Graphite moderated nuclear reactors
WebINNO4GRAPH – INNOvative tools FOR dismantling of GRAPHite moderated nuclear reactors. All power plants have a finite life beyond which it is not economically feasible to operate them. In this case, they need to be decommissioned, cleaned up and demolished. The EU-funded INNO4GRAPH project will develop a set of tools and methods for … WebThe RBMK was the most relevant graphite-moderated reactor developed by the USSR for electricity generation. When the mid-1970s brought the world oil embargo, nuclear power seemed the easy answer to reduce our dependency on oil.

There have been two major accidents in graphite-moderated reactors, the Windscale fire and the Chernobyl disaster. In the Windscale fire, an untested annealing process for the graphite was used, causing overheating in unmonitored areas of the core and leading directly to the ignition of the fire. The material that ignited was not the graphite moderator itself, but rather the canisters of metallic ur… WebFeb 25, 2024 · The Chernobyl plant, known as a “first-generation” reactor, used graphite as a “moderator,” to slow neutrons down and facilitate fission chain reactions.
