http://www.uic.com.au/nip51.htmAbout twenty million packages of all sizes containing radioactive materials are routinely transported worldwide annually on public roads, railways and ships.
These use robust and secure containers. At sea, they are generally carried in purpose-built ships.
Since 1971 there have been more than 20 000 shipments of spent fuel and high-level wastes (over 50 000 tonnes) over more than 30 million kilometres.
There has never been any accident in which a container with highly radioactive material has been breached, or has leaked.
Just to be clear, I want to restate that I agree - mostly for economic reasons. Ie.chroot said:I have to agree that sending our nuclear waste into our space is not a very sensible option.
I also read that the US has 52,000 tons in storage now that would also need to be dealt with.My research indicates that there are 441 nuclear reactors in operation worldwide, each of which produces about 25-30 tons of high-level waste per year. While this waste is relatively small -- only 3 cubic meters per year -- it is very heavy.
Technically possible, but yes - cost prohibitive. Now if that "Orion" thing ever happens... but I won't go off speculating on when/if that would be possible.The space shuttle orbiter weighs about 100 tons at launch (and it only goes to LEO), and the Saturn V's best payload estimate was only about 52 tons to the moon. This means you'd have to launch the equivalent of a space-shuttle-sized rocket vehicles every other day just to keep up with the job, if not more.
There is a lot of crackpottery floating around about transmutation at the moment, which is why I'm heasitant to speculate about it - but I'm an optomist and I'd never bet against technology. In 50 years, it may well be a good option.I'd still put my money on transmutation technology. At some point it will become economical, and research in it will accelerate.
99.9%? 1 in a thousand? That's it? Heck, why are we arguing - we're already there?cyrusabdollahi said:As long as you can tell me with 99.9% certainty that that rocket ant going to come down into a city or a water source because of some sort of a fluke in the deisgn, (sorta like NASA mixing up units and crashing on mars), or that they won't make stupid moves because of time constraints and pressures, (sorta like NASA challenger) when dealing with dangerous materials.
Agreed - so then we digress. Back to the point about doing for the next 50 years what we've done for the past 50: Nothing. What's wrong with it?As you said, one launch every other day, would be a daunting strain on NASA to keep up. Not to mention, all those rockets are one time uses. And this is something that we will have to pay for, forever.
It would need to be able take a very heavy cargo outside Earth orbit. That in and of itself will take quite a bit as Chroot pointed out. Once to that point though I don't think it would take much more. Just some manuevering thrusters. Set it on a path towards the sun, probably spiralling inward to take advantage of what would more or less be a natural path. That is natural as in it will continue of it's own accord without need for any fuel. It's definitely not a very economic option at this point in time but I really don't think it would take much more to get it on it's way to the sun. Russ or Chroot would likely be more qualified to answer.cyrusabdollahi said:Another point. Don't those rockets send stuff into Earth orbit. Wouldn't you need a MUCH bigger rocket to send something to the sun? The satern V was used to go to the moon. I would think something at least as big would be needed for the sun, which is further, unless its easier to go to the sun.
There are, however, lower orbits that are stable enough to park trash for thousands of years.
This technique has been patented in the U.S., Canada and Australia. The process is described in detail here.Subductive waste disposal method is the state-of-the-art in nuclear waste disposal technology. It is the single viable means of disposing radioactive waste that ensures non return of the relegated material to the biosphere. At the same time, it affords inaccessibility to eliminated weapons material. The principle involved is the removal of the material from the biosphere faster than it can return. It is considered that ‘the safest, the most sensible, the most economical, the most stable long-term, the most environmentally benign, the most utterly obvious places to get rid of nuclear waste, high-level waste . . . The subductive waste disposal method forms a high-level radioactive waste repository in a subducting plate, so that the waste will be carried beneath the Earth’s crust where it will be diluted and dispersed through the mantle. The rate of subduction of a plate in one of the world’s slowest subduction zones is 2.1 cm annually. This is faster than the rate (1 mm annually) of diffusion of radionuclides through the turbidite sediments that would overlay a repository constructed in accordance with this method. (Rao, 2001, Current Science 81:1534-1546)
Why should I care about dirtying-up space? I already asked you for an explanation and you haven't provided one.cyrusabdollahi said:But its sad that you don't care about things like that as well.
