Fukushima operators send robot into worst-hit melted reactor

It just 11 years too late.

Actually, it's good news. At the time of the accident, they had nothing that wouldn't conk out right away. This is progress.

In other news,

The plant's operator, Tokyo Electric Power Company Holdings, said the submersible robot was sent into Unit 1's primary containment vessel to install a guiding path for five subsequent robots, which will attempt to asses and take samples...

Pretty sure you want don't want "asses" in your article....

And despite all of this, Japan is switching it's old nuclear plants back on. Just how bad does it have to get before people recognise the costs of nuclear power always dramatically outweigh the benefits?

What’s your solution?

Destruction of forests and lands to set up millions of solar panels (which actually should be on every new house

Great! Japan is always 10 to 20 years behind the rest of the world. So yeah! Fukushima is still being fixed by the inept Japanese Government in 2022. Great job!

And to think, all this could have been avoided if they had taken the advice they were given by a French team of experts in 2002 to move the back up generators onto the roofs of the housings to ensure they could not be flooded.

Instead of sending men into space for the rich man club use those rockets to send the nuke water into orbit. The sun will take care of it. Might be a better option.

I bet one rocket could send about 0.000001 of the nuke water. Besides, you would be putting other harmful chems into the atmosphere in order to destroy other harmful chems. If it crashed into the ocean though, it would at least be a little further off-shore from Japan.

Yes, I wonder how many layers of led they had to put around the newer robots. Plus, I wonder if they had to clear out all the conked out robots first that were in the way. I'd like to see the video footage.

take samples of the melted fuel that emits fatally high radiation.

into the environment and we try to force people to eat food products from there?

Just how bad does it have to get before people recognise the costs of nuclear power always dramatically outweigh the benefits?

(according the NPP design), construction cost, running cost, maintain and upgrading, security, disaster measures, fuel, decommissioning and storage of spent waste in secure locations for about 1000 years…

THE COST 10X THE AMOUNT OF POWER GENERATED IN THE LIFETIME

This should be a government mandate. I have just bought a new house and really wish they had installed solar panels.

I agree with you zichi. I am an ME with a specialty in nuclear power. I designed power systems for nuclear plants in the late 1970’s. It was staggering incompetence on the part of TEPCO. There is no excuse or rationale to answer away the failure of due diligence. Engineering is about anticipating risks, not the P&L of TEPCO.

It’s criminal, not a civil issue.

will take at least 50-100 years to resolve even if that is possible.

Centuries more like. TEPCO should entomb the reactors in mountains of concrete and then petition UNESCO to give the site world heritage status.

This isn't a movie.....water is heavy, it's unlikely that they have a rocket powerful enough to send all that water into space......even before you add on the weight of the lead lining needed to stop the radiation from bursting out whilst sitting IN the rocket. Also, you want to strap explosive material to the bottom of the this radioactive super soaker and risk the whole thing exploding on launch, which is a fair possibility, spreading it's highly radioactive contents into the air over a vast area.....yeah...great idea. Maybe they should just beam the water into the sun.....seems just as likely to happen

The problem is that nuclear power tech in the U.S in particular has always been a by product of weapons tech. Countries which did develop commercial reactors, such as the Canadian CANDU and British AGR, did so at tremendous expense. That, coupled with Japan being in the pocket of the U.S. meant that the cheapest, crappiest tech available was the one that got installed. Still, the Americans cannot be blamed for TEPCO’s choice of venue for the reactors.

Well placing a nuclear power plant next to the coast on a island that is known for tsunami was there fault for not taking that into consideration

@zichi is right. They didn’t do it because the cost transporting the material which came mostly by ship was more expensive. They also downsized a lot to cut cost over safely.

-2 ( +0 / -2 )

Another option since they said the nuke water are considered diluted at reasonably safe then just boil the water and let it evaporate and the wind will take care of the rest

@Farmboy,

At the time of the incident in March 2011,they had to beg France and the US for robots,this in spite of Japanese robots supposedly being the world's best.

Turns out that most Japanese ones are either employed on the production line or for cutey duties like ASIMOV or the one SoftBank used which was nothing more than a glorified iPad.

in March 2010 even.
