CERN Physicist Warns About Uranium Shortage

eldavojohn writes "Uranium mines provide us with 40,000 tons of uranium each year. Sounds like that ought to be enough for anyone, but it comes up about 25,000 tons short of what we consume yearly in our nuclear power plants. The difference is made up by stockpiles, reprocessed fuel and re-enriched uranium — which should be completely used up by 2013. And the problem with just opening more uranium mines is that nobody really knows where to go for the next big uranium lode. Dr. Michael Dittmar has been warning us for some time about the coming shortage (PDF) and has recently uploaded a four-part comprehensive report on the future of nuclear energy and how socioeconomic change is exacerbating the effect this coming shortage will have on our power consumption. Although not quite on par with zombie apocalypse, Dr. Dittmar's final conclusions paint a dire picture, stating that options like large-scale commercial fission breeder reactors are not an option by 2013 and 'no matter how far into the future we may look, nuclear fusion as an energy source is even less probable than large-scale breeder reactors, for the accumulated knowledge on this subject is already sufficient to say that commercial fusion power will never become a reality.'"

      There are several steps that spent fuel must pass before it can be used as fresh fuel in a common LWR again. To begin with, the spent fuel contains a lot of nuclear poisons that prevent the reactor from retaining the nuclear chain reaction, so these must first be removed from the spent fuel. This is not done in a breeder reactor, but rather using centrifuges similar to the ordinary enrichment process. This produces two products: Real waste, and a precursor to fresh fuel. The waste can be transmuted into less dangerous waste in a breeder reactor or an accelerator-driven reactor. The fuel precursor then needs to have elements such as plutonium removed (unless it is meant to be part of Mox fuel) before it can be recast into its ceramic form and used again in an ordinary LWR.

      The amount of energy entering the Earth's atmosphere is, for all intents and purposes, a constant. The Sun is almost completely responsible for all of that.

      If I have a black roof on my house, my roof will absorb the sunlight shining on it and turn it into heat. If I interrupt that with a solar collector, ~90% of it will still become heat, and ~10% of it will become electricity. As I use the electricity to do stuff, it generates heat. Including the losses over the wires, etc.

      Net result: There isn't a significant difference in the actual amount of heat, only how we use the potential energy in sunlight before it turns into heat. Entropy is like that.

      As far as the other two factors, we stored a crapload of solar energy and sequestered a crapload of carbon dioxide a long time ago in the form of dead plants and critters. That matter decayed and turned into what we now call "coal" and "oil". Burning those releases both that energy and CO2. CO2 is an insulator and therefore reduces heat radiation.

The process mainly consists of separating the usable fuel from nuclear poisons (i.e. substances that accumulates during the operation of the reactor, and causes the chain reaction to slow down). The spent fuel is converted into gaseous form, the nuclear poisons and other unwanted materials are separated from the usable fuel (usually in centrifuges), and the remaining fuel is reconverted into the common ceramic form for reinsertion into a reactor.

      "More energy out than in" is not a goal unique to fusion. It is the goal for fusion because it describes every viable power plant. A gadget that doesn't put out more energy than you put into it isn't a power plant.

      The only reason this isn't a violation of thermodynamics is that when we say "more energy out than in", we're not counting the energy bound up in the fuel we put in. The long-term expense associated with energy from a given source is the availability of the fuel. (A bit more complex than that for wind, hydro, solar - there it's about plant upkeep since the fuel is free but fixed in quantity for a given plant setup.)

      Bottom line, we're using coal, oil, natural gas, and even uranium at a rate based on econimic viability (subject to politics and manipulation). We can produce X amount of oil at $Y/unit. Add some sort of fusion fuel to the economy, and what happens depends on how much of that fuel you can produce at $Y/unit or below. Of course, $Y is going to trend upward as long as we keep using oil (and coal, and natural gas, etc.).

      If, as many seem to believe, we can figure out sources of fusion fuel that produce more energy than we need at (or maybe even near) $Y/unit, then there will be an energy revolution; but the cost of those new fuels will never be 0, so even though we might be able to produce as much as we have demand for, it will still cost and the investors will indeed get paid off in the process.

      Peak Oil was really just the beginning. If nuclear energy were to take off, we would be out of uranium before the first year was over.

      From here:

      Here are the basic facts.

