Environmentalists Coming Around to Nuclear Power?
Heywood J. Blaume writes "In a Washington Post editorial Patrick Moore, a founder of Greenpeace, now says he was wrong about opposing nuclear power 30 years ago. In the article he addresses common myths about nuclear power, and puts forth the position that nuclear power is the only feasible, affordable power source that can solve today's growing environmental and energy policy issues. From the article: 'Thirty years on, my views have changed, and the rest of the environmental movement needs to update its views, too, because nuclear energy may just be the energy source that can save our planet from another possible disaster: catastrophic climate change.'"
This isn't a new thing, as the article (summary) implies. Moore has had this stance for a while now. Here's a 2004 Wired article on this "Eco-Traitor."

I'd be more impressed if Moore would admit that he's now serving as a consultant for the mining, logging, and energy industries.
Hell, I'd settle for the Washington Post admitting that they're trying to pull one over its readership.

pebble bed reactors make all the difference
because they are super safe. they don't melt down. no china syndrome, no 3 mile island, no chernobyl, no silkwood. the fuel is packed in glass pebbles. meltdown is not possible by accidental means
explain this to people and their old understanding of nuclear's dangers, based on 1970s era thinking fade away. which is also about the time that nuclear itself faded away, because of the dangers. but in a world of oil-funded islamic extremism and oil-fueled global warming, super-safe pebble bed nuclear energy looks mighty attractive. now all we need to do is wait for popular wisdom and political will to catch up
and with breeder reactors, we can reprocess the nuclear waste from the bygone era of old-style reactors and do away with all of that left-over pollution. imagine that: run new reactors off of a previous generation's waste. old-style reactors only use 10% of available fuel, the rest sits unused and radiocative for tens of thousands of years. with reprocessing, 95% of the fuel can be used, and left over are isotopes with radioactive half lives measured in a century or two, not tens of thousands of years
and don't let anyone tell you there would be a fuel shortage with the nuclear option like with oil. there is no peak uranium like there is peak oil. mainly because we can run nuclear power off of thorium as well as uranium. go look up the numbers on thorium reserves. we'd be fine for centuries. and the reserves are in more geopolitically friendly places
the problem is still psychological for people though. nuclear IS scary. it's the same thing as flying: it's safer than driving, but people prefer to drive than fly, and feel safer driving than flying. even though the reverse is true. why? the illusion of familiarity and control. people stick with what they are comfortable with, even if what they are comfortable with sucks in comparison
for the longest time i've tried to convince my gf to have laser eye treatment for her myopia. it's the best thing i ever did. but she is scared of the procedure. i tell her that she has more chance of getting an infection that will make her blind via contacts than via a laser screw up. but she wouldn't have any of it
and just this month, they found a connection between bausch and lomb's renu, which she uses, and a sudden surge in cases of an eye fungus that blinds people. sure enough, on her very own, she made inquiries as to laser eye treatment last week
so even though nuclear is safer in this world than oil due to hurricane katrina-making global warming and oil-funded 9/11 terrorism, people are more scared of nuclear than oil. they are familiar with oil, and there is an inertia about their reluctance to embrace nuclear
so we're stuck in the inertia now, and we suffer for the inertia of the general public and the politicians. all of the nimby's who wouldn't let these things be built would apparently prefer to ship their children to falluja to protect oil than build a completely safe pebble bed reactor. meanwhile, china is investing heavily in this technology. so while the usa wears itself down fighting islamonazi wackjobs sitting on top of their precious oil, places like china will enjoy air pollution free totally safe pebble bed reactor power
some morons don't understand the science, but know how to yell loudly and chain themselves to train tracks to prevent uranium shipments
and we all suffer for that
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
Ah, the old scientists in the 1970s believed in global cooling myth rears its ugly head again.

Wikipedia: Nuclear Power
I am not a nuclear physicist, so it could be full of crap, but wiki's science info is generally pretty sound.
Energy shortage is no more a disaster than most other shortages, provided you have an economy based on supply and demand.
Look at water. Many people have claimed that there would be water shortages in the California. Everyone should conserve water because we're running out. Now look in the Middle East. People have no problem paying for desalination plants. But you never hear them talk about water conservation in the Mid East, because who on Earth would waste such an expensive resource as water? California would find it has plenty of water if people have to pay what water is worth.
The reason we face energy shortages has nothing to do with the fact that we're running out. It has to do with the fact that we waste it. When the price gets high enough, provided of course that the government lets it get high, then you'll find out people get quite resourceful about conservation. You'll also find that there is plenty of energy to do the things we must.

