How About a Megatons To Megawatts Program For US Nuclear Weapons?

Lasrick writes "Dawn Stover looks at the incredibly successful Megatons to Megawatts program, which turned dismantled Russian nuclear warheads into lower-grade uranium fuel that can be used to produce electricity. The 1993 agreement between the U.S. and Russia not only eliminated 500 tons of weapons-grade uranium, but generated nearly 10% of U.S. electricity consumption. The Megatons to Megawatts program ended in December, but Stover points out that the U.S. has plenty of surplus nuclear weapons that could keep the program going, without the added risk of shipping it over such huge distances. A domestic Megatons to Megawatts, if you will. This would be very cost effective and have the added benefit of keeping USEC, the only American company in the uranium enrichment field, in business."

      Th-232 is a fertile material, U-233 is made from Th-232 after the reactor is running.

      Little U-233 is available worldwide, USA stockpiles are less than enough to start 10 Thorium reactors (even the designs that need the least fissile material in operation). Thorium reactor designs that need a larger fissile inventory might consume that U-233 just to startup two reactors.
      The real problem with thermal reactors is U-238 making Pu-239, and Pu-239 only fissioning 2/3 of the time with thermal spectrum neutrons. When Pu-239 don't fission it makes Pu-240 leading to Americium and Curium production, leading to eating away extra neutrons.
      The problem is that U-238 -> Pu-239 -> Fission or Pu-240 cycle in the thermal spectrum makes only 1.9 neutrons for each 2 consumed.
      But if you have a stockpile of Pu-239, it only takes one neutron to make 1.9 neutrons on average, so it could startup a Thorium LFTR, producing U-233 from Th-232, and whatever Pu-240, Am-241 and Curium is made is kept in the reactor until it fissions.

      Perhaps you mean for a Thorium breeder reactor (that makes as much U-233 as it consumes, or a little more), shouldn't be fueled with U-235, since it's a rare isotope (hundreds of times more rare on earth than Th-232), so it's not a good idea to run a Thorium reactor with U-235 on purpose.

    The U.S. generally could deal with both the fuel availability problem and the Plutonium weapons "problem" by:

    (1) fuel reprocessing, which was disallowed by executive order of then-president Jimmy Carter, This would solve the "nuclear waste" problem at the same time, as it's not actually "waste", it's actually "unreprocessed nuclear fuel".

    (2) use of Plutonium reactors which could utilize said Plutonium in the first place (which would imply breeder/fast breeder reactors, which the U.S. doesn't build due to it's non-proliferation stance, which appears to be successful, since North Korea... er... wait...

    (3) another START treaty involving both Russia and China, so that the warhead reductions would be mutual. The current number of warheads is approximately those needed to implement the Brookings Institute's M.A.D. policy in the first place, since you pretty much have to drop a warhead within 100m of a hardened target to ensure the destruction of the target, and there are that many hardened targets. Nuclear weapons aren't magical in their ability to destroy -- in fact, the cluster bombs and fuel-air explosives we've been using in Iraq and Afghanistan have considerably more explosive power than tactical nuclear weapons.

    So in all, the proposal is unworkable until you reverse a U.S. fuel reprocessing policy set by executive order, reverse a U.S. reactor technology policy set by executive order, and then engage in arms reductions talks with people who are currently not on very good speaking terms with us due to recent foreign policy decisions.

    They simply failed to deliver nuclear's promise of cheap power. For a while they were part of a system able to deliver more kWh to the grid per Ton of earth dug up than carbon fuels, but then the all the rich deposits mined out. We've already passed peak Uranium.

    Programmes like this are an attempt to avoid the costs of decommissioning these plants for just a little longer, until it can become someone else's problem.
    In reality, all plants deriving their fuel from U ought to be decommissioned ASAP.

    Note well that LFTR and Thorium fueled reactors do not have this problem. Even at normal background levels, LFTR's are fuel efficient enough that grinding and leeching random rock from anyway is energy efficient, in that you recover much more energy than the extraction process takes to run.

    Why are U reactors so bad? Because even before they are fuelled, only 0.7% of natural U is useable fuel, and after the fuel is "depleted", usually much less than 6% of that has actually been consumed.

    The reason it can no longer be used, is because it is a solid, and the waste products have no way to escape. These waste products accumulated until they consume enough neutrons to prevent the fuel from sustaining a chain reaction safely. Attempting to increase criticality in the presence of these "reactor poisons" is what blew up Chernobyl.

