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.
The other minor downside would be if the rocket blew up you would just have annihilated the entire planet...
Imagine what sort of a hideout that would be, for, say, an international terrorist or two ...

Man, the world is definitely getting to be more like "James Bond" than it is "Space, 1999".
Damnit.
Anyway, big deal about this nuclear repository problem, anyway. Once it's there, it's there, and all we gotta do is keep an eye on it.
Of course, getting it into that hole is going to be interesting. Imagine what a security nightmare *THAT* is going to be... I'd say a train carrying a bunch of nuclear, radioactive, material through, oh, say, 20 different states would be a pretty handy for any sort of weapon that would *burn* it easily.

What could be safer than disposing of unwanted bodies in the Nevada desert? Stick them in an enormous nuclear silo with 77 000 tons of stuff that'll kill you if you get near it! ;-)
Tales from behind the Lagom Curtain
one nuclear power plant makes 30,000lbs of waste per year. sending one pound of something into space costs $10,000.
now multiply those two numbers together to determine the cost of waste disposal using your plan. for one plant. for one year. then ask yourself who is going to pay for that
"He said increased unease about terrorist attacks makes it even more important that the nation's radioactive waste be consolidated."

How much money could you squeeze out of the US govt. if you live next door, and turn up with cancer or lose your hair or go impotent or whatever? Enough to make the remainder of your life and your kids' lives comfortable, I would assume.
And if you don't suffer any adverse effects, then what does it matter that there's nuclear waste next door?

Nuclear winters are caused by the dust kicked up by multiple warheads impacting and exploding on the earth's crust. A single rocket with waste blowing up in the atmosphere, critical mass or not, will not cause a nuclear winter.
What you will get is a nasty case of Chernobyl-style fallout, combined with a Mir-like dispersal of radioactive junk across a given hemisphere. Time to stock up on fallout shelters and iodine tablets...
If this waste is supposed to be generating temperatures of 400 degrees, why can't it be used to generate power? Not even anti-nuclear people could argue against it; its already nuclear waste.
Interesting to note is the removal of maps of the site from http://www.ymp.gov/reference/maps/index.htm
Didn't the Soviets classify maps too, to "minimize the risk of providing potentially sensitive information that could result in adverse impacts to National security"? (Quote from the site.)
Brave new world, indeed! Am I the only one who misses September 10th?
From the link:
Energy Department scientists contend those issues either have been resolved or can be dealt with as a final design for the facility goes through the licensing process.
I don't understand: if there still are issues which are not resolved, how can the decision to put the dump there be taken? What if the issues CANNOT be dealt with during the final phase? Does anyone believe that they will they be able to admit and back out?
I'm not surprised that the local politicians (and I suppose also the population) are NOT happy about it....
Also, in the post-9/11 world it'll be much harder to keep en eye on what's happening as "for security reasons" lots of stuff has been pulled from the Internet. For example, in France we have a recycling site at La Hague which used to give access to many webcams inside the installation (the new director's policy was "absolute transparency" to reassure citizens), but now they are offline....
One would assume that you could go an dump your heavy metals in one of the pacific trenches and let it get sucked back into the earth's core, right?
"Your superior intellect is no match for our puny weapons!"
This doesn't seem like it's the best solution here. I can think of two alternatives that aren't being used or investigated: 1) subduction zones. Put the waste deep into a subduction zone instead of a stable region like Yucca Mtn. Instead of hanging around basically forever, the waste will be pulled underneath the Earth's crust eventually. 2) Breeder reactors. Using breeder reactors would allow ALL of the Uranium isotopes to be burned in the production of energy, not just the U-235. That means that the ultimate waste product of the reactors would have a half-life of under 30 years instead of thousands of years. France deals with their nuclear waste like this already, and we should too.
If tits were wings it'd be flying around.
There was a Scientific American article about this alternative solution a few years back.
s ea bed.htm
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.

