OSTI ID:4795870

A nuclear reactor serves for superheating the saturated steam produced in a boiling water reactor and comprises a pressure vessel, the lower portion of which is filled with water, while its upper portion is occupied by saturated steam fed into this portion via an entrance pipe. The core of the reactor is enclosed by a container completely immersed in the water in the lower portion of the pressure vessel. Through this core, a plurality of parallel reactor tubes Passes enclosing the fuel elements and being thermally insulated from the moderator water inside the core container which pressure is held at the same value as the pressure In the vessel. The reactor tubes of an outer zone are in communication, via the upper ends of them, with the saturated steam region of the pressure vessel from which the steam flows down passing through these channels and entering the lower header. The reactor tubes of an inner zone are fed from the said header from which the steam goes up passing through these channels and leaves the reaction by an upper header adapted for the reactor tubes of this inner zone.
