Why graphite is used in nuclear reactors

TechnologyARMY on Instagram: "Chernobyl’s Reactor No. 4 was not an ordinary machine. It was an RBMK-1000—one of the Soviet Union’s most powerful energy sources. But hidden inside its design was a fatal flaw. ☢️⚠️ On April 26, 1986, during what was supposed to be a simple safety test, that flaw was exposed. As cooling water turned into steam, the reactor’s power didn’t drop—it spiraled out of control. Within minutes, it became a massive explosion. Its graphite-moderated design intensified the dis

Two technicians in white protective suits stand nearby, likely during maintenance, refueling, or inspection in the reactor hall —standard gear for nuclear workers to spot contamination easil
