Yucca Mountain, Open For Business
John Galt writes: "It seems the Feds have finally decided that Nevada will host the government's nuclear waste repository." The Yucca Mountain project has been in the works for a while. Here is a cutaway diagram.
There was a Scientific American article about this alternative solution a few years back.

Vol. 276, Jan. 98, pp. 60-65, Burial of Radioactive Waste Under the Seabed.
Holes could be drilled hundreds of meters below the seafloor in geologically inactive areas. Canisters spaced around 10 meters appart could be lined up around the bottom. Removal (in case something goes wrong) would not be a problem with a rentry cone at the top for a future drill.
It turns out the mud under the seabed has a consistancy of peanut butter, ideal for slowing the spread of any radioactive waste.
"Around 1,000 years later the metal seathing would corrode, leaving the nuclear waste expodes to the muds. In 24,000 years (the radiocative half-life of plutonium 239), plutonium and other transuranic elements would migrate outward les than a meter."
Unfortunatly this soulution is sometimes grouped with "ocean dumping" an therefore prohibited by international law.

There was a design competition about this - my favorite is the Landscape of Thorns.
There's always a lot of talk of shooting nuclear waste into the sun and/or into space as an alternative to underground storage. Over the past 30 years, 77,000,000 lbs (35,000,000 kg) of nuclear waste (from reactors) has been created. Rockets commonly used today for space launches (Atlas, Delta, Titan, etc) can put about 4,000 - 5000 lbs into an earth escape trajectory.
Give these numbers, that would require about 15,400 launches to get the nuclear waste off the earth and out of earth orbit. The rockets that we would most likely use for this have a failure rate of about %5. This would make about 800 failures. 800 failures in which 5000 lbs of nuclear waste could potentially be spread into the atmosphere and the air.
I know these numbers are just numbers, and statistics are just statistics, but I think it shows that the risks for launching nuclear waste into space are unacceptable.
Yes, read that again. The pedestal for the statue of Roger Williams (Rotunda/Senate Chamber Hallway, U.S. Capitol) gives off about 30 microrem per hour... more than the proposed standards for radiation at the perimeter of Yucca Mountain. Just to put it in perspective.

I've been closely following the Yucca Mountain investigations since the mid-1990s; my garage has hundreds of thousands (really!) of pages generated by various parties involved in this effort. I doubt DOE will continue to be so free with its literature, in light of "security cenrcenrs" raised by September 11th.
But I digress.
In a nutshell: "Approval" of the storage facility has been a foregone conclusion since the studies first began. Yucca Mountain was the only site studied, and any "problems" discovered have been ignored or glossed over.
The real problem is a lack of planning -- it isn't just the "Internet generation" who can't think ahead. Back when we began building nuclear power plants, no one thought about what we would do with the waste -- and so it now sits in over a hundred locations around the U.S., in hardened canisters sitting next to power plants. Because no one looked ahead fifty years ago, we now have a crisis on our hands, and little chance to make a rational decision.
The problem at hand: Nuclear waste needs to be stored somewhere, and Yucca Mountain is the only site selected for study. There may not be a rational, safe solution to the problem of nuclear waste -- and so Nevada's residents may take it in the shorts because of short-sighted and selfish politicians and
I say "may" because Nevadans are unlikely to lie down and "accept the inevitable." They're a feisty bunch, especially the ones who don't live in Reno or Lost Wages -- er, Las Vegas. The Ages Brush Rebellion is gaining strength again in the American West; confrontations between federal officials and local residents continue to rise.
You don't think this issue affects you? If you really think freedom is important, you might want to consider that Nevadans will be hosting nuclear waste that they did not create, as dictated by the federal government on behalf of big, stupid corporations. (Note: I like lots of businesses, even big ones -- but I have great disdain for stupid companies and people who impose their mistakes on others.)
For a somewhat different perspective on the issue, consider this article about the people who actually own Yucca Mountain:
Stealing Nevada
That article (which I am currently updating) has been published all over the world (search Google for it) in print and online. It won't make much difference, of course, because most people only care about right and wrong when it affects them directly. It's too bad, really; what the federal government is doing today with national IDs, intelletual property, and waste dumps is the direct result of letting them push other people around.
Good luck to those in Nevada, Shoshone, Paiute, and other-American alike. You need it...
All about me
In any engineering discipline, there are all sorts of problems which need to be solved. Just because those problems exist doesn't mean they can't be solved. In fact, you usually do something called 'risk reduction', which means you sit around and think of solutions to a problem, and backups to those solutions.
Many public problems with the government (and the private sector, too) are the results of a 'common sense' approach to engineering projects. "I know how long it takes to drive to the grocery store, therefore the government should know, to the dollar, how much it would cost to build the most technologically advanced strike fighter in the world ten years before they do it."
Jack Valenti and the MPAA are to technology as the Boston strangler is to the woman home alone
There was a great article in Analog a year or two ago in which the author debated how exactly one would label a place that will be highly toxic for tens of thousands of years. You can't use the same symbols or words we take for granted to mean danger; who knows what people will use to denote that in the distant future?
Ideas bandied about included making the surface from dark stone tiles so it would be too hot to approach or making some huge symbol on the ground to warn people away.
The main problem, though, was whether anything you do to warn people off would actually end up attracting them. Imagine making a huge warning that future generations or visiting aliens think is just something cool like the lines at Nazca.
A. Subduction zones move material two directions. Soft material on top of the plate is scraped up and piled into mountains. Only the hard rock plate goes down. So anything we drop will go up, not down. You might as well put it in a mountain of your choice rather than a random mountain of the future.
B. It takes for ever for anything to happen anyway. Geologically, Yucca is just as good as subduction. By the time anything happens, it will only have moved a few feet anyway.
There is nothing so silly as other peoples traditions, and nothing so sacred as our own.