This might not appease the people in Nevada but it is many many times better than the haphazard method we use now of storing the waste at the nulcear sites.

What kills me is millions of taxpayer dollars have been wasted in non stop fights over this site. Yes, nobody wats it in their backyard and if I lived near the site (like within a few hundred miles) I'd probably think about moving. But in this world if its not a nuclear dump, its a real dump, a highway going through your house, high tension utility wires, etc. I'm currently in teh study area for a divided highway, with oone of the routes going straight through our house.

Much better idea:
Put the plutonium in a fast reactor and generate electricity while reducing the quantity of plutonium and creating shorter-lived daugter products. So, that's (1) reducing the amount of plutonium (2) getting electricity out of it (3) reducing the waste storage cost.
The problem is getting the screaming hedgemonkies in Greenpeace and Friends of the Earth to let you do it since it impinges on their superstitious beliefs.

Yucca Mountain is located at the NTS (Nevada Test Site), where the USA has performed most of its nuclear weapons testing. So it isn't exactly a pristine example of desert wilderness. The site also has the most of the needed infrastructure and security already there.
Mea navis aericumbens anguillis abundat
Well, although it seems you have some, er... unresolved issues with Nevada government as well as an unfortunate affinity for bold text, I will agree with you in principle. A mass driver to get this poisonous junk entirely off the planet seems like a reasonable proposition. Imagine mag-lev and an inclined railgun mass-driver able to accelerate a ton or more per shot to escape velocity. One problem is that it needs to face East (use the Earth's rotation rather than have to overcome it) and that makes most politicians based eastwards of wherever it's built nervous in case of a "partial" launch. A ton or more of highly radioactive nuclear waste landing anywhere can really ruin your next ten thousand years. And the US isn't a good place to site this - it's too far North - someplace near the Equator would be much better (that's why Ariane launches there). Maybe Colombia, Venezuela, Peru, even Panama or Puerto Rico? Their economies could sure use the massive cash infusion lasting decades until the job's done. And the system could be used to drive materials into orbit for space stations, Mars and beyond exploration (oops, different bureaucracy). But of course our vision impaired, cover-your-ass bureaucrats won't ever think of doing anything even remotely like this. They've spent $6 Billion on CYA for Yucca Mountain and they are determined to do it, whether or not it's the right answer or Nevada (or anyone else) objects to this. That said, it's a conservative choice - big hole in the ground under a stable desert mountain, way above the water table. Just hope they weld the doors shut when they leave, post warning signs, etc. Ten thousand years is a long, long time - about as long since people developed languages. Let's just hope global warming and geological changes don't turn Nevada into an inland sea in the interim, or something. Keeping it on-planet seems risky to me.
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...

I'm no expert (slight modesty), but there's a few problems with this idea:
a) sonic booms- concorde at Mach 2 gives big bangs for tens of miles; Mach 27+ sonic booms are going to reach hundreds or thousands of miles
b) failure modes- e.g. it doesn't quite reach escape velocity due to a coil failure and lands in the middle of Tokyo or something, causing not only dirty nuclear fallout that lasts 10's of thousands of years, but also straightforward meteorite style damage; or what if one of the coils shatters and hits one of the barrels at mach 20- not nice; really not nice.
c) ablation- the first 100m will probably lose atleast a couple of mach and quite a bit of the casing
d) solar orbits don't decay very much, for example the earth would have burnt up long ago
e) Orbital mechanics issues: to a reasonable approximation anything fired from the earth, still intersects the earths orbit twice per year, and takes a year to complete 1 orbit. You have to fire it quite fast to avoid this issue. It takes a LOT of speed to fire something from the earth and get it to impact the Sun; off-hand you'd need maybe Mach 32 or so

