UK's Chief Scientist Backs Nuclear Power Revival 438
Timbotronic writes "The UK government's chief scientific adviser has sent his clearest signal that Britain will need to revive its nuclear power industry in the face of a looming energy crisis and the threat of global warming. In an interview with the Guardian, Sir David King said there were economic as well as environmental reasons for a new generation of reactors." From the article: "His remarks come in the build-up to international talks in Montreal on how to address the threat of climate change when the Kyoto protocol expires in 2012. He denied suggestions - sparked by comments from Mr Blair that he was changing his mind on whether international treaties were the best way to tackle global warming - that Britain was moving closer to the stance of the US, which has refused to back Kyoto-style emission reductions."

Uranium is quite a bit more abundant than is often depicted; remember that at today's U price the cost of the natural uranium itself is a very small part of the cost of nuclear energy, so its price could go up a lot without significant impact. When and if that happens, we can build powerplants with improved breeding to extend the resource even more.
If you can dispute that, please provide a reference for your pesonal residential grid electric supplier you use -a URL is fine- and what the contract terms are
This is the Chicago are; we're supplied by ComEd [exeloncorp.com]. Residential rates are 8.75 cents/kWh (plus a fixed service fee of $7.13/month). There are also taxes, IIRC, but I don't remember what they are.
According to this page [solarbuzz.com], PV electricity is still about 30 cents/kWh in the sunniest locations. Chicago is far from the sunniest location; let's say 50 cents/kWh here. So solar is not competitive with grid power for my by about a factor of five.
Re:Nuclear Power (Score:4, Insightful)
Indeed, we have. And you know what? Solar power is, inflation-adjusted, a quarter the cost it was in the 1970s. In short, the predictions of notably reduced cost have been *accurate*. If they keep remaining accurate, solar will become the cheapest power source available.
The physics are sound, and there are many potential approaches, for not just nanocrystalline solar, but efficient organic solar. Low efficiency organic solar is due to random scattering of the electron donors and recipients. There are at least half a dozen companies out there working on nanoscale assembly, so that it's not random, and thus should get silicon-level efficiency at the cost of plastic sheeting. The odds of none of them succeeding seem extremely slim.
Uranium is quite a bit more abundant than is often depicted
False. For example SK's known deposits will be fully extracted in 25 years (Australia will last loner). At current power consumption and efficiency, if we produced all of our power from uranium, and assuming new deposits are found, we've probably got about as much uranium left as we do coal.
The problem is not only that uranium isn't an incredibly common element on the surface. The fact is that only 0.7% of natural uranium is U-235, which is what is burned in the vast majority of reactors worldwide And you'll usually only get half of that out. What we *really* need are safe breeders (for example, lead or lead-bismuth). Also, thorium breeders allow the use of a completely different, not to mention more common, fuel.
Additionally, there are many types of solar beyond PV; PV is just the most convenient for small-scale application. For large scale, your most economical options are solar thermal and (possibly) solar chimneys (it's a relatively new concept, so it's too early to say). With solar thermal, you don't need silicon - you can use any decent infrared reflector, along with a heliostat, and you point it at a dark-colored tank housing a working fluid. Even if you're just looking a PV, small-scale heliostat arrays that direct light to small high-efficiency silicon cells are just about to start hitting the market, promising rooftop-mounted grid-price PV solar (cheaper in sunnier regions, more expensive in shady regions).
Lastly, solar can displace electricity/natural gas consumption. For example, not only can you have solar water heating and solar house heating, but you can even have solar-powered air conditioning (it's currently only cost-effective for large facilities due to the cost of the evaporators, however, since they're not mass produced).

The real issue is how to deal with varying power. Instead of focusing on power generation, we should focus on how to store it.

There's about 50 years of uranium reserves right now, a bit over 2 million tons.
Reserves are ores that are economically exploitable. In other words, reserves increase when you find a less expensive way to get the ore, or when the price of ore rises. If the price of ore goes up by 50%, we more than double our reserves to 5 million tons. If it goes up much more than that, oceanic reserves [sarov.ru] come into play, and there are 4.5 *billion* tons in the oceans.
Now, that's talking about U235 burned in a PWR. There are other things you can do which vastly increase reserves. There are reactor designs that can breed U238 into U235. That presents a proliferation concern, but you can also just burn U238 in a CANDU reactor or other design. You can breed thorium into U233 and burn that.
And the thing is that nuclear fuel is so much more energy-dense than chemical fuel. Coal has an energy content of about 24 MJ per kilogram, assuming perfect conversion to electricity, and I think good coal plants with top-of-the-line turbines and boilers and everything can get up to about 70% overall thermal efficiency, but hell, let's say 90%. Figures I found for the US in 1982 indicate that all the nuclear power plants in the US consumed 540 tons of fuel and produced 1.1E12 kilowatt-hours of electricity, which means *after* all those efficiency losses (PWRs are less thermally efficient because you've got to transfer heat across coolant loops), we were getting 8 million megajoules per kilogram of fuel.
8 million megajoules per kilogram, versus 21.6 megajoules per kilogram. What that means is that your *fuel* cost can rise significantly, but your cost per kilowatt-hour at your meter will see only a very small rise.
So to sum up, there's a hella lot of nuclear fuel available.

