Yeah, but you are, and you clearly read my post, so MISSION ACCOMPLISHED, I DECLARE VICTORY.
Aaron you might not have noticed, but, uhh, the main participants in this debate probably aren't equipped to actually parse numbers.

And thats even if you are naieve enough to think that the government will not continue to pay those costs for any new nuclear.
Typical for someone with your views to throw 70 billion of taxpayers money away and learn NOTHING from the lesson.
The Humber Bridge went something like 340% overbudget in the 70s, using your ridiculous logic no bridges should ever have been built in the world again. Or something equally stupid.
The British Government is well known for optimism bias for when it comes to costing projects, so to use examples purely from your own inept government as a foundation for an argument on Nuclear Power in the US/Elsewhere is silly to say the least.
Looks like nuclear power is the choice. A smart move by the US.
The first-gen plants, like the other nuclear weapon powers, were designed to produce weapons-grade material as well as power. This costs a LOT.
The second-gen in the UK was a mistake born of basically screwing the heck up, believing the massively expensive AGR's were the future and not a dead end.
There's only one third-gen reactor, and it's economic even with being first-in-class. And the new plants are a commercial design which are NOT first-in-class. It's not even remotely parallel.
Cliffski is ignoring this, and where the new liability lies (with the companies), because it suits him. Even the Tories think he's wrong on this, however.
Feel free to build US nuclear plants. I don't care, they don't cost me a penny. I can only discuss and debate from my own experience and knowledge, what else would you expect?
You think the taxpayer isn't paying for decommisioning, waste disposal and security for sizewell?
I'd love to know where you read that.
first google result:
Also:Taxpayers will pick up most of the bill because the twin reactor plant, as well as 20 other reactors around the country, are state-owned
Cool! I assume you are factoring in the fact that the land taken up by a nuclear plant is useless for eighty years after power output has ceased? You may not know it, but wind turbines (even large ones) get erected in a day, as do solar panels, and can be removed in almost as short a timescale.Under current plans, all the Sizewell spent fuel will be removed from the reactor by 2013.
Demolition of ancillary buildings will continue until 2034 when the site will be moth-balled in a “care and maintenance” phase – to allow radioactivity levels to subside. Final site clearance work is due to start in 2088 and last for 10 years.
At Bradwell, the “care and maintenance” stage is due to start in 2027, with final site clearance being achieved in 2093.
Just making sure you really *are* taking into account the true cost of nuclear.

My wife and I have friends who live in Koriyama (about 50-60km's west of the nuke plant) and to this day it is still not safe for them to drink tap water or even allow their children to play outside on any exposed soil.
The major issue with having so many nuke plants is that Japan can ill afford disasters like this as it wipes out what little land they have available for what is an already over-crowded landmass especially in coastal areas. But their power usage is massive and without the plants the country would have insufficient power to supply their economy. It's a horrible catch-22 situation.
It looks like there might be some significant external exposure, but a study of 25551 schoolchildren found that average exposure was about 33% over the limit and maximal exposure was ~4 times that (or less than 1 chest ray/year).
So yes, there has been an impact on Koriyama, but let's not exaggerate things.

I'm sure you'll go ahead, skim and misinterpret, but hey!
And that under a coal-fired plant is toxic as shit too. Your point? (This one of the reasons that Battersea Power Station redevelopment plans keep failing) BASE LOAD POWER.Cool! I assume you are factoring in the fact that the land taken up by a nuclear plant is useless for eighty years after power output has ceased?

So would you rather have coal or nuclear?
W've already discussed this and I may have even already posted links in this thread, so I'll just note that the idea that this is a 'dirty secret' that everyone is pretending doesn't exist is wrong. People think about this stuff a lot. Here's an example. Note the 'base load' discussion in particular.Originally Posted by Timex
This is for the US. I don't know about the UK but I expect you'd have to consider Europe as a whole to get a good comparison since the US has to much more landmass and numbers may be drastically different in Europe for all I know.
And in any case it doesn't matter what people think is cheapest or best or anything. The goal is to setup a good system and power grid and let it become as efficiently as possible. I support a modest loan guarantee program in the US for nuclear, and I hope we build some EPRs so we don't have all our eggs in the AP1000. But the scale of nuclear subsidies is overboard.