"Gravity is only a theory, not a fact!"Desert does not mean, nor is, wasteland.
A feeling of having made the same mistake before: Deja Foobar
When we started to do nuclear plants the idea was to build the plants we have today which basically "burn" Uranium. These plants usually take an enriched 3.5% U-235/ 96.5% U-238 mix (U-235 is what actually is Fissioned). After enough U-235 is spent to prevent efficient fuel usage, they remove the fuel and end up with a waste product which includes both U-235 and U-238 along with Plutonium-239 (Pu-239) isotopes and other radioactive isotopes.
What was supposed to happen is that this spent fuel would be reprocessed to extract the unused U-235, the Pu-239, and the other products. These would then be used in a fast neutron reactor which would actually burn not only the fuel itself but the waste products, producing as a result waste with a half-life of about 30 years (safe after 300 years and a lot less volume to store).
In the 1970's someone realized that the Plutonium-239 was also useful as bomb-making material. They decided that the risk of some of this being diverted to some third-world country which wanted a nuclear bomb was too high to take and so President Carter canceled the research project.
There is still a lot of debate over the real risks involved. From everything I've read I think the real story is twofold - first the Plutionium isn't really "weapons grade" when it is reprocessed in this manner, so the risks are over emphasized. And second, I think that the people running the power plants don't want to do this because it is cheaper to just run the uranium through their plants once.
Do government officials really have no other ideas except to dump waste on Native American holy sites? If these were Christian or Jewish or Muslim holy sites there would be no way in hell. But because they're Native American (and who really gives a damn about Native Americans, I mean, didn't they go extinct years ago?) we can just shit all over them.

It's 10 PM. Do you know if you're un-American?
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.
NPR is reporting this morning that the plan cannot go forward until Nevada has agreed to it. Their Congressional delegation is strongly opposing it, and Senate Majority Leader Tom Daschle (D-SD) is also against it. Until Nevada agrees to it, nothing will happen until Congress votes on it. And they won't vote for it while Daschle is in the driver's seat.
Nevada and Congress are aware of the issues involved in keeping this stuff in temporary locations, but there is a big NIMBY issue as well.
IMO, it can't hurt to be very, very, very sure this will be safely stored. A couple more years of study are not all that much when you consider this crap will still be radioactive 10,000 years from now.

Forget Yucca Mountain, what about the experiments going on down in the Black Mesa Research Facility!!!
Just think of the benefits:
The (Hopefully) Great Slashdot Blackout
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.
Folks,
When it comes to storing nuclear waste permanently, people are wrongly conjuring up images of thin-metal barrels of waste in liquid being dropped off.
WRONGO. Very likely, the radioactive waste will be mixed with molten glass and turned into glass balls, which are chemically extremely stable and have a tiny fraction of the radioactive output of spent fuel rods. These glass balls are then put into special large containers that are so strong even dropping them 30 meters wouldn't make anything close to a dent in the container. With the waste in barely radioactive form and these large containers, they could be dropped off anywhere undergground that has stable geology and never be an environmental problem to anyone.
I remember there was a bad joke going around early in the current Bush Administration about sending all the nuclear waste to Texas. That joke quickly ended when people read that DoE is actually looking at salt domes at now-dry oil fields in Texas as nuclear waste repositories, since salt absorbs radiation extremely well and these underground salt domes are geologically very stable.
For the first point, you're on the money. Even with a critical mass of waste on the top of the rocket, there would be nowhere near critical density, so no boom. However, on the second point, you're off the money. With a properly designed drop vessel, if the payload had to leave the booster for any reason, it'd fall to earth without burning up (think reentry of human astronauts; the same type of vessel would protect against burnup of the waste payload). There are three problems with jetting nuclear waste into the Sun instead of burying it locally. They are:
1.) Money
2.) Money
3.) Money
It's far too expensive to put stuff into orbit to consider lifting off heavy metals instead of putting them in a deep hole.
Virg
Why?
First, it's certainly not cheap to launch the stuff into the sun (which is harder than you might think)
Secondly... rocketry is dangerous. What happens when the thing explodes in the upper atmosphere? Radioactive waste aerosolized and spread around the globe? Not a really good idea (and probably a primary reason for not doing it)

