The basic problem with the nuclear power plant – which doesn’t really have that much to do with the earthquake damage, although this laid the foundations for it and was obviously a huge obstacle for them – is that they are dealing with such huge amounts of water at the plant. The water is used to cool the reactor cores which are now being stored on the site, which is obviously highly necessary in a nuclear power plant as those babies are going nuclear – for lack of a better word – all the time and obviously need to be cooled down.
There are currently around 1000 tanks on the site used to cover up the water, but these are only currently at 85% of their capacity, which means that another 400 tons of water is pumped into the power plant every day. Obviously, dealing with such huge amounts of water means that some is unaccounted for and somehow it manages to leak out of the tanks and into the nearby sea.
A guy called Mycle Schneider has also stated that because of the bad infrastructure involved in the plant since the earthquake that there are also cracks all over the plant – ‘in the basement, all over the place’ – which leads to more leaking which can’t actually be measured. So even though the plant admitted to leaking 300 tons of radioactive water into the sea last week the actual amount could be much, much higher. Again, that sounds pretty bad to me.
Reuters made the following graphic to try and explain how the leaked water ends up quickly in the sea and how it’s pretty much impossible to stop it. As you can see, efforts to use a chemical barrier to stop the flow have not worked and they’re currently building a steel wall in its place to try and help out. I’m not really sure how that would help but I assume they’ll be able to monitor the water through the wall somehow for radioactivity and act accordingly to remove it.
So there are obviously some serious problems with the plant ant the situation possibly came to a head last week with the first admission from the plant that they had leaked 300 tons of radioactive water into the Pacific Ocean over a one week period. Previously the plant had generally denied that anything is going wrong there and have tried to create the illusion that it is all working effectively, achieving (or attempting to achieve it as nobody really believed them) through a combination of denial, media blackouts and fudging the science and switching off their radiation sensors.
