Vessel or tank bottom for a pebble-bed reactor

摘要

Vessel bottom for a gas-cooled pebble-bed reactor, including a multiplicity of blocks having inclined upper surfaces and being disposed adjacent each other side by side with gaps forming therebetween during operation of the reactor, each immediately adjacent two blocks being in the form of a higher block and a lower block, and projections integral with the higher block of each of the immediately adjacent two blocks extended at least partly over the lower block thereof, the projections being wider than the gaps forming between the adjacent blocks.
