'Suicide squads' paid huge sums amid fresh fears for nuclear site
The radioactive core in one reactor at Fukushima's beleaguered nuclear power plant appeared to have melted through the bottom of its containment vessel, an expert warned yesterday, sparking fears that workers would not be able to save the reactor and that radioactive gases could soon be released into the atmosphere.
Richard Lahey, who was a head of reactor safety research at General Electric when the company installed the units at Fukushima, said the workers, who have been pumping water into the three reactors in an attempt to keep the fuel rods from melting, had effectively lost their battle. "The core has melted through the bottom of the pressure vessel in unit two, and at least some of it is down on the floor of the drywell," he said.
The damning analysis came as it emerged that workers at Japan's stricken nuclear plant are reportedly being offered huge sums to brave high radiation in an attempt to bring its overheated reactors under control. The plant's operator, the Tokyo Electric Power Company, is hoping to stop a spreading contamination crisis which could see another 130,000 people forced to leave their homes.
Radiation has already found its way into milk, vegetables and tap-water and is leaking into the sea around the complex. Government tests found yesterday that small quantities of plutonium, one of the world's most dangerous elements, have seeped into soil outside the plant.
State broadcaster NHK said underground tunnels linked to reactors 1, 2 and 3 are flooded with water containing radiation measured in some spots at a highly dangerous 1,000 millisieverts an hour. Workers in protective gear are shoring up the tunnel shafts with sandbags to stop the water – which reportedly contains concentrations of long-lived caesium-137 – from seeping into the sea about 55 to 70 metres away.
Japan's Nuclear Safety Agency said that the plutonium was "not at levels harmful to human health", but the government's top spokesman Yukio Edano called the situation "very grave", and confirmed fears that at least one reactor had suffered a partial meltdown.
The admission added to pressure on Prime Minister Naoto Kan to widen an exclusion zone around the plant, possibly forcing another 130,000 people to evacuate. Yesterday, a tired-looking Mr Kan faced withering criticism from opposition MPs, who called him "irresponsible" and "incompetent".

Those "huge sums" wont mean a thing when they lose their life to this battle. I think we obviously need people in their doing something, but these people are just 'Suicide squads'...I knew over a week ago exactly how this was going to play out...and nuclear physicists couldn't predict this? It's obvious they can't get a handle on this...not "for years" anyway...they need to come up with something, and quick. Bury the thing, I dunno, there has to be a way to isolate the radiative materials, I don't care how much it's all worth.