As a Utah resident, I happen to be well aware of the industry's backup plan: They want to simply put the containers in a big parking lot owned by an Indian tribe. They would keep the containers there until Yucca Mountain opened. The nuclear energy industry has promised "a lot of money" (nobody knows how much) to this tribe, but the leadership of the tribe has recently shifted. Perhaps this had something to do with the decision.
Anyhow, if anybody decided to drop an airplane on their open-air parking lot then bye-bye Salt Lake City. If the winds were just right Denever might go too.

The DOE was ordered to study a list of sites, and to build at the site on the list which was safest. Not told to determine if any of the sites were adequate, but to choose the best and go forward.
The list was: Yucca Mountain.
That's it. No second candidate. Along the way, the general press in Nevada took to labeling the laws "Screw Nevada I" and "Screw Nevada II". Senator Johnston of Louisiana had the votes to push them through. When a professor at UNLV got a little to noisy about the problems with the site, UNLV received a supercomputer to shut him up (really. They never quite figured out what to do with it, but that's another story.) And then the building where DOE housed the project studing earthquake safety took over a million dollars in damage from--you guessed it!--a routine (for the region) earthquake.
I'm a Nevadan, and my permanent home is in Las Vegas, about 100 miles from this site. I have absolutely no qualms about a nuclear storage facility that close to my home run by scientists. I'm terrified of what's being done here, though.
One more time: There was not a study to see whetheror not the site was safe. Therewas a study to prove that this site was safer than, uhh, nothing.
I'd feel a lot betterif this was turned over to the state (heavens, no, not the local governement. Look at the last couple of mayors of LV: Oscar Goodman, who became wealthy denying there was a mob while representing it; Jan Laverty Jones, commercial girl for the Fletcher Jones car dealerships who showed up at times in a chicken suit or in a black velvet jumpsuit as her own evil twin . . .

Because getting something into the center of a gravity well is deceptively difficult. Any little mistake and, instead of plunging into the sun, you whiz on by in a highly eccentric or hyperbolic orbit. If it were easy to get something to fall into the sun, there'd be a lot less comets in the solar system than there are now.
Jeez, where do you people get your math? Let's address:
;.)) would cause a fairly short, backward-curving (relative to Earth) drop into the Sun lasting less than three months. And, barring escape velocity (which is extremely high) once it's out of Earth's orbit the speed at which it's moving is relatively unimportant, unless the Greenpeace detachments for Venus or Mercury are worried about a package striking those planets on the way in.
> a) sonic booms- concorde at Mach 2 gives big bangs for tens of miles; Mach 27+ sonic booms are going to reach hundreds or thousands of miles
Sonic booms happen when you cross the sound barrier (that's once, at Mach 1), and they don't get louder under harder acceleration.
> b) failure modes- e.g. it doesn't quite reach escape velocity due to a coil failure and lands in the middle of Tokyo or something,
A valid concern, but it could be handled through several possibilities. First, the launch package could be designed to allow for controlled abortion of launch in the case of launcher failure, just as astronauts can "eject" from a failed rocket on launch. Second, the package can be designed for reentry (and safe landing, like a manned capsule) in the case of low-apex launch failure.
> c) ablation- the first 100m will probably lose atleast a couple of mach and quite a bit of the casing
Again, this problem could be designed out.
> d) solar orbits don't decay very much, for example the earth would have burnt up long ago
Huh? Didn't pay much attention in physics class, did you? Orbital mechanics is orbital mechanics, and there's nothing special about the Sun's gravity well. The reason the Earth hasn't burned up is that we're in a stable solar orbit. Stuff falls into the Sun all the time.

