For weeks nuclear officials wanted to get water into the reactors, of the Fukushima Daiichi plant. Now they’re trying to get it out.
It looks like the problem is that they used salty sea water to cool the reactors. It helped to keep the reactors cool enough, but it created pressure inside the reactor chambers. Now it looks like the three reactor cores have sprung leaks, flooding the basements of the reactors with highly radioactive water. Already 3 people went to the hospital, at least two of them had Beta Burns.
The radioactive water is flooding into the Pacific Ocean. Any further work on the reactors is held up because of the high levels of radiation.
