Alot of groups want to shut down Nuclear powerplants. I don't see why. It's the safest (yes) most efficient way of producing power we have. The only real accident that has occured (to my knowledge) is chernobyl, and that only happened because they used granite instead of water for the cool down process. Which is stupid, granite can catch fire.

Despite groups wanting to shut it down they never put up a proposal of alternative power income. They might throw out windplants or waterplants as an arguement but that isn't really a smart alternative.

Windplants; You need big plains and wind for them to do any good. And not to mention; a shitload of them.

Waterplants; A nice and effective way of destroying waterlife. Here in Sweden we've put a waterplant on almost every possible lake. Only 2 left and those are preserved.

Coal; You're kidding right?

Lets just live in a permanent blackout maybe?

One arguement against Nuclear PowerPlants might be that the waste is dangerous and the toxic level will stay the same for thousands of years. Solution? Bury it. There's been several attempts/proposals to bury the toxic waste miles under the sealevel. And it won't just be dirt against waste, it'll be sealed in 'caskets' that will let nil out.

So, what ain't I seeing here? Or is just many tree-hugging groups misinformed or crazy?

honestly... the best solution to date for power issues (in some places) solar power!

now, that's not a complete solution, since a lot of places are covered by clouds a lot of the time.... but hook solar panels to roofs of houses all over the place... and you'll cut down significantly on the amount of power used.... and your electricity bill ....

it's not a complete solution, but it definately falls into the wind power and water power category of being better than some of the alternatives....

as for Nuclear.... I'm all for it.... chernobyl blew up during a test of something.... can't remember what, but it shouldn't have happened....

anyways.... I don't see it as dangerous, especially now with the much more advanced technology we have covering nearly every aspect of nuclear power.

the only drawback is the waste.... which would have to be dealt with.... and that's not an easy thing to deal with.... although, find a desert.... that no one goes into (Sahara! ) and dump it there.... that way no one sees it, or feels it's effects

Granite can catch fire? Granite is quartz, a mica of some kind, and one of the three feldspars...none of these are flammable. Granite, though, doesn't transmit heat well for anything...there's the trouble.

As to nuclear power...fision reactors are disgustingly inefficient. Power output opposed to actual energy released...it's something like 10%, to 25% in the best case scenario. Coal tends to give about 40%...though almost all of the good coal worldwide is spent. Solar panels aren't too good either...we gotta work on these....

Now, if we can get fusion to the point that we're getting more energy out than what it takes to get it started, we'll be in good shape. Hydrogen's everywhere. The bi-product: helium. That'll just rise high into the atmosphere, where it doesn't interact with people. Could make the atmosphere & light coming in a bit odd after awhile...that part is uncertain.

As to getting spent control rods, here's my suggestion: drop 'em down a trench; it's a subduction zone anyway, it'll get pushed into the mantle, and the chances of it coming back to the surface via an andesitic volcano ('cuz if it gets back to the surface relatively quickly, that's how it'll happen) before it's safe is pretty damn low. Many even get some interesting minerals (and thus, rocks) many thousands of years from now because of it. Trouble of this is whether or not it's economical.

the only problem with fusion is we can't control it like fission.... at least, not that I know of....

there is always the theoretical cold fusion.... but, the big problem being "theoretical"....

it is true though... if we could actually do fusion.... we would never run out of power.... life would be pretty damn sweet....

I can't remember what movie it was, but it said something like a square meter of sea water would run the world for like 50 years... something silly like that....

Solar plants wouldn't work in Sweden becuse of our climate, but well. I could see it working down in Sahara. Hell there is talk about Hydrogen cars, and that Hydrogen should be produced with the help of solar plants.

If we could convert 100% of the light to power, then Solar plants would be the best thing ever.

I just remembered neotransotaku's "solar-power flashlight" comment when I read geeo's post. XD

Hm... All sources of power have their flaws. Solar and wind aren't constant (cloudy days, no wind sometimes...), coal has an assload of pollution, nuclear has (although rare) meltdowns...

If we could go by hydroelectric, solar, and wind power, that'd be great. But we can't. Places like Sweden don't get enough sunlight for solar (because of the angle the sun's rays hit), wind's unreliable in most places I can think of, and not every place can build a dam.


Granite catching fire, eh? That should be interesting... Screw the brick through the window, throw a flaming rock!

Well, Nuclear is clean, and it provides a lot of power. On the other hand, IF something happens, it's nothing much we can do. Here in Norway, we don't have nuclear power plants, most of the power generated comes from waterfalls and such. I think nuclear plants is ok in the developed world, since we follow the safety rules. And Russia's nuclear plants is actually one of the biggest threats that can affect Norway and Europe today. When Tsjernobyl exploded, many people went affected even here...

