So TEPCO sent in a robot that was supposed to be able to function in such high levels of radiation to inspect the No. 1 reactor and help them figure out how to extract the melted fuel, but that didn't work -- probably because they're flying blind and no one is willing to admit it:
The plant’s operator, Tokyo Electric Power (Tepco), said the robot stopped moving on Friday during its first inspection of the containment vessel inside reactor No 1, one of the three reactors that suffered meltdown after the plant was struck by an earthquake and tsunami in March 2011.
Okay, I'm only human. I can't resist reminding the many readers who "explained" to me how crazy and paranoid I was to think there was an actual meltdown. Just sayin'!
Tepco, which recently conceded that the technology for robots to retrieve the nuclear fuel had yet to be developed, said on Monday it would cut the cables to the stranded robot and postpone a similar inspection using a separate device.
Developed by Hitachi-GE Nuclear Energy and the International Research Institute for Nuclear Decommissioning, the robot was supposed to be able to function for about 10 hours even when exposed to radiation at levels that would cause ordinary electronic devices to malfunction.
The “transformer” robot, which can alter its shape depending on its surroundings, was sent in to photograph the inside of the reactor containment vessel and record temperatures and radiation levels.
The remote-control survey robot stopped functioning inside the damaged reactor vessel during the mission but the robot recorded captured images and collected data, including on radiation levels inside the vessel.
It had covered 14 of 18 locations when it stalled, about three hours after it began its journey around the vessel, officials said, adding that they had yet to establish the cause of the problem.
More than four years after Fukushima Daiichi suffered the worst nuclear accident since Chernobyl a quarter of a century earlier, radiation levels inside the three reactors are still far too high for humans to enter.↓ Story continues below ↓
Tepco is pinning its hopes on a new generation of remote-controlled robots, the first of which will monitor the state and location of the melted fuel before others remove it from the reactors’ outer containers.
Last year the dangers posed by high radiation forced Tepco and the government to delay the planned start of fuel removal from reactor No 1 by five years, to 2025. Decommissioning Fukushima Daiichi is expected to take at least 40 years and cost tens of billions of dollars.
Dale Klein, a former chairman of the US nuclear regulatory commission who now advises Tepco, said dangerously high radiation inside the three damaged reactors had made extracting the melted cores particularly difficult.
If it wasn't all so horrifying, it would be funny. Because nothing works. So they just cover things up, as we've seen before. It's all a natural consequence of regulatory capture:
