US Plans "Disposable" Nuclear Batteries

holy_calamity writes "A US government program is in the works to design small nuclear reactors for use by developing countries. The work continues despite fears about security and nuclear proliferation. Plans include having reactors supplied with fuel by the US and other trusted nations, or to build reactors with their whole lifetime of fuel packaged securely inside — like a giant non-user replaceable radioactive battery.'

      Like Helen Caldicott, you wouldn't know the difference between a Becquerel and a curie, and you don't even care.
      Elemental tritium has a specific activity of 9650 Ci/g, or 2700 Ci/g for tritiated water. Therefore, 5 * 10^13 Ci of tritium, assuming it is all present as T2O, corresponds to 1.85 * 10^7 L. Would a leak of 18.5 million liters of water from a nuclear power plant go unnoticed? How many nuclear plants even contain such a volume of water? Clearly, something is amiss with this figure. A little research shows that the 1996 heavy water leak at Pickering released 5 * 10^13 Bq of tritium - recall that one curie is 3.7 * 10^10 Bq. Therefore, about 1350 Ci of tritium was in fact released. Natural surface water and ground water in the environment typically contains H-3 at a concentration of about 30-40 pCi/L in northern New Mexico surface water and rainwater, as a typical example. In surface water in Poland, H-3 concentrations of around 40-60 pCi/L have been reported in the literature as typical values. US federal standards for safe drinking water impose a limit on H-3 concentration of 20 nCi/L. The 1350 Ci of H-3 released into the 1.639 * 10^15 L volume of Lake Ontario would thusly increase the H-3 concentration by 0.82 pCi/L, or a 2.7% increase over natural background concentrations. Thusly, assuming a natural cosmogenic H-3 concentration in the lake of about 40 pCi/L, this is just 0.2% of the US federal guideline for drinking water, and the addition of 0.82 pCi/L does not make any significant increase to that figure. For every picocurie of tritium consumed by an average person, her risk of cancer increases by a factor of 4.4 * 10^-10, assuming the linear no-threshold hypothesis as true. Thus, as a result of the tritium release into Lake Ontario, if a person consumed two litres of water from the lake, their risk of cancer will have increased by 7.2 * 10^-10 - 72 billionths.

In order to reduced power consumption to work, you would have to remove all the old devices and insist on the more efficient units be purchased. Is that really an obtainable goal?

This causes the markets to increase and when you add the increases in the population, you end up with the same.

    Our modern world (such as it is) is built upon cheap energy. Up to this point, we've been using oil to supply vast amounts of energy - as well as many, many products that are based upon oil. Plastics, fertilizers, medicines, etc. If you'd like to change your lifestyle to one where you have nothing other than what you can craft from stone or wood, line up over there.

    The rest of you - we can't go on like this. Other countries are "coming on line" soon and will need their share of oil, too. There's just not enough to go around; not in the long term. All the wishful thinking in the world isn't going to change this - we need to find another energy source, go back to the stone age, or fight World War Three to secure what's left of a disappearing resource.

    Those who think that hydrogen or ethanol are the solution - go to the back of the bus. There's no free hydrogen on this planet and to obtain free hydrogen you need to add energy. Current methods for obtaining hydrogen: electrolyse water (big energy) or catalytically extract it from natural gas (limited supply). There's no free energy here, hydrogen is an energy storage medium, not an energy supply.

    The ethanol solution is also based on mostly fantasy. Sure, you can ferment carbohydrates at virtually no cost other than the carbohydrate source. But distilling it to obtain the ethanol is a high energy operation. Can ethanol be distilled using less energy than can be obtained by burning it? Maybe someday, but using today's technology it's a losing proposition. And don't forget that the carbohydrate source is the same one that we call "food". Our government's current push for ethanol is the reason that Mexican farmers are plowing under their agave crops and planting corn instead. When you notice that the price of your tequila has skyrocketed, thank your government.

    When looking for an energy source, forget just looking at things you can burn to release energy. Look at things that can be found naturally in a state where they can be burned to release energy; these may be useful energy sources. That eliminates hydrogen and ethanol, both of those require energy input to manufacture.

    Until something else is discovered, other than oil the only primary source of energy we know of is nuclear power. You can demonstrate against it - and it is indeed an imperfect source of power; disposal of the "exhaust" is a very difficult problem. But it's the only thing that we've got to work with in the long term.

    Wind and water may provide some energy, but they won't be enough. If you don't want nuclear energy, suggest something else that will provide a positive energy result.

If you assume a 5-10% cost of capitol, many systems would never break even.

    Cut the cost of panels in half and double the cost of electricity and it makes sense in orders of magnitude more places, such as areas where electricity is extremely expensive, such as some European countries and California when the legislature is having a particularly large cow.

