At the crippled nuclear power plant in Fukushima, leakage of contaminated water was reported recently. One hundred and thirty tons of highly contaminated water was leaked from a reservoir. Those resorvoirs have only 3 layers of sheets as the wall, they say. Only 3 layers of sheets! There are 13000 tons of such water reserved in tanks as well as reservoirs at present. Four hundred tons of contaminated water are brought about from the plant every day. The amount of reserved water with radiation is continuously increasing. There could be much more leakage of polluted water from those reserved in the fragile reservoirs than reported this time, I suspect.
The melt down fuels are unknown in detail at all. They could penetrate the casing of reactors below the destroyed reactor. We should expect pollution into the water underground and eventually into the ocean. The melt down fuels are still totally inaccessible now. All they are doing now is to cool them blindly with water.
The numerous used fuels are still being pooled. Especially, in the pool of 4th reactor, there are more than 1300 of used fuels being cooled. The 4th reactor building is half detroyed by the explosion of the other reactor buildings. It could fall down by any quake etc that results in scattered used fuels on the ground. At that situation, since those used fuels out of water are highly radioactive, the plant could become inaccessible.
Most importantly, there are still 150000 evacuees from the area adjacent to the plant. Most of them would lose their homeland forever, I am afraid. Hundreds of people have already died among those evacuees. Over half of them are reported to have died of the causes related with the stress or any illness due to long lasting evacuation. There should be more numbers of workers at the plant being irradiated from ow on. They might have problems of chronic radiation in the future.
The accident in Fukushima has never ended yet. We have not found even the exit to solution.
