Chernobyl reactor moderator
WebChernobyl is a type of reactor called an RBMK (Russian acronym) which uses a graphite moderator and water coolant. Similarities The RBMK and a typical U.S. LWR are both thermal reactors that burn uranium dioxide fuel. WebMar 19, 2011 · Now, in a graphite-moderated core, water (which is normally a moderator in an LWR) is actually a neutron poison. When the tip (not an absorber) of the control rod was inserted, it displaced the water, which removed the -reactivity, or otherwise inserted more + reactivity - and boom - the neutron multiplication took off - very quickly.
