chamber, which is annular in shape, is bounded on the outside by the safety container, on the inside by a cylindrical wall within the container, and at the top and bottom by annular ends respectively connecting the top and the bottom of the cylinder with the safety container. A plurality of condensation tubes are provided to pass through the upper end and extend into the water in the condensation chamber. The reactor pressure vessel of the nuclear reactor is located within the cylindrical wall and surrounded by a cylindrical biological shield. The diameter of the shield is less than the diameter of the cylindrical wall so as to form an annular passageway between the shield and the cylindrical wall from the calotte-shaped region of the safety container above, to the calotte-shaped region of the safety container below, the condensation chamber.，下面是Pressure suppression containment for a liquid-cooled nuclear reactor专利的具体信息内容。

权利要求

2. The apparatus defined in claim 1 wherein the upper and lower annular ends have the shape of sections of a toroid.

3. The apparatus defined in claim 2, further comprising a pressure strip means for reinforcing said Upper and lower annular ends.

4. The apparatus defined in claim 3, wherein said pressure strip means has a plurality of pressure struts connected to said shell and to said cylinder, and further including members each having a K-shaped cross section and connected to respective ones of said pressure struts, said shell, and a respective one of said upper and lower annular ends.

5. The apparatus defined in claim 4, further comprising a cylindrical extension projecting downward from said shell beneath said reactor pressure vessel.

6. The apparatus defined in claim 5, further comprising an access lock having at least two vertical lock doors, said access lock being attached to said cylindrical extension.

7. The apparatus defined in claim 5 wherein said tube means include a plurality of vertically arranged straight tubes, the upper ends of which are provided with outwardly flaring funnels and welded to said upper annular end.

8. The apparatus defined in claim 7 wherein the lower ends of said tubes are connected together by a brace.

9. The apparatus defined in claim 8, further comprising access walk means arranged within said condensation chamber and supported by said brace, for permitting inspection of the nuclear reactor.

10. The apparatus defined in claim 9, further comprising baffle plate means, attached to said brace, for preventing circulation of the water in the condensation chamber.

11. The apparatus defined in claim 10 wherein portions of said cylinder and said shell are provided with concrete cover means to prevent punctures in the regions of said cylinder and said shell which are subjected to pressure.

12. The apparatus defined in claim 11, further comprising pump means, arranged within said shell at said reactor pressure vessel, for circulating the reactor coolant.

13. The apparatus defined in claim 12 wherein said shell includes a steel wall surrounded by a sealing layer, said sealing layer being separated from said steel wall by spacing means, the space between said steel wall and said sealing layer being maintained at a reduced pressure.

14. The apparatus defined in claim 13 wherein said upper and lower annular ends are made of steel.

15. The apparatus defined in claim 14 wherein said shell is made of concrete.

16. The apparatus defined in claim 14 wherein said shell is made of steel.
