'Fukushima plutonium leak comparable to Chernobyl disaster'

Japanese government is considering the construction of a containment shell at the damaged Fukushima nuclear power plant. It would be aimed at averting further radiation leaks in a crisis that is still described as 'grave'. The plan would involve the three most badly damaged reactors being covered with hi-tech material. The level of radiation measured in sea water near the site, is now said to be around three and a half thousand times higher than normal. Workers have been unsuccessfully trying to restore the cooling system at the facility, in what is now the worst atomic crisis since Chernobyl. RT spoke to nuclear energy expert Lars Polmeier, who says there are parallels with that disaster 25 years ago.
