Nuclear power is very clean compared to any power source that burns fuel. The US has missed several advancements in nuclear technology.

The problem with that argument is it only demonstrates the scope of our energy needs. It says nothing about the feasibility of nuclear versus other technologies, and ignores the fact that the exact same challenge applies to any energy source. To cover our needs with just coal (currently 25% of the world energy supply and something like half of the electrical supply) would similarly require about 10,000 coal plants. You want to it with wind? You need roughly one million of today's highest capacity wind turbines. Solar? About $20 trillion dollars worth of solar panels near the equator will do it. Hydro? Well...forget about that one. Hydro power options are mostly in use in developed countries.
We'd run out of nuclear fuel in decades (actually, I've been told centuries) if we continued to utilize it as poorly as we currently do. Reprocessing, however, can dramatically increase the available energy from existing fuel and potentially the economics of developing new mines. Not to mention reducing the waste by 90% or so.

Case Study: The Side Effects of a Coal Plant
A 500 megawatt coal plant produces 3.5 billion kilowatt-hours per year, enough
to power a city of about 140,000 people. It burns 1,430,000 tons of coal, uses
2.2 billion gallons of water and 146,000 tons of limestone.
It also puts out, each year:
10,000 tons of sulfur dioxide. Sulfur dioxide (SOx) is the main cause of
acid rain, which damages forests, lakes and buildings.
10,200 tons of nitrogen oxide. Nitrogen oxide (NOx) is a major cause of
smog, and also a cause of acid rain.
3.7 million tons of carbon dioxide. Carbon dioxide (CO2) is the main
greenhouse gas, and is the leading cause of global warming. There are
no regulations limiting carbon dioxide emissions in the U.S.
500 tons of small particles. Small particulates are a health hazard,
causing lung damage. Particulates smaller than 10 microns are not
regulated, but may be soon.
220 tons of hydrocarbons. Fossil fuels are made of hydrocarbons; when
they don't burn completely, they are released into the air. They are a

Separate out the short lived waste isotopes, put the long lived usable fuel isotopes back in the reactor. You use the old stuff because while it's still radioactive, it's much less so than stuff fresh out of the reactor, so it's easier and cheaper to handle.

Not necessarily. People say, "let the market determine whether nuclear is cost-effective." The market in the U.S. already did decide, and it said it was not cost-effective. That's why no new plants have been built since 1974. The only reason we're building them now is because the government is heavily subsidizing it. (And, need I add, this says nothing of the cost of waste disposal which is another problem altogether...)
The biggest cost of nuclear is the up-front capital cost of construction and working with government regulation and oversight. Therefore once you have the plants built, it is in the owner's best interest to utilize them to their maximum potential. This doesn't mean that new nuclear power is competitively priced, however.
You will hear the nuclear industry (as well as the U.S. government) touting a 1.8/kWh figure as the cost of nuclear energy, but this figure only refers to the operating costs of nuclear and DOESN'T include the capital cost of building a nuclear reactor itself (which is the biggest part), nor does it include the cost of decommissioning a reactor when it is finally retired. This also says nothing of the fact that uranium prices have more than tripled in the last few years. If we're not going to include capital construction costs when describing the cost of nuclear energy, then why should we use a different standard for measuring energy costs for other technology such as windmills? Wind suddenly become extremely cheap (less than 1/kWh to maintain) if you exclude the capital construction cost.
What killed nuclear in the U.S. was regulatory cost. That changed with President Bush's 2005 Energy Policy Act included several billion dollars of incentives to the nuclear industry, for instance guaranteeing that for the first six new nuclear plants constructed, the U.S. government will pay for any cost overruns (up to $2 billion). This means it's a no-brainer for the nuclear industry - they get paid even if the same kinds of regulatory delays that killed previous plants creep up for these new plants. In addition there are huge tax credits for the first eight years of operation.
IMHO, we don't have to worry about nuclear reactor safety at all. Operationally they are very safe (even Three Mile Island basically operated as it was supposed to during a meltdown). What is less clear is whether nuclear is economically feasible, and whether we have a viable solution for storing waste. Currently the solution is to store them on-site at the reactors themselves.