Again I'm baffled by your physics. The first sentence is simply incorrect. To wit, let's discuss the best launch vector for such a device. The original poster suggested an eastward launch, with which I can agree. However, this launch could be timed so that when the object exited our gravity well it's moving back along our orbital path (that is, back the way the Earth came from), minus some number of degrees into the ecliptic. This would put it on a slowly arcing orbit toward the Sun that would bring it nowhere near the Earth's orbit ever again, and if properly calculated (which may be tough considering what happened to the Mars probes
All that said, it's still very likely to be prohibitively expensive to lift these containers out of Earth's gravity. Rail guns are useful to accelerate objects to insane speeds, but they're much less efficient in terms of necessary input energy than other forms like rocket boosters, so there's still the BIG problem of cost.
Virg
Fast breeders produce more plutonium than they burn. You load in a lot of U-238 along with enough U-235 and Pu-239 to maintain criticality and during the ensuing core life that U-238 breeds into Pu-239/240/241 etc... Plus if you have loaded other fission wastes in there the neutron flux will "burn" them away. Yes, you are left with shorter half-life highly energetic stuff. But it's no worse than what comes out of a core now. And you are reducing the volume and the time it's dangerous by several orders of magnitude. The storage time is on the order of 50 - 100 years.
This technology was out worked completely over thirty years ago. The ONLY reason we aren't doing this is political.
> Why isn't the government doing this instead of burying it underground?
Because they can't afford to. Lifting stuff out of Earth's gravity well is alarmingly expensive (more than ten time as expensive as just getting it into Earth orbit). To say, as you did, that it's "probably a little more expensive" is such an understatement that it's almost funny. If we (the U.S. alone) were to take this practice up as a nation, assuming that everyone paid the same part of the resulting bill and assuming that by some means the government could cover 90% of the tab, the average power bill for a U.S. citizen would still be around $8,000.00 per month. That's per MONTH. Could you afford $10,000.00 annually for your electricity?

You would have about a snowballs chance in hell of raising the temp of the ocean a billionth of a degree. Just think how big the ocean and the earth really is. Now think about how much heat just the Hawaiian hotspot put's into the water.....80,000 tons of more than 10 year old waste (after ten years the heat output is about 1/10000 of the heat when first discharged from the core) is not going to put out enough heat to do anything to the ocean by comparison.
The French underground site for radioactive waste disposal offers tours of their two disposal sites and one R&D facility. Their deep disposal R&D site is in rock that hasn't done anything exciting for the last 150 million years.
It isn't just a few dissenters, and their voices began to be raised early in the 20 year time span...
How few people do you sacrifice for the good of the many? Programmers are certainly a minority in the world, and we scream bloody murder every time a patent or trademark intrudes on our work.
Using your logic, we should just shut up, since a patent may well "benefit" more people than will the "freedom to code" of a "few" disgruntled programmers!
If anything, I hope the non-Indian people of Nevada learn something from this: That stealing rights from anyone (the Shoshone, in this case) allows government to steal rights from us all. Sadly, most people only focus on "their" needs and "their" rights, failing to see that we are all in this together.

True. But you do if you want to use existing core designs and save money.
Is it just me, or is this a monumentally stupid idea?
Under capitalism man exploits man. Under communism it's the other way around.
WIPP stands for Waste Isolation Pilot Plant.
It's designed to allow the DoD and DoE to learn more about disposing of transuranic wastes from US atomic weapons programs, and from military reactor cores, not from commercial power plant waste. It's only a small fraction of the size of the Yucca Mountain facility.
>Sonic booms occur at mach 1
Nope, sonic booms only occur ABOVE mach1. They occur throughout the transonic flight regime.
As to intersecting the sun- this might be best achieved by firing the gun roughly horizontally, 35 degrees east north east at about mid-day so that it leaves the earth at exactly the earths orbital speed plus earth escape velocity; and gains the earths rotation speed.

