Ya think???!

I guess zakuza are no nuclear experts after all. Who will TEPCO turn to next!?

Hope for the best and only prepare for the best... too bad Murphy is never far behind!

1 ( +4 / -3 )

So, with 54 nuclear reactors, Japan thought they would never have to decommission any of them? No one was trained for this inevitability?

8 ( +11 / -3 )

Another day more incompetence revealed, I wonder does this process go to infinity in Japan???

The mind numbing stupidity on display is truly despicable.

Once again I am having dreams & wondering if I should have left after 3/11, DAMN YOU tepco!!

Unlike the U.S. and some European countries, Japan has never decommissioned a full-fledged reactor.

Were the nuclear reactors in Three Mile Island and Chernobyl decommissioned? Where are those EXPERTS in the US and some European countries? If there were experts who could contribute anything at all to melted down reactors, TMI would have been cleaned away decades ago. This article is a product of either superior complex of whites or inferior complex of Japanese.

Reactors don't need to meltdown to be decommissioned Duh.... Nihon needs to consult with experts on Decommissioning nuclear reactors and by all means follow the advice of the experts. That is all..

How is this not a state secret?

It's not this generations problem wasn't the previous generations concern it's upto the future generation to resolve these issues as always.

Yeah and at one point the US and France didn't have any decommissioning experience either. But of course they had all those serious mistakes when they did their early decommisionings. Oh wait, they didn't have any serious problems.

But when the US had to defuel the melted down TMI they had all those serious problems. Oh wait, they didn't have any serious problems.

Too bad no one has ever written any papers or guidelines on decommisionings or TMI's defueling. Oh wait they have.

Yeah time for the 'experts' to find something else to spread FUD about.

Ah! that's why, make sense. (easy answer)

0 ( +0 / -0 )

The original AP article digs deeper, claiming that the US has 20 nuclear decommission experts with a collective 200+ years of experience. France has 10+, whereas Japan has ONE. They need help.

Also interesting was the fact that Japanese experts helped with the decommissioning of Three Mile, but are now in other fields and cannot be reined in to help.

3 ( +4 / -1 )

The one expert in Japan probably is keeping out outside help so he can have all the control.

-1 ( +1 / -2 )

This is probably the fourth or fifth article stating Japan's lack of expertise and capabilities of successfully decommissioning this plant and nothing has changed after nearly three years. I am sure there are people within the Japanese nuclear industry that have the education to tackle this debacle, but experts don't come cheap and TEPCO's penny-pinching mind set is why they are floundering.

-1 ( +5 / -6 )

I am to sure that there are any such experts. I mean how many nuclear melt downs have been cleaned up?

Care to name one. TMI has not been cleaned up yet, Russian has not done it yet, so where do we find experts for such a thing?

-3 ( +1 / -4 )

Japan lacks experts for Fukushima, period.

Reactors are designed to run for 30~40 years, they become cash cows after 20 years, and utilities have a number of strategies (some dubious) to extend their lives to nearly 60 years, to obtain the most profit. They are supposed to put sufficient money aside to pay for decommissioning during their operating life, unlike most infrastructure projects which require capital investment during the building phase only. You can be certain that most Japanese utilities do have not sufficient funds to decommission all of their reactors.

Decommissioning is typically poorly planned, with massive cost overruns from unanticipated problems, and highly lengthened time frames, and that is just for reactors that were shutdown in an orderly fashion. Imagine the process with 3 melted reactor cores. Technology does not currently exist to manage these, even the laser cutters and robots used in the UK would be fried by the radiation present in Fukushima Daiichi 1~3.

Toshiba, Hitachi and Mitsubishi, who built these 6 reactors in cooperation with General Electric, are anticipating big business in the future for decommissioning around the world (and Japan?) and are strengthening their resources and capabilities.

@wanderlust

Fascinating! Thank you for the insight!

Just a correction but it's Ukraine, not the Ukraine. The former is the name of the country, the latter was the diminutive name from the USSR era for the area. Most writers post-USSR stop saying "the Ukraine" and properly use "Ukraine".

2 ( +3 / -1 )

So they build them, make huge profits, and have absolutely no idea at all about how to shut them down? How to deal (obviously) with an " incident". Where to put the waist? I am totally on board with paying extra so they can fix this....oh I have been! For 30+ years? But they have no idea??? And the evacuees are still in temporary housing? Damn it , stupid China.

zichi: "According to the law, power companies are suppose to set aside sufficient funds to decommission their nuclear reactors at the end of their life cycle. Big power companies like KEPCO have already admitted that they haven't done that."

And despite not abiding by the law no one is being held responsible, and as such, and given the fact they can expect and receive HUGE government bailouts, why would they ever bother abiding by the law?

4 ( +7 / -3 )

It's not just Japan that has problems, both the Nuclear Regulatory Commission in the USA, and the European Commission (back in 2008) are concerned with decommissioning funding shortfalls, Europe has 150 NPPs to decommission over the next 20 years, at current estimated costs of between US$400 million to US$1 billion each.

Other countries and regions with newer NPPs, it's probably not even on their event horizon.

Very broadly speaking, there are three main ways to decommission a nuclear reactor. The first option is to remove the fuel, disassemble the surrounding structure and find a safe place to store all the different radioactive bits. One problem with this option? Not every country currently has proper waste facilities set up.

Secondly, workers could simply take out the fuel, drain the plumbing and then lock up the reactor, letting the isotopes decay until the plant itself is less radioactive. After 10 to 80 years, the whole structure will be easier to dismantle, but security and maintenance of a decaying structure are issues. The third option, meanwhile, is to bury the reactor in a “tomb” of concrete and hope that no one cracks the structure open for the next 1,400 years. The U.S. Department of Energy took this approach for two old reactors at Savannah River in South Carolina.

