Planned Nuclear Reactors Will Destroy Atomic Waste

separsons writes "A group of French scientists are developing a nuclear reactor that burns up actinides — highly radioactive uranium isotopes. They estimate that 'the volume of high-level nuclear waste produced by all of France’s 58 reactors over the past 40 years could fit in one Olympic-size swimming pool.' And they're not the only ones trying to eliminate atomic waste: Researchers at the University of Texas in Austin are working on a fusion-fission reactor. The reactor destroys waste by firing streams of neutrons at it, reducing atomic waste by up to 99 percent!"

What they found out was that for deaths due to normal operations, radiation exposure, etc, ordinary citizens were actually MORE optimistic than the experts, and although the ordinary citizens predicted much more drastic fallout from a nuclear disaster, even after they were informed of the right answer, they still didn't change their opinions. The second study was one where they took college educated citizens, got their opinions on nuclear power and gave them a quiz to test for knowledge on nuclear power, and then gave them a few weeks of classes about nuclear power. Even though at the end of the courses the citizens scored very well on a similar quiz about nuclear power, their opinions on nuclear power essentially hadn't changed.

      Take a look at the http://en.wikipedia.org/wiki/Solar_updraft_tower .

      The numbers I read suggest that each square kilometer could produce several megawatts (up to 10, depending on conditions), comparable to a large traditional plant. You still need a lot of land, but there are a lot of places where land is cheap. Also, the space under the collector need not go to waste - grow crops there instead. It is literally a (windy) greenhouse, and moist air actually increases collection efficiency.

      Such plants could simultaneously produce massive amounts of food and power. The required moisture in the air tends to be lacking in the desert, but they end up reclaiming that moisture each nightfall (although obviously the crops absorb some of it, so you do need to continuously provide more). The energy density certainly isn't terribly impressive, but there's a *lot* of terrain that could be used for things like this. For that matter, you actually could encase existing farmland, if you wanted - it might even increase production.

      From what I read, the problem is building the cooling/exhaust towers. They need to be tall and wide enough to hold the majority of the air that rushes through the generators each day, otherwise you both lose efficiency (the energy of the moisture-heavy air rushing back down the tower at nightfall can provide lots of power) and water retention. The altitude to which the tower needs to be built depends on local atmospheric conditions - how fast air cools as it rises, and how hot the air will be at the base of the tower - which leads to such slightly awkward numbers as Namibia's proposed 1500m (very nearly a mile) towers.

Humans made do without profligate energy spending for thousands of years. We can do it again. Once high EROEI energy runs out, we will certainly learn to make do again. With the engineering knowledge we have now, a future society living with a frugal energy budget would look much more similar to our own than say, life in the 1700s, or even life in the early 1900s. We have the internet to transmit that information, and the engineering knowledge exists now to make that a reality.

The main compromise is switch to investing up front to achieve a long-term payoff (which is how most wealthy people become that way, and they end up having a greater quality of life for longer). To use your examples, energy use in sanitation as far as I am aware is not even noise when compared to transport or heating. We will still have sanitation as long as our society has the engineering expertize to implement and maintain it.

      Energy use in refrigeration is more significant. However, it is very doable to increase the insulation. Double the insulation and halve the energy consumption. My fridge has 35mm walls and the freezer compartment has 60mm walls. If the walls were quadrupled in thickness (e.g. 240mm freezer walls, 140mm fridge walls), the fridge would use 1/4 of the energy. Will the housewife complain about the ugliness or lack of convenience? Yes. Will the kitchen need to be redesigned to accommodate it? Maybe. Will it require more up front investment? Yes. Will the investment pay off? Yes. For example, my fridge/freezer uses 500kWh per year, so at $0.15/kWh, that's $75/year. Considering that there is no reason the fridge/freezer can't last 20 years, there is $1200 or so of energy savings to be had (which will be less given time value of money calculations), this will offset the cost of manufacture, which is certainly not all in insulation costs.

      However, the fact that this is possible indicates that powering your house with "fluffy bunny" wind generators and "happy" solar panels is more than possible if the house is designed properly from the ground up to be energy efficient. If a society has made the decision that powering your house that way is the only option, then unless a miracle occurs with solar panel efficiency, designing your house to use less power is much more viable than spending more on energy. But the important thing is that in order for society to use less energy, fundamental changes in design of everyday items, houses, transport, cities etc. must occur. It's the same principle in designing a computer to be silent - buy the right parts and design it right from the beginning.

What these new processes do is to recycle the heavy elements like uranium and plutonium from the waste so that it is all burnt. Thus while you still get the same amount of fission fragments per kilowatt hour of electricity, you don't get any of the heavier stuff mixed into it.

To ensure maximum contamination the mixture could then be spiked with precursors to troublesome radioactive compounds, like radioactive iodine, strontium or cobalt.

      Assemble the whole thing in a warehouse in downtown new-york or london and then you can see why this could get rather nasty.

      Pretty much, actually. It's absolutely hideous, but there's not much of it and it's short-lived.