Granite (even without stressors) cracks. Concrete exposed to the heat from radioactive decay disintigrates. Stainless steel stresses from expansion and contraction and slowly weakens. It also is subject to (very slow) corosion.
The only practical method of disposal is passive storage where the waste is protected by layer upon later of different kinds of shielding. In practicality, the waste is placed in casks designed to hold in most of the radiation, these casks are then placed in a sort of glass-lined tomb which is burried deeply inside a granite cave inside of a mountain. When the tomb reaches capacity it is outfitted with monitoring gear and is filled with concrete and sealed. It is then "monitored" from outside the repository, if any problems are detected they will then take corrective action. Only problem is how do you do that? What happens if the detection equipment breaks down, how do you fix it?
I still have all these questions and I still wrestle with why would we make something that makes waste that is so dangerous? This is a real question that deserves a real answer and nobody seems to have a real answer.
Still, millions of tons of coal ash isn't harmless and there isn't enough oil to go around forever. The wind doesn't always blow and the sun doesn't always shine. We can't dam enough rivers and every year we get hungrier and hungrier for energy.
There are hundreds of ways to generate electricty (or more simply perhaps, to make energy). Every method has advantages and disadvantages. Most are hard to scale up to provide meaningful meagawatts.
Nuclear power is one of those things that scales up. It is in a sense "clean" -- simply because its waste per KWH is so damned low. We have learned how to reprocess, reduce, and recycle radioactive waste but we have not made it safe. The waste that remains is still very dangerous.
The Pebble Bed reactor seems to answer for the short-term at least for many of the safety issues inside of the nuclear power plant. It also reduces the waste generated (not in weight, but in reactivity). In some ways it is even easier to dispose of. Spent pebbles can be used to generate moderate heat allowing them to be used commercially in other applications long after they have been retired from generating electricty.
I said earlier that my views have mellowed a bit. Today I think that nuclear power probably has a place. I think that I would much rather see new plants with new, safer, and more efficient technologies be built than see forty year old plants with stresses components be recertified to operate many years beyond their original designers intention. If this is allowed to continue to happen the infrastructure will fail, people will die. We can not afford this. It is better to replace than patch and fix.

We can't do without even for a few moments but it comes at a very high price which will be paid eventually. Anyway, back to your point, I suspect most people wouldn't be willing to reduce their energy usage enough. Even if you got 2kw per day out of the sun, that's only 20 hours for one 100 watt bulb. If you have a computer, fridge, 6 lights, and TV on, you could be hitting near 1000 watts per hour (depending on efficiency of course).
Even me -- I realize how work intensive electricity is, and I try to make sure to make efficient use of it by minimizing my use -- still, it would be very hard to limit myself to 2kw per day, which is what I'd get with 10 hours of sun (good luck in Dec) and $1350 [altersystems.com]. Maybe there are better deals out there. I know for sure all those people firing up their generators sure won't survive on 2kw.

You no doubt know that the fallout from Chernobyl circled the globe? That it contaminated neighboring countries fairly heavily?
The problem with nuclear power plants is that they are very radioactive in their cores. There are elements with a wide range of half-lives and if anything happens to disperse them, you get high radiation for a short time, medium radiation for longer, and low radiation for eons.
If anything, I would say put them near centers of population That way, they are guaranteed the kind of scrutiny they deserve - lots of it. A population center with a lot to lose and no way to evacuate in short order in the event of an accident will work very hard to make the plants as safe as they can be.
Putting them away from population centers wastes a lot of energy in the transmission lines and also gives people a false sense of security where they won't press for answers or safety. The Enrico Fermi reactor that melted would have contaminated the whole northeast corridor. Too many don't realize that and think setting them 50 or 100 miles away makes them safe. It doesn't.

