"AFAIR there is no currently operating AP100. "

Yes, as usual, nuke enthusiasts/true believers have to claim that, in spite of its retched history, the NEXT generation of nukes will finally be the perfect, fool-proof, absolutely safe technology that can be built so cheaply and quickly that we won't even have to meter the energy! :P

But yes, we should definitely go with nukes, since at any moment those nasty wind turbines might melt down, requiring evacuation of vast territories essentially forever, risk toxic clouds of particles falling over even vaster territories, and requiring vastly expensive clean up that lasts for decades and will never actually be able to clean it up and may at any moment trigger a new explosion that will threaten yet vaster regions....

OK, I'm done feeding this troll/true believer for now.

What really bothers me, and I'm not sure if this is the right thread or not, but nuclear power and nuclear waste management require an organized and expensive effort over a very long time. Considering that BAU is leading us to civilization collapse at some point, quite possibly in the next 50-100 years, we are putting the human race at grave risk. There might be no one to go on maintaining those nuclear reactors, potentially leading to meltdowns and radioactive poisoning of the environment. And even if the reactors are shut down safely, who will maintain all that nuclear waste?
In this regard, wind is risk-free. No maintenance - turbine stops at some point, end of story.

Good point, oren. It may be that nukes are the perfect power source for a race that is always well organized, peaceful, efficient, uncorruptible, ever competent...Oh, and where extreme earthquakes, tsunamis, mega-droughts, super-heatwaves...never occur.

But that is not the world we live in. In fact, it is a very bad fit for the world we actually live in where history and simple observation shows that, even though there are periods in some places where peace and organization may prevail, it is a dead certainty that at some point in every location that coherent condition will break down into:

corruption, incompetence, arrogance, venality, drunkenness, greed, negligence...

further decaying inevitably at some point into discord, confusion, anarchy, war...

Given these unalterable facts, even leaving aside the additional inevitability of natural disaster, made even more certain by escalating effects of GW (aslr anyone?), nukes are in fact among the very worst choices for energy sources one could imagine for the real world of men and history and folly that we actually do inhabit here on this flawed orb.

AFAIR there is no currently operating AP100.
Unless they have a 100% uptime they'll need backup too. And not predictable backup like for wind but 1000mw in a second or two. Wind doesn't need that due to the inherent safely of multiple turbines. 

Assuming your nuclear plant takes 8 years to build, it would be cheaper to build wind now and then buy battery storage in 7 years.

You should reread your reference; the average wind turbine installed in 2013 was 1.87mw. 
It also mentions electricity costs of less than 2.5c/kwh  - even with storage that's hard to match with nuclear.

I used to think the same as you, but I find that the cost analysis swings the other way now.

im sorry, i cant follow anything of your logic above, im sorry, please go and do more research ...

you do know that the uptime of nuclear plants is very high....oh maybe you should do some research...

many AP1000S and next gen are being built right now, you are throwing strawmen ... oh maybe you should do some more research...

also, remember the cost you quote was for the electricity produced NOT the installed capacity...

tsch tsch...
and so it goes

Icefest, good references and impeccable logic!!  ;D ;D

"You should reread your reference; the average wind turbine installed in 2013 was 1.87mw.

Yeah, and the costs just keep coming down on wind and solar, while innovations in storage proceed apace.

Very high is not 100%.
Unless it has 100% reliability and no unplanned outages then you need to have an incredibly speedy dispatchable source ready.

I don't doubt they are being built, but you can't say they are a current technology of they have not been finished. You also can't be sure how long they will take to build until you have built at least one that works.

The issue is that with the cheap price of wind energy produced, your nuclear plant will be running at a loss whenever the wind blows. How can you recuperate those costs during wind still nights and still be competitive with any form of power storage?

May I request that you show me the same degree of respect as I show you?

Mati:
I forgot to ask how you equate ASAP CO2 reduction with a 6-7 year lead time?


As an aside does anyone know if there are any unavoidable CO2 emission in the long term nuclear feed-chain? I imagine the transport and centrifuging could be done electrically, but how about the refining an mining?

I haven't followed this thread, but if you use the "new" Olkiluoto 3 in Finland as the basis for future estimates.
In December 2012, Areva estimated costs to 8.5 billion Euros. More than the Large Hadron Collider at CERN, per turbine. It's estimated to be running in 2018-2020. The construction began in 2005, that's probably 15 years for the construction phase.

Nuclear power is better than coal, oil and gas, regarding emissions, in operation. But if you look back on the five major accidents that have occurred historically and multiply that by the number of new reactors needed to cover the worlds fossil energy needs, you get a really scary figure. If I remember correctly, I think you need well over 8000 reactors like Olkiluoto 3. Consider that Pripjat is still a ghost town and the Russians are not ready with their cleanup yet. And certainly not with the aftermath's of radiation injuries. Even if one picture a perfect world and a decrease in accidents with more reactors, you're still left with the emissions from all of those construction phases.