    Thorium, on the other hand, is 100% fertile. Almost all (arbitrarily close to 100%) of it can eventually be converted in an LFTR to U-233 and then consumed. The molten salt form of the fuel makes reprocessing easy, allowing the waste products to be continually removed, and the fuel continually refreshed.

    But we couldn't have Thorium first, because we absolutely needed to develop natural U fueled reactors first, in order to kickstart Thorium breeders.

    Then there is the misguided idea of breeding natural U-238 into P-239. This is a very bad idea: P undergoes criticality much more easily than U, and so is only good for bombs. The original Th->U breeder program was scrapped to focus on U->P breeders, but the experiment failed - it was simply too unstable to keep under safe control, and to work at all, it required a huge inventory of P to work, so it was also likely to result in a massive mess if it fell over.

    LFTR's on the other hand, are unconditionally stable. They automatically slow down when they overheat, resulting in intrinsically safe operation. They also contain no water, and hence do not generate quantities of chemically explosive gasses such as what exploded to breach Fukushima.

    The biggest problem is that basically none of the engineering wisdom accrued from building and operating U reactors is applicable to LFTR's.
    They have different hazards. They're not pressurized, but they must handle radioactive and highly toxic gasses in large quantities. They can't fail by melting down, but they run at red-hot temperatures all the time. They don't need pressure containment vessels, but they do need attached automatic fuel reprocessing plants.

    They don't need the fuel to be manually handled at all - it's all piped around, but they do need their plants to be maintained.

    The special metal used for the pipe will last much longer than the pipes in U reactors, yet it must be made of an expensive Nickel alloy.

    The only true remaining problem, is that no-one yet knows exactly what shape those pipes should be. Graphite is needed in the core to moderate the neutrons, yet graphite pipes are known to swell and then contract with heavy neutron flux.

    The US has pretty much given up on tactical nukes.

    Even from the first of your links: "Most allies today see U.S. tactical nuclear weapons as being of political rather than military significance".

    Russia wants tactical nuclear weapons to handle the fact that their conventional forces are inferior to both NATO and (probably) Chinese forces. They are hoping that they would be able to use those weapons in a conflict without triggering the use of strategic nuclear weapons. This is the very opposite of MAD.

    Being a little unhappy here. These people are in bankrupcy. Their tech is 70 years old and they cannot figure out the tech to do better. Their senators just got done raping me and everyone in the Northwest in order to try to keep them afloat.

    reactor fuel is easy and cheap to come by. And I am sure if we need some the iranians can supply us.

    But we are not even getting close here to the real deal. Damn.

    Just in case the corporate bitch run U.S. should grow a pair of balls at some point in this day in age, and I'm not talking about bugging the cabinet of another nation as a passive aggressive corporate bitch response to a valid complaint on part of US allies, nuclear arms will be at some point necessary. The aspect that they took nukes off the table in response to 9/11 contributes to the thinking it was a false flag event when one considers what the response was to Pearl Harbor.

  49. Megatons to Megawatts... by Anonymous Coward · · Score: 0

    I have nor read the complete list of responses, so this observation may be redundant, but the author seems to be unaware of a modern commercial enrichment plant that has been in operation for about two years. Located outside of Eunice, NM, it is operated by a consortiun headed up by URENCO. It employs contemporary centrifuge enrichment technology, unlike USEC's antiquated, much more energy intensive system. USEC's facility probably ought to be closed down, decontaminated, demolished and the site remediated, it's a dinosaur.

    Unexamined is the question of the practicality if nuclear power to begin with. The whole Megatons to Megawatts program was conceived by major and influential backers of nuclear power.

    The re-licensing frenzy that followed the 2005 National Energy Policy Act's relaxation of oversight and licensing should be a cause for concern for sensible people. Metals embrittled by years of exposure to highly radioactive activities did, in fact, have a design life, which relicensing ignores. This make sense for plant operators, since the facilities are long since paid for. Continued operation of these plants is highly profitable (practically a license to print money), since the most of the liability for an accident rests with the public, not them.

    Absent loan guarantees, tax incentives, and new laws that permit utilities to bill customers for construction expenses prior to plant s going on line, not to forget public insurance because private insurers decline to insure nuclear plants, there would be no nuclear power plants built.

    The free market is quite settled on the question of nuclear power, and the verdict is... it is too expensive and too dangerous. If governments would get out of the power business we'd not be having this conversation.

    The cost of real renewables halves every few years and that is the future of energy production. Put the Uranium back in the ground where it came from, probably deep geologic disposal, and forget nuclear, it was a seductively interesting idea that turned out to be economically impracticable.
