Fukushima nuclear fuel debris retrieval to start as early as this month

Good luck for this very challenging and necessary work.

“ as early as this month” early ? 13 years after the accident.

Anyway it will be postponed again. They have no clue what to do

Do you know what to do? Can you do better?

They have no clue what to do

I think that TEPCO, IRID, the IAEA, and all their international partners (including the UK's Sellafield, which has probably more decommissioning experience than anyone else) do have a clue what to do, despite what keyboard warriors may say.

No-one has conducted an operation of this complexity before, so there will be problems and delays along the way. And despite 13 years having passed since the accident:

1) It's better to take the time to do this properly, rather than rush into it and possibly cause more problems

2) A lot of other work has been done in that period: it's not like they've spent 13 years doing nothing

Fukushima nuclear fuel debris retrieval to start as early as this month

.

A large percentage of the radioactive debris has been washed into the sea-that isn’t retrievable.

They will need many more decades, if not longer, to completely remove all the corium.

It's talking about fuel debris, which is the portion of fuel that melted down/deformed following the accident.

As far as I know (though I'm not an expert), "a large percentage" of that has not been washed into the sea, and neither has any other major radioactive debris from the reactors. The fuel has either been removed, or is still inside the reactors.

If you have a source that states the contrary I'd be interested to read it.

An estimated 880 tons that will probably cost the best part of a trillion dollars and 25 years to clean up. And all of those figures will probably go up, and up.

All because of a few cheap diesel generators in the wrong place.

There is no known method for removing the corium with radiation levels of 15 SIEVERTS plus. It could take 100 years. Meanwhile, while the corium remains, it needs water cooling, creating more wastewater.

The absence of safety features extends beyond the emergency generators. The switchgear that controls the power is situated on the ground floor of the reactor building. It was destroyed by the tsunami, preventing the power from the emergency generators from reaching the reactors.

Isabelle,where is the debris gonna be stored,best thing is learn from Chernobyl and just build a frame to enclosed the radiation

Based on "how quickly" TEPCO is moving now LOLZ.

projected to take 30 to 40 years

An estimated 880 tons of radioactive fuel (or something else?) washed into the sea? I've never read anything like that. Again, please provide a source.

(And if you're talking about the things still at the site that need to be cleaned up, that's not what the previous poster claimed.)

Isabelle,where is the debris gonna be stored

Not yet decided, but possibly in Hokkaido or Saga.
