Re:Seriously, WTF?
Again, that's a common fallacy. It depends on how you go about reprocessing. The current once-thru fuel cycle actually results in more and purer plutonium in the waste stream than an IFR would. IFR's can burn up all of the current nuclear waste and all of the 'pure' plutonium from dismantled nuclear weapons. I'd say that's a reason to REQUIRE IFR reactors and reprocessing. 200 year waste with essentially no useful isotopes in it is a clear win over what we have now (that being lots of terrorist-bait in poorly guarded swimming pools at reactors sites all over the country).

Re:Seriously, WTF?
Patently false, unless you limit yourself to the retarded design we currently use. Using IFR technology, there is enough fuel for 100,000 years.
-
I'm all for this, IF...I'm all for this, if it includes research into IFR technology. If you haven't read this article, please do. I know it's biased toward IFR technology, but even if 10% of what the scientist says is true, we should be researching the hell out of it! Here's Wikipedia's take on the IFR.
The current reactor design is antiquated and hobbled by President Carter's decree that we will not reprocess nuclear fuel. So instead of extracting 90+% of the energy in the fuel and having 100 year nuclear waste, we extract 2% and have 10,000 year waste with the once-thru fuel cycle. Real smart, Jimmy. And he was a 'Nucular Engineer'! -
Re:Doltand you have been sipping the old socialist toilet water. Sprayed into your mouth by Obama and his comrades. You are calling US democrats socialists. In that case you really have no idea what a socialist is. They are light weight psuedo-socialists at most. I asked for ONE example of a country the size of the US with successful socialized healthcare Of course you did, because you knew that it would be impossible to find one. (Either that or you are an idiot)
All the countries he listed except for Canada are in the top 25 countries in the world. And if you remove third world countries, most likely in the top 10.
Actually, I don't get why scaling came into the discussion in the first place. It seems to work roughly similar here in Sweden (8 million) as it does in very much large countries such as Canada, Germany or France. Why is it suddenly so different when you jump up to the size of the US? but anything beyond that is a very long waiting list and most just come to the united states. Ok, that confirms that you are a rich spoiled libertarian atleast. Only rich people can afford coming to the US to get their special treatment, except maybe for a few specific cases where there was a lack of basic medical equipment in Canada.
More likely though is that you are just lying through your teeth. You don't think the liberal media lies on a constant basis to push agendas? I have no doubt about it. They lie less than the right wing (as in top run) media does though. With socialized health-care, we would have one large monopoly run by the most inefficient business there is: the government. The goverment isn't a business. And it doesn't seem to be the least efficent either considering goverment run health care seems to cost less per capita than the same US run health care that doesn't produce better results on average. Here is a nice example of how great french health care [bbc.co.uk] is (since you did include it on your list). Some issues with efficency is your great complaint. Let me strike back with this one. The US is so inefficent that it fails to treat 1/6 of it its own population. (and that is not including those who are under insured)
http://news.bbc.co.uk/2/hi/americas/7420744.stm
Oh, and if you want to find some dirt on my country's health care, I'll just go ahead and provide it for you from one of your own right wing "think" tanks (aka. propaganda center). I never said Swedish health care was perfect, but I still think it beats the US by far.
http://www.nationalcenter.org/NPA555_Sweden_Health_Care.html
Yes, Sweden have some problems with queues, and the conservative think tank is not shy on focusing on it as it wants to glorify privatized health care. Of course it completly fails to mention that Sweden is top class when you actually get your treatment, which among other things is evidenced by our good average life span.
Ok, that probably reinforces what you believe. That the rich should pay and get their treatment directly, while the poor should shut up, die and go to hell. -
Re:So...To paraphrase another reply, "So you haven't read up on modern reactor design?"
Because of Jimmy Friggin' Carter we have the once-thru fuel policy that extracts less than 2% of the available energy from the fuel, and leaves waste that's hot for 10's of thousands of years. With a little work, we could have modern, safe, efficient nuclear energy with waste that's hot for only hundreds of years, with LESS of a plutonium proliferation risk that we have RIGHT NOW.
I salute India's research into making reactors that 'burn' thorium, since they've got quite a bit of it. -
Re:i couldn't have said it better myself
It depends on how you utilize your resources. Uranium isn't the only fissile or fertile fuel around, and we're currently only extracting 1-2% of the available energy in our current once-thru reactors. See this Q&A for more information on IFR technology.

Re:That's nice and all......since the last N-plant went active in the US...
It's alright - you can say the 'N' word! Even some environmentalists are saying it (gasp!!) Go ahead, it's easy. Nooo-cleee-urrr. Nu-cle-ur. Nuclear. There, that wasn't so hard. I think we've made great progress.
Obligatory content: I'm convinced that the only way out of our energy 'crisis' is to adopt IFR technology. This interview in particular spotlights its technical merits and the political stumbling blocks that have been thrown in its path. -
Legal PrecedentOne attorney for BJB said there were no First Amendment problems, invoking a U.S. Supreme Court precedent dealing with an intercepted conversation played by a radio station...