"Gravity is only a theory, not a fact!"I have always been astounded at picking 10,000 years as a number. This is longer than written human history. If you think about the technological changes between 8000 B.C. and now, and think of where technology is likely to be even as soon as 3000 A.D. (much less 12000 A.D.) even 1,000 years ought to be plenty.
Of course, you have lots and lots of people who would rather that the waste sit in the temporary storage facilities near major metropolitan areas for the next 10,000 years. That looks VERY good to them. That is the only alternative to Yucca Mountain that I can see, and it is not pretty.
Practically every posting here, every statement made by an interest group or a politician, make it perfectly clear that the very last thing that to be considered to decide where this waste ends up will be the most practical scientific solution currently available. Nobody is saying that there is a better solution than Yucca Mountain, just that Yucca Mountain isn't "good enough." I think the issue must be Yucca Mountain vs. the status quo. The naysayers will just keep lifting their bar otherwise. (100,000 or 1,000,000 or 1,000,000,000,000,000 years, whatever)
Actually, they WOULD be farther ahead. It can't be any worse than listening to people who think "NUCULAR? I don't want no nucular plants in my backyard. It might blow up and destroy the Earth! We've got to stop all this nucular technology because I'm afeard of radiation making my turnips too large to fit into my icebox." All of the people on this thread who didn't post as an anonymous coward don't seem to have that knee-jerk fear that blocks some people from even considering possible alternatives like breeder reactor fuel recycling.
If tits were wings it'd be flying around.
A few corrections... (ignoring the many spelling corrections - are you 16 years old or something?)
The original plan put forward by the AEC was for several nuclear chemical processing plants to reprocess spent reactor fuel into mixed oxide (MOX) fuel to be reburned in the (couple of hundred) nuclear power stations. The waste products would end up passing through several power core cycles before finally being removed for burial. At that point they would be hazardous for about fifty (50) years. This process actually makes more fissionable material than it burns.
This technology exists right now. It is not new or unfinished. But because of political concerns rather than scientific/engineering ones, it has been stalled for at leat 25 years. So we are still using the "once through" cycle method.
And the 400F figure is an upper analysis boundary for safety testing. The actual number will be far less, probably less than 150F. Who cares if some rock 1000 feet underground gets heated from 85F to 150F ? It just will not matter.
First things first. On rereading my response, I was crankier than I intended to be, so my apologies for my tone.
On the points, further thoughts:
> a) sonic booms occur above mach 1 not at mach 1.
Agreed, but there are two things to consider. Firstly, jets make a lot of noise, but something thrown from a rail (or coil) gun doesn't, until it uses afterlaunch engines. Secondly, since this object is to be moving upward and two miles off the ground by the time it begins its own acceleration, I didn't consider the sonic boom to be an issue.
> b)&c) Making a mach 27 object survive at all is not easy.
Holy crap, I'd hate to try to design that object. I didn't realistically consider that this object would be thrown into orbit by the launcher alone, a' la Jules Verne's moon bullet. My thought was a booster engine thrown up into the air by the launcher, which ignites and completes the exit burn. On review, I never mentioned that in my reply, so reread with that in mind and it makes more sense.

A simple misunderstanding here. I'm focused on the problem, so I didn't consider a decaying orbit so much as a death shot. I considered "impact" (insofar as anything can impact a star) to be the goal and thus, the target. If the arc is calculated correctly, the object passes into the Sun's corona, which I'm sure you will agree will alter its orbital mechanics to a great degree. Hence my comment on stable orbits (again, sorry for the tone) which does not apply to paths which are so elliptical as to pass through the orbited body.
> Oh yeah, you mention rail guns.
Only because to original poster did, but considering the above comment about points B and C (that I was assuming an assisted rocket, not a ballistic object) the rail gun is not a completely undoable approach, considering power needs.