These complete costs and issues are usually not included during discussions on the actual cost of nuclear power, the nuclear village do not like to upset the gravy train...

"Stable shutdown"? Is that the same as a "cold shutdown"? Then, all is good. Noda said it was in cood shutdown a long time ago.

Seriously, does this country have any idea of what it's doing? To me they all act like jesters, frantically trying to divert peoples attention from this mega-failure. Fess up instead. Do it again. Do it right.

4 ( +5 / -1 )

@knox harrington - PM Noda's definition of cold shutdown is very different to the international definition of cold shutdown -defined by the US Nuclear Regulatory Commission as the term used to define a reactor coolant system at atmospheric pressure and at a temperature below 200 degrees Fahrenheit following a reactor cool down. The NRC does not define stable shutdown.

It was made for political purposes.There are no stable reactor coolant systems at NPPs 1~3, as evidenced by the continual leaks, plastic piping, power outages, etc..

Sorry Zichi

The article is misleading for as my link indicates, the set aside funds that the law mandates are disbursed to a third party (NUMO) which all of them did. The shortfall, is as a result of lack of "tax" due to for obvious reason, the shutdown of NPP.

Japan lacks nuclear experts period. Fukushima proved that. The workers didn't have a clue when the plant was in trouble. They never went through any safety drills that tested the protocol so that the workers can see, feel, and hear the consequences. The regulators did not seem to have a clue on how a nuclear plant operated. The government had response but let the operator fix the problem. The fixes the were recommended by the 3 mile Island incident were never implemented in Japan. The government never required or recommended anything. It seems the government, the regulators, and the operators just assumed that nothing can go wrong. No need for drills, no need to modify, this is Japan and nothing will happen here.

@ka_chan, so you believe that somehow after the earthquake the plant operators had enough time to move the generators out of the path of the tsunami? Yeah, sure.

Is radiation levels outside the immediately affected zones a legitimate concern? Like if you live in Tokyo for example. I ask because I don't know which source to believe. The J-gov on one hand says it's entirely safe, and on the other hand there are (fear mongering?) reports that even Tokyo will be unsafe in a few decades.

-1 ( +1 / -2 )

Oh pleeeeeaaase don't let TEPCO do this...bring in the US and EU decommissioning team to do this. You have all of our lives in your hands!!

SPEEDI gave TEPCO and the local Govts of Fukushima a 4 hour window IF they had been notified and given SPEEDI's predictions. YES TEPCO would have had the chance to move the back up back up generators indoors and out of harms way.

Some one should hang for keeping SPEEDI's predictions out of the loop.

I will send a letter to J Govt to tell them to stop fear mongering with reports of hot spots as far away as Chiba after the accident to make you feel better.

Then either you are wrong or SPEEDI is ignorant. First the back up generators where indoors. Second the back up generators are huge machines that are bolted to their foundations. It would take days and huge cranes to move them. Then the high voltage cables would have to be rerouted and reconnected. Then the piping for their fuel would have to be rerouted and reconnected.

Anybody who believes that it could be done in 4 hours needs a large dose of reality.

NUMO (Nuclear Waste Management Organization of Japan) is not in the business of nuclear reactor decommissioning

Nobody said they were. The fundamental point is that it's in a form of escrow and is accumulated based on electricity generated per NPP. You simply cannot criticize the power companies for the shortfall when the reason behind it is the almost complete shutdown of NPP based on, for the most part, ex post facto requirements.

-3 ( +0 / -3 )

The power companies are faced by three major financial problems. The long term safe storage of spent nuclear fuel and nuclear waste which NUMO is trying to solve and the funds given by the power companies is short of ¥2.2 trillion.

Thanks to the stoppage of NPP where such levy cannot be collected. KEPCO's shortfall is directly as a result of them not operating and/or operating below their expected annual capacity.

Hence, the issue now is to calculate the levy based on the new stricter standards and how the said allocation (XXX yen per kwh) is cost effective as opposed to other sources. Simply throwing out big numbers when the power companies in Japan itself generates a annual revenue of combined 20 trillion yen is simply misguided.

-3 ( +0 / -3 )

You seem to not understand, the ¥2.2 trillion shortfall in funds to NUMO is from all the power companies with nuclear power. It will cost ¥3 trillion to build a safe storage for the 15,000 tons of nuclear spent fuel by 2020. You also seem to not understand why the gov't and NRA took the decision to shut down all the reactors? Many members of the LPD don't want reactor restarts until after the 2016 general election.

This is how the amount of collection is determined.

http://www.rwmc.or.jp/organization/img/2010img17.jpg http://www.enecho.meti.go.jp/denkihp/bunkakai/seido_sochi/1th/shiryo6.pdf http://www.enecho.meti.go.jp/rw/docs/singikai/shobun/1/010419-04-2.pdf

In other words, the revenue stream is primary based on the power output of NPP. To reach that goal, they need to be operating.

You're essentially two faced. While you cry and scream about the "shortfall" at one end, you also advocate the stoppage of NPP which basically kills the ability to fund this shortfall.

In future the cost of power from nuclear energy will be higher than in the past. If the power companies are producing annual revenue of ¥20 trillion then they should be paying some of the costs of the nuclear disaster which will use up ¥25 trillion over the next 10 years.

There you go again. You want them to pay but you don't want them to operate NPP where they can at least have the ability to raise these funds by setting new allocation amounts.
