Martin Hellman sends in a pointer to his essay that uses analogies from cryptography and the sport of soaring in an attempt to draw people in to thinking about the risks of nuclear weapons. Quoting: "... I did a preliminary risk analysis which indicates that relying on nuclear weapons for our security is thousands of times more dangerous than having a nuclear power plant built next to your home." Hellman is best known as co-inventor (with Diffie and Merkle) of public key cryptography, and has worked for over twenty-five years to reduce the threat posed by nuclear weapons. He is also a glider pilot with over 2,600 logged hours. Hellman adds, "Readers needing a break can go to some photos of the Sierra Nevada mountains taken from my glider."

That's because of tremendous ignorance about even the basics of radiation, such as the longer the half life, the lower the radioactivity. And that while high levels of radiation are of course very bad, something with a half life of ten thousand years isn't necessarily more poisonous than something that isn't radioactive at all. Oh and of course there's the general fear-mongering of all things radioactive since the dawn of the atomic age, perpetuated by Hollywood myths where even in the distant future any nuclear reactor is a single leaky coolant pipe away from nuclear detonation.
Whereas inhaling the byproducts of coal power plants has been an American tradition for over a century. So nobody thinks about how bad it really is.

I think that's overstating it a bit. The rational reasons for not reprocessing fuel revolve around the following issues:
1. Transporting used fuel to the reprocessing center and back.
2. Production and separation of enormous quantities of Plutonium, which needs to be carefully guarded due to proliferation and terrorism risks.
3. Some hazards in the reprocessing itself. There have been several serious accidents in reprocessing plants, for example:

http://en.wikipedia.org/wiki/Tokaimura_nuclear_accident [wikipedia.org]

4. Reprocessing only really starts to make good economic sense if you bring fast breeder reactors online, and those have safety issues of their own.
Something like the IFR (http://en.wikipedia.org/wiki/Integral_Fast_Reactor) might substantially reduce these risks, but until an advanced breeder reactor is actually built and operated for a significant period, it's hard to say how safe they really are, and whether they'll make economic sense.

While you are correct that Chernobyl was a bad design and an ill-conceived experiment started the disaster, do you recall what caused Three Mile Island or what the consequences might have been had the hydrogen bubble ignited?
Do you recall that TMI happened BEFORE Chernobyl, and sparked a quite thorough redesign of reactors to make them safer, and GenIV reactors, if we ever get around to building them, would be safer yet?
And the bigger problem is the cost and various issues with properly sequestering the waste. Using nuclear power is basically like borrowing to run the country - we get the immediate benefit and our children have to pay the price.
First, the stuff is safer than coal - a lot of the pollution from coal actually ends up in the environment. Besides that, I(and many other nuclear proponents) figure we'll be going after that high level waste in less than a hundred years to use it as fuel again. Other options include breeder reactors and reprocessing using modern methods to reduce the amount of waste, and the lifespan of the waste, substantially.
Any idea how much it will cost to pay just for the guards to monitor a waste site for 100,000 years or so? I don't think that is factored into the cost of electricity from a nuclear plant, is it?
How long until the Mercury released by Coal plants exits out of the environment? How long until the CO2 is sequestered again?
And yes - it is factored in. The federal government told the nuclear power plant operators: You WILL pay us $X per megawatt/hour produced. We WILL dispose of the waste. There's lawsuits going on about that one.

Um... it DID ignite. Several times. Ignition of hydrogen in the reactor core only complicated a difficult situation. However, the reactor operated more or less as intended in that situation and the risk to the surrounding area was minimal. Certainly not anywhere near Chernobyl levels. (Chernobyl ran into a lack of shielding against a boiler explosion. So all those materials were spread around surrounding areas rather than being contained by three feet of concrete.)
That's a terrible analogy. Nuclear power is just fine. Most of the hot stuff is gone within days to months. That's why reactors can be serviced and/or dismantled within a few months to a few years of being shut down. If anything, we're leaving our kids a nasty power crisis and dirty air because we refuse to build more nuclear plants!
I am being completely serious here. Any materials that last that long are more than safe enough. Heck, anything with a nuclear lifetime that long is safer than the Potassium stored in your body*.
Think about it. Radiation is a process whereby mass is converted into energetic particles. Thus the mass itself is the fuel for the radioactivity. The more radiation produced, the faster the mass is converted into that radiation. In result, the mass will burn itself out in a short period of time. Materials with 10,000 year lifespans convert their mass to radiation so slowly that you can count each particle as it is produced. Compared to cosmic radiation, that's a zero risk.
Furthermore, there are different types of radiation. A great deal of radiation (e.g. alpha and beta) can't even penetrate the dead layer of cells on our skin!
In effect, the situation with nuclear radiation has been overblown. Read up on radioactivity if you want to understand the true dangers of working with the material. Once you understand things better, you may start demanding that your local coal plant be replaced with a nuclear plant! (Did you know that coal plants disperse more radioactive material into the environment than any other power-producing technology?)

Let's be clear for a moment: Litvinenko was poisoned. He didn't accidentally ingest 10 micrograms of Polonium 210 any more than you or I have accidentally ingested 5 mg of Pu-238. With a half-life of about 1/3yr, a temperature that easily exceeds 500C, and a heavy weight that prevents it from becoming airborne, Polonium poses little risk outside the laboratory or industrial environments where it is used. In addition, Polonium is a highly stable heavy metal that is unlikely to chemically bond to common materials and/or make it into the water or food supply like the more concerning Su-90 or I-131.
The greatest concern with Polonium-210 is that tobacco fertilizers contain the material [nytimes.com], probably from natural Uranium decay in the soil. The tobacco plant absorbs the chemical and thus it gets into cigarettes. The quantities are miniscule, even by Polonium-210 standards (partially owing to the short half-life), but enough to eventually lead to lung cancer.
Let's count up the deaths, shall we?
Three Mile Island [wikipedia.org]: 0 deaths
Chernobyl [unscear.org]: 47 deaths (there were also 4,000 cases of Thyroid cancer that were successfully treated)
London Great Smog [wikipedia.org]: 12,000 deaths
That last one was caused by burning coal. 12,000 deaths from a disaster caused by burning coal. Versus a maximum impact from nuclear power of ~4,050 people. (Only a small handful of who directly lost their lives.) And that's DESPITE the USSR building a sub-standard facility, DESPITE the USSR requiring untrained personal to safety test the facility, DESPITE the lousy and late evacuation job, and DESPITE the massive release of radioactive materials.
If that's not sinking in, read it again. Coal is MASSIVELY more dangerous than nuclear power plants. Period, end of story. If you have your brain even half-way engaged, you should be demanding that every one of our coal plants be ripped out.
(The 125,000 death figure, BTW, is a myth [magma.ca].)

Rather, waste management [from reprocessing] is made very much easier. The decree that Yucca Mountain must isolate the waste for more than 10,000 years is due primarily to the presence of long-lived transuranic elements. Appropriate reprocessing will allow those troublemakers to be consumed in fast reactors, leaving only the real waste--the fission products--to be disposed of, and their radioactive toxicity fall below that of the original uranium ore after less than 500 years. Effective waste management becomes a slam dunk.

Both would require significant reprocessing to be made into weapons. If you must do it, it's much easier to reprocess Uranium. At least then you'll be ready to build your bomb. With Plutonium, you're not even half-way there.