Tell me about it. Check my profile. I reply to 15 FUD posts here, and before I hit submit on the last one, there are thirty new FUD replies.
Exhausting.
Do these people have medical doctors they trust? Do they trust the engineers who designed their cars? Airplanes? Trains? Do they trust anyone with any kind of engineering? How about if someone came to them and said Linux sucks because (insert FUD here)? Especially if that person was not a programmer or software engineer??
It comes down to this, ignorance breeds fear and distrust.
Plus some people want to make a name for themselves by scaring other more ignorant people.
I'm not sure why people think a special reactor is necessary in order to burn up the plutonium in a power plant. It fissions perfectly well in an ordinary power reactor - by the time a fuel rod is too laden with neutron-absorbing fission products to sustain a chain reaction any more, about 40% (IIRC) of its power output is from the plutonium that was bred in the rod. By that time, a significant percentage of the plutonium has been transmuted to Pu240 and Pu242, which makes it somewhere between very difficult and impossible to make a bomb out of it.
(If power plant plutonium could easily be made into bombs, wouldn't India have done so, rather than going to the trouble and expense of building a special-purpose breeder? Wouldn't Pakistan have done so, rather than building an isotope separation plant to make U235 bombs?)
It may require something special if you want to use pure plutonium in a fuel rod, but mixed uranium and plutonium is producing power in every nuclear power plant on the planet, right now.
Current thought on the other transuranics is, you put them in a new fuel rod, and they'll alternately absorb neutrons and decay, until they hit a fissionable isotope of something, at which time they will cease to be part of the "transuranic" problem, and become part of the "fission products" problem. (And generate energy to boot.)
If you only bury fission products, forget the "tens of thousands of years" hype. In about 500 years, there's less radioactivity in the waste than there was in the ore the uranium came from.
The inescapable fact is that there is no choice about implementing disposal of nuclear waste. We already have enough of it that not developing a disposal site is not an option.
The anti-nuke types do not want any disposal of nuclear waste to be permitted. It doesn't matter how good the site is. They want the waste to remain right here on the surface, where it can be used as an "issue".
I think the anti-nuclear crowd often conveniently forget that Chernobyl was a disaster waiting to happen because there was no containment structure and also no really decent backups for the radiation moderating system.
Indeed, Three Mile Island was proof that the American safety measures for nuclear powerplants WORKED. The containment structure at TMI did succeed to keeping the radioactive release to a very low level indeed.
Anyway, the nuclear waste will be processed into a form that has a tiny fraction of the original before being stored away. It'll probably have less radiation that many natural rock types anyway.
Keep in mind that these numbers are wildly rounded off, but it comes from the cost of lifting a pound of material into space, out of the Earth's gravity well, which is around $10,000 per pound. It's safe to assume that you can cut that by a third, because the only things we've put out of Earth's orbit were devices we didn't want damaged (or people), so you can cut corners if you're not concerned about failure after escape. Then, multiply that by the number of tons of radioactive waste that U.S. generation plants create (spent fuel and other "hot" items like tools, machinery and containers) and divide the answer by the number of people in the U.S. Chop off 90% for my example and the result falls around $8,000.
Overly simple, yes, but it does serve to prove my point.

> it's still impossible the delta-v for this is much too large...
I'm not sure I get you. If a rocket booster can lift off from a standing start on the Earth's surface, why is it impossible to start it moving with a rail/coil gun and then start the burn when it leaves the launcher? Since a railgun can accelerate the object at any speed (modifying the current lets you pick the potential difference and thus the delta-a), it's not required to chuck it into the sky at Mach 20+. The use of the launcher is to give the rocket a kickstart so it can carry less fuel (thus less weight) and still get out of Earth's G-well. As an example, take something very dangerous that we did as kids for illustration. We used to build and fly model rockets. We discovered that if someone stood on the flat and held the rocket in hand, he could throw it upward off the ground. Then the "launcher" would run like Hell and "mission control" would hit the starter. Barring a bad throw or entangling (or igniting) your launcher, your rocket would climb noticeably higher because it was already moving upward when the engine fired.
I'm still sure the cost is prohibitive, but I'm having trouble seeing why the physics would interfere.