      Radioactives work that way. Radioactivity comes from the decay of unstable atomic nuclei. The more frequently decay events happen, the more intense the radioactivity, and the shorter the half-life. Uranium dug up from the ground is only mildly radioactive, but stays that way for billions of years; some of the byproducts of nuclear fission are intensely radioactive but only stay that way for a matter of days, and other byproducts are of intermediate radioactivity and stay that way for millennia. A spent fuel rod is mostly still uranium, but mixed in with all kinds of other byproducts. The idea here is to extract the uranium for fresh fuel, break down the longer-lived stuff and get energy out of it by doing so, and finally end up with a small amount of waste which is viciously radioactive now, but which has a half-life so short that it's less radioactive than the original uranium we dug up after maybe a century or so.

      It reduces the volume of waste dramatically, and it reduces the amount of time it has to be stored too - no more worrying about how to store it safely for ten thousand years and whether civilisation will still be around or the English language spoken and how to protect Mad Max's ignorant great-grandchildren from our wastes. Great news, right? Trouble is, it's tricky to do, and by tricky I mean expensive, so it hasn't really been done on a large scale. Especially since the last couple of decades have seen massive nuclear disarmament which has flooded the market with plutonium.

      From Wikipedia:

      Fission products in power reactors

      In a nuclear power reactor, the main types of radioactivity are fission products, actinides and activation products. Fission products are the largest amount of radioactivity for the first several hundred years, while actinides are dominant roughly 10^3 to 10^5 years after fuel use.

      And:

      Pu-239 is normally created in nuclear reactors by transmutation of individual atoms of one of the isotopes of uranium present in the fuel rods. Occasionally, when an atom of U-238 is exposed to neutron radiation, its nucleus will capture a neutron, changing it to U-239. This happens more easily with lower Kinetic Energy (as U-238 fission activation is 6.6MeV). The U-239 then rapidly undergoes two beta decays. After the 238U absorbs a neutron to become 239U it then emits an electron and an anti-neutrino (\bar{\nu}_e) by decay to become Neptunium-239 (239Np) and then emits another electron and anti-neutrino by a second decay to become 239Pu:

      And:

      Most plutonium is produced in research reactors or plutonium production reactors called breeder reactors because they produce more plutonium than they consume fuel; in principle, such reactors make extremely efficient use of natural uranium. In practice, their construction and operation is sufficiently difficult that they are generally only used to produce plutonium. Breeder reactors are generally (but not always) fast reactors, since fast neutrons are somewhat more efficient at plutonium production.

      In other words, hella huge quantities of actinides are produced in fission reactors in addition to the fission products. Since only a small amount of the fuel is actually burned, the majority of the waste is actually some form of actinide. They are primarily five actinides (only one of which is not a radioactive isotope) in particular: uranium 238 initially, which absorbs a neutron to become Uranium 239, which decays almost immediately into Neptunium 239, which decays further into Plutonium 239. The plutonium 239 then occasionally absorbs a neutron to become plutonium 240.

      Get it? This happens in all fission reactors that use uranium as fuel, which is all commercial fission reactors. Breeder reactors are simply designed to produce as much plutonium 239 as possible, without producing plutonium 240.

It should have signaled that something is going wrong in the reactor. This is the type of event that should be signaled as a LER even if it seems insignificant. At the Davis Besse plant I believe that it led to criminal charges as management allowed the plant to operate outside of it's "Basis Design" which is a known operational characteristic of the plant. Filter replacement intervals had been defined and were known about and thus should have characterised the plant as "not operating safely". I'm not sure if the criminal charges were placed because management should have reported several LERs instead of inspectors finding a hole in the reactor head when it was shutdown.

      Whilst this issue was resolved, it shouldn't have even occurred. There are questions regarding the operational safety of Vermont Yankee and Palo Verde so it's a current issue.

      Nuclear is comparable to coal with a different set of externalities. Wall Street doesn't like nuclear because its a risky investment, investors don't like that sort of risk, solar and wind are way ahead simply because the return on investment is much better than nuclear, i.e. Solar and wind satisfies the criteria that makes an investment "economically viable" nuclear power is only "economically viable" with substantial regulatory support.

      The breakdown of U.S energy research and development reported by the US DOE is roughly 60% for nuclear, 25% to fossil fuels and 15% to SUSTAINABLE energy sources. The reality is that nuclear power has very high energetic inputs to process the ore, reprocessing and enrichment that comes from fossil feuls (2*1Gw coal plants for Paducah) which haven't been replaced. They rely on heavy carbon inputs for the concrete for the reactor containment, have energetic input subsequent to the end of the operational lifespan of the reactor, have higher energetic requirements for demolision, higher energetic input for logistic management (like transfer of the "waste" outputs).

      In comparison solar, wind, wave and geo-thermal have initial carbon inputs(today) but offset carbon while they operate, do not continue to require energetic inputs at the end of their operational lifespan and do not require additional energetic inputs for demolition. Wind, in particular, scales very well.

      One of the core reasons I support the development of such a reactor because it is capable of utilising weapons grade plutonium as fuel creating an impetus for disarmament and, hopefully, slowly defusing the asymmetrical weapons threat.