Here is your correction
The IFR was started by poppa bush. It was within 3 years of completion. Sadly, Clinton killed it (did not want to, but it was part of a deal with congressmen, in particular kerry; IMHO, this was the single biggest mistake that clinton made; far worse than lying). The nice thing about the IFR is that it is 100% based on past and current tech. There was nothing new to RD, except to integegrate these. The idea is that you load the ractors and then when fuel is used up, a set of robots bring out the fuel, seperate it, add new fuel while re-process the old fuel right on site. Since it is a fast/breeder reactor, it does create plutonium. But NOBODY would have the capability to get close to it. After about a 100 years, the reactor is shut down permanently, and a VERY small amount of trans-uranic waste is left over that decays within 150 years. THis is the best paper to read
ITER is a TEST. Purely a TEST. It is HOPED that it will generate excess energy, but we do not know. The chances are that it will. But even then, it will be 2050 before it is really known. Then it will take another decade or two to get prototypes going, etc. etc. IOW, the earliest that you will see plants on-line is about 2060-2070. That is far too far away (though it is good that we do it; need to know).
We can still start up the IFR, but W. says that he is interested in doing it, but appears to be doing nothing. I am guessing that this will happen in the same way that our energy research was funded (W spoke about America's research via SERI, though he had just cut 10% of their budget). -

-
Are we talking about the same device?
No, there are no designs that don't produce long-lived waste. The IFR concept which you referenced never got beyond a small-scale prototype stage.
Because it was canned due to political concerns--it was at the time a very promising project, and we'd have had a full-scale prototype for more than a decade by now if it hadn't gotten canned.Pointing to that as a 'design' that doesn't produce long-lived waste is incorrect and misleading since, at best, it only reduces the waste volume.
From the FAQ: "Some constituents of the waste from thermal reactors remain appreciably radioactive for thousands of years, leading to 10,000-year stability criteria for disposal sites. [...] With IFR waste, the time of concern is less than 500 years." I've seen different numbers put forward in different articles, but the theme seems to be that the waste remains dangerous for centuries rather than tens or hundreds of thousands of years, this being a primary difference between the IFR design and other reactor types. By what basis do you claim that "at best, [the IFR] only reduces the waste volume", and by what basis do you claim that the waste is as long-lived as that from current reactors?More importantly, there are many years of development needed before it would even be known if the IFR concept were operationally feasible.
"... Argonne National Laboratory, which was about three years from finishing a study that was expected to establish firmly the technical and economic practicality of the concept." I suppose "three" is kind of like "many". Either way, if (as I pointed out previously) it hadn't been cancelled when it was, we'd have had an answer to the feasibility question during the Clinton administration. -
Re:Nuclear waste
Here is from the original designer of the IFR. It can be restarted up. W. has a number of companies pushing to get ahold of our work. It would be useful to do that as fast as possible.

the real problem was the class of problem revealed
TMI and Chernobyl revealed classes of nuclear disasters that the industry had said were not supposed to occur. There were so many safeguards and so much redundancy that meltdowns simply couldn't happen. Well, they did. The reactor designs (two very different designs in these cases) both implied that meltdown and release of radioactive gas, water vapor, (and in the case of a full meltdown the radioactive elements used as fuel) was inevitable if the redundant cooling systems failed.
The human cost of Chernobyl was quite a bit higher than people realize. Given that both of these disasters were far smaller than they could have been, that cost should be sobering.
Chernobyl Legacy, a photo essay by Paul Fusco
New reactor designs might make the risk/reward trade off for fission power more reasonable. (See: New use for nuclear waste) However, the designs from the sixties and seventies that are running today really ought not be near cities or in areas where it would suck to have to fence off a couple hundred square miles for a few centuries after a disaster. -

Re:Studebaker Nuclear ReactorsIgnorance is a wonderful excuse. And that is the reason why so many of us keep trying to push it and teach others about this. This reactor would be built, loaded, ran for a hundred years, then upon decommision, the spent fuel (transuranic) would be able to be put underground and would be safe in under 100 years. The interesting thing is that the bulk of the fuel for it, would come from what is planned to go into the ground that would need 1000's of years before it is safe. In addition, if we started building these within the next decade, then all the fuel that we have now would power ALL of AMerica's need for the next 100 years. And that is without any more mining. The really cool part of this? That it solves SO many issues that America has.
- You are opposed to the long term radiactive waste? This burns up nearly ALL the energy that is left to cause 1000's of years of radiation.
- Opposed to paying terrorists to blow us up? So am I. This would enable a true electrical society.
- Tired of a yo-yo effect on pricing? So am I. Nearly all of the fuel that would be loaded in these, we have ready to bury in the ground. Once loaded, there would be no change in the fuel price.
- Do not like the safety record of the nuclear industry (though it is actually excellent)? This has the advantage that it is a TOTAL passive safty. The only way that it is going wrong is if you can blow it up (which would require a nuke to do), or if you can bend the laws of physic.
- Do not like the idea of plutonium being produced. Well, this is a breeder reactor so there is plutonium, but wrong kind AND it is all enclosed. NOTHING could get close to it until the entire system is shut down. Permantly.

Re:PredictionMe too, but most with regard to all of the barely used nuclear fuel rods languishing at reactors all over the country. There's a ton of energy left in them, and by burning up the actinides you're left with waste that's 'hot' for a faction of the time. From this Wikipedia article:
Compared to current light-water reactors with a once-through fuel cycle that uses less than 1% of the energy in the uranium, the IFR has a very efficient (99.5% usage) fuel cycle.
andAnother important benefit of removing the long half-life transuranics from the waste cycle is that the remaining waste becomes a much shorter-term hazard. After the actinides and transuranics are removed from the spent fuel, the remaining waste elements have half lives of a few decades at most. The result is that within 300 years, such wastes are no more radioactive than the ores of natural radioactive elements.
This interview with George S. Stanford, Ph.D highlights the history and potential on IFR's.