    Get the cost of an install that'll cover ~50% of a home's needs down to ~$2-4/watt and I'd expect them to be building factories to build the panels left and right. I say 50% because more than that and you'll likely need battery banks($$$) to go off the grid otherwise the power companies will start doing things like charge a monthly connection fee to pay for infrastructure and maintenance, and refuse to buy power because they have no demand when you have power to sell.

    A single watt of panel can be expected to produce ~2-3 kwh a year. If you're paying $.30 a kwh, you're looking at a payback period of around 4-5 years. That's reasonable.

Your remark that you need energy to generate hydrogen is correct, but flawed. Hydrogen is not a means of generating energy, but a means of transporting it. If you had actually read about proposed hydrogen infrastructure, you'd see that this is already understood. There are a number of problems with using hydrogen, but "you need to add energy" isn't one of them since we already have many forms of energy production.

    While I'm a big fan of nuclear power, it's foolish to say that nuclear power is the only form of primary energy production or that primary energy production is the most important aspect of a power generation system. For example, solar power satellites (SPS) are proposed arrays of solar cells in space that beam power to a point on Earth. You can have SPS systems in constant sunlight. Even if the satellite has to be in low Earth orbit (say because it can't focus microwaves very well), you can maintain a constellation of them in orbit and keep several spots on the planet constantly illuminated with microwaves. That means you now have solar power as a primary power source. Improving storage and transportation of power are ways to reduce the need for primary power sources.

What happens when it the person's *local* water supply and that's what they drink e.v.e.r.y.d.a.y, they shower in it, brush their teeth with it, wash their face and eyes, cook their food with it and it is the water that their food is grown with.

    And it is the same for the entire community, and there are other radioactive elements (if I using the terminology correctly) released into the environment which, according to your own blog, do bio-accumulate. Even if I got it wrong about tritium bio-accumulating how many other radioactive elements released by the nuclear process into the environment do bio-accumulate? So with that as a basis why don't you calculate the cancer rates for that community, because Pickering - in particular - will be a source of radioactive products well after the reactor is closed down permanently.

    Generates more used fuel than a LWR? So what? Recycle it.

    Like many Nuclear Power advocates you make a simple sweeping statement like this and ignore the actual logistics involved in achieving it. Safe extraction from existing plant based storage, safe transportation, reprocessing, more transportation. Yes I loved the idea of IFR, but - as pointed out to me by a nuclear advocate - sodium is extremely volatile, and radioactive sodium - exactly how dangerous is that, and importantly to the long term viability of the reactor - how corrosive?

    Generates large amounts of tritium? So what? Collect it - we're going to need a fair bit of it to start up ITER and DEMO. It's very valuable stuff - the fuel of the future!

    Great, more sweeping statements, no consideration of logistics. I support ITER, don't know about DEMO (is it fusion too?), but until they're operational guess where it is going to go?

    Tritium expelled into the biosphere? *How much* tritium?

    *How the fuck would I know*, however like many of the toxic externalities that the Nuclear Industry dumps into the environment *As much as they say* and they wouldn't lie would they, would they? Like I said, with respect for your knowledge, but naivety with respect to the political characteristics of the nuclear industry is at least equal.

    What dose has the community received as a result of that? How does it compare to naturally occurring tritium?

    As observed by the many other aspects of the Nuclear Industry the political supporters of Nuclear Power block funding attempts to find exactly that data, which allows people to say "no scientific study has been performed" on the toxic effects. Hardly the type of scientific approach you would support, is it?

      Dr. Helen Caldicott, (MD, not Ph.D, not that I don't respect the MD) is <b>not</b> a Nobel peace prize laureate.

      International Physicians for the Prevention of Nuclear War won the Nobel Peace Prize in 1995, but it is no more valid to say that Dr. Caldicott won the Nobel prize than it is for the 200,000 other IPPNW members to say they won it. Everybody agrees that there aren't 200,000 Nobel laureates out there as a result of the prize being awarded to IPPNW.

      Dr. Caldicott, and others like her, do a lot of very good, admirable work with regards to nuclear disarmament - and I've got a lot of respect for that. That's what IPPNW's Nobel Prize was for - these things are very admirable, but they've got absolutely nothing to do with nuclear power, which is a distinct issue.

      For all their very admirable work with regards to nuclear disarmament and the prevention of nuclear war, my respect for people like Dr. Caldicott is completely offset by my complete lack of respect for the things that they claim and say with regards to nuclear power, and peaceful, civilian nuclear science and technology.

      Anyway, back to the topic.

      With regards to the cancer risk from the tritium - you may not have known, but I did quantify it for you in the above post - it's nothing.

      The questions that you consider under "Engineering" - those are of course scientific questions. With regards to the net energy yield from nuclear power - that's a scientific question, too. And, yes, there's plenty of energy gain.

      All these issues and questions have been asked, and answered, before.

      The subsidies are not significant. They're comparable to the subsidies given to other sustainable energy systems. Nuclear electricity generation in the United States is an economically viable, successful commercial business. Yes, the energy companies are in it to make money, and nuclear power makes them money easily.

