Japan PM says Fukushima nuclear site finally stabilised

www.bbc.co.uk

Engineers have brought the crippled Fukushima nuclear plant to a "cold shutdown condition", nine months after the earthquake and tsunami, Japan has confirmed.

Waste water has built up and some contaminated liquid has been released into the sea.

This is where water that cools nuclear fuel rods remains below boiling point, meaning that the fuel cannot reheat.

Tepco has also defined it as bringing the release of radioactive materials under control and reducing public radiation exposure to a level that does not exceed 1mSv/year at the site boundary.

So, do we really trust them anymore?
When it comes down to it, we will probably never know the truth.

Can't do a cold shut down on something that melted through the core That was determined months ago...

At this point I say let them eat GloFish

Exactly, how do you liquid cool matter that has gone beneath the earth?

I'm sure they have a "cold shutdown" because nothing is left at the disable facilities.

How can something go "beneath the earth"? I assume you mean melt through the reactor building itself into the earth? Well, as far as we know, that hasn't happened.

The core itself is what melts, so it doesn't "melt through the core" rather the core melts through the reactor pressure vessel, often out through the penetrations for control rods and instrumentation at the bottom of the reactor pressure vessel, spilling onto concrete floor underneath the reactor itself. Then it can interact with the concrete and continue melting through if it isn't cooled.

Yes, it is possible to cool the fuel debris after they have spilled onto the concrete floor. Which is what Japan did, hence "cold shutdown".

Its fairly clear the only way to cool that bad boy down was to create a mini ice age in a few small metres of earth... Strangley enough thats more believable then everything else they have said

It would be nice to know what is REALLY going on at Fukushima.

My heart goes out to the Japanese people.

It would be nice but at the same time more then likely terrifying.

It’s not just the Japanese but the whole world

True. Even though the contamination/radiation can spread throughout the world, Japan is taking the brunt of it. And it's a small country.

Ya sure cold shutdown. The sad part is the Japanese are such followers they will buy into this and the masses will not say a thing.


Personally I am sick of hearing about how sad it is for them. They are not only poisoning themselves but many other countries. And yet they follow blindly. When will they wake up when they no longer need lights to see at night.



You would think they would put the foolish pride in the backseat when it comes to there kids. 20 years from now they will wonder why there parents listened to lie after lie and did nothing.

Pretty easy when you are talking about a reactor going "meltdown".

I'm tired of dealing with morons tonight, look up "china syndrome" on google.

Idiots.

You are joking right??

The idea that you really think the "China Syndrome" happened at Fukushima, and are calling other people idiots for knowing it did not - that is depressing....albeit par for ATS!

The containment was not actually breached in any of the reactors. Not one, not even a little bit.

Once the nuclear material hit criticality there was no stopping it. All they can do is what the US told them to do in the first place.....bury it.

All that MOX fuel (plutonium/weapons grade) and Uranium in the cooling ponds plus the reactors all went critical.


Fukushima is worse than Chernobyl. You can drive to Chernobyl and look around. You won't be able to walk around the Fukushima Reactors for thousands of years.

Even TEPCO doesn't claim that:

online.wsj.com...

The pressure vessel a cylindrical steel container that holds nuclear fuel, "is likely to be damaged and leaking water at units Nos. 2 and 3," said Junichi Matsumoto, Tepco spokesman on nuclear issues, in a news briefing Sunday.

That's TEPCO saying they have a likely containment breach in two of the reactors, right?

Maybe you meant corium didn't breach containment, but radioactive water did. Hydrogen leaked too. In fact unit 3 failed so badly, leaking hydrogen from unit 3 is actually what caused the hydrogen explosion in #4:

According to Tepco, hydrogen produced in the overheating of the reactor core at unit 3 flowed through a gas-treatment line and entered unit No. 4 because of a breakdown of valves. Hydrogen leaked from ducts in the second, third and fourth floors of the reactor building at unit No. 4 and ignited a massive explosion.

This source confirms the containment breach of reactor 2:

Major fuel melting occurred early on in all three units, though the fuel remains essentially contained except for some volatile fission products vented early on, or released from unit 2 in mid March, and some soluble ones which are leaking with the water, especially from unit 2, where the containment is evidently breached