Re:"God Says it"
um
...The Pilgrims weren't all Puritans. In fact, the Mayflower Compact was writtten on board the Mayflower to try to prevent mutiny by the majority on that ship who were not in it for religious reasons but rather, for profit (which was the primary motivation for almost all colonies.
Converting the people living in the Americas to some kind of faith or another was more the motivation of Spain, who had (in 1492!) only just rid the Iberian Penninsula of non-Christians. Occasionally, some of the English Colonists would pay lip service to this ideal, but it was rarely policy.
The 37 Separatists (Puritans) fleeing religious persecution who were on board the Mayflower had set about trying to convert their fellow shipmates. And when it was discovered that they were strongly desirous of creating a theocratic movement in the new colony, their shipmates immediately threatened to let them off right where the boat was at the time (in the middle of the Atlantic) where they could set up their government in any way they preferred.
Since the victors tend to write the history books, we tend to be particularly focused on these particular Separatists who narrowly missed setting up a theocracy in salt water. Over the course of the years following the original Mayflower landing, more Puritans emigrated and it is these people who began linking governance with their religion. They were primarily interested in making money, realizing the trade in shipbuilding timbers and exploitation of the costal fisheries was making a number of the colonists wealthy and land in the colony was available at low cost.
And, rather than indescrimately kill all Native Americans, the earliest colonists were beneficiaries of a French trading mission that had passed through the area five years before the Mayflower landed, unwittingly exposing their trading partners to European diseases. It is said that influenza killed off half of the tribal population in the area the first year and when the Mayflower landed, the colonists found the land empty.
This stands in sharp contrast to the Roanoke colony which lasted some 10 months, the survivors of which were returned to England due to increasingly hostile Native Americans.
If you look at a map of New England, you'll see many towns and cities with the word "field" in the name. The reaon why this reoccurs is due to the habit of the Europeans referring to these areas as clearings. Now these areas wold not have been cleared had the Native Americans cleared them but, due to disease sweeping through the indigenous populations whenever contact was made with the Europeans, these clearings had been abandoned. Europeans called a "clearing" a "field."
The Plymouth colonists' first contact with the Native Americans was in March, 1621, when Samoset, a Wampanouy, entered their encampment and began conversing with them in English, which he had picked up from English sailors in the area. Samoset and later Squanto, a Massasoit, were interested in these new white settlers because they wanted to form an alliance between them and their tribes in order to be able to fend off incursions from other tribes. They figured that the European technology might help them resist encroachment on their lands and that an alliance would help them both from a military standpoint and a trade standpoint. But the Europeans would never have been a consideration had their tribe not suffered substantial losses in population due to disease.
Now, I have read history and part of it is due to my ancestry being from the founders of the Cape Ann colony, which settled in Massachusetts in 1623. Many relocated to Connecticut by the 1680s. While the Puritans were very strict in their adherence to the tenants of their religion, you have to understand that they did not try to convert Native Americans--that was just not their aim. I

Humanity as cause of GW not certain
Whatever happened to the vaunted Slashdotter cynicism towards FUD? I know things trend leftward here on
/. but don't facts and reality have any weight any more? Check out this website with supporting cites of Crichton's thoughts that the "Panic now" approach to global warming is not the best way to go: http://www.heartland.org/Article.cfm?artId=16260#r ight The argument I always stick on is that Mars is warming as well and there is no way that our SUV's could possibly warm Mars. Earth has been warming and cooling periodically since its inception. Let's find out if action is required before taking drastic steps that WILL cause deaths and misery among the poor. For example, in America if gas goes up to $6 a gallon then we can mostly suck it up. . .except for the very poor. This type of thing will raise food prices (how do you think food gets to the stores?) and limit the employment options for the poor to travel to find the good jobs by raising the cost of transportation. And that's just in America, what about in places that are really desperately poor. When you make $200 a year a small increase in the price of gasoline takes a huge bite out of your living standard as every product from food to building materials has to get there with gasoline. Bjorn Lomborg in his book, "The Skeptical Environmentalist" pointed out facts like these and was pilloried as a heretic for it. I don't care about agendas, I only care about facts and results. I refuse to support actions that the facts don't currently support as necessary when the guaranteed results cause misery and needless deaths. Do you guys remember DDT? Environmental extremists caused it to be taken off the market and not used any more. This has resulted and in millions upon millions of deaths for no good reason. Oopsy. http://www.spiked-online.com/Articles/000000005591 .htm "Malaria is on the increase in all tropical regions of the planet - especially in Africa. In 2000, the disease killed more than one million people and made 300 million seriously ill." There are many, many, many peer reviewed serious scientists who think that Global Warming cannot conclusively be blamed on human behavior. Further, others point out myriad BENEFITS to global warming, so even if it is caused by humans it may be a blessing and increase quality of life. http://www.nationalcenter.org/NPA165.html "If history is any indication, greater precipitation may be only one of many benefits of global warming. For example, between the 10th and 12th Centuries, when the temperature of the planet was roughly 0.5 degrees Celsius warmer than it is today, agriculture in North America and Europe flourished and the southern regions of Greenland were free of ice, allowing cultivation by Norse settlers.

Words mean things
"Infant mortality" has different definitions between _states_ in the USA. Was it a miscarriage, or did a baby die? It depends on which state you're in. Comparing between countries will give you some real apples and oranges. This is maddening if you are in a state with a broad definition of "infant mortality" and your hospital is getting bad quality outcome numbers because of the definitions your state legislature made.
Also, one would expect that infant mortality would be highest in a country with the highest risk obstetric patients, wouldn't we? Let's see. A country where women with careers wait until their 30's to have babies instead of their teens and twenties. Where, as a result, infertility treatments and therefore multiple gestations (twins, triplets, etc) are common. Where, as a result, the neonatal ICUs are crammed with babies from about 30 weeks gestational age (having been in the uterus for only 3/4 of the celestial committee's recommended stay.) One could easily make the assumption that the more money a country is willing to spend on medical care, the higher their infant mortality would be.
The actual numbers, sampling biases, etc are much more complicated than this, but anyone who thinks Cuba's medical care is better than that in the US is a bit confused or deliberately misleading others in my opinion. I wouldn't want to be a 30 week gestational age infant in Cuba.
Here's an article that gets into a little more detail, but really the whole socialized medicine argument is like debating creationists. You aren't going to change their belief with any evidence. I just get sick of the infant mortality / longevity comparisons which are so obviously inane.

Possible Hydrogen source: Integral Fast Reactor
Why not build an Integral Fast Reactor (FAQ), and use the electrical output to electrolyze water, or use the thermal output of a Lead Cooled Fast Reactor to thermochemically crack water into oxygen and hydrogen.
As far as waste is concerned, the Integral Fast Reactor waste products have a relatively short half life. From the Wikipedia article: "The result is that within 300 years, such wastes are no more radioactive than the ores of natural radioactive elements." -
Re:crap!
This is a non-issue. With the typical fuel cycle for a fast reactor, producing weapons grade plutonium is basically impossible. It can be done, but you would need to run a completely different fuel cycle, explicitly for the purpose of producing plutonium. The only way for this to go unnoticed is to build and operate your own private reactor, so there is no more inherent danger.
An added benefit though, is that these reactors are capable of burning plutonium. As such, they can be used to dispose of our current stockpile. Actually, they can burn all sorts of stuff which is currently considered waste. After some on-site reprocessing, you continually send most of the material back through. (Current reactors only utilize something like a few % of the fuel and the remainder is the highly dangerous and long-lasting waste that everyone is so terrified of.) The minimal waste that is left over in an IFR, will reach background radiation levels in ~300 years.
Perhaps just as important, they are inherently safe from meltdown; if the cooling system fails, the reaction stops. This has even been tested in practice, and works as expected. Basically, it is a nearly ideal source of power from almost every aspect. All of the dangers and drawbacks of current designs have been addressed--what remains is to educate people about this clean, safe, and abundant source of power.
Below are links to the Wiki, and a sort of FAQ about the IFR. The latter addresses any concerns about proliferation.

Re:we already have clean nuclear power technology
I agree that "fast nuclear reactor" is a fine name. I think you'll be glad to know, however, "the fact that it produces high grade (bomb grade) nuclear fuel" is actually not a fact. Check out the following link, which discussed the IFR (Integral Fast Reactor) specifically relating to proliferation risk: http://www.nationalcenter.org/NPA378.html. Wikipedia also has some useful information.
While it is true that a fast nuclear reactor can be rigged to produce more plutonium 239 (the kind of Pu that bomb makers want) than a thermal reactor (70-80% of the fuel vs. 60%) it is so contaminated with exotic transuranics that are highly radioactive that it's practically useless for making a weapon. A bomb maker wants at least 93% pure Pu239, so even 80% is not good enough, but the shielding required to deal with the contamination of the other highly radioactive elements that are present negates that "benefit". Waste from a thermal reactor would be much easier to turn into a bomb, but even so, no such weapon has been produced in the decades we've had nuclear technology. Uranium enrichment is so much easier, and easier to keep secret. You start with abundant, stable, U238. Who'd want separate out exotic elements from a substance you'd have to keep behind 6ft thick shielding? Try transporting that.
As for the environmental argument, fast nuclear reactors can not only burn U235 like a thermal reactor (which is 1% of naturally occurring uranium) they can burn plutonium from decommissioned weapons, "waste" fuel from thermal reactors and U238 (which is 99% of naturally occurring uranium). Once you've burned all the uranium and plutonium, what's left is highly radioactive, which means that it has a low half-life, which means that it decays to a safe level much more rapidly. We're talking hundreds instead of hundreds of thousands of years. That means that planning to keep the waste onsite makes sense.
An even larger environmental benefit from fast nuclear reactors is reduced mining. Since these advanced fuel cycles can burn more kinds of material (i.e. the vast majority of transuranics) instead of only burning 1-2% of an isotope of uranium that is 1% of naturally occurring uranium (we're talking four orders of magnitude difference), the environmental benefits of reduced mining activities are enormous. Moreover, not only do you not need Yucca Mountain, but because we can burn "waste" we've already generated as fuel, we already have stockpiles of fuel that will last us for centuries. This actually solves yet another, often overlooked, problem with conventional nuclear: we're running out of U235. We probably have 100years worth of U235 in the ground. With a fast nuclear reactor we can burn just about anything.
Not only does an advanced fuel cycle, like that used in the IFR, limit proliferation, and limit the lifetime of the resulting waste to hundreds of years instead of hundreds of thousands, it can be built in a passively safe reactor. The IFR relied on the laws of physics to prevent meltdown. First, the fuel in the IFR was metallic instead of ceramic. This means two things. First, metals conduct heat much better than ceramic, increasing the rate of thermal transfer away from the fuel. Secondly, the fuel expands as it heats, shutting down the reaction. Finally, the fuel was placed in a pool of liquid sodium (the fuel itself was clad in steel) at atmospheric pressure, instead of using pressurized water as the primary coolant. The IFR relied on convection in the liquid sodium to carry heat away from the fuel instead of pumped pressurized water. So, what happens when all active (secondary) cooling is removed? They actually did the test. The fuel heated up slightly and was then passively cooled by convection currents in the liquid sodium carrying heat away from the fuel as the reaction shutdown.
So, an advanced fuel cycle, like was used in the IFR, can have dramatic benefits to the environment by reducing not only long term waste storage requirements, but -

Re:Doom and Gloom
Uhhh... I thought the parent was talking about not worrying about global warming.. I think you pulled this "Rules free" thing right out your ass.
The point your missing is: Now no one has to worry about spending rediculous amounts of money
http://www.nationalcenter.org/NPA328.html to try and slow down a problem that we have little to no control over. Environmentalist are going to have to find a different way to persuade us all from polluting now! -
Re:US Constitution vs. Censorship
I'm sure that you understand there are reasonable limits to the freedom of speech. For example, no one seriously argues that fraud(deceptive commercial speech) is a protected right under the first amendment.
Any limitation on political speech should be denounced by all freedom-loving people. I personally find McCain-Feingold to be particularly troubling. Potential limitation of the freedom to publish pornography could be seen as the first step on the slippery slope to fascism. I think the more realistic translation would be a minor contraction in the accepted breadth of what rational people consider unlimited speech. -
Kyoto
What is certain - no matter whose model you use - is that the Kyoto accords will not appreciably affect CO2 in the atmosphere, and still less will it affect climate, while it will cost many trillions of dollars in direct costs and lost growth.
At one tyme I supported Kyoto and in the 2000 election instead of voting for whom I wanted I specifically voted against Bush. So it was with no supprise to me when he said he wouldn't support it once he got into office. However because of something he said I did some reseach, he specifically stated China and India along with other un/under developed countries didn't have any emissions targets. Sure enough in my research I found out he was right about that. So now as long as some are exempted from any emissions limits by Kyoto I too am against Kyoto. Back then both China and India were building new coal fired power plants that would put quite a bit of greenhouse gases out. However I still believe the US can and should do something. As for lost growth, I don't see it, if anything I see more employment a growth not less with a healthier environment. There would be more reseach into cleaner technologies and manufacturing jobs would be created in these clean(er) technologies. Solar energy for instance will require a boost in manufacturing pvs creating more jobs, distribution of and installation of PVs will create even more jobs as will periodic maintainance. The same will happen with wind genies, wind generators. Bioremediation and cleanup of brown fields will create more employment.
Also with Global Warming, if it's true, economic losses for businesses can be significant. Hurricanes need warm water to grow, and has been seen in Florida the last couple of years the state has been badly hit by one bad hurricane after another. Who suffers? Besides those killed, insurance companies have to make all those payments for damaged and lost property. To pay for those losses they raise their premiums so the insured pay more. About the only one who benefits from this are the construction companies.
And what of the spread of diseases and virii? Ebola for instance is spread by birds and mosquitoes, as warming happens mosquitoes will spread further north. I'd bet other virii can spread in the same way.
1. increased nuclear power investment, particularly fuel cycles that use the "waste" of current Uranium cycle plants (mostly Plutonium), or new Thorium-cycle plants.
At one tyme I was strongly against nuclear power, and am still wary of it, but as I learn more I think more and more that it may be an answer. For instance Integral Fast Reactors: Source of Safe, Abundant, Non-Polluting Power . And Nuclear Waste and Breeder Reactors - Myth and Promise
.Earth-based solar power, wind power, tide power, geothermal power, OTEC, biomass, and conservation will not provide enough energy to replace fossil fuels. Slower growth will just increase poverty and thus population, thus has no net long-term benefit.
Now as stated above I fully support some of these alternative energy sources.

coal vs. nuclear fatalities
People don't like nuclear power because of incidents like three mile island and Chernobly
,yet more damage is done each year by the cumulitive effects of coal/gas and oil plants.I read somewhere that more people die in coal mines in russia every year than the total death toll (including long term cancer deaths) from chernobyl. And chernobyl was a crappy design that would not be allowed in the US. Cancer death estimates vary considerably, however. Additional eurasian cancer deaths would have to be compared to polution related deaths from power plants (which kills thousands every year). Directly attributable deaths for nuclear power, per terawatt years of power generated are 8 for nuclear power, 85 for natural gas, 342 for coal, and 883 for hydroelectric (dam's break). Add some cancer deaths for nuclear and pollution related deaths from fossil fuels. And add global warming related deaths to fossil fuels. Commercial power plants have 11000 reactor years of operation in over 30 countries with two major accidents. That is about one accident per 100 power plants over the projected life of the reactor and future accidents are likely to resemble three mile island rather than chernobyl. And coal plants release more radiation into the atmosphere than nuclear plants (yep, coal contains radioactive material).
Average radiation exposure to 2 million people around three mile island was 1mrem compared to 6mrem for a set of chest xrays. Exposure at the plant boundary was 100mrem which is less than the annual background exposure. So, even if you were standing near the plant, your total lifetime radiation exposure was increased by about 1.2%.
Studies indicate that US Nuclear reactors will survive a direct hit from a 767.
Nuclear waste disposal is an issue. Integral Fast Reactors have the potential to reduce the magnitude of this problem considerably.
About a year ago, James Lovelock, of Gaia fame, proposed nuclear power as the only alternative that could stem global warming in time
There is one new technology that is more suited for oil replacement and could be a decent alternative to nuclear as a fossil fuel replacement: Thermal Depolymerization . That is a new technology but a pilot plant is producing 400 barrels of oil per day. When run off of plant (or even animal) material, the net greenhouse emissions are zero and the process consumes waste (and a wider variety of waste than other technologies) rather than creating it.
I live about 30 miles from two nuclear power plants (and the site of what might be the first new power plant built in the US) and less than half a mile from a research reactor.

Twisted PantiesBefore any U.S. Slashdotters get into a flame war about this, remember that in 1997 the U.S. Senate voted 95-0 in favor of specific conditions that had to be met before they would be willing to agree to the Kyoto Protocol draft or any other greenhouse gas emissions limitation. In other words, the Kyoto Protocol -- as written -- was effectively rejected by the U.S. Senate without a single vote in its favor.
Just food for thought.

Re:If it's so easy, why hasn't anyone done it?
This is grossly unsupported by proper engineering analysis and history.
If you read your own link, you'll notice the Indian's powered down their own NPP, just 8 months after it started to use just part of its fuel for their bomb, so they were using "fresh" fuel, and apparently mixing it with "pure" plutoniom they already had. Because of this, I don't think you've proven your point.
But the arguments that RGPU weapons are impractical have been thoroughly discredited
That depends on your definition of RGPU. If we're talking, and this was mentioned earlier in the thread, about Integral Fast Reactors, the answer is no. The fuel from this kind of reactor, is exceedingly difficult to use for weapons. So difficult to use in fact, that any country capable of doing it, is almost certainly technically capable of making even better nuclear bombs the conventional way like everyone else.
See here. -
Re:First you need to ask yourself these two questiThe Integral Fast Reactor concept attempts to answer to both questions.

Re:No differnces?Democrats use the courts to pass policies they know they could never be elected by supporting. So while Kerry wouldn't say anything in support, he would happily sit by while activist judges (of the sort he would be appointing) rammed it down our throats.
Do you ever get the feeling that our country has been through this kind of thing before?
Civil rights was rammed down America's throat, too. It wasn't the executive or legislative branch paving the way--it was the judicial branch. Without those "activist judges" going against the mainstream American values of the day, there's a very real chance that you'd see a "whites only" sign hanging in the window of your local Starbucks. Which was right--the judgement of the activist courts, or the will of the American mainstream?
This kind of thing is exactly why we have a judicial branch. Fundamental human rights aren't open to debate on the grounds of "what the majority is comfortable with". The founders were keenly aware of the "tyrrany of the majority", and they went to great lengths to keep the majority from trampling the rights of the minority. One of these safeguards is the judicial branch of the federal government.
Over the years, the American mainstream has maintained that blacks are worth 3/5 of a human being, that women are property, that the Irish are a race of sub-humans, that it is perfectly appropriate to sell and purchase human beings, that marrying an individual of the wrong race was a capital offense, and that Indians either needed to move out of our way or be killed. Today, the American mainstream believes that gays and lesbians shouldn't be allowed to marry those they love--or even enter into civil unions, for that matter. Occasionally, the Legislature or the Executive will take it upon themselves to right these wrongs. In most cases, though, it's the Judicial branch that steps in and upholds the individual's right to life, liberty, and the pursuit of happiness.
Be thankful that our highest court is not subject to the whim and fancy of American mainstream thought.

Re:What? We didnt blame Bush for it?Wait,...there is plenty of blame to go around! First, read up on the Kyoto Protocol. The protocol was negotiated in 1997, opened for signing in 1998 and closed in 1999. I am pretty sure there wasn't a signature spot for "Governor Bush". Contrary to popular belief however,... it was signed by the US. Gore signed the document, in a completely symbolic gesture. However, the US Senate had already passed the Byrd-Hagel Resolution which was really just a warning to President Clinton that if he sent the protocol to the Senate for ratification, it would fail. Incidently, the Senate vote on the resolution was 95-0, including Senator Kerry. As an excuse the Senator has said that the resolution was passed before the Kyoto protocol was finalized and was written so broadly that he pretty much had to.
Read it for yourself. It does say that the US should not sign any agreement unless all the countries are held to the same standard (currently 80% of the world is not restricted what-so-ever by the protocol - including China) and it shouldn't be signed if it would do severe damage to the US economy. It also says that if it is passed on to the Senate for ratification.. it needs to be delivered with an impact assessment.
To me - it all seems pretty reasonable.
-
Re:Hope this isn't used as an excuse...I never said that the protocol had been submitted to the Senate. If you had both my comment and the wikipedia entry, you would know that:
a. Gore did sign the protocol (which was symbolic only).
b. And that both Clinton and Bush decided to not pass the treaty on to the senate, citing the Byrd-Hagel resolution as strongly suggestive that the Senate would not ratify it.As for this:
The resolution was written so broadly that even strong supporters of the Kyoto Protocol, such as senators Joseph Lieberman (D-Conn.) and John Kerry (D-Mass.) voted for it. In doing so, Sen. Kerry said: "It is clear that one of the chief sponsors of this resolution, Senator Byrd . . . agrees
What was in the resolution that was so "broad" that "strong supporters" of the protocol had had to vote for this resolution? ... that the prospect of human-induced global warming as an accepted thesis with adverse consequences for all is here, and it is real.... Senator Lieberman, Senator Chafee and I would have worded some things differently... [but] I have come to the conclusion that these words are not a treaty killer."Here is the text of the resolution. Find the statement that was so compelling that John and Joe couldn't resist voting for it...
I've read it... it is one of the most straight-forward resolutions I have seen from the Senate.

Re:Radical Rogue 9th Circuit Court!the INDUCE Act couldn't "overturn the 9th Circuit's ruling"
Uh, last time I checked, statutes trumped common law in their jurisdiction. Moreover, new Federal law (INDUCE) would trump rulings on the old Federal law (found in 17 U.S.C.) made in a Federal Appeals court (MGM v Grokster).
As you rightly pointed out, the worst the Supreme Court can do is declare a law unconstitutional; however, even they have to wait for an actual "case or controversy". They can also overturn themselves, e.g. Brown v Board of Education overturning Plessy v Ferguson.
Now begins speculation. As far as INDUCE goes, it could be viewed as an end-run around Betamax, since the Betamax decision only applies to current doctrines of secondary infringement (obviously). The new 'inductive' doctrine would be a peer to the vicarious and contributory doctrines, and may or may not be subject to Betamax, since the Supreme Court didn't have induction in mind when they made the ruling.

Re:No matter..
1. Human error.
With 1st and 2nd generation plants this was true, but not with the later designs, where inherient safety was part of the design itself. Example: designs which have the reactor core with openings on its top sitting in some pool of liquid, all self-contained, with no means for the liquid to leave the chamber. If the core gets too hot the liquid expands, eventually reaching the openings at the top of the reactor, pouring in and killing the reaction. The only way for that reactor design to meltdown, would be for several basic laws of physics to fail simultaneously. (This was IIRC a Scandanavian design that I read about a few years ago. There are certainly by now other designs which are just as clever.)
2. Serious failures can also accur with modern reactors although the design is fundamentally different to the one used in Chernobyl. They are not immune just because of the way they are built (which is often claimed by energy groups). The different reactor design merely makes them more secure but not perfect.
See above. Tell me how a design that can only fail if multiple laws of physics and chemistry fail simultaneously isn't the closest anyone will ever get to perfect? Your example that you gave after the above quote is based on *old* reactor designs!
3. Fission itself is clean. But the nuclear waste is not. You cannot keep burying all the nuclear waste in some old mine for another 200-300 years. With a half-life period in the millions this is one hell of a legacy for our children.
Most of it doesn't have to be buried, actually. If the tree-huggers would stop blocking every nuclear power plant no matter the differences, we can build several integral fast reactors (IFR) which can burn the spent fuel from our current reactors for energy (as well as consuming all that weapons grade plutonium that is lying around). The rest? There are several promising ways to get rid of nuclear waste, including several methods involving deep insertion into the ocean floor at certain locations. Depending on who you ask, these ideas are not only feasible (although expense may be an issue) they are even safer than something like Yucca mountain, but unfortunatly politics has prevented further research into the idea because once the government decided on the Yucca Mountain site it stopped looking at other alternatives. Never mind that the tree-hugger's main strategy is to say no to everything, hoping that an escalating waste problem will prevent adoption of nuclear power. That may work here, but not everywhere else, while we remain moribund, countries like Japan and France are solving their energy problems with nuclear, and aren't the ones producing so much carbon dioxide.
4. What if something happens?
Indeed, we could get hit tomorrow by an asteriod and render this entire argument moot. Look, life is a gamble every time you leave your house, you have to look at the risk-reward ratio involved here, and it seems to me we are increasingly learning that there is a potentially *profound* risk, to a large portion of the 6 billion people on this planet, of continuing to produce carbon dioxide and releasing it into the atmosphere. All risks are relative. -
Re:No matter..
Chernobyl caused 31 deaths not including cancer.
[This post is in support of the parent, and really a response to the grand-parent]
Chernobyl wasn't an example of the danger of nuclear power, IMO, it was an example of the danger of *communism*. It gets really tedious having to point out to all these tree-huggers over and over again, that *nothing* like Chernobyl was ever built outside Soviet Russia, never would have been, and now that the USSR is gone, it *never* will again. Chernobyl, even when it was *brand spanking new* *massively* violated Western nuclear safety standards. For cryin' out loud folks, Chernobyl didn't even *have* a containment building!
The rest of the world has a containment structure made of at least 3 feet of concrete on all sides to keep a reactor explosion like the one that happened at Chernobyl from releasing any debris or radiation. The truth is, if Chernobyl had had a Western style containment structure, none of us outside of the USSR would ever have known about the accident, untill after the fall of the USSR, the accident would have been no worse then what happened at TMI. Remember, at TMI, half the reactor core melted down, but the containment structure was never breached, which is why there never was any significant, i.e. dangerous, release of radiation from TMI.
And since then of course, the rest of the world is now into the 3rd generation power plants, that are much safer than the ones we have now. Never mind the mini-reactor concept which would make a meltdown physically impossible because there literally isn't enough fuel to go critical. Or the integral fast reactor idea (IFR), which would result in a power plant that would produce a nuclear byproduct that was much less useful as potentially weapon's grade material, *and* it could *consume* the spent fuel of the current reactors (plus the leftover plutonium from weapons) we have now. We don't need to bury the stuff, it could be fed to an IFR and used to make energy! Unfortunately, the construction of a prototype here in the US (Japan already has some) was killed because our politicians misunderstood the technology (now how often does *that* happen?), and were convinced by the anti-nuclear folks that this was dangerous for proliferation, when its actually the exact opposite! And to top it all off? The cost to shut down the project was more than the cost to go ahead and finish it! ... Forget the damn lawyers, I say the politicians should be first up against the wall....
So we don't build any new nuclear plants (I figure when brownouts become commonplace in about 25 years, we'll rush build more coal and oil burners and to hell with the environment), continue to use old ones that are getting older, and therefore more dangerous, and while the rest of the world leaves us behind, we continue to rely on our trusty coal burning plants, and Middle Eastern oil, which, when you add in the cost of the wars we have to fight to keep the oil flowing, and the lives lost, is costing us a fortune.
But thats what we Americans want, we think cheap gas is some kind of God-given right of ours, that electricity is some kind of manna from heaven that doesn't cost much, so we keep driving our SUVs, we keep buring that dirty coal, and we keep sending our young people to the other side of the world to die fighting religious lunatics for crude, and still there are very few Americans who have recognized just how stupid and insane our energy policy has become.
Here on /. though, the tree-hugger's FUD is still going strong, so the status quo is still a go.
And people want to know why I'm so cynical about my own country.... [Sigh] -

