That’s a great picture.
And just so people are thinking about this the right way. From a safety perspective We don’t care about the graphite as long as it is in the fuel region or below the fuel region, because during a scram they go down which means graphite will be exiting the fuel region and control rods will be coming in.
It’s only a problem when those followers are all the way up and partially out. They will raise power below them as they drive down, right into the power peak.

Also gives a great look into why it's named RBMK. Reaktor Bolshoy Moshknosti Kanalnyy; High-power Channel-type reactor; since the cooling water is sent through individual channels as opposed to being in one large pressure vessel.