For me, cutting down my energy use is the first and easy part. The energy I buy comes from wind turbines and I use home built heat pumps together with wind turbines, solar cells and solar hot water heaters. Wind and solar works and have done so for a very long time. Easy, cheap to build nowadays (could have been that fifteen years ago IMO) and won't kill anyone. Ah well, I had a jackdaw that flew into one of my guy wires last year, so I don't have zero fatalities there anymore.

For Finland, emission targets would have been achieved easier and cheaper without building the Olkiluoto 3. The price of electricity for consumers would have been lower without Olkiluoto 3. They became more dependent on Russian gas and electricity with Olkiluoto 3. Development of real renewable energy sources like solar and wind, have lost ground in Finland after the decision to build Olkiluoto 3.

For me, Gen IV reactors seems like a viable option. But then again, since we should have started mitigation fifteen years ago, waiting another three or four decades for something that might not work exactly as supposed is not an option.

Edit, URLs got messed up, had to clean it up a bit.

The IAEA Director General’s Report on the Fukushima Daiichi Accident, along with five technical volumes on this topic by international experts, have just been publicly released. This publication comes ahead of the Agency’s General Conference in September.

https://www.iaea.org/newscenter/news/iaea-releases-director-general%E2%80%99s-report-fukushima-daiichi-accident

"A major factor that contributed to the accident was the widespread assumption in Japan that its nuclear power plants were so safe that an accident of this magnitude was simply unthinkable. This assumption was accepted by nuclear power plant operators and was not challenged by regulators or by the government. As a result, Japan was not sufficiently prepared for a severe nuclear accident in March 2011."

IMA on reddit about the radioactivity dispersion through the pacific ocean:

I’m Ken Buesseler, an oceanographer who studies marine radioactivity. I’ve looked at radioactive fallout from atmospheric nuclear weapons testing that peaked in the early 1960’s, studied the Black Sea after Chernobyl in 1986, the year of my PhD, and now we are looking at the unprecedented sources of radionuclides from Fukushima Dai-ichi in 2011. I also studying radioactive elements such as thorium that are naturally occurring in the ocean as a technique to study the ocean’s carbon cycle http://cafethorium.whoi.edu

Fukushima: Five years after Japan's worst nuclear disaster
Fukushima shook Japan's long-stated commitment to nuclear power. Prior to the disaster, the country's 50 some reactors provided more than 30% of its power, according to the World Nuclear Association, an industry body.

This ended on May 5, 2012, when the country's last operating reactor, in Hokkaido, shut down for inspection, leaving Japan without nuclear power for the first time in more than 45 years. (Two units of the Oi nuclear power plant were briefly restarted in 2012, but went offline again a year later.)

Ditching nuclear power wasn't easy for Japan, forcing the country to import around 80% of its fuel, according to the WNA. Household electricity rates rose 19% between 2011 and 2015, and carbon dioxide emissions spiked.

The moratorium lasted until August 2015, when a reactor was restarted in Sendai, sparking protests outside the plant and Prime Minister Shinzo Abe's residence in Tokyo.

After the plant resumed operation, Abe said that it, and others in the process of being restarted, had passed "the world's toughest safety screening."

Public opinion is still firmly against nuclear and many Japanese politicians and commentators have criticized the government's decision to restart the reactors.

a Little old now but the first time I have seen it.  Pretty damming.

The Chances of Another Chernobyl Before 2050? 50%, Say Safety Specialists

And there’s a 50:50 chance of a Three Mile Island-scale disaster in the next 10 years, according to the largest statistical analysis of nuclear accidents ever undertaken.....

...Nevertheless, Wheatley and co say their data suggests that the nuclear industry remains vulnerable dragon king events. “There is a 50% chance that a Fukushima event (or larger) occurs in the next 50 years,” they say.

Fukushima was by far the most expensive accident in history at a cost of $166 billion. That’s 60 per cent of the total cost of all other nuclear accidents added together.

The team calculate that a Chernobyl-scale event, the most severe in terms of radiation release, is as likely as not in the next 27 years. And they say a Three Mile Island event in the next 10 years has a probability of 50 percent.....

I have not followed this thread from the beginning but want to make a comment.

my background includes MS in solid state and nuclear physics so i do understand the process.

this accident was entirely preventable and the engineering staff had tried to prevent it from happening over the previous 10 years.

they knew that a tsunami would over-top to the sea wall and flood the generators in the likely event of another earthquake.

the engineering staff had recommended to management that a new generator be installed higher up the cliff above the facility.

they had also requested that the power switching station which connected the generators to the coolant pumps be raised above the flood level also.

management finally approved and installed another generator higher up on the cliff.

management refused for another 2-3 years to move the power switching substation because they said they were afraid to provoke the antinuclear protesters who would block them.

so when the tsunami over-topped the sea wall and flooded the generators, the power switching substation was also flooded and rendered useless.

that was why the generator which had been installed to save the plant in this very event was not not able to provide power for the coolant pumps.

also, the plant manager decided, too late, to flood the reactors with sea water in spite of efforts by the president of TEPCO to prevent him from flooding it with sea water.

if he had not done this the meltdown would have been catastrophic and could have involved a criticality event as at Chernobyl.

there was never evidence to support management's contention that they could not get a move of the power switching station approved.

it appears they just refused to accept the engineering staff's recommendation. that is the general nature of management structure in japan imo.

