The Nuclear Power Renaissance

Actual Reality writes "It is ironic to me that much of the same sentiment that thwarted the nuclear power industry back in the 80's is partially responsible for reviving it. Nuclear power is very clean compared to any power source that burns fuel. The US has missed several advancements in nuclear technology. We can only hope that environmental concerns will not again stifle our progress."

    No, nuclear isn't perfect.  But in combination with electric cars, the CO2 problem is solved.

      The CIA world fact book says 2004 electrical production (not counting transportation energy, etc) was 17.4 trillion kW-hours, so we'd need at least 2 TerraWatts of capacity. A relatively large nuclear reactor produces about a GW of electricity, which translates to 2000 plants. Add in other energy needs currently met by fossil fuels and account for capacity factors and that CalTech professor you reference is probably within an order of magnitude of the actual need.

      The problem with that argument is it only demonstrates the scope of our energy needs. It says nothing about the feasibility of nuclear versus other technologies, and ignores the fact that the exact same challenge applies to any energy source. To cover our needs with just coal (currently 25% of the world energy supply and something like half of the electrical supply) would similarly require about 10,000 coal plants. You want to it with wind? You need roughly one million of today's highest capacity wind turbines. Solar? About $20 trillion dollars worth of solar panels near the equator will do it. Hydro? Well...forget about that one. Hydro power options are mostly in use in developed countries.

      We'd run out of nuclear fuel in decades (actually, I've been told centuries) if we continued to utilize it as poorly as we currently do. Reprocessing, however, can dramatically increase the available energy from existing fuel and potentially the economics of developing new mines. Not to mention reducing the waste by 90% or so.

      Don't forget we're just talking about nuclear fission here. If we can get fusion working commercially, the picture changes.

      Anyone who thinks we'll get all our energy from one source in the foreseeable future, however, is out of the loop.

When the government privatised the nuclear power stations they had to finally admit what had until then been denied - that it was the most expensive form of generation then in widespread use.

In fact, France has so much cheap electricity, it exports it to its European neighbors. French nuclear plants supply power to parts of Germany, Italy and help light the city of London.

Such waste is more hazardous, but its disposal is less challenging because the necessary term of safe storage is greatly reduced.

    While I agree it's interesting that *some* environmentalists are rallying around Nuclear power, I think we need to make a few things clear that the poster of this news article seems to have missed.

    1) Most environmentalists supporting the Nuclear option do so only because it is the lesser of two evils, the latter of which (Global Warming) was not known of or understood back when the Nuclear Power protests were going on. This isn't ironic, it's evolutionary. It's the scientific process at its finest: new data comes in, and those looking out for the best interests of everyone reevaluate their previous conclusions based on that new data. The two are NOT mutually exclusive.

    2) The "We can only hope that environmental concerns will not again, stifle our progress," is a bit more blatent of an example of flamebaiting. The reason that environmental concerns occasionally "stifle our progress" is because it would be foolish for anyone NOT to think of environmental concerns. Would the poster of this article rather that environmental concerns never be taken into account in the case of new technology? It would be like a scientist intentionally ignoring a key variable in a study. You wouldn't tell a clinical group performing studies on a new (for example) vaccine to ignore if the vaccine causes heart attacks just because said vaccine is supposed to cure cancer.

There are responsible ways to use hydro and wind power. Geothermal power is also worth exploring. But none of those can provide the power that we need.

    And here's where I fit your caraciture: I do oppose raising energy rates and reducing consuption because it's anti-progressive, or as I prefer to say, regressive. Any extra burdens imposed on the cost of energy are going to disproportionately hurt the poor, and they've had it bad enough. Besides, it's totally unrealistic. Of course we should be doing more to insulate houses, and I strongly support government subsidies for doing that. But in a choice between reducing energy use and not reducing it while taking the risk of global climate catastrophe, Americans (maybe people in general) will choose the latter ten out of ten times. We can get mad about it or we can get realistic about it and provide them with the one clean source of power that we know how to develop on a large scale. Sucks that we'll probably have to bring in French engineers to do it right; we've really lost our technological lead in this industry!

