专利汇可以提供Means for adjustable clamping skirt between pressure vessel and core专利检索，专利查询，专利分析的服务。并且Pads are joined to the inside surface of the pressure vessel in a nuclear reactor system, preferably through an electron beam welding process. Screw jacks fitted on the skirt within the pressure vessel engage the pads. The shapes of the pad bearing surfaces allow a longitudinal displacement of the reactor structure in response to thermal conditions. The novel features of the invention, moreover, eliminate skirt vibration and the requirement for high-precision construction.，下面是Means for adjustable clamping skirt between pressure vessel and core专利的具体信息内容。

权利要求

1. A nuclear reactor system comprising a generally cylindrical pressure vessel having an inner surface, a reactor core within said pressure vessel, jacketing enclosing said reactor core, a skirt interposed between said jacketing and the inner surface of said pressure vessel, wedging means for adjustably clamping said skirt between said pressure vessel and said jacketing, said wedging means having a plurality of screw jacks protruding through said skirt, said skirt further having a generally cylindrical structure having a plurality of holes formed therein, a plurality of sleeves each individual to a respective one of said screw jacks, said sleeves being received in said holes formed in said skirt, said sleeves having threaded apertures formed in the centers thereof to accommodate said respective screw jacks, said skirt also having a corrosion resistant plating formed on surfaces of said skirt, said skirt holes terminating in annular recesses that are formed in said plating and concentric with said holes, and a plurality of rings each received within a respective recess and welded to individual sleeves and said adjacent plating.

2. A reactor system according to claim 1 further comprising at least one transverse partition secured to said jacket and block means on said partition for supporting other wedging means.

3. A system according to claim 1 wherein said pressure vessel inner surface further comprises a plurality of plates formed thereon, each individual to a respective one of said screw jacks, each of said plates having a cylindrical surface formed thereon to receive said respective screw jack.

4. A system according to claim 3 wherein each of said plates further comprises a centrally disposed cell within each of said plates, said plates being in contact with said pressure vessel inner surface at said respective perimeters.

5. A system according to claim 4 further comprising a plurality of thickenings formed on said pressure vessel inner surface, each of said thickenings being individual to a respective one of said plates, said thickenings having machined surfaces in contact with corresponding surfaces on said plates.

6. A system according to claim 5 wherein said plates further comprise a plurality of sleeve means, each in contact with a respective one of said machined thickening surfaces, ana plurality of grooved discs each received within an end of one of said sleeve means, said grooves accommodating respective screw jacks.

7. A system according to claim 2 wherein said skirt further comprises a generally cylindrical shape having a plurality of holes formed therein, said holes being in alignment with said wedging means for manipulating said wedging means therethrough.
