How many control rods are in a rbmk

WebRBMK reactors work by taking uranium atoms that split apart and collide, this causes the reactivity to go up. This reactivity needs to be balanced or else it would never decrease. That is where the boron control rods come in and reduce reactivity. Water is another element that contributes to the reduction of reactivity. 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?
