Six Years After Fukushima, Robots Finally Find Its Reactors' Melted Uranium Fuel (gizmodo.com)
An anonymous reader quotes Gizmodo:
Earlier this year, remotely piloted robots transmitted what officials believe was a direct view of melted radioactive fuel inside Fukushima Daiichi Nuclear Power Plant's destroyed reactors [YouTube] -- a major discovery, but one that took a long and painful six years to achieve... Japanese officials are now hoping that they can convince a skeptical public that the worst of the disaster is over, the New York Times reported, but it's not clear whether it's too late despite the deployment of 7,000 workers and massive resources to return the region to something approaching normal.
Per the Times, officials admit the recovery plan -- involving the complete destruction of the plant, rather than simply building a concrete sarcophagus around it as the Russians did in Chernobyl -- will take decades and tens of billions of dollars. Currently, Tepco plans to begin removing waste from one of the three contaminated reactors at the plant by 2021, "though they have yet to choose which one"... Currently, radiation levels are so high in the ruined facility that it fries robots sent in within a matter of hours, which will necessitate developing a new generation of droids with even higher radiation tolerances.
Friday a group of Japanese businesses and doctors sued General Electric of behalf of 150,000 Japanese citizens, saying their designs for the Fukushima reactors were reckless and negligent.

rename the plant as an experimental facility for radiation testing electro-mechanical systems. Like a wind tunnel but for radiation exposure

I'm afraid your numbers are off. The prefecture of Fukushima has about 13,750 sq km. 750 is less than the area of that 20km evacuation circle.
Your point, however, is well taken.
The two questions I have is why was Fukushima still active after 30 plus years? What exactly is the warranty period for nuclear power plants.
I would love to get a 30 year warranty on my car or phone. I see they are trying to sue GE... Who issued permits in Japan for this plant? Typically responsibility shifts to the operator after power plants are completed and functioning well since regardless of design or workmanship you can easily destroy a power plant through incompetence or insufficient maintenance.
It is also interesting that the reactor survived the quake it'self but was essentially destroyed by the tsunami.
There is this concept in liability law called Act of God. The Japan Tsunami qualifies if anything ever did. That event killed 15,894 people in a first world country, and as far as I am aware is the highest death toll event in a first world country in at least 70 years outside of war. The Tsunami wave reached a peak height of 133 feet. That is Biblical level apocalyptic disaster right there.