      Unfortunately, because there is no geologically sound Nuclear waste dump in operation it's totally inappropriate to discuss building a new reactor facility until a proper containment facility is available. As discussed Yucca mountain is not a suitable site because it is made of pumice and geologically active evidenced by recent aftershocks of 5.6 within ten miles of a repository that is supposed to be geologically stable for at least 500000 years. The DOE's own 1982 Nuclear Waste policy Act reported that Yucca Mountain's geology is inappropriate to contain nuclear waste, and long term corrosion data on C22 (the material to contain the Pu-239 and mitigate the ingress of water - yet another Yucca problem) is just not available.

      We need something made of granite.

Energy efficiency, a solution at the core of RMIs work, was discussed as a viable and economically profitable resolution to both energy and economy issues. New York Times writer Kate Galbraith points out that RMI and Amory Lovins have consistently advocated the benefits of a soft-path approach to energy, with efficiency at its core. You can read the article here.

    When it comes to nuclear power specifically, every dollar invested in new US nuclear electricity will save approximately 2-11 times less carbon, and will do so roughly 20-40 times slower, than investing in the same dollar in energy efficiency and micropower (cogeneration plus renewables minus big hydro dams). Buying new nuclear capacity instead of efficiency causes more carbon to be released than spending the same money on new coal plants!

    There is or was a mine in Namibia, the Rossing mine IIRC, that gets uranium out of 0.03 percent ore, but that probably depends or depended on very cheap labour. Most places the trend in the last 20-to-30 years has been to much higher grades, because that's what prospectors have been finding.

    To within a half-order-of-magnitude, they've been finding about a thousand tonnes per day, and the cost of this finding has been a million dollars per day. That may sound like a lot, but the world's current oil burn rate is only a thousand tonne-U-equivalents per day, and for
    petroleum propectors to find a kilotonne-U-equivalent has been costing $500 million.

    If any large contingent of government-funded people really believed uranium was running out, they could accelerate the process by buying it and taking it on long ocean voyages and, on the way, dissolving it in acid and losing the solution overboard. By losing a dollar's worth of uranium in this way, they could force electricity vendors to burn $20 worth of natural gas instead; government would make more than a dollar on that. And the oceans would not be harmed. Not at all. Can you guess why not?

    Anyone that seriously believes that we can get out of the current situation through "energy efficiency" is seriously deluded. If there was a way to effectively (not even efficiently) store energy so that wind and solar could be used 24x7x365 we could have a chance at doing that. But there isn't an effective way to store energy today and so with much of the load coming after 5PM in the US there is no way that wind or solar are going to really help all that much.

    After 5PM is when people get home from work, turn on the cooking appliances, turn down the air conditioner (in the summer) and turn on the TV. There is a huge load increase and it is way past the peak time for solar. Wind? Maybe, but the problem is that it is always "maybe".

    The simple answer is to just turn it off. If there isn't wind power available, no TV. No computers, no Internet. No air conditioning. The US lived like that in the 1930s and the standard of living was a lot lower then so we could certainly get along. Use ice instead of refrigeration. Use batteries. Use whatever there is as long as it doesn't depend on a steady supply of electricity.

    This would certainly be a "conservation" choice. If it deterred some growth, some additional resource usage this too would be welcomed by folks that think we can conserve our way out of needing more electricity.

    It is too bad what you are saying doesn't make sense.

    1. Are you talking about the (so called) problem of renewables being intermittent, or of efficiency? These are separate issues, but you have conflated them.

    2. Solar Thermal generates electricity for hours after the sun goes down. Not all night long, but much longer than solar-voltaic. Certainly long enough to deal with much of the people come home, turn on TV and AC's.

    3. In any one place, the wind is not always blowing, but the wind is always blowing somewhere. Enough wind power in enough places overcomes the intermittency of wind.

    4. Some sources of alternative energy don't suffer from intermittency. Wave, tidal, geothermal, small scale hydro...

    5. Energy storage from renewables can be as simple as pumping water up a hill.

    6. Experts who have studied energy issues all of their adult lives believe that efficiency is one of the most powerful tools we have. See http://www.rmi.org/ for a good start. Saying they are "seriously deluded" is an ad hominem attack with no real substance to back it up.

    6. If you wish to turn off your electricity, I won't stop you. However, I think that coming up with solutions that allow a comfortable modern lifestyle have a better chance of the mass acceptance we need to succeed.

    If you include insulation as an advance in efficiency, you can probably get rid of most of that 5 pm air conditioning spike.

    Of course, I don't think the haves can conserve anywhere near fast enough to offset new use by the have nots, so I certainly see the need for increased production.

  64. Try googling "thorium india", look at second link by dbIII · · Score: 1

    You are not bothering to look.
    To show how easy it is to find google "thorium India". The first entry is the wikipedia page for thorium, the second is this:
    www.world-nuclear.org/info/inf53.html
    The plant is a fast breeder at Kalpakkam.
    The third link google give you is to an article entitled "India to build prototype thorium reactor" but it has a lot less detail.
    http://www.bellona.no/bellona.org/english_import_area/international/russia/npps/co-operation/31261
    Then there's plenty of others. It really astounds me how many nuclear advocates are stuck in the 1970s and don't even bother to learn much about the nuclear power they are advocating.
