Fukushima: reactors lose all water as soon as it goes in

This is just one of the many news I read daily on that brutal nuclear catastrophe of global implications which is Fukushima. I just can't keep up with all but the situation seems to be seriously deteriorating by the moment (or more likely it was all the time that way, just that we were not informed). 

A robot camera descending to Hell... I mean: one of the reactors of the devastated Fukushima Daiichi nuclear site, found barely "inches" of water where there should have been at least 4.5 meters. 

The video published by TEPCO shows that the 400 tons of water injected to reactor 1 go down the drain into the ground as soon as they are poured in. As the Japan Times explains:
The water used to cool the fuel eventually flows into the turbine building, where it is believed to mingle with water intruding from outside. The turbine building is also connected to an underground trench that runs toward the coast. Highly radioactive water from the trench is believed to be mixing with separate groundwater flows before entering the sea.

This does not just happen in reactor 1 but it is probably the case of the three reactors which were active when the catastrophe happened. The storage of "spent" fuel (actually more toxic than "unspent" one) in the reactors themselves, two of which violently exploded, while another collapsed almost completely because of radioactive erosion and seismic movements, only adds to the severity of the problem.

The water flow from the mountains and the tides seems to be entering freely inside the destroyed reactors, incorporating all kind or radionuclides before it goes to the sea. Then it travels quickly across the Pacific Ocean with only limited dilution to the coasts of Canada and the USA. While the Pacific Ocean is really big, it seems not to be big enough to face a single nuclear catastrophe.

Also for sushi-lovers, Simply Info mentions that South Korea is banning more and more fish and seafood imports from Japan because this country does not control the radiation levels of its produce.