But I think nuclear is still better than coal and such. However, I think only Solar, Wind and Waterfall-generated should provide power. But that would be impossible...

Uh, about the granite thing, I'm sure there was something with fire. Maybe I just interpeted it wrong when I heard it, maybe it wasn't granite but something else. I'm sure something catched fire though XD

Kiwi; I saw one of those at the Nuclear Plant near my hometown, it's reaaally small, and it's not radioactive before it's gone through any process. You could like pick it up and hold it between your indexfinger and thumb.

Yeah, If a Nuclear plant goes down it affects many, but don't people think it affects just as many if not more if we just buy electricity from another country that just happens to use coal? It's the same world.

Some homeowners here have small solarplates on their rooftops or next to the houses but the dumb thing is that it only gives enough power to maybe heat your .. heaters. Guess when it gives most power? Yeah, summer. Guess when you need your heaters most? Yeah, winter. Very useful. And as we all know, energy can't be stored. It's fresh.

Has there been any other meltdowns except Chernobyl?

Oh yeah, the walls on a reactor can withstand a direct planecrash.

Yes of course. Three mile island anyone?

Althought Chernobyl have been the most disastorus one. Due to poor safety, the other Nuclear plants hadn't released that much when having meltdown...

Bah, partial core meltdown.
"No identifiable injuries due to radiation occurred (although a government report by L. Battist et. al. stated that "the projected number of excess fatal cancers due to the accident ... is approximately one.")"

That's nothing. Bet more people die from flying into windplants or drowning in a waterplant. Or chopping off their own heads in search for timber for fuel.

Well, Three mile island is the most well known accident apart from Chernobyl, probably becuse it's in USA and all but...

And yeah, besides that accident happened before Nuclear power was "OMG dangerous". Now the security is much higher. And all... and hell there is a type of reactor now that is effective, cheap and secure now. Where an meltdown is suppodsdly impossible.

The Soviets used a graphite silica compound designed to melt and encase radioactive isotopes inorder to slow the reaching of critical mass. The additional problem with Chernoybl was that the engineers at the plant were running stress and safety tests without the proper safeties. The reason it happened was the 10 ton reactor cap blew off because of a steam and pressure build up. And that 10 ton reactor top was a granite slab. The steam threw it away like a frisbee. In fact, that steam vent had the same equivelent force of the Hiroshima explosion.

There are three major reactors, the new Chinese one, the American hybrid and the CANDU from you guessed it, Canada. The American hybrid reactor puts out 1.233354323424546756432% more than the Canadian one or a relatively miniscule amount. The Canadian CANDU reactor is nay impossible to melt-down, unfortunately the reactor isn't a really completed project. It has the capability for more and on going research will insure it is a good investment for power hungry nations. The Chinese reactor is as small as a large pick up truck and produces half as much energy as either the Canadian or American reactor. They also use less fuel and CANNOT melt down. I could dip myself into the water and let it go, and I wouldn't cause a melt down.

I like nuclear power. It isn't all that dangerous, it provides a lot of energy, and it is better than most other alternate methods. The only place solar panels and wind turbines would work is on a giant platue or something. Kansas would do fine with them, but I'd prefer a reliable new nuke plant. I wouldn't mind being able to use hydrogen though, that sounds interesting. Now we only have to find a way to make anti matter and all that Star Trek stuff.

It's already possible to make anti-matter, but it's so expensive to make and takes so much energy... it's not worth it.

And scientists hadn't seen any natural occurance of Anti-matter in space, just in labs.

But yeah, if we found tons of anti-matter then we could produce energy that makes the world going around for years. But how would you contain something that destroys any normal matter? ;P

I'm leaning towards thoose safe reactors Ziff is mentioning, hell I wouldn't mind a closedown of our reactors IF they built new ones who are safer and more effective.

...hell the biggest problem with Nuclear is it's waste, not that they meltdown.

You know that less than 100gram of anti-matter has the power of a H-bomb, right?

If it reacts with matter.

Anti-matter exists on Earth, but it is kept in near absolute zero so that it cannot react with matter. Unfortunately, it is in such trace amounts that our knowledge of how it would react to exposition to a large amount of matter...Well theoretical physics is just that...Theoretical.

The future is in renewable and sustainable power. It takes a lot more space, but if done properly it can be quite rewarding.

Nuclear waste can be re-used, it's just the byproduct of that re-use just happens to be weapons-grade, so it's banned, at least here, anyway.