The only way to achieve base load needs with sources like wind or solar is to create massive storage mechanisms. Such things can be done, but they are either inefficient and costly (huge battery stores), or take up large amounts of space (big raised resevoirs that you pump water into, and release to power generators when the main source isn't creating power).
The larger issue is that in order to store power, that means that you need to be creating way more power than you need when the power is "on". So, when the sun is shining, you don't just need enough panels to power everyone's houses while the sun is shining.. you need all of that, plus enough panels to capture enough power to store, so that it can be used when the sun's down. Based on current numbers, this translates into more than doubling the capacity requirements for those energy technologies, not to mention the additional costs associated with the storage mechanism.
This ends up making these technologies extremely impractical, at least as they exist currently, for base load power production.
And therein lies the dirty secret that the advocates don't want to talk about... basically NO ONE is even pretending like these sources can provide base load power production. Even the most ambitious of the plans for those sources essentially are just using them as minor supplementary sources of power, with coal as the primary fuel source.
With Lynch's example of the crazy town idea of Europe outsourcing its power production to Africa (which, by the way, has to rank up there in the "worst ideas ever" list... It's like charging a psychotic homeless person with holding your housekeys for you while you're at work), they're talking about a TARGET of producing less than 20% of their power through the vast solar array, by the year 2050.
So, the most ambitious plan ever involves not even reaching a fifth of the required power, and they won't reach that extremely low bar until nearly forty years in the future?
If you don't believe in AGW, then this plan might be fine for you. But if you accept that humanity needs to reduce its greenhouse gas output, then this plan is absolute insanity.
In contrast, in less than 10 years, you could retool the energy infrastructure to be powered primarily by nuclear. If you go further and replace fossil fuel powered ground transportation, which we have the technology to do now, with electric powered vehicles, then you will effectively eliminate all major sources of carbon emissions into the atmosphere.
So, in less than 10 years, nuclear provides an answer to carbon emissions.
Alternative energy sources, even four decades in the future, still require massive use of fossil fuels.
If emissions are taxed highly and companies believe nuclear can compete, they will snatch up any dangling loan guarantees and even start building them without them.
See my post above for a more general response to the claims in your post.

It's being seriously discussed, it's not crazy. Some countries would be reliable enough to do it, some wouldn't. Africa isn't a big undifferentiated mass of clusterfuck.Originally Posted by Timex
That post you linked to was interesting, but it demands a very large geographic area to be feasible. I'd also like to see how economical such an idea would be, because I suspect you'd need a massive amount of redundancy in order to assure continuous power. The cost of building all that extra capacity "just in case the weather goes wrong" sounds like it would be extremely expensive. While your poster poo-poos "always on" power, because he seems to get disconnected once a week, I've grown use to my electricity never going down. A black-out event is for me a once a decade affair.
But more than anything I'd be extremely dubious about making my country's electricity grid dependent on the weather. The climate is changing. That's why we care about CO2 in the first place. What if the wind stops blowing in one place, and clouds cover another. What if something even more drastic happened, like Krakatoa blows up and you have 50% of your energy network devoted to solar power while sulphur clouds block out the sun. I wouldn't want something as vital as the energy grid dependent so much on the whims of nature.
I think the only real answer to that is tidal power and, like Timex said, large scale storage. But how many decades is that away from feasibility?
We need a "stepping stone" to get to clean, always-on power and it's either nuclear or fossil fuels.
So why do we need to 'pick' nuclear or agree about any of the cost particulars? I think nuclear won't compete against the ramp of solar and wind in cost. Others think otherwise.
The problem is emissions so tax the emissions to whatever rate we want.
Hell, even coal is a long shot player given a breakthrough in sequestration tech.

Wait, you think I'm joking?
Quaro - No, the problem is both security of supply and externalities, of which airborne emissions are just one. Wind power's noise and disruption of bird migration paths, Coal's coal ash waste and toxic heavy metal seepage, Nuclear waste...
There are multiple ways to increase power uptime. Different power sources, grid setups, capacity overbuilding, generators, giant lazer space batteries, whatever. The ideal distribution is not going to be one particular thing, it's going to be a mix of solutions that naturally emerge from market needs and ameliorate the problem as much as people think it's worth to pay.
We could give every building a million dollar battery setup to increase uptime. Really bad idea. We could pick a particular nuclear power plant and subsidize it ridiculously. Really bad idea. We don't need to pick anything ahead of time here.
Sorry, but that is not the type of place where I would want to be counting on to get my electricity every day.
Regardless, the actual point of statement wasn't that it's a crazy town idea... because, hey, maybe you think it's great. That's cool.
But it still only proposes to generate less than one fifth of Europe's power via those renewable sources, after development for forty years.
Thus, even that extremely ambitious plan for use of solar power, does not even make a dent in the carbon issue. You're still going to be burning massive amounts of coal... even half a century from now.
Simply put, it does not address the problem.
Nothing approaches what happened at chernobyl. The Fukushima reactor didn't freaking explode and throw radioactive blocks of flaming graphite all over the countryside.
http://www.weeklystandard.com/articl...sm_508830.htmlWith such juicy incentives, why won’t private investors finance reactors? In 2005-08, with the strongest subsidies, capital markets, and nuclear politics in history, why couldn’t 34 proposed reactors raise any private capital? Because there’s no business case. As a recent study by Citibank U.K. is titled “New Nuclear—the Economics Say No.” That’s why central planners bought all 61 reactors now under construction worldwide. None were free-market transactions. Subsidies can’t reverse bleak fundamentals. A defibrillated corpse will jump but won’t revive.
American taxpayers already reimburse nuclear power developers for legal and regulatory delays. A unique law caps liability for accidents at a present value only one-third that of BP’s $20 billion trust fund for oil-spill costs; any bigger damages fall on citizens. Yet the competitive risks facing new reactors are uninsured, high, and escalating.
