McCain Backs Nuclear Power 1563
bagsc writes "Senator John McCain set out another branch of his energy policy agenda today, with a key point: 45 new nuclear power plants by 2030." So it finally appears that this discussion is back on the table. I'm curious how Nevada feels about this, as well as the Obama campaign. All it took was $4/gallon gas I guess. When it hits $5, I figure one of the campaigns will start to promote Perpetual Motion.

Or with breeder reactors you basically have unlimited fuel. They're more complex to design perhaps but are certainly a solution to your claimed "problem".
Also - you probably read a few of the same articles i did about there not being enough fissile uranium around. The catch is it assumes a fixed (and rather low) cost as the ceiling. Once you increase that it becomes a non-issue even without breeder reactors. And before you compare tripling the price of uranium fuel to oil at $140 a barrel - the fuel cost for a nuclear plant is a rather small % of it's operating cost. It's not like they burn a trainload of uranium every few days like a coal plant.

The ignorance on nuclear reactors tends to irk me. I remember reading an Iron Man comic once, where Iron Man goes into the cooling tower, pulls out the reactor core, and throws it up into space, where it blows up in a nuclear explosion.
Problems being, as you noted the nuclear core is not in the cooling tower, and nuclear cores can't blow up like a nuclear bomb. Nuclear Physics 101. It just can't happen.
Fission bombs are set off by the rapid forming of a critical mass, either by joining two halves of a critical mass together in a millisecond's time, or, as with plutonium, by rapid implosion, usually of a sphere, causing the material to rapidly condense into a critical mass. (roughly described - I am not a nuclear physicist, so don't go all picky on the fine details everyone). It's an incredibly precise thing to get right. It doesn't just happen. Form the critical mass too slowly, and you create a whole lot of heat and radiation, but no boom.
I imagine that most of the fearful public does not understand this, even on a rudimentary level, and equates nuclear reactors with nuclear bombs. How many people think that Chernobyl was a nuclear explosion? Most I talk to. The no-nukes zealots commonly exploit this fear and ignorance. They are not interested in science, but in their ideology.

There's no technical or economic reason to ban reprocessing. Up to 92 percent of spent fuel can be re-used if reprocessed. Current law bans the practice. That's a political decision, made by the Carter Administration, because reprocessing spent fuel rods creates small amounts of Plutonium as a byproduct, and the argument was "but terrorists might get the Plutonium!". Well, they wouldn't if you secured the Plutonium. It's a silly argument. If that's the reason, then a President could solve the problem with a stroke of a pen; simply mandate that the military takes charge of the Plutonium and is responsible for guarding it. For those of you that have served in the military, you know how fanatical security forces are about the nuclear weapons in their charge. Recent USAF screwups aside, try and approach a nuclear weapons storage facility and see what happens to you. The security argument against reprocessing is simply farcical. France supplies nearly all of their power with Nuclear, and they reprocess their fuel to minimize waste. To date, Al Qaeda or Islamic Jihad doesn't seem to have been able to steal the French plutonium.
As for what to do with the remaining waste, just store it. There's several ways to do it. The easiest thing to do is simply store it in a secure facility. Do you know what highly technical mechanism is required to store spent fuel rods? A pool of water, 3 feet deep. France stores all their remaining nuclear waste in one single building, in a pool of water.
If you prefer to bury it, just encase the rods in glass, and bury it in a place where there's no water table. For the people going "Gasp! Radioactive materials! Underground!"... where do you think we got the uranium from the the first place? We dug it up. Underground.

