A pressure proof reactor vessel and the method of making such vessel wherein the vessel has a cylindrical one-piece outer shell (11) and a cylindrical one-piece cylindrical inner shell (20), which inner shell has a smooth continuous interior surface spaced radially inwardly from the outer wall and concentric thereto. The outer cylindrical shell (11) is formed from a one-piece material with its radial thickness being substantially greater than the radial thickness of the inner cylindrical shell (20). Support means (21) in the form of a spiral or vertically disposed is positioned in the space between the cylindrical outer surface wall of the inner shell (20) and the cylindrical outer shell (11) defining a pathway for the flow of coolant between the outer wall and the inner wall. The support means is secured to the inner surface of the one-piece cylindrical outer shell while the inner shell is plug welded (25) to the support means (21). <IMAGE> <IMAGE> |