      In 1983, uranium cost $40 per pound. The known uranium reserves at that price would suffice for light water reactors for a few tens of years. Since then more rich uranium deposits have been discovered including a very big one in Canada. At $40 per pound, uranium contributes about 0.2 cents per kwh to the cost of electricity. (Electricity retails between 5 cents and 10 cents per kwh in the U.S.)

      Breeder reactors use uranium more than 100 times as efficiently as the current light water reactors. Hence much more expensive uranium can be used. At $1,000 per pound, uranium would contribute only 0.03 cents per kwh, i.e. less than one percent of the cost of electricity. At that price, the fuel cost would correspond to gasoline priced at half a cent per gallon.

      How much uranium is available at $1,000 per pound?

      There is plenty in the Conway granites of New England and in shales in Tennessee, but Cohen decided to concentrate on uranium extracted from seawater - presumably in order to keep the calculations simple and certain. Cohen (see the references in his article) considers it certain that uranium can be extracted from seawater at less than $1000 per pound and considers $200-400 per pound the best estimate.

      In terms of fuel cost per million BTU, he gives (uranium at $400 per pound 1.1 cents , coal $1.25, OPEC oil $5.70, natural gas $3-4.)

      How much uranium is there in seawater?

      Seawater contains 3.3x10^(-9) (3.3 parts per billion) of uranium, so the 1.4x10^18 tonne of seawater contains 4.6x10^9 tonne of uranium. All the world's electricity usage, 650GWe could therefore be supplied by the uranium in seawater for 7 million years.

      However, rivers bring more uranium into the sea all the time, in fact 3.2x10^4 tonne per year.

      Cohen calculates that we could take 16,000 tonne per year of uranium from seawater, which would supply 25 times the world's present electricity usage and twice the world's present total energy consumption. He argues that given the geological cycles of erosion, subduction and uplift, the supply would last for 5 billion years with a withdrawal rate of 6,500 tonne per year. The crust contains 6.5x10^13 tonne of uranium.

      He comments that lasting 5 billion years, i.e. longer than the sun will support life on earth, should cause uranium to be considered a renewable resource.

      Here's a Japanese site discussing extracting uranium from seawater.

      Comments:

      Cohen neglects decay of the uranium. Since uranium has a half-life of 4.46 billion years, about half will have decayed by his postulated 5 billion years.

      He didn't mention thorium, also usable in breeders. There is 4 times as much in the earth's crust as there is uranium. There's less thorium in seawater than there is uranium.

      "Because the 233U produced in thorium fuels is inevitably contaminated with 232U, thorium-based used nuclear fuel possesses inherent proliferation resistance. Uranium-232 can not be chemically separated from 233U and has several decay products which emit high energy gamma radiation. These high energy photons are a radiological hazard that necessitate the use of remote handling of separated uranium and aid in the passive detection of such materials."

      Basically, because almost all naturally occurring Thorium is 232Th, it's possible to isolate Thorium fuel chemically -- without centrifugation. In other words, a country that uses Thorium exclusively for fuel has no reason to develop centrifugation technology. On the other hand, separating 233U from 232U requires centrifugation. Thus, aforementioned countries would be unable to access the 233U they produce for bomb-building purposes.

      Also, the poor breeder coefficient of 233U Thorium reactors means that most of the 233U produced by the reactor is required to produce the neutrons that convert fertile Thorium into more 233U. If you were to remove the 233U from the reactor for use in a bomb, you would halt additional production of 233U by the reactor. Either you would have to harvest very little 233U over a long period of time, or you would have to supplement the Thorium fuel with some other fissile material such as bomb-grade plutonium (and if you already had access to that, you wouldn't be trying to produce bomb-grade material in the first place).

      Actually you are missing several facts. The nuclear industry has made at least one metric of costs cheaper, that being fuel enrichment. For example, Eurodif currently uses around 2400 KWh of energy to enrich a certain amount of uranium, using the gas diffusion process, for France's nuclear power plants at Tricastin. They are replacing that with a gas centrifuge process which can make a similar amount of uranium with 40-100 KWh. Nuclear power plants aren't built more not because their electricity is more expensive, but because it takes several years to build a nuclear power plant, years while your initial investment isn't being recuperated and hence require large loans to be constructed. Providing you can finance their construction they are the cheapest form of power generation which exists (coal is as cheap as nuclear in some places, but power plants very far away from coal sources end up spending a lot of money on fuel transportation because it has so little energy per ton compared to uranium). Nuclear energy is a long term investment : but people are so focused on short term gains today that natural gas power plants and wind power are favored instead. Instability in the financial markets is no help either as loans become harder to manage for such large construction projects.