Fukushima Facility to Become Soccer Training Camp for 2020 Olympics
The base for the cleanup of the Fukushima nuclear plant will be returned by March to its original use: the training camp for the Japanese national soccer team.

In a symbolic step in the struggle to contain one of the worst nuclear disasters, Tokyo Electric Power Co. Holdings Inc. will return the J-Village facility -- about 20 kilometers (12 miles) from the crippled Dai-Ichi plant and just 7 kilometers from the current exclusion zone -- to the prefectural government during the current fiscal year, company spokesman Tatsuhiro Yamagishi said Tuesday. It’s also a boon for soccer players who will use the complex as their training base for the 2020 Tokyo Olympics.

Please correct me if I am wrong, but these numbers are inside one reactor.  Nice to have something on FOX though.  530 Sieverts. Wow.  Would be nice to be able to compare that to recently removed fuel rods from USNavy reactors - their higher Ur235 initial levels and longer usage makes for a very intense mixture of radiations, heat and large numbers of transuranics. I am not going to hold my breath to get that number.     

So there is a 2 meter - 6 foot hole - not that surprising, I would guess it is downwards toward bedrock.  Any decent assumption on the event there involves TEPCO and the Japanese government delaying, evading, minimalizing and lying about raw data and the situation. The harebrained scheme to stem groundwater infiltration and the slow removal of the hanging fuel rods are to me greater concerns. 

What makes me petulant is not the slow dribble of data but the continued ranking of the Fukushima event as being less than the Chernobyl event.Yes, I read Yablokov and Nesterenko's  NYAcademy of Sciences #1181  at Nukewatch (they had it for sale) while visiting friends.  It is free to download on the web.  Yes, a lot of people died and people still die each day due to Chernobyl. 

Chernobyl
Consequences of the Catastrophe for
People and the Environment

But being the pessimistic sort, I believe that the damage to the Japanese people, the Japanese ecology and the ecology of the Pacific ocean (many of fission products bio-accumulate) are at least on par with Chernobyl, if not today, well then in a decade. 

Silent on FOX news however was the fact that 20 plus similar GE "Mark I" reactors with the fuel pools high above the ground are still being utilized in the US.  Now to me  that is an emergency that can be reduced.  They  got 40 years production out of most of these prototypes.  They need to be mothballed and the fuel steel dry casked.   Don't hold your breath.  peace out.

Here is a fascinating documentary from Adam Curtis that originally aired in 1992

https://www.youtube.com/watch?v=EviEN0ScOwg

It centers around the GE reactors and includes an amazing interview with Alvin Weinberg, the inventor of the submarine reactor that was used as the base for GE's. In the interview he explicitly says that scaling up the design makes it inherently unstable and impossible to predict whether the safety systems will succeed.

It irritates me to no end that "nuclear power" has become synonymous with poor designs that they knew were impossible to predict even as they were building them, and that by covering up this fact for decades it has destroyed all credibility in the science and engineering.

This was the first time that they were able to measure the radiation level inside the reactor.....  it is not a "new" spike in radiation. 

Here is the press release:

and so it goes

And others agree not really a spike. 

http://www.fukuleaks.org/web/?p=16094

This first sentence is extremely misleading in a number of ways. “Has reached a maximum” has given some readers an assumption that this reading is higher than previous readings for this location. That is not true. This is the first reading ever taken in the pedestal under the reactor vessel of unit 2. You have to have previous readings to claim this one is higher than previous readings. Since there are no previous readings there is no way to claim this is some form of an increase, a “spike” in radiation or in some way higher than before. This also would not be the highest reading since the meltdowns. Higher readings obviously took place, without some method of comprehensive recording there is no data of that to compare the new reading to. Ambiguous wordings seem to have led to a game of telephone where this morphed into rumors of a new problem at the plant.


I have been attempting off and on to find a technically based web site with updated Fukushima updates.  I had enjoyed all posts by Fairewinds and also those by the Union of Concerned Scientists.  but the pace slows down. 

I am pleasantly surprised at my serendipity at finding
http://www.fukuleaks.org/web/  with the above posts.  They give the original sources and nice graphics.  They also have a nice layout and  fast rendering of the html and css code

For me a nice find of graphics and data comparisions is their Fukushima and Chernobyl events. It is from 2013,but -   
http://www.fukuleaks.org/web/?p=11668

These estimate ranges are presented to give an idea of the broad range of official estimates and are not a specific scientific study. What these widely divergent estimates show is that there is a need for more honest and accurate study of this issue.

Fukushima Vs. Chernobyl
We looked at these two disasters since they are frequently compared to each other. The extremely high levels, all in petabecquerels are problematic even if there is a considerable difference between the two.

longwalks1, that's a great find.
great website.

the following is also a great resource:

http://www.unscear.org/unscear/en/index.html

here is their 2016 report on Fukushima:
