(Christopher Busby) -- I recently pointed out, this operation has to go on forever - a long sickness, but at least not a sudden death. However, this week begins a new development in the potential sudden death department.
There is a curious and bizarre reversal of the natural at Fukushima: a looking-glass world inversion. Unlike the standard marine catastrophe, for example the Titanic, where the need is to manically pump water out of the ship to stop it sinking, at Fukushima the game is to madly pump water in, in order to stop it melting down and exploding.
Probably because it is now clear that the saturation of the ground from all the pumping water for cooling the several reactors and spent fuel pools has destabilized the foundations of the buildings, TEPCO is bringing forward its operation to try and deal with what is perhaps the most dangerous of the four sites, the spent fuel pond of Reactor 4. For this pond contains a truly enormous amount of radioactive material: 1,331 spent fuel grids amounting to 228.3 tons of Uranium and Plutonium buried inside a swimming pool which has already dried out once and exploded. That explosion blasted a significant, but unknown, quantity of lethally radioactive bits and pieces of fuel element around the site (where I heard they were bulldozed into the ground - who knows?), but it also blew the top off the building, covered the fuel elements under the water with rubble and pieces of crane machinery, and no doubt twisted and melted a large proportion of the remaining spent fuel.
The operation involves the kind of game that we are all familiar with in those machines in penny arcades. You know the ones. You stick in some coins. You have levers which manipulate a claw which you position over a teddy bear or a doll and then you let this down, pick the item up and drop it down a chute to win it. In the TEPCO version of this game, you build a crane over the spent fuel tank (or what’s left of it) and manoeuver a grab down into the rubble to deftly pick out a spent fuel assembly, like a 4.5meter long and 24cm square birdcage containing the zirconium metal clad fuel elements, each unit weighing about one third of a ton.
Of course, to make the game more interesting, they are not just sitting there like they were when the tank was being used. They are under water (sea water), covered in debris, corroded, busted, twisted, intertwined and generally impossible to deal with. And here is the really scary thing: if you manage to bust a fuel element, the best outcome is that huge amounts of radioactivity escape into the air and blow over Japan, just like before. The worst outcome is when two of these things get too close, perhaps because in pulling one out it breaks and falls against another one in the tank. Because then you suddenly have lots of fission, a lot of heat, a meltdown, possibly a big blast like before, and the destruction of the entire cooling pond. Or else the water boils off and the whole thing catches fire.

Then what happens? Not quite Armageddon, but as far as Japan is concerned, almost. I bet they have contingency plans to evacuate the northern island to Korea, China, anywhere. A lot of this radiation will end up in the USA, a long way downwind, admittedly, but then there is an awful lot of radioactivity involved. Continue reading via RT.com . . .