      France made an investment in energy security by switching their electricity generation to nuclear power, after the 1970s oil crisis made electricity generation from fuel oil uneconomic. Italy and Germany choose to close their own nuclear power plants because its the "green" thing to do. The result is that they are now buying a lot of electricity from France, because they cannot generate enough cheap electric power on their own.

      I'm looking for the article I saw saying that nuclear costs more than wind, at the current prices that GE will charge you if you want to order a new reactor or a new plant. It's around here somewhere. Think it was in business week or the new york times.

      Anyways, nuclear is by no means as cheap as coal. Can't be, if the decomissioning costs of one plant add up to several cents per kilowatt hour that the plant ever produced. And reducing the cost of reprocessing slightly barely affects the main driver of cost : building and running such an immense pile of expensive and dangerous capital equipment. A nuclear reactor has to have parts in it used in nothing else on the planet, all made to a very high standard of quality.

      Yeah, the French way might just be affordable, but it would be tough to make it happen in the U.S. Not only do the French do reprocessing, but every one of their plants is a copy of each other. That last bit would simplify a lot of the current problems, and would make a new plant cost a lot less.

      Anyways, I have thought about how to do nuclear right. You'd have to agree on a single, standardized design or two. The Federal government would have to guarantee a lot of things, and carve out places near a supply of cooling water to build them. There would be a few huge sites with dozens of plants all located next to each other, so that backup systems and safety systems could be shared between the plants. Each mega-site would have a single waste repository or reprocessing plant (so you don't have to transport the hot stuff anywhere) and would be guarded by federal troops with heavy weapons. (could even give it a Patriot missile battery so that airliners and missiles couldn't be used against the site)

      We'd have 4 or 5 of these locations that would supply the base load power generation needs of the entire nation. Consolidating all the plants near each other would also greatly reduce the number of trained personnel you'd need to run the plants, since you could have a small number of real experts working there with PhDs, an emergency response team that knew what they were doing, and so forth. There would be ways to cross connect the plants such that if one plant's cooling system failed you could bring in giant hoses and use the system off of the reactor next to it. Individual firms would own each reactor, but they would be required to pay into a common fund used to pay the workers who had jurisdiction over the whole site.

      These mega sites would be located on the least valuable land that is far from a populated area as possible, with a special high speed rail link between the site and the residential areas for the families of the workers.

The uranium concentration of sea water is low (approximately 3 ppb) but the quantity of contained uranium is vast - some 4 billion tonnes (about 700 times more than known terrestrial resources recoverable at a price of up to $130 per kg). If half of this resource could ultimately be recovered, it could support for 6,500 years 3,000 GW of nuclear capacity (75 percent capacity factor) based on next-generation reactors (e.g., high-temperature gas-cooled reactors) operated on once-through fuel cycles. Research on a process being developed in Japan suggests that it might be feasible to recover uranium from seawater at a cost of $120 per lb of U3O8.40 Although this is more than 10 times the current uranium price, it would contribute just 0.5 per kWh to the cost of electricity for a next-generation reactor operated on a once-through fuel cycle-equivalent to the fuel cost for an oil-fired power plant burning $3-a-barrel oil." [emphasis added] 40 Nobukawa 1994: H. Nobukawa "Development of a Floating Type System for Uranium Extraction from Sea Water Using Sea Current and Wave Power," in Proceedings of the 4th International Offshore and Polar Engineering Conference (Osaka, Japan: 10-15 April 1994), pp. 294-300.

We will collect the radiation energy with photovoltaic cells pointed to the sky. As there are no moving parts, it wouldn't require much maintainence either. Why hasn't anybody implemented such a brilliant idea?

