The graphite rods in the nuclear reactor
Web26 Apr 2016 · The RBMK reactor uses graphite as a moderator, whereas water in the reactor acts as what’s known as a ‘poison’ – capturing neutrons much like control rods and slowing the fission reaction. This is a major difference: whereas the loss of water in a normal BWR would stop the reaction, in the RBMK, reactor power will increase if water is lost.