What are you talking about?!? The quote you were responding to said nothing about the planet. But if you haven't gathered it from my posts, my position is that we need to immediately build another 200 nuclear plants to take over the capacity currently in the form of coal. Air pollution is the #1 environmental problem facing the world today.You should want a clean planet for your kids and their kids.
Obvious to you, but how reasonable is that really? You won't be able to get people to give up heating and air conditioning, which is what would be required to cut our usage in half just to eliminate coal power. Even if you could force it, why would you want to? It would utterly destroy the world economy.Its faily obvious the solution to the problem should be strict controls on how much energy we use, and looking for cleaner alternatives when possible.
Of course - if we really wanted to, we could all stop using electricity altogether. The question isn't what is possible, the question is what is reasonable. It is not reasonable to think we can reduce our energy usage by half without significant alteration of our way of life.If we *really wanted to* we could, as a nation, drastically reduce our power usage.
It is not reasonable to think we can reduce our energy usage by half without significant alteration of our way of life.
The energy crisis is not localized to the US. Other developing countries, like China, stand poised to take the crown of "most wasteful country" in the next century anyway. It just happens that, at the moment, the US is the world's largest consumer of resources per capita -- it won't always be that way, but some country will always be #1.
This discussion does not need to be derailed into a discussion of how the "American lifestyle" is the root of all evil. I agree that proper education and better efforts for conservation are very important, but I disagree that Americans are somehow so different from other people that they can be uniformly characterized as "wasteful" or that they deserve to bear the burden of the entire world's energy problem.
It's true that Europeans get by with lower consumer energy expenditure. Why? Because their homes are generally much, much smaller than American homes. Why are American homes so much bigger? Is it because Americans are greedy bastards who want to see the destruction of the planet? In general, at least: No. It's because America has more land, and larger houses are within the economic means of a larger number of people -- so we buy them.
They're not "better people," they just have a different geographic and economic environment.
Even if residential users cut their energy use in half (which is perhaps possible, though very difficult to achieve), the total energy consumption of the US would decrease by only 20%. Substantial, but not enough to eliminate the energy crisis.
Do you have some evidence for this claim about American houses being much smaller 50 years ago?cyrusabdollahi said:Well, look back 50 years. The size of an average house was much smaller. People used a lot less, and saved a lot more. Their lives were not in the 'dark ages.'
Are you aware that Canada's per capita energy is 17% larger than that of the US? (Source: DOE 2001 http://www.eia.doe.gov/emeu/cabs/carbonemiss/chapter2.html )I never said they are any better. I am just showing that you can live very well without the need for so many extra niceties that use power.
Do you think you're the first person to realize that more efficient industry yeilds greater profits? Do you think industries are not already trying to maximize their efficiency? Do you have any specific methods by which industries should magically increase their efficiency without affecting their economic position, or do you only argue in vague, uninformed, accusatory tones?Yeah, I think we should put money into making industry more efficient. They would make more money, and we would use less energy, win-win.
Japan has nowhere near the energy-intensive industrialization as does the US. You're arguing out of ignorance.Japan, highly industrial, but they are also very careful in how they use their power.
I agree that we should set an example -- I agree that we, as a nation, could do more to conserve resources. I disagree strongly that there's some magic bullet to be found, or some individual people who deserve to have fingers pointed at them. We happen to live in the most industrialized country in the world, and thus use the most energy. The two go hand-in-hand, and no amount of your enviro-babble cooing (e.g. "Ooh! let's just reduce consumption by 50%! It's not so hard! Let's just eat ice cream in the summer!") is going to cut our energy use in half without affecting every economy on the planet.As Americans, we should be setting an example to the rest of the world on how we treat the environment and how we use energy. I think there is allot we could do, that would influence other countries as well. And that would have a HUGE impact on the world.
