ABSTRACT:
A nuclear reactor including a vertically extending reactor vessel containing a number of reactor components and located within a cavity defined by a vertically extending, circumferential cavity wall assembly is disclosed herein. The reactor also includes a particularly designed guard vessel arrangement including a guard vessel located around and spaced from the reactor vessel between the latter and the cavity wall assembly. The guard vessel is supported by means in the shape of an inverted frustum which not only serves as a support but which also acts as a means to provide a uniform temperature gradient between the guard vessel and cavity wall assembly and provides for ready access into the space between the two vessels by suitable equipment for providing in-service inspection of the vessel walls defining this space.
