Скачать или смотреть Chernobyl Disaster - The Risk of a 2nd Explosion

The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine (then officially the Ukrainian SSR), which was under the direct jurisdiction of the central authorities of the Soviet Union.

After the disaster, the pools and the basement below the reactor were flooded because of ruptured cooling water pipes and accumulated firefighting water, and constituted a serious risk. The smoldering graphite, fuel and other material above, at more than 1200 °C, started to burn through the reactor floor and mixed with molten concrete from the reactor lining, creating corium, a radioactive semi-liquid material comparable to lava. If this mixture had melted through the floor into the pool of water, it was feared it could have created a serious explosion.

Vassili Nesterenko - Nuclear Physicist: "Our experts studied the possibility and concluded that the explosion would have had a force of 3-5 megatonnes. Minsk, which is 320km from Chernobyl, would have been razed, and Europe rendered uninhabitable."