This made me think of another point. Any such plant like this creates about 2 units of heat for every unit of electricity.
While you can't get this up to 100% obviously, you can collocate various industries that need heat - such as ethanol plants*. Heck, run steam pipes to various buildings to provide heat. Ammonia refrigeration [nh3tech.org] using heat is a known technology, so it can even provide AC.
Even if you end up selling the heat ridiculously cheap prices - it's currently going up the evaporation cooling tower. Just like how a number of pollution products collected by scrubbers are actually valuable materials.
An ethanol plant getting cheap heat from a nuclear plant for it's processes would help lower the cost of the nuclear power(more money to pay off the building loan quicker) as well as lower the cost for the ethanol(cheaper to produce).
You're getting up to, at minimum, a large town to provide all the workers in the two(or more) plants, as well as all the support workers for them. People like doctors, teachers, waiters, accountants, police, etc...

"Contaminated" != killing everyone.
It certainly makes you safer than being located closer to it. Like any other contaminate, the contamination disperses more the further you are away from where it's released... With a nuclear fallout, 100 miles away could be the difference between "radioactive poisoning" and "3% increased risk of developing cancer".

And here's where I fit your caraciture: I do oppose raising energy rates and reducing consuption because it's anti-progressive, or as I prefer to say, regressive. Any extra burdens imposed on the cost of energy are going to disproportionately hurt the poor, and they've had it bad enough. Besides, it's totally unrealistic. Of course we should be doing more to insulate houses, and I strongly support government subsidies for doing that. But in a choice between reducing energy use and not reducing it while taking the risk of global climate catastrophe, Americans (maybe people in general) will choose the latter ten out of ten times. We can get mad about it or we can get realistic about it and provide them with the one clean source of power that we know how to develop on a large scale. Sucks that we'll probably have to bring in French engineers to do it right; we've really lost our technological lead in this industry!
Regarding the spent fuel, there is an obvious answer: Reprocessing. The most radioactive stuff that we bury now are the heavy metals which are actually fissile and could be used to produce more energy. The rest of the waste, if processed correctly, would be less radioactive in 30 years than the ore that was originally mined. So in the long run we'd be reducing the amount of radioactive stuff in the ground.

Secondly, reprocessing. The US's main focus for reprocessing is wrapped up in the Bush Administration's Global Nuclear Energy Partnership [energy.gov] (GNEP). This is a freaking scam, and the National Academy of Sciences [fas.org] backs me up. Basically, the types of reactors envisioned require materials science that just isn't there yet, requires funding that just isn't there yet, and requires an infrastructure that Just Isn't There Yet.
The solution is to turn Yucca Mountain [doe.gov] into a medium-term repository. Bury it, safely, for 100 to 200 years, let the exceptionally hot stuff decay away, and I'm pretty darned sure civilization will be able to find some use for the energy stored in there in 100 years. But until then, let the technology mature. The commercial industry (and, by extension, every person in the U.S. who pays for electricity) has been paying into the Yucca fund for too long not to see any return on that investment.
Oh, one more snarky comment. Please provide support via links for your assertions; it's not hard. I would like to see evidence that after 30 years, the spent fuel coming out of a burner like envisioned for GNEP is actually less radioactive than the original ore.

One potential solution is molten salt reactors, which do not use fuel elements but rather use molten uranium salts. Since there are no fuel elements, fuel from the reactor can be chemically treated without a lot of handling. It may even be possible to continuously process the fuel while it's still in the reactor (though this has never been done). Doing this could completely solve the problem of long-term nuclear waste. The only waste produced by such a reactor would be depleted uranium and fission products. Of course, the fission products would need to be safely stored for 300 years before they were safe, but that's a lot better than the trans-uranics that we have to deal with now.
Molten salt reactors also have advantages when it comes to fail safe design. Since they don't have fuel elements or control rods, there is nothing in the reactor core which can break or wear out and cause a melt down to occur. In the case of emergencies, the reactor can be drained into sub-critical containment vessels.
