There are almost countless reasons why Fukushima is such a balls-up.
Tokyo Electric Power Co (TEPCO) owned and operated the complex, and they have remained in-charge of matters from the time it got stuxneted to two-and-a-half years later and now.
Long past are opportunities where the damage and danger could have been minimised. For example, there has effectively been no evacuations from even a few tens of kilometres from the stumps of the reactors. Tens of thousands are still living in shipping containers converted to evacuee housing. These would be folks whose homes were washed away and also were right next to the smoking remains of Dai-Ichi.
TEPCO has done everything on a budget - after all they are a for-profit corporation, and corporations are there for the profits. TEPCO, through their whores in positions of government, have directed the public's money to (allegedly) finance the clean-up and repairs around the wrecked reactor plant. This is how it goes:-
TEPCO gets billions to hire workers. They pocket their share and sub-contract to one of their affiliate companies. The affiliate company pockets what they see fit and re-sub-contract to another 'friendly' company. This new company does precisely the same thing, and six layers of sub-contracting is the norm rather than the exception.
In the end, TEPCO can honestly say they have no idea who the workers at their plant are, and as such they can avoid responsibility for any mistakes they make, and cast the blame on one of the companies they sub-contracted to. When the blame needs to be pinned down, it turns out like a merry-go-round with everyone blaming the next person, and the process grinds to a halt and no one can blame anyone and no one is held responsible.
The workers at GZ are mostly unskilled day-laborours who are preferred because they are societal outcasts and don't posess ID. These people can and do vanish. They are conned into believing they are being hired for construction jobs in Tokyo with a good wage and then get sent by bus up North. But the bus doesn't stop in Tokyo and heads another 180kms North to the Fukushima Dai-Ichi power station. Once there, they are forbidden to talk to reporters and live, work and socialize within the compound. The company that press-ganged them have specially cut sheets of lead to cover the (mandated) radiation testers they keep in their pockets.
All the actual work is ordered by TEPCO staff sitting at monitors well-away from the hot spots, and the unskilled bums often cock up their jobs because they are doing (for example) electrical installation work and have never been trained to do it.
The tanks allegedly holding radioactive water and waste were built on a budget of course. They put the work out to tender and the cheapest quote gets given the job. That's why they are leaking now despite being brand new and are highly unlikely to last more than a few years, and even that doesn't matter because in actual fact the tanks are full and there is a continuous flow from the reactors to these tanks and out the overflows straight into the sea.
The internet here is scoured by a government agency set up after Fuku with the specific job of controlling what info is printed. The same agency also has an army of shills posting on forums trying to prevent debate on what is going on up in Fukushima.
The news rarely ever mentions Fukushima, and if it does then it's for some positive-sounding pack of lies.
Although millions of Japanese are sure to go down with cancers and other ailments as a result of Fukushima, unfortunately the number of people with radiation-related problems in the States is likely ten times worse than in Japan because to put it simply, you lot in the States get just about all of the radiation continuously spewing out of the sabotaged reactor complex. In Japan, only the area immediately around Fukushima (including Tokyo) is highly radiated.
The rain often brings elevated radiation counts here where I am, and the sea current will make this place unsafe for fishing in about six years.
The J gov is doing everything it can to spread the radioactive detritus all over the country and is using our tax yen to transport Fukushima's radioactive refuse to far-flung regions of Japan where it is incinerated by private companies - who get a pretty penny for it c/o TEPCO's whores in gov's generosity with the citizens' tax money (which has ballooned recently).
Roads all over Japan are getting radioactive asphalt and building and garden materials are deliberately being made with Fukushima's radioactive waste. Apartment buildings all over Japan have been discovered to have much higher than ambient radiation due to using concrete with Fuku waste.
Japan is being ever-so generous to third world countries these days and is shipping over huge quantities of radioactive fish and farm produce to fulfill its obligations towards overseas aid.
Lovely people running the nation.
I am acutely aware of the plans to try to haul out the rods in SFP4. I am also under no illusions that the people they are hiring can do the job without cocking it up. For a start, some of the rods are partially burnt and some are deformed. It's a clusterfuck of epic proportions and probably never matched at any time ever in history.
Olympics in Tokyo? Anyone that believes that is on the doctored Kool Aid.
Glazed eyes? OK then, move along - just keep shopping - baaa baaa baaa.