Yes and no.
Plutonium is a small part of the waste. And is more radioactive than Uranium. But you can shield yourself from the radiation from plutonium by wrapping the plutonium in toilet paper - it's an alpha emitter. Note also that "more radioactive" than Uranium isn't really saying much - unless you eat the stuff, or otherwise metabolize something containing plutonium, it's pretty much harmless (IOW not very radioactive at all).
That said, most of the radioactive waste or a nuclear reactor isn't plutonium. It's a diverse mix of fission by-products and irradiated structural material. Half lives of "nuclear waste" vary from seconds to millenia, with the overwhelming majority being in the seconds part of that range. As an example, the nuclear power plants I worked on a few decades ago had radiation levels in the millions of REM per hour when operating. Shutdown, they dropped to less than 0.1 REM per hour within a day. And to trivial levels (less than a milli-REM per hour) after three days.
That's how quickly nuclear waste becomes inert. What's left after that point is the long half-life stuff. But "long half-life" is identical with "not very radioactive". So what goes into the holding tanks as "nuclear waste" isn't really much more radioactive than the average brick. And can be shielded quite effectively by the water in the tank (or your clothes).
Where you have problems with "nuclear waste" is when the (slightly) radioactive material is metabolized (mostly impossible - if you eat a chunk of plutonium, you'll shit it out unchanged in a day), or when it is chemically combined with something you CAN metabolize (not impossible, but difficult), or when you breathe the crap in (possible only when the radioactive waste has chemically combined with something that can produce airborne ash when burned). This last possibility isn't especially likely to be a problem, mostly because the stuff is much heavier than air - most of us don't keep our lungs around our ankles.
Note, by the way, that we've never had a person die of exposure to "nuclear waste". Not even at Chernobyl. And noone died at all, or was even exposed to much radioactivity, at TMI.
Re:Seriously, WTF? (Score:5, Interesting)
Yes. Natural uranium produces very little radiation. It isn't until it's enriched and undergoes fission that it gives off massive amounts of radiation. (Which is actually GOOD in this case, because we use those radioactive particles to heat the working fluid in the generators.)
After the uranium is burned via fission, a number of unstable isotopes remain. These isotopes will decay into other materials until they reach a stable state. This decay produces radiation of various types. Generally speaking, anything that's extremely "hot" will not remain so for very long. Since mass is being directly converted into energy, an isotope that gives off a lot of radiation will reach a less dangerous state faster than an isotope that gives off lower levels of radiation. This works to our advantage as contaminated areas can become safe for cleanup operations fairly quickly. (e.g. The wildlife in the Chernobyl area has already returned and adapted to the higher levels of radiation. In addition, the Chernobyl area is LESS radioactive than some areas of naturally occurring radiation where people are already present and thriving.)
As for what to do with the waste, the best solution is to burn it in a reactor. e.g. PU-239 is a natural by product of the U-238 that even highly enriched uranium contains. It's useful for implosion nuclear weapons (super-hard to construct), but it's also useful as a fuel to further power the nuclear plant. Once the fuels are no longer useful for power generation, they often become useful for a number of industrial, medical, and (*gasp!*) consumer applications. As a result, nearly all of the fuel can eventually be used.
Q: So why is there a problem with nuclear waste? A: Because politicians think that fuels like PU-239 are too dangerous because terrorists or foreign nationals might get hold of the materials and make an implosion bomb. (Did I mention that such bombs are incredibly hard to make?) As a result, they let the spent fuel rods sit in cooling pools where they pile up and become a disposal problem.
The odd part is that the government seems unconcerned that the Uranium fuel rods currently in use are very useful in creating a gun-type bomb. Gun-type bombs are easy to create. Any country with a strong enough industrial base could easily produce a gun-type weapon. Gun-type weapons are dangerous because the chances of the nuclear weapon going off by accident are fairly high in comparison to implosion bombs. But if your aim is to get the bomb by any means necessary, it doesn't seem like a big problem. Especially compared to the incredible amount of effort and testing that has to go into creating an implosion weapon.
Long story short: No, you can't put the materials back in the ground. Thankfully, there is no real reason to do so.

It is just more obvious because of McCain's age. Don't get me wrong, nuclear is currently the safest, greenest option that is economically viable, but promising things 20+ years into the future is pretty bad.

With the election of President Bill Clinton in 1992, and the appointment of Hazel O'Leary as the Secretary of Energy, there was pressure from the top to cancel the IFR. Sen. John Kerry (D, MA) and O'Leary led the opposition to the reactor, arguing that it would be a threat to non-proliferation efforts, and that it was a continuation of the Clinch River Breeder Reactor Project that had been canceled by Congress. Despite support for the reactor by then-Rep. Richard Durbin (D, IL) and U.S. Senators Carol Mosley Braun (D, IL) and Paul Simon (D, IL), funding for the reactor was slashed, and it was ultimately canceled in 1994. [Just 3 years before completion.]
Emphasis mine. See all those bold 'D's for Democrat? Uh huh.

