ABSTRACT:
A heat exchanger for a nuclear reactor of the cavern type comprises a double walled vessel disposed within a steel liner. The vessel contains a large number of reaction tubes provided with a catalyst through which the material to be reformed flows. The outlet pipes of the reaction tubes act as a heat exchanger in the outer space of the vessel, which is filled with water. The vessel rests upon a bracket on the lower part of the liner, and the space between the liner and vessel in the region of the bracket is sealed by a double flange structure. At the top of the vessel, seal is effected by a cover, membrane ring, and a double flange arrangement. The annular space between the liner and vessel is sealed by a packing against the recycle gas nozzle leading from the interior of the vessel.
