Chernobyl. Remains of the Chernobyl nuclear power station in the Ukraine (formerly part of the USSR) soon after the accident which occurred on 25th April 1986. It happened during a low-power experiment with the No.4 RBMK-type reactor. The core overheated and caused a steam explosion which breached its containment building. The RBMK design did not include a secondary containment structure which would have prevented release of the core's contents. Over a billion billion becquerels of radioactive nuclides were released into the atmosphere, contaminating much of northern Europe. The three other RBMK units at Chernobyl were returned to power within the year.