Re:Ouch-Nuclear terror.To produce enough electricity to power the United States, you would need a little more than the area of Connecticut and Delaware in solar panels (Solar advocate stats, not mine). Only a handful of states could sustain themselves on wind. And if you think one state making most of the power for another is a good idea, I have one word for you: Enron. Hydroelectric never gave anyone thyroid cancer, but it has caused no end of ecological disruption in exchange for insufficient amounts of electricity. Tidal is a bad idea due to the fact that >95% of all life on this planet lives at a coastline; Getting energy from the tides means taking energy from those ecosystems.
Let's take California. Look at the number of hydroelectric. Look at the number of wind. How many nuclear? Hard to tell on that map. Just two. Two. Two nuclear plants supply about 20% of all electricity to the state. Two nuclear plants have had less impact on the environment than all other forms of mass electricity production in the state.
And for the record, it is possible to reduce waste dramatically. This can be done with breeder-burner reactors. My personal favorites are IFR/AFR designs. Breeder-burners process the long-lived waste into shorter-lived isotopes while producing electricity.
Now then, on to your other points one by one:The residents of Nevada are protesting the inturment of the nations nuclear waste in their backyard.
No, not all residents. There are many who aren't in opposition to the internment of the waste.
Questions for you: Do you believe that the current storage pools are safer than Yucca Mountain? Do you have an answer for the existing waste that doesn't involve Yucca? If a method could be found to greatly reduce the volume and threat of existing nuclear waste, wouldn't you be in favor of it?
Breeder-burners can use the spent fuel currently sitting idle in storage pools as well as weapons material that awaits decommissioning. I am against using Yucca for long-term storage but not for the same reasons as you I think. I think Yucca should be a short-term waystation to get the material out of storage pools until breeder-burners are online. My personal favorite is the IRF/AFR model.And there's tons of this stuff which is going to be criss-crossing the nation via rail, and truck, terrorist opportunities abound.
And how many accidents have there been? In France where the vast majority of the electricity comes from nuclear power, how many terrorist attacks have succeeded against the rail and trucks that have criss-crossed that nation for decades? What terrorist opportunities? Please enumerate them.
You mentioned hydroelectric. Look back at that energy map of California. What do you think would happen if terrorists attacked those dams, flooding the valleys in front of them, drowning the residents, and washing away homes, businesses, and communities? Or did you think hydroelectric was warm and fuzzy since you can't get thyroid cancer from it?Nuclear may be safe? But with a loose definition of safe.
Yes, it's a loose definition. That's what large-scale electricity generation entails. No form, not green, not nuclear, not fossil fuel-based is 100% safe when producing large amounts of energy on a municipal level.
And it will never be as safe as the green alternatives.
You're right. It's hard to be safer than an alternative that can't run at the same capacity. 104 nuclear facilities are licensed in the US -- many of them share a physical location. Only 102 of them are actually running. 20% of all US electricity comes from nuclear. How many nuclear accidents have occurred in US history? Now look at the number of injuries and fatalities both of workers and people in