      Solar energy is very low density. It's used in spacecraft (out til about Mars) because except for RTGs it's a lot cheaper than launching fuel into orbit. For terrestrial applications however, sunlight only has an energy density of 1500 Watts/m^2 in space, dropping to about 800 W/m^2 on earth. Factor in the 15% efficiency of mass-produced commercial PV (photovoltaics) and you're only talking about 120 W/m^2 peak production. Next factor in the movement of the sun (since you specified no moving parts) and weather, and realistically you're looking at maybe 50-70 W/m^2 on average during the day (halve this if you want average output over 24 hours). This is semi-reasonable for static applications (e.g. houses) where you can plaster a large area with PV panels. A house's average 36 kW-h daily energy use could be satisfied with about 40-60 m^2 of panels. (You'd still want to be on the grid though, so you could do things like heat the house when fresh snowfall covered up your panels.)

      But it's useless for mobile and space-constrained applications. A typical sedan requires about 20-25 hp to maintain cruise speed on the highway. That's about 15-19 kW. If you go with the lower figure, if you covered the entire upward-facing surface of your car with PV (about 6-7 m^2), parking it on a sunny 8-hour workday would capture about 5 kW-h of energy in the battery. Or enough to drive your solar car at highway speeds for all of 15-20 minutes (never mind accelerating).

      Another idea a solar advocate pitched to me was powering street lamps entirely with PV mounted on top of the lamp post. The typical street lamp uses a 250 W bulb. If you assume the light needs to be on for 14 hours in winter, it'll use 3.5 kW-h of energy. A static panel which could capture that amount of energy in 10 hours of daylight at 70 W/m^2 would need to be 5 m^2. There's no way you're mounting that on top of a lamp post. LED lighting would have to improve to the point where a 25 Watt LED bulb could provide the same light to make the idea semi-reasonable. And you'd still be talking about a half m^2 panel which although not overly large would still be highly visible and unwieldy should the wind pick up.

    I'll try to quote the least amount possible to make the point, which I'm dead certain Dyson would wish to hear people screaming from the roof tops.

Unfortunately, they overlooked a well known fact about submarines. There is not a lot of room to spare ... most important requirement ... to be compact [rather than safety] ... [more power to volume] the more quickly it will melt or vaporize in case of an accident ...

    The other thing about submarines, which I don't see in this passage, is that being submersed in the ocean is a rather convenient massively over-specified cooling system, an advantage not enjoyed by civilian power plants.

    Dyson goes on to argue small is beautiful and says that the envisioned economy of scale with 1000 MW light water reactors had proved illusory, at the time of writing. I happen to know that reactor efficiencies, for existing reactors, have increased over the past twenty years due to improved operating knowledge, so maybe that remark now needs a footnote.

    The point here is this: the original market momentum in power-dense light water reactors, which are highly suitable for nuclear submarines, goes against everything that we've know since the 1950s about safe civilian reactor design.

You get the same limitations of 1)having to run it through heat exchangers/condensers in order to provide the cooling and 2)the rate at which you can do that. So out at sea, or sitting on a river, it won't make too much of a difference, both provide a "massively over-specified cooling system". Also submarines generally like to limit the amount of highly corrosive sea water they bring through the pressure hull.

      I'd also add that that has not been a single reactor accident on board a US nuclear powered sub. They have run aground, and still operated to get back to port. Been run over and made it back to port. Hell they have even suffered other accidents causing them to sink, but with no ill effects caused by the reactor and no release of radioactivity.

Currently the mine produces around 5,000 tonnes each year, which isn't the largest (Ranger in the Northern Territory is) but if the expansion goes ahead on the scale they're planning then it will be spitting out much, much more.

    Then there's some other large deposits in Western Australia that are only now being developed as a change of government has seen the ban on Uranium mining lifted. It's even worse in the eastern states of Australia, as they have prohibited even exploring for uranium. Hooray for the luddite Labor party! The party that is okay in South Australia and federally to be mining and exporting it, but not using it here and won't even entertain discussion of the pros and cons of Australia adopting nuclear energy.

    So if there's a shortage then the price will rise (which it did in the last few years because of fears of running out of the cheap bombs) and that will spur miners to start mining already known deposits that couldn't be mined profitably at lower prices. It will also spur further exploration and eventually the price will rise high enough that it becomes more economical to reprocess spent fuel, which is apparently 90-95% still good.

    There's enough Uranium out there that we'll never run out for centuries, and then there's Thorium if fusion continues to forever be 40 years away.

