29 November 2012, two days ago workers in Ukraine raised steel arches over the entombed Chernobyl reactor: “This is a very significant milestone, which is a tribute to the ongoing commitment of the international donor community, and an important step towards overcoming the legacy of the accident.”-Suma Chakrabarti, European Bank for Reconstruction and Development

Those new steel arches weigh 5000 metric tons (5,511.5 tons), and are 22 meters (72 feet) tall!  The steel container won’t be finished until 2015.  It’ll weigh 20000 metric tons (22,046 tons) and is designed to allow ongoing decontamination work for the next 100 years!

26 years ago the Soviet designed reactor melted down, and it’s still spewing radiation.

The Soviets slammed Chernobyl with tons of concrete, sand and boric acid.  The impromptu concrete tomb was breaking down and a new one was built.  But even that one is breaking down, so a new massive steel tomb is being built, hopefully to contain the radiation for the next century.

Now realize that Chernobyl is only one reactor, with no spent fuel storage, and Japan’s General Electric designed Fukushima Daiichi melt down disaster involves at least four damaged reactors with four spent fuel pools that contained hundreds of fuel rods, each.

Initially Tokyo Electric Power Company (TEPCo) said they could have Fukushima Daiichi cleaned up by July 2011!!!  In December 2011 the Japanese government published their own report, saying cleanup will take at least 40 years, TEPCo downplayed the government report.  Then in March 2012, TEPCo admitted that reactors actually melted down.  Now, at the beginning of November 2012, TEPCo is admitting that clean up will take much longer, and they’ve even doubled their estimated cleanup and compensation costs from $62.5 billion USD to $125 billion!
