The biggest problem of 2011 and the Fukushima nuclear disaster is that for the next 25,000 to 50,000 years radiation will leak out there into the oceans of the world

 What do I mean by this? One of the 3 meltdowns in 2011 at Fukushima was reprocessing nuclear weapons grade plutonium. They try not to talk about this much because plutonium has a half life of 25,000 years (which might mean we have 50,000 years of radiation seeping into the sea from the water tables on land now.

And there isn't anything useful long term to do to stop this from happening. And the ocean currents continue to spread this around the world because all the oceans are connected by currents (even the Mediterranean Ocean). So, the point is that radiation will continue there seeping through water tables into the ocean for 25,000 to 50,000 years continually. And technologically there is NO permanent way to stop this at present. (even though they are trying to stop this somewhat at present by freezing the water in the ground to try to stop the radiation from going directly into the ocean. But, if you know anything about water it is going to find some way into the ocean anyway eventually.

Also, my thought is that a melt down might never stop melting the ground beneath it also so it is debatable how deep the thing is after 10 years of melting the ground and going down deeper into the ground there?
