Reactor vessel.

摘要

A pressure proof reactor vessel (10) and the method of making such vessel wherein the vessel has a cylindrical one-piece outer wall (11) and a cylindrical one-piece cylindrical inner liner (20), which liner has a smooth continuous interior surface spaced radially inwardly from the outer wall and concentric thereto. The inner cylindrical wall is formed from a one-piece material with its radial thickness being substantially less than the radial thickness of the outer cylindrical wall. Support means (21) in the form of a spiral is positioned in said space between the cylindrical outer wall (11) and the cylindrical inner liner (20) defining a pathway for the flow of coolant be ween the outer wall and the inner wall. The support spiral is secured to the outer surface of the one-piece cylindrical inner liner (20) prior to assembling of the inner liner to the outer cylindrical one-piece outer wall.
