This decreased its output so much that there was not enough energy left over to power the water pumps when the switch-over occurred. Do RBMK reactors still have graphite tips?
WebAfter the SCRAM (AZ5) button was pressed to shut down the reactor, the control rods jammed in the middle of the core, causing a positive loop, since the nuclear fuel reacted to graphite. This has been dubbed the "final trigger" of events before the rupture. A graphite fire after the main event contributed to the spread of radioactive material. WebWere the graphite tips of the RBMK soviet reactor rods really to blame for the Chernobyl tragedy, or the anomalous circumstances created by the operators? It is mentioned by many sources as a design flaw. I would really appreciate if an engineer could enlighten me as to 1) what was the original purpose of graphite tips on the reactor rods?