    Regarding the spent fuel, there is an obvious answer: Reprocessing. The most radioactive stuff that we bury now are the heavy metals which are actually fissile and could be used to produce more energy. The rest of the waste, if processed correctly, would be less radioactive in 30 years than the ore that was originally mined. So in the long run we'd be reducing the amount of radioactive stuff in the ground.

All other sources of non-emitting power cost about ~3x as much per kilowatt. According to the DOE (http://www.eia.doe.gov/cneaf/electricity/page/co2_report/co2emiss.pdf) 40% of all CO2 generated in America is produced from electricity generation.

    The stupid, stupid environmental prejudice against nuclear power has come back to bite us all on the ass. If we had all nuclear power plants now instead of majority coal plants, we'd have eliminated almost half the CO2 production from our country which is MUCH MUCH more than reductions mandated by agreements like the Kyoto protocols, which specify either minimal cuts (8% for Europe) or capping increases (Australia can go up by 8%).

    Nuclear power is very clean compared to any power source that burns fuel. If you are going to toss around inexact language like "is very clean" I don't think you can afford to be picky about what it means to "burn fuel".

We have to evolve means of obtaining energy from stores which are forever inexhaustible, to perfect methods which do not imply consumption and waste of any material whatever. If we use fuel to get our power, we are living on our capital and exhausting it rapidly. This method is barbarous and wantonly wasteful and will have to be stopped in the interest of coming generations."

    If it uses up a limited resource, it's "burning fuel", at least metaphorically, and therefore lame. Screw that. Let's figure out how to tap into the vast power represented by the titanic spinning mass we live on, or the even more titanic mass that shines in our skies, instead of perpetuating the cycle of digging stuff up stuff until it we use it all up.

    You gotta be kidding me. We don't use nuclear because it would hurt the oil industry? First off, there's a difference between oil, which runs our cars, and coal, which runs our power plants, which you don't seem to grasp. Second and more importantly, the real reason we don't have much nuclear power in the US is because for decades "environmentalists" have been waging a misguided war against nuclear power. These activists eroded public support for nuclear energy, and their lobbyists got our politicians to impose such stringent roadblocks and regulations that it became impossible for any company to even think about building in a new nuclear power plant in the US. Thanks to their ignorance and short-sightedness, these activists contributed in a major way to the problem of global warming, which they now say will be the doom of us all. And what makes it even more ironic is that the activists are still at it today. Sure nuclear is not perfect. But the safety issue was settled long ago. So the only downside is waste disposal, and the technology to process nuclear waste is advancing rapidly. And anyway, the stuff comes out of the ground, so we just have to put it back there, and make sure it stays there. All this talk about nuclear waste being a terrible hazard and environmental concern for the "next 10,000 years" is ridiculous. Some time in the next 500 years we'll figure out an even better way to handle, or use, nuclear waste, and it'll become a null issue (unless global warming kills us all by then of course).

  11. Molten Salt Reactors by mosb1000 · · Score: 5, Interesting

    Reprocessing is expensive mainly due to the labor involved in reprocessing it. Spent fuel must be cut apart and chemically treated in a clean room environment. Removing the tans-uranic elements from spent fuel is not complicated from a chemistry standpoint, but handling spent nuclear fuel is always expensive.

    One potential solution is molten salt reactors, which do not use fuel elements but rather use molten uranium salts. Since there are no fuel elements, fuel from the reactor can be chemically treated without a lot of handling. It may even be possible to continuously process the fuel while it's still in the reactor (though this has never been done). Doing this could completely solve the problem of long-term nuclear waste. The only waste produced by such a reactor would be depleted uranium and fission products. Of course, the fission products would need to be safely stored for 300 years before they were safe, but that's a lot better than the trans-uranics that we have to deal with now.

    Molten salt reactors also have advantages when it comes to fail safe design. Since they don't have fuel elements or control rods, there is nothing in the reactor core which can break or wear out and cause a melt down to occur. In the case of emergencies, the reactor can be drained into sub-critical containment vessels.