Leaving aside environmental ethics, there are practicle problems with using Earth orbit as a dumping ground. Already Norad keeps track of thousands of manmade space objects, most of which serve no useful function anymore. These are a hazard to space navigation. And if any of the nuclear waste containers collided with each other or something else, they will break apart into hundreds or thousands of smaller particles that increase the threat. We're back to the question of intergenerational ethics again: it's morally wrong that we dump the problem of monitoring thousands of radioactive packages in Earth orbit onto future generations. Moreover, as space travel becomes more common, there would little to prevent a bad guy with a spaceship to go get one of the containers to make nuke bombs or dirty bombs out of. Until a space elevator or something similar is built that can reliably launch trash into the sun, the idea that nuke waste can be sent into space is idle speculation at best.Russ said:Why should I care about dirtying-up space? I already asked you for an explanation and you haven't provided one.
One technology that could do this that is right around the corner is LED lighting. These are an order of magnitude more efficient per lumen than incandescent light bulbs. Even florescent lights are now old-fashioned.Cyrus said:Yeah, I think we should put money into making industry more efficient. They would make more money, and we would use less energy, win-win. I think 20% of the power saved by a country that uses the most power in the world is quite a respectable achievment. It would do a lot of good. Look at Japan, highly industrial, but they are also very careful in how they use their power.
Yeah, just drive around some older neighborhoods, and you'll be able to see for yourself.chroot said:Do you have some evidence for this claim about American houses being much smaller 50 years ago?
Sure, and don't sweat it. Disagreements happen, so do agreements. And I don't hold grudges (too heavy).cyrusabdollahi said:(Look I am a nice guy see!?)
It's colder up north though. Since economies and lifestyles are very similar, this difference could be just heating costs.chroot said:Canada's per capita energy is 17% larger than that of the US
I wouldn't like my planet to share an orbit with all this waste either. Dumping in the Sun would be a more permanent solution, but a more costly one. As I understand it, you need to cancel out the speed of the Earth's orbit in order to achieve this. If you don't then the load will simply assumes a lower orbit instead of truly falling in. So adding up escape velocity of 11.2 km/s and our planet's orbital speed of about 30 km/s, each load has to be accelerated to 41.2 km/s to achieve the result. If anyone has information on the fuel and rocket cost required to do this for a ton of material, we can guesstimate the cost of such permanent disposal.WarrenPlatts said:there are practicle problems with using Earth orbit as a dumping ground.
It's an intriguing concept, but aren't there a lot of unknowns as to what truly happens at the core of the Earth? Have these geological theories been verified? The concern of course is about just throwing our waste in some inaccessible area that is outside our control and assuming that everyting will be fine.WarrenPlatts said:The subductive waste disposal method, however, is a concrete proposal that is economical and permanent, and it might just work.
Are you aware that Canada's per capita energy is 17% larger than that of the US? (Source: DOE 2001
Canadian electricity generation in 1999 totaled 567.2 billion kilowatt hours (bkwh), of which 60% was hydropower, 26% was conventional thermal power (oil, gas, and coal), 12% was nuclear generation, and 1% was derived from other renewable sources.
Canada is the G-7’s largest per capita electricity consumer. To a considerable extent, this is because of Canada’s large, hydro-powered aluminum-manufacturing sector. Between 1980 and 2001, Canadian per capita power consumption increased an average of 1.0% per year, from 13,100 kwh to 16,200 kwh.
Japan has nowhere near the energy-intensive industrialization as does the US. You're arguing out of ignorance.
The theory of plate tectonics is one of the most well-confirmed scientific theories known to humankind. There is a lot less disagreement among geologists regarding the reality of plate tectonics than there is among cosmologists regarding the reality of the Big Bang.Orefa said:[Subductive waste disposal is] an intriguing concept, but aren't there a lot of unknowns as to what truly happens at the core of the Earth? Have these geological theories been verified? The concern of course is about just throwing our waste in some inaccessible area that is outside our control and assuming that everyting will be fine.
