As you may see from BBC News, today marks the 20th anniversary of the worst nuclear accident in history. It was one of the first things I remember seeing on TV, and it's something that I've always been interested in finding more about. I've been following the plans for constructing a replacement for the Sarcophagus, starting next year, being in disbelief that they only actually shut the plant's final reactor in December 2000, and been amazed at the influx of wildlife to the area since the disaster. I've seen the chilling photos of ghost towns, gas masks sitting in nurseries, a ferris wheel due to open the week following the disaster, ready to collapse, never used, and the vast, vast "graveyards" of equipment used during the cleanup. I'm sure the world will mark this occasion, and ask if nuclear power is either a good or a bad thing (most would agree, that if done right, including safe disposal of waste, and "test runs" such as carried out on that night in 1986 aren't repeated, it is a safe practice - but I don't want this thread to turn in to an argument about the pros and cons of atomic energy), and I'm sure that here in Britain people will have something to say, as it's something that people have to live with - farmers in Wales still have to check livestock for radiation levels before selling them on. The legacy of this disaster will live on for centuries, probably millenia. Has the world learnt it's lesson from this catastrophe? (At least they've not built any more of the inherently unsafe RBMK reactors). • BBC News In Depth [here] • Timeline of Events [here] How do you remember it? Anything to say on this anniversary?