Look, we (US) have enjoyed our luxury of cheap single source energy. Now it is time to get with the program. We need ALL options for energy started now. Think of it as a diversified portfolio. So, I say the following:
YES! Drill for more oil and make some more darn refineries
YES! Build some nuclear power plants.
YES! Explore better ways to use coal in existing power plants.
YES! Build huge solar arrays and start larger solar power plants
YES! Build wave generated power plants
YES! Build wind generated power plants
YES! Build electric-based "commuter" vehicles
YES! Explore better ways to make bio-fuel
The government needs to subsidize some of the projects and needs to throw some money at these problems. If we deploy all of these strategies we may not get cheaper energy but we will get stable energy and maybe, just maybe avert major crisis as population and demand increases exponentially over the next 10 years.

Japan holds keys to nuclear plant construction (Score:5, Informative)
There was an article covered a while back (http://hardware.slashdot.org/article.pl?sid=08/03/14/1238233 [slashdot.org]) talking about the 600-ton steel forgings required for a reactor containment vessel and the fact that on one company in Japan can, currently, make them. Given that their production rate is only 5 per year and their first open slot is in ~2015, the US would need 80% of their output from 2015 to 2027 to hope to meet that goal.
Unless the rest of the world stops building nuclear plants or someone else starts making containment vessels, all this is just talk.

Um no. Regulations is exactly why we are in this problem. In the US the red tape that you have to cut through to drill new wells or even just to refine oil prevents many companies from opening new wells and refineries. In the rest of the world (Chindia, Mexico, etc...), the socialist policies that have capped and subsidized gas prices have led to the continued high demand even while prices surged. In a normal market economy demand would have already slowed (as it has in the US) and prices would have come down. I'm expecting demand in China to finally slow when they start removing gas subsidies after the olympics.
Re:Obama better support this too (Score:4, Informative)
Means the same thing really; McCain pushed so-called "clean coal" at the same time as he pushed Nuclear, [washingtonpost.com] which is a bit more Republican of him, since coal states are red states, and big electric has no desire to stop building coal plants.
Nuclear is the best of a lot of bad options, and regardless of presidents, the return to nuclear power has already begun, as witnessed by the resurge in permit applications since last year. [msn.com]

...and the other two points. Sure, those are true but they didn't just magically happen either. It wasn't just because these countries are 'small' - much as Americans are so very fond of thinking of Europe (while they themselves tend to move very small distances from where they were born, as a statistic) - it's because the governments of Europe imposed tax penalties on fuel.
This was done to hit demand and create a market for fuel efficient vehicles and other practises that curb demand. It's worked too, oil burned per capita of people in Europe is a fraction of what Americans use and the CO2 output per capita is even more stark.
America retained the love of huge fuel inefficient cars, SUVs etc while the lobby-driven politics ensured it was political suicide for anyone to grow a spin and impose fuel taxation or indeed any other significant measures to break the American love affair with burning oil.
Most cars people drive in Europe are smaller, designed primarily for running costs and not the sound that a large capacity engine makes (you've got to listen to the round-tabel panel on Ward's Top Ten engines for a clue as to just how important they believe this junk to be), but instead the engines are more expensive and technically advanced to improve economy.
So baring this in mind, it's pretty unfair to suggest that Europe just got handed all of these advantages. They were hard fought and hard won. We've been paying decades of tax on fuel.
While you're whining about $4 a gallon, we're paying $5 a gallon JUST IN TAX. We're already driving around fuel efficient vehicles and paying through the nose with road/green taxes, CO2-based taxes, expensive emissions standards driving up costs of vehicles and servicing costs and have been for YEARS. So you'll have to excuse us if we don't have vast amounts of sympathy for the complaints coming from the other side of the Atlantic right now.