      You have presented a far more insightful answer. My comment was intended to be glib rebuttal to a comment that implied that it was a quick easy fix.

      Soot: Course particulates wash out fairly fast. Fine particulates in the upper atmosphere act to cool the surface. Fine particulates near the surface. Don't know. The latest plant at Genesee (my neighbor) has no visible plume at all. They really are quite good at cleaning up their emissions.

      C02: I think the IR that can be blocked by CO2 is mostly blocked now. I suspect that further CO2 releases will have an increasingly marginal effect. Still some. Beyond my knowledge to calculate.

      Thermal: Overall a 1 GW solar photoelectic plant will be a worse thermal source than at 1 GW coal plant -- at the location. The solar plant will locally put in about 9 GW of thermal (figureing 10% efficient cells) The Coal plant about 2 GW thermal (figuring 33% thermal efficiency) If you take into account the light that would be absorbed anyway by the land the solar plant is on, that 9 GW is much smaller. Comes out to pretty much of a wash either way. But the coal plant is adding energy that hasn't been seen for a long time.

      This post shows that the issue is complicated. All the posential solutions have difficulties. At present my take on the potential answers:

      1. If we are going to burn coal, burn it in solid carbon fuel cells. This has the advantage of much greater efficiencies, and the CO2 is already separated for sequesterization. This technology is still experimental.

      2. If we are going to do solar, solar thermal shows more promise, with the potential to store enough heat for night time operations. Photo solar has promise for off grid use, but currently, battery technology is a sticking point. (The thought of recycling a household's worth of lead acid batteries every three years for every household is daunting.)
      Both technologies require specific climates to be efficient. (But see Germany. If ever there was a place where solor shouldn't work...)

      3. Wind for suitable sites mixes better with agricultural, pastoral, and recreational use than does solar. Of the completely renewable sources, I think it is cheaper per generated watt hour.

      4. High altitude wind power is an interesting concept that avoids most of the intermittency problems.

      5. If EEStor's batacitor is real and comes to market it will change the entire picture, both for stationary and mobile energy use.

      6. Nuclear may be part of the solution. Frankly I would prefer to have a nuclear reactor as a neighbor than the 2.5 GW coal-thermal plant that I have now. (And I mean neighbor-- Its mine starts 1 mile from my house.)

      2. could not agree more. Direct heating of water is the most efficient way to get, well, hot water. ;) In fact, such systems are becoming popular here in the Northeast. We don't have optimal sunlight, but at 16 cents a kwh, we sure have expensive enough electricity to justify using what little Sun we get to our advantage!

      Off-grid is a decent use of solar. However, generation need not be at the household level, and storage need not be in the form of batteries.

      An experiment was proposed here in Maine that was intriguing. A company wanted to dig a gigantic hole in the ground where the Maine Yankee nuclear plant used to be. That hole would be several hundred feet deep, adjacent to the ocean.

      Interestingly enough it was designed to be, in essence, a battery.

      When power was needed, let the hole fill up with seawater, and capture the energy as electricity to feed into the grid. When excess power was available, use it to pump water back out of the hole.

      No battery technology to deal with - you're storing the power as potential energy. As long as you keep the hole empty, you have a pretty massive amount of potential energy that can be converted to electricity.

      The beauty of that scheme would be for tidal power, where you have very predictable points in the cycle where you cannot generate power (slack tide) and predictable points where you generate WAY over average power (half-tide when water is really moving fast). So you use some of the power at half-tide to generate power to empty the hole, then at slack tide use that to generate power while the tide is turning around.

      Could also be useful for wind power, though when the wind goes out you never know when it'll be back. Solar power could be a good supplemental source for this, though you'd have to have a very large hole to get through long cloudy periods around here.

      For our area, tidal for electrics and solar for direct heat (house heating, hot water) would probably be our ideal mix, maybe with a little photosolar at the house level but connected to the grid. Perhaps with one of those holes in the ground here and there to get through the bad spots where we don't get a lot of Sun (we call them "Mud Season", most people call them "Spring").

      Nuclear power has always been a panacea that, if we could just get over our fear of it, could bail our asses out of a shortage.

      Except, now, according to CERN, it's not. We're already overdrawing that account by using up all our disposed nuclear weapons for fuel.
