RBMK Nuclear Power Plants RBMK is the acronym for graphite moderated, boiling water cooled channel type reactors designed in the former Soviet Union. The rods are arranged in hexagonal fuel assemblies which are placed inside pressure fuel channels. The fuel channels are installed in a graphite matrix. The channels are cooled by water which boils as it goes through the channels.
Drums separate the steam from the water.
The steam drives the turbine and the water is recirculated to the channels via main circulating pumps and group distribution headers.