Does it bother you that hurricane researchers have said repeatedly that global warming had little or nothing to do with it, and that there was an expected upswell of activity due starting last year, give or take? Or that the US coastline had been dodging the averages for the better part of 20 years, with a far smaller fraction of hurricane strikes than the historic record would otherwise suggest? What will you be saying if the next hurricane season shows lower activity than the last?
You can never go home again... but I guess you can shop there.
That 48 tons of waste per plant per year could be greatly reduced with spent fuel reprocessing. Most other nuclear nations, including the UK and France, go this route, which is a lot more sensible than just burying everything, however due to some really boneheaded decisions made by President Carter, it's never been done recently in the United States.
Until it was banned, we had a whole system under construction for reprocessing spent fuel that would have reduced the scope of the problem we're now faced with. However, in 1977 the research was cut off, and further development and implementation was banned; although President Reagan quietly reversed the ban, nobody has been willing to put money into it. Except of course the military, their ability to manufacture plutonium for weapons purposes was never affected, something which strikes me as endlessly ironic, given that Carter's justification for banning reprocessing was ostensibly to prevent the spread of nuclear weapons.
By processing the spent fuel assemblies promptly (before they sit around and create a lot of secondary contamination) you reduce the volume of waste that has to be stored for long periods, and you also get a non-trivial amount of new fuel back (even out of reactors that aren't specifically designed to breed new fuel). Either one of those goals would make the procedure worthwhile in my opinion, pick your favorite and count the other one as a bonus. Right now we're burying tons of waste which isn't itself that radioactive or long-lived or even toxic, but because it's physically joined to stuff that is. The actual volume of long-lived high-level waste produced by a plant isn't that much, if you do the right reprocessing first.
The plan in the United States was a process called PUREX; you can Google it for more information. The French do their reprocessing at COGMA LaHague, and the Brits do it at a commercial facility called THORP.

The argument, IIRC, is centred on the intensity of hurricanes. Activity based on numbers of hurricanes do not capture such an effect, while intensity graphs show a pretty good correlation. Though things are still sketchy at the moment, you can't make a handwave motion and suggest that all hurricane researchers are of the same opinion.
Almost all climate scientists accept anthropogenic-caused global warming.
The Spanish-English dictionary is out of ink.
If we'd just get them going, Department of Energy laboratories could pretty much eliminate the problem, but anytime someone proposes doing that, who do you think blocks it? But then, if you let them create a way to eliminate the waste, you couldn't block nuclear plants by complaining there's nothing to do with the waste.
Disclaimer: I own stock in the world's largest uranium mining company.
It has been stated that the world will run out of uranium in 50 years, or variations thereof. The problem with this statement is you have to ignore a lot of facts to come up with it. This statement assumes that the uranium deposits currently being mined are all that there is. The fact is, we're currently sitting on at least 50 years worth, and there is no real reason to start mining new deposits at this time. As these deposits get depleted, and as (if) the market price of uranium rises, more exploration will be done, and more deposits will be mined. If the price rises high enough, it becomes feasable to "mine" the uranium dissolved in the oceans. If it rises even higher, it becomes feasable to produce it in breeder reactors. In short, the world is _not_ running out of uranium. Second, the "50 year" statement assumes that we will not improve our reactor technology. In north america, we're still running 30+ year old reactors that only remove 5% of the available energy in the uranium. The "waste" that comes out of these reactors can be processed and put through again, or can be used in newer designs to extract more energy from the same uranium. So, ignoring the idea of finding new reserves to mine, if we improve our efficiency to even 50%, we'll now have 500 years worth. (of course, now _I'm_ ignoring the inevitable fact that we will consume more than our current rate over the next 500 years.)
Time for you to learn something new.

"The only solution on the table right now is Yucca"
Well, there's always the reprocessing route. If you use a breeder reactor and waste reprocessing fuel cycle, you can eliminate all of the high level, won't go away for thousands of years waste. Of course, you still have the "low level" waste, but that will go away after a few hundred years (maybe 500 or so to be safe). The great part is that they've figured out how to convert conventional PWR's and BWR's into breeders through advanced computer modeling, so there's no need for any new R&D. The only problem is that it's a lot more expensive than the once through fuel cycle. I guess you can have it clean, or you can have it cheap. Its cheaper and cleaner than coal anyway.
Storing the high level waste isn't really as much as a problem as you think, either. 48 tons of nuclear waste may sound like a lot, but it's really only a few cubic meters. There are salt domes in new mexico that will probably be geologically stable for millions of years (look up the waste isolation pilot plant, WIPP). The only reason yucca mountain is at yucca mountain is politics, it's really a pretty bad location. At any rate, 48 tons of waste per year compares favorably to the hundreds of tones of waste generated daily by a coal plant, in my opinion.