Coal produces large amounts of greenhouse gasses, sulfur- and nitrogen-oxides, uranium, and thorium. The last two are radioactive, the middle two are the largest contributors to acid rain. The amount of uranium and thorium actually adds more radiation than storing the spent fissionable fuels. Add to that the issue of 100s:1 for coal to nuclear for fuel amounts.
In the US, for example, more radioacti

The site you link to - Nuclear Tourist, sheesh the name alone should have given away their bias - quotes the subsidized costs. If you care about the free market then you wouldn't promote a 60 year old fuel source that still can't turn a profit without subsidies.

I would probably replace the word 'better' with 'more reckless', given the population density of the nation... there really aren't safe (ie uninhabited) places to put reactors in Europe. Nuclear seems to make more sense for the US/Canada/Russia/etc.
If you want a model energy grid, look at Iceland's geothermal plants or Denmark's wind generators... not France's half-assed solution.

Coal power much more radioactive than nuclear (Score:5, Informative)
It's physically impossible for a pebble-bed reactor [wikipedia.org] to meltdown. It does not have cooling rods. It does not have heavy water.
Cleaner? Coal and gas give off Carbon oxides and other nasties. Yes this is a problem.
Coal also gives off quite a lot of radioactivity, and it's going straight into the atmosphere. In 1982, US coal power plants released 800 tons of radioactive uranium and 2000 tons of radioactive thorium burnt straight out of coal directly into the atmosphere. Nuclear power plants, as a rule, don't do that. We need to shut down every damn coal plant as soon as humanly possible.
Other coal nasties include sulphur dioxide, the thingie that reacts with water in clouds to drop a lovely rain of sulphuric acid on our heads. Yay!
Oil and coal are obviously bad. Natural gas releases a fair bit of carbon dioxide, and it will run out sooner rather than later if we keep building more plants. Hydroelectric power drowns whole ecosystems. A pretty giant lake where there was no pretty giant lake before is very environmentally unfriendly.
Look, I support solar and wind power. I would support a proposal to make rooftop solar power panels mandated by law for all buildings. Windfarms are a good idea, even if they seem to be evoking silly NIMBYism out of some people. But we need nuclear power in the triptych, at least until we get fusion figured out.
You can't produce a lot of megawatts with solar and wind in a single location without using up a ginormous amount of space. That space isn't magically appearing out of nowhere. Something is being displaced, be it a forest, a field, or some sort of human usage. Nuclear power is relatively compact by comparison. In many cases, the choice is between either compact or nothing.

A coal plant's worst case scenario is a giant smog cloud.
Not to mention tons of radioactive waste. For a given amount of energy out, there is more waste uranium in coal than nuclear power.
A nuclear plants worst case scenario is the permanent evacuation of the highly populated region surrounding Chernobyl, and a significant rise in lukemia rates, etc, etc.
If you use stupid designs like Chernobyl the above is true. If you use intelligent designs that cannot happen. Nuclear power plants are governed by the laws of physics, not your imagination.
But nuclear power gives us all that lovely radioactive waste which quite simply has to be thrown in big holes and the lid sealed up for over 40,000 years!
Only if you are stupid and throw it into a big hole. France doesn't throw their waste into a big hole, they recycle it.
Oh, but oil and gas are contributing to the greenhouse effect! Well yes they are, but does that justify building more reactors,
Well you can go back to a hunter gather lifestyle if you want. I've considered it, and I don't want to. Nuclear power is the only long term solution so long as we remain on earth.
generating more nuclear waste,
Not a problem, see above.
AND more nuclear warheads?
Where did that come from? Nuclear warheads are a very different subjects. Governments that want one will get them, with or withour nuclear power plants.
There' this thing called the sun. Provides loads of energy. The Wind! Water? Is nothing else viable?
Well yes, the sun does provide loads of energy. Most of it is not directed at the earth though. Even then it is hard to deal with. Many question if enough strikes the earth for our use, even at 100% conversion efficiency. 40% efficiency is the max we have got from a solar cell, and to get that much required a lot of special effort which does not scale to large scale production. Everything else is much worse than that.
