Abstract
A thermal protection device which prevents the formation of neutral gas thermosiphons within the annular space formed between a reactor vessel wall and the shell of a top closure structure from which the vessel wall is suspended essentially consists of one or a number of packing rings fitted and compressed within the annular space, each ring being made up of a series of elements placed in adjacent relation at the periphery of the closure structure.
