Yet folks want to piss and moan about not building new refineries.
The waste from nuclear isn't that bad. It's usually solid, so just store it somewhere safe, like the Yucca Mt. Plan. It's not like it's going to explode, seep into ground water or anything else for that matter.
Eventually, we will have the technology to minimize even this, what I consider, small problem.
Yes it will eventually start to seep into the ground water.. and NO it is not a small problem
The problem with radioactivity is that it is nearly-eternal. A radioactive substance will remain radioactive for a VERY long time, millenia in some cases. You can't spread it around. There is enough radioactive waste today that if you spread it EVENLY on the whole surface of the globe, the entire place would be a wasteland. It is THAT bad. The idea would be to spread this waste evenly in the whole VOLUME of the earth. Now the guy who invents the technology to do that isn't born yet.
Send it to the moon, I tells ya! God already gave us a nuclear waste dump. Yeah, it's going to mess up some love songs, but it's time we put the moon to some use.Originally Posted by Matthew D

Plus the technology to minimize even this small problem is at most 25 years away. The research reactor I worked at is/was working on this problem themselves and had developed a way to separate the and reuse the radioactive part of spent fuel rods. You can store this stuff safely and effectively.
It depends on what isotope you're talking about. Some are only radioactive for a few hours, some hundreds of thousands of years. There is a wide range of half-lives among isotopes. The ones that last a long time are usually the safest to store due to what type of radioactive energy is being released(alpha, beta, gamma, x-ray, etc.) Most of the stuff that lasts a long time are alpha-emitters, which means that a piece of paper or your skin can block the radioactivity. You just don't want to get the stuff in your system, where it can do some major damage. Now if you had gamma or x-ray emitters, then there would be some issues, but this isn't the case. Even then, stored under a mountain, away from people, it would be perfectly safe. Some you need to stop looking at "The China Syndrome" for your knowledge on this subject and start looking at from a real fact perspective.Originally Posted by ss01
I don't know how many times I have hear absolutes turn into... well we didn't think it could happen.. AND No I don't base my information from a damn movie.. I do remember hearing when I was a kid that asbestoes was the next best thing to sliced bread and other BS.. alpha-emitting particles do have the ability to mutate DNA and that my friend is a very serious thing.. Someone refresh my memory why did we abandon more than a few nuclear reactor construction sites?
25 years away on dealing with a waste problem.. umm.. I will have to see that to believe that one, not that I think you are lying but I know how that things we thought were coming down the pipe suddenly didn't materialize in the time frame we thought they would.
I know it is stored under a mountain in a area that has not be seismically active for as long as we have been recording but the whole thought of all that waste stored in one area gives me the willies...
I personally wish that Oak Ridge would be able to solve their problems with fusion reactors and then I wouldn't mind nuke power as much..

That takes a lot millirem to achieve that, plus it would have to be beta, gamma or x-ray emitters or godforbid a neutron emitter(which if that happened, mutation would be the least of your worries.) Like I said in my earlier post, at the research reactor I worked at, they have achieved separating the radioactive part of a spent fuel rod(5% of the rod) from the the rest(95% inert material) and can reuse it. That cuts down tremendously on the waste.
As far as why reactors have been abandoned? Well, because the laws and regulations are so ridiculous when it comes to reactors, they became economically not feasible. Treat it like other industries with sane and logical regs, they would have been completed.
...and when someone flies a jet into an active reactor?
The reactor I worked at can take a direct hit by a 747 and still be intact. You do realize the kind of containment built around these things don't you? 6 to 18 ft of reinforced concrete, 1 to 2 ft of steel, another couple of feet of lead, just to name a few. The outer building(s) will be toast, but the reactor itself will be just fine.
2.67 for regular here last I checked.Originally Posted by jmh80
When I saw how much shielding the newer generation of reactors had, I wasn't worried about terrorists. Tracking waste might still be an issue, the reactors aren't.Originally Posted by Sir Foxx
I'll bet that when the exterior buildings of the reactor are all smashed to bits and the inside of the reactor gets shaken HARD by a thousand-ton object flying into it at hundreds of miles an hour, that some part of the management system fails, and the whole thing goes meltdown.
That's the worrisome part. Oh, and if the 9/11 attacks really wanted to REALLY rattle america, they would have tried something like that.
I would doubt it from what I've seen. The things are built like small mountains with Christ knows how many safeties. Plus, there's always risk vs reward. If there's a major chance it could help reduce dependence on petroleum products and a very minor chance a few hundred to a few thousand people might get irradiated, I say build them. Stick one right in the middle of my neighborhood if they want, I'm game.Originally Posted by ss01
Amazing, what $2.69 a gallon gas can buy, isn't it?
In case you're wondering where this hotel is, it isn't a hotel at all. It is a house!
It's owned by the family of Sheikh Zayed bin Sultan Al Nahyan, the former president of theUnited Arab Emirates and ruler of Abu-Dhabi. Wonder what the CEO of Exxon/Mobil house looks like??
more pics of the house - check out the bentleys
hahahaha-that's crazy!!! Ill do whatever I can to decrease my dependance on petroleum products. First step was getting rid of my truck and buying an Accord. Next summer maybe Ill run all my errands on a motorcycle.
The US is pretty behind and finally now understands what other countries have done for years and years. We want our conveniences and at all costs and when things get harder, we bitch. You all know how it goes... gotta have those cabins and weekend trips hours away, or gotta pull those boats with a truck, or have that room, etc, etc.
Bah, I just bought an SUV a few months ago... but my wife and I carpool to work now and save TONS of money. It's too bad we didn't wake up sooner and demand different cars running on different energy sources. It's also too bad we don't use public transportation nor put the money we should into developing it.
And yeah, I can say that and I'm just as bad as everybody else... but getting better.
