Abstract
A top reflector for a nuclear-reactor vessel, i.e. the containment for a nuclear-reactor core, especially of a high-temperature or pebble bed reactor, is composed of laterally contiguous bodies (e.g. of graphite) which can be suspended from a support and in which means is provided for the form-fitting interengagement of the adjacent bodies to prevent collapse of the top reflector upon failure of the suspension.
Claims9
In a nuclear reactor having a housing enclosing a nuclear reactor core and a support for a planar top reflector, the improvement which comprises a top reflector assembled from blocks and form-fittingly interconnected with a toothed structure at adjoining lateral faces of adjacent blocks for retaining said blocks against collapse upon failure of said support, said blocks being prismatic and having vertical corners formed with cylindrical segmental recesses defining with corresponding recesses of other blocks cylindrical passages, and respective rotatable plugs received in said passages, the walls of said recesses being provided with grooves and said plugs having flights engaging said grooves, said support comprising rails spanning said core and means for mounting said blocks on said rails.
