The controlled chain reaction

• 1948 Hanford / Washington, USA:
  a radioactiv cloud of iodine 131 with 5500 Curie exits the atomic research center
  
• 1952 and 1953 Windscale / Sellafield, Ireland:
  the reprocessing plant releases a large amount of Plutonium into the Irish Sea, "just to see what's happening"
  
• 1957 Windscale / Sellafield, Ireland:
  a fire in the reprocessing plant releases a large amount of radiation into the atmosphere, noticed not earlier than three days later
  
• 1958 Vinca / Belgrade, Yugoslavia:
  another large amount of radiation is set free in the nuclear research plant. Six of the scientists get injured.
  
• 1957/58 Majak, Ural, USSR:
  worst atomic disaster so far: explosion in an atomic waste deposit. 30 villages wiped out, polluted lakes, hundreds of people get killed.
  
• 1966 Desert Gobi, China:
  accident in a factory for atomic weapons. 20 workers get injured.
  
• 1978 Tihange, Belgium:
  reactor accident in the local nuclear plant. 80 people get severly contaminated.
  
• 1978 Platteville / Colorado, USA:
  cooling system error in the area's nuclear plant. 15 workers contaminated.
  
• 1979 Harrisburg / Pennsylvania, USA:
  a radioactive cloud exits the Three Mile Island reactor. 8 workers get injured, 200.000 people have to leave their homes (evacuation).
  
• 1985 Harrisburg / Pennsylvania, USA:
  radioactivity exits the Three Mile Island reactor – again
  
• 1983 Wolgodonsk, UdSSR:
  heavy disaster in a reaktor factory
  
• 1984 Kalkar, West Germany:
  50 - 150kg of sodium starts to burn - the fire brigade uses water for it's extinction
  
• 1985 Trawsfynnydd / Wales, GB:
  fire in the reactor's turbine builing, could be ectincted in time.
  
• 1986 Oklahoma, USA:
  accident in a uranium converting plant. 1 dead, 26 injured.
• 1986 Chernobyl, USSR:
  second worst catastrophe so far, reactor burns, thousands of people die
  
• 2006 Forsmark, Sweden:
  blackout in the reactor, for more than 20 minutes no one has a clue of the reactor's state
  
• 2008 Tricastin, France:
  radioactive liquids exit three times from the reactor into rivers