      Yes, it's a for-profit commercial business - but all industry is overseen by the government to make sure that they don't endanger the environment or people.
      Nuclear power is too, especially so.

      Would it make you feel more comfortable if all nuclear power related industry was government owned, like in France, so that no corporations are making money off it? I don't see why that can't be done, if it makes nuclear energy more acceptable because of people's distrust of the big scary corporations - it works fine in France.

      A nuclear power reactor is absolutely nothing at all like a "stationary nuclear bomb", that's just emotional rhetoric with no basis in real world physical facts. They're sufficiently secure, and not targets that terrorists could attack to cause widespread devastation. What exactly might the terrorists actually do?

      Fossil fuel facilities and chemical facilities are much easier targets for terrorists, and would be much more likely to be the basis for real destruction.

      The reason that nuclear power is so closely associated with terrorism is that terrorism can be accomplished without actually hurting or killing anybody - it's really all in the heads of the victims where terrorism occurs, and enough people let themselves be terrorized by nuclear power, and especially by those that use fear, emotion and rhetoric to campaign against it, that nuclear power is associated with terrorism - because people are scared of it, even though it's the safest form of electricity generation known, and one of the safest commercial industries in existence. Nuclear power has never hurt or killed a single person in the United States.

      Social and political systems aren't required to perpetuate the integrity of long-term disposal or storage of radioactive wastes in a deep geological repository - the longevity of that isolation is perpetuated by hundreds of meters of rock, mineral and metal, and by science and engineering today. Once the geological repository is sealed, that's it - it's a solved problem and requires no interference or maintainence by future generations - that's how those deep geological repositories are designed.

Everybody agrees that there aren't 200,000 Nobel laureates out there as a result of the prize being awarded to IPPNW.

    Conceded, I'll be more thorough checking statements written in the wee hours.

    Dr. Caldicott, and others like her, do a lot of very good, admirable work with regards to nuclear disarmament - and I've got a lot of respect for that. That's what IPPNW's Nobel Prize was for - these things are very admirable, but they've got absolutely nothing to do with nuclear power, which is a distinct issue.

    I contend that until a reactor is available with the characteristics I described in my earlier post the nuclear power industry is closely related to maintaining a state of preparedness for nuclear war. From my understanding the same enrichment process you advocate to recycle nuclear fuel can be used to create weapons grade plutonium. Is this the case?

    For all their very admirable work with regards to nuclear disarmament and the prevention of nuclear war, my respect for people like Dr. Caldicott is completely offset by my complete lack of respect for the things that they claim and say with regards to nuclear power, and peaceful, civilian nuclear science and technology.

    Why? Even if half of what they are saying is true, it's concerning. Not only is it possible that Nuclear power plants leak radioactive elements into the environment, we know it has happened and continues to happen. Additionally peaceful use of nuclear power will *always* be attached to nuclear weapons because *it can be done*. I've never heard of a city being blown up by a coal bomb, or a solar plant going critical. The fact is Nuclear power will never be benign, because it isn't. Not that I'm an advocate of coal, but the worst case scenario I can expect from a coal power station is a fire, the worst case scenario from a nuclear power plant is the rendering of 3000 Sqkms of land uninhabitable and nuclear fallout over an entire continent. That is the reality of a nuclear power plant, operator error or not.

    With regards to the cancer risk from the tritium - you may not have known, but I did quantify it for you in the above post - it's nothing.

    Indeed, but you did sidestep the question of *other* bio-accumulating elements released into the environment, just how many radioactive elements are created inside a nuclear reactor? And isn't it possible, indeed probable, that those elements continue to be released into the environment. Are you saying it's immpossible for those element to escape?

    The questions that you consider under "Engineering" - those are of course scientific questions...

    ...that remain unanswered. Simply put, there has never been a commercial nuclear power plant built that hasn't released nuclear elements into the environment. It's inherent in the design and indeed allowed by the N.R.C as part of standard operating procedure, and even that is not allowing for "accidents" that continue to occur, and even that does not take into account toxic byproducts of mining or enrichment. It is a wild stretch of faith for you to try and convince me that a machine as large as a commercial nuclear power plant would not have leaks in it, further, that since there are 450 odd commercial reactors around the world, not one of them has been engineered with disassembly and de-commissioning in mind which is another problem that is yet to be overcome.

    You may advocate that nuclear power is safe based on your scientific understanding that the elements produce limited harm, but I posit that if we *have*

    CANDU reactors can burn up so-called "spent" fuel from the US's LWRs, too, you know.
    Oh, and let me address this issue as well. Those 'burn-up' rates are less than 1% of transuranics into fissile ash, in addition to the characteristics I described for a functional nuclear reactor, those burn-up rates should be closer to 20%, like and IFR but without the issues of an IFR.
