Section: claims

1. A metal liner having top, bottom and sides for lining the cylindrical cavity of a reinforced concrete pressure vessel for a nuclear reactor comprising: (a) a first plurality of stud shear connectors welded to the exterior side of said liner;  (b) a plurality of cooling tubes welded to the exterior side of said liner;  (c) a second plurality of stud shear connectors having a rigidity selected to withstand forces acting on an area of said liner greater than the forces acting on said liner in the area of said first plurality of stud shear connectors;  (d) at least one steel tube penetrating said liner;  (e) at least one area of said liner having a greater thickness than the remaining areas of said liner;  (f) a plurality of passages through said liner in said area of greater thickness; and  (g) a plurality of shear stud connectors and cooling tubes welded to the exterior of said at least one steel tube penetrating said liner.  said first plurality of stud shear connectors and said plurality of cooling tubes area arranged in a grid according to the forces acting on said liner. 2. The metal liner of claim 1, wherein: 3. The metal liner of claim 1, further comprising a plurality of reinforcing rods adjacent said second plurality of stud shear connectors and cooperating with said second plurality of stud shear connectors to transmit said forces away from said liner. 4. The metal liner of claim 1, further comprising means for securing said liner against the forces of friction. 5. The metal liner of claim 1, wherein said area of said liner having a greater thickness is void of any of said first or second plurality of stud shear connectors. 6. The metal liner of claim 1, wherein said cooling tubes and said shear stud connectors alternate with one another on said exterior side of said liner. 7. The metal liner of claim 1, wherein said second plurality of shear stud connectors are located on said liner at an area of increased stress. 8. The metal liner of claim 1, wherein said at least one steel tube is welded to said liner in the area of passage through said liner. 9. The metal liner of claim 1, wherein said second plurality of stud shear connectors are of different length than said first stud shear connector. 10. The metal liner of claim 1, wherein said second plurality of stud shear connectors are of a different diameter than said first stud shear connector. 11. The metal liner of claim 1, wherein said second plurality of stud shear connectors have bases surrounded by cavities filled with soft material softer than concrete or steel. 12. The metal liner of claim 1, wherein said liner has cylindrical sides. 13. The metal liner of claim 1, wherein said liner comprises a plurality of flat plates forming side walls. 14. The metal liner of claim 13, wherein the individual plates of the cylindrical part of the liner are seamed in the vertical direction in their center and the seam edges are meeting a weld each between two segments of the bottom of the liner and the roof liner wherein, the welds of the individual plates impact the center of a segment and wherein the individual plates are jointed directly by welding with said segments.
