On Thursday, the Tokyo Electric Power Company (TEPCO), the investor owned utility that operates the Fukushima reactors, reported that it detected a radiation level of 530 sieverts per hour in the containment vessel of reactor 2 at the Fukushima No. 1 power plant.
TEPCO had planned to deploy a remote-controlled robot to assess conditions inside the containment vessel.
The robot is designed to withstand exposure of up to 1,000 sieverts. Based on the calculation of 73 sieverts per hour, the robot could run for more than 10 hours, but 530 sieverts per hour means it would be rendered inoperable in less than two hours.

Over the years so many Japanese have willingly given their lives for the Emporer and Japan....Where are those types nowadays.?
Man the # up, Get the overalls on and get the # in there and clean this mess up....if not for the emporor, then do it for Japan at least.

Even a brief exposure to 530 sieverts of radiation would kill a person.

Three pairs of overalls then. Someone has to fix it. They cant just keep looking down the bloody hole. It's not the local council dealing with a collapsed manhole we are talking about here. This is serious. A game changer. They are leaking into the pacific every minute of every day. We need water, clean water. Our water comes from the sea. All of it.
Has anyone from Tepco fallen on their sword yet..? If not then three pairs of overalls it is.

The tech does not currently exist to get close enough to the material itself do anything lengthy.
Define lengthy...1 week? 5 days? 24 hours?

"Hey you know what sounds like it would be awesome? A bunch of nuclear reactors, with their pools perched a hundred feet above the ground, in poorly constructed buildings, with no plans or structures to contain spent rods, right on a fault line, right beside the ocean. You guys in?"
The whole thing was a horrible idea from the start.

I don't know if that would translate to insta-death, but I imagine someone would be incapacitated damn fast. The robotics certainly are.

This. So much this. If I were the chief engineer on this project, I'd bring back harakiri so I didn't have to think about how badly I'd #ed things up.

Fumiya Tanabe, an expert on nuclear safety who analyzed the 1979 Three Mile Island nuclear accident in the United States, said the findings show that both the preparation for and the actual decommissioning process at the plant will likely prove much more difficult than expected.
“We have few clues on the exact locations, the sizes and the shapes of the nuclear fuel debris,” he said. “The planned investigation by the robot needs a rethink. Work to decommission the plant will require even more time.”
TEPCO said it will need 30 to 40 years to complete the decommissioning process. The utility plans to start work to remove the melted nuclear fuel at the No. 2 and two other stricken reactors in 2021 after deciding on a removal method in fiscal 2018.
TEPCO has yet to determine the location and the condition of the melted fuel in the other two reactors.