I can only reply to you with what I am familiar with, I work at San Onofre, and I am familiar with the seismic engineering in place here.
It's overly simplistic to say horzontal movement and Richter scale number are the only things designed against.
A properly qualified seismic design is against the g forces (horizontal and vertical)at the location of the structure.
What this means is, you have to do very thorough geological studies in the region of the structure in order to understand how it will transmit energy to where you have your design. I.e., where are the nearest active faults, what is the largest rupture that could be generated from that fault, what subsurface structures are between your building and the fault. Once you have all this data (and some other stuff too) you can calculate within a specified degree of statistical certainty what the maximum g-force at your structure location will be for specified amount of time, say 100,000 years. You can then use this to generate design criteria. With the proper amount of engineering conservatism, you can design a structure to withstand any significant earthquake to be expected in the lifetime of humanity. It's all a matter of cost. You can design in the strength needed to withstand the g-forces from a 8.0M earthquake anywhere, but why waste the money to do that if nothing more than a 6.5M earthquake can be expected to occur in the next 250,000 years?
I agree that strorage is not a permanent solution. It's the next best thing, put this stuff in a centrally guarded location. Easily retreivable for later use (or a permanent solution). It's definitely safer than leaving it at 70 odd separate storage locations across the U.S.
One last comment on the bridges here in SoCal, It was the support pillar connections to the underside of the bridges that was the weak spot. And the secondary (but almost as bad) problem was the structural strength of the pillars' concrete. Once the existing pillars were wrapped in high tensile strength steel cylinders, and the connections to the underside of the bridges were beefed up, that basically took care of the problem.
40 inch drop puncture test -- That's the MINIMUM distance a container would drop if it fell off a STATIONARY train. Most tracks are placed on top of embankments which at least double that. Considering that within 20 miles of my home there are 3 (that I know of) railroad bridges where the drop to the SHARP rocks below is at least 50 feet, plus the fact that the train would likely be traveling in excess of 50mph, a 40 inch drop is equivalent to kicking the tires of your car. Unless there is a serious defect, this proves nothing relevant to real world performance.
That pretty much covers the 30 foot drop to a flat surface standard as well
1475F for 30 minutes -- sounds impressive, until you consider that estimated temperatures inside the world trade center exceded 1600F (which, btw, is what caused them to actually come down. With less heat the upper stories would merely have been gutted by fire, with little or no actual structural damage.) What if it's subjected to heat before it's dropped?
50 foot immersion for 8 hours -- how exactly does one recover one of these 25-120 ton casks from under 50 feet of water? How long would it take to get the necessary equipment and trained crews to a remote location, for the divers to prepare their dive plans, etc?
The actual tests listed are much more impressive (and realistic), but no statistics about repeatability are listed. So what if a container can withstand one of these tests, can 30 containers in a row survive? (Note that 30 tests is the minimum number for true statistical significance.)
Another issue is terrorism. This is briefly touched upon in the article you linked, but important details are missing, such as the size of the explosive used. Regarding hijack, 25-40 tons is not unmanagable. A licensed heavy equipment operator can easily rent (or steal) the necessary equipment. In my area heavy equipment yards tend to be located near railroad tracks, probably to facilitate shipping/recieving of equipment, but price/sq.ft is likely also a factor. Security tends to be pretty lax at these yards, generally consisting of a padlocked chainlink fence.
It may come as a surprise to you to find that the people who designed our nuclear infrastructure are neither stupid nor suicidal.
It may come as a surprise to you to find out how hampered these designers are by politics, beaurocratic red-tape, and "financial concerns". That's true of any design project, and quite visible in the design standards listed here.
It may also come as a surprise to you that the NRC is almost completely controlled by companies it's supposed to be regulating.