Rao 2001 said:The waste will be carried beneath the Earth’s crust where it will be diluted and dispersed through the mantle. The rate of subduction of a plate in one of the world’s slowest subduction zones is 2.1 cm annually. This is faster than the rate (1 mm annually) of diffusion of radionuclides through the turbidite sediments that would overlay a repository constructed in accordance with this method. The subducting plate is naturally predestined for consumption in the Earth’s mantle. The subducting plate is constantly renewed at its originating oceanic ridge. The slow movement of the plate would seal any vertical fractures over a repository at the interface between the subducting plate and the overriding plate.
And your point? Are you suggesting that all countries should be able to produce 60% of their energy from hydro? This obviously is not the sort of thing one can legislate; there are only so many rivers.cyrusabdollahi said:Well, the majority of their electricity is from hydroelectric.
But cyrusabdollahi had his panties all in a twist about how people could just make such small changes as "wearing layers" to slash heating costs by half. It appears to me that those damn arrogant, wasteful Canadians aren't wearing nearly enough sweaters, and their wasteful, disgraceful lifestyle is driving the whole planet into ruin. That's what you meant, right cyrusabdollahi? Or was your irrational attack limited only to the US, which actually uses less energy per capita?Orefa said:It's colder up north though. Since economies and lifestyles are very similar, this difference could be just heating costs.
Hey, no problem, let's remove the industry. Canada used 403 million BTU per capita in 2001, while its entire industry used 2,680,111 terajoules, or 78.4 million BTU per capita (with a population of 32.4 million people). That means that Canadian residential users alone -- the ones who apparently are such arrogants pricks that they won't wear sweaters to save our planet -- used almost as much energy (324 million BTU per capita) as the average US citizen including its industry (342 million BTU per capita).DOE said:To a considerable extent, this is because of Canada’s large, hydro-powered aluminum-manufacturing sector.
You really need to brush up on those reading skills before entering these kinds of debates.cyrusabdollahi said:Perhaps I was not clear. What I was trying to convey was the fact that the standard of living in Japan has gone up significantly in the last ~30 years, while the power consumption has remained relatively neutral.
DOE said:Japan’s per capita energy consumption increased an average of 1.7% per year between 1980 and 1996. From 1997 to 2001, however, its annual growth rate was -0.1%, which likely reflects the country’s economic downturn. Japan’s low overall per capita consumption rate is indicative of Japan’s comparatively smaller share of energy intensive industries.
DOE said:The United States remains the second largest per capita electricity consumer in the G-7 behind Canada. U.S. per capita electricity consumption grew at a comparatively modest pace between 1980 and 2001 -- an average of 1.5% per year
Chemical waste?? I thought this thread was about nuclear power! Quit trying to change the subject to support your enviro-babble!cyrusabdollahi said:if things don't get better, and we are not careful in how we consume, we will have lots of chemical waste accumulating from years and years of dumping unnecessarily.
But cyrusabdollahi had his panties all in a twist about how people could just make such small changes as "wearing layers" to slash heating costs by half.

I never said anything of the sort about Candians, you did. I also never said wearing sweaters would cut it in half, you took my words out of context, thanks. You are putting words in my mouth. Now this is just getting out of hand. I am not going to get into a shouting match with you, that was not my intention. End of discussion, goodbye.But cyrusabdollahi had his panties all in a twist about how people could just make such small changes as "wearing layers" to slash heating costs by half.
I snoozed off there, but to reply to this (and other member's posts), I was referring to population control globally (which would decrease the need to enter richer countries illegally):Azael said:Trying to controll the population of the rich countries would be totally wasted effort since many of those countries already have aging and diminishing populations. Only imigration keeps the numbers up.
In china, india, middle east population controll would help to prevent a explosion in power usage. But in the western world I se no need for it at all, it would probably hurt our societs a lot to try and keep population growth down.
Goverments need to step in and restrict energy consumption if anything is to be done.
But if the people have a chooise totally giving up some quality of life or wanting more nuclear power plants no one would vote no to nuclear power. I sure as hell wouldnt.
