The Surprising Afterlife of Unwanted Atom Bombs (nytimes.com) 122

What happens when old atomic bombs are retired? Last month, the Biden administration announced its intention to withdraw the nation's most powerful weapon from the U.S. nuclear arsenal. From a report: The bomb is called the B83. It is a hydrogen bomb that debuted in 1983 -- a time when President Reagan was denouncing Russia as "an evil empire." The government made 660 of the deadly weapons, which were to be delivered by fast bombers. The B83 was 12 feet long, had fins and packed an explosive force roughly 80 times greater than that of the Hiroshima bomb. Its job was to obliterate hardened military sites and command bunkers, including Moscow's.

What now for the B83? How many still exist is a federal secret, but not the weapon's likely fate, which may surprise anyone who assumes that getting rid of a nuclear weapon means that it vanishes from the face of the earth. Typically, nuclear arms retired from the U.S. arsenal are not melted down, pulverized, crushed, buried or otherwise destroyed. Instead, they are painstakingly disassembled, and their parts, including their deadly plutonium cores, are kept in a maze of bunkers and warehouses across the United States. Any individual facility within this gargantuan complex can act as a kind of used-parts superstore from which new weapons can -- and do -- emerge.

      It's not like there were other choices really. This specific weapon is obsolete, for any number of reasons (both in terms of technology and military strategy and tactics), so fine, you decommission it. But there are only so many things you can do with plutonium. As far as I know we don't have any plutonium-driven reactors, and it doesn't really make sense to build one, because plutonium is too rare to be a good option for power generation. Uranium and thorium are both overwhelmingly more abundant, so you use one of them. The most obvious thing to do is to just seal the plutonium in a lead box and put it someplace safe for now. The deuterium and tritium have various uses but they're all highly technical and specialized, so you're probably going to warehouse those too, at least temporarily. The inner shielding will be radioactive, so you can't just treat that as scrap metal either.

      Not sure how specialized the other components are. If the thing has a rocket nozzle, that might be worth saving and repurposing. The fuel (and oxidizer, if it's separate) is almost certainly unspecialized and can just be used to fuel something else. If the electronics haven't been upgraded at some point, they're several decades old and can likely just be recycled; new electronics that do the same thing would be a lot smaller and more efficient and capable of much better precision guidance; but those parts may have already been replaced somewhere along the line, so they may be a lot newer than the rest of the thing. Dunno about the outer casings and such; I can easily imagine those being fairly standardized, or fairly specialized, depending. There might be bog-standard stainless steel machine bolts in the thing for all I know; if so, those can just be treated as scrap metal (provided they're not inside the radioactive portion of the warhead).

        I'm going to hazard a guess that the components of the bomb that are the reactive materials will be separated out for storage or farily quick reuse, and everything else will be treated as mildly radioactive waste and stored in the normal way that serve in lieu of disposal. Unless another device family uses those same components they'll probably never come out of whatever hole they're placed into.

        Thorium reactor designs call for a "seed" of plutonium or U-233 or U-235 to keep the reaction going. Thorium isn't actually fissile, only fertile - the Thorium fuel cycle involves Th-232 absorbing a neutron to transmute into U-233, which then has a 92% chance of fission if it absorbs a second neutron, otherwise transmuting to U-234 which is NOT fissile, but will transmute to U-235 when it absorbs a 3rd neutron, which then has a 86% chance of fissioning when absorbing a 4th neutron, and otherwise has to absorb another 4 neutrons through a transmutation chain into Pu-239 before it's fissile again... and so on and so forth. https://en.wikipedia.org/wiki/... [wikipedia.org]

        So, the number of neutrons required to fission an average thorium atom is: 92%*2 + 8%*(86%*4 + 14%*10...) = ~2.2 neutrons

        Which means that to sustain a fission reaction in thorium, you need to produce *and capture* at LEAST 2.2 neutrons produced per fission event - and while I couldn't find the formulas for U-233, most U-235 fission reactions only produce 2 neutrons to begin with, with some of the less common producing 3. So basically you have to capture *all* the released neutrons to sustain a chain reaction in thorium, but in fact a whole lot will escape into the reactor's shielding instead, so you need to add a more fissile fuel to the mix to make up the difference.

        Compare that to the typical reactor fuel typical U-235 fuel, which fissions in response to a single neutron while spitting out 2 or sometimes 3 new ones, so that you need to capture less than half the neutrons to sustain the chain reaction.

          Which is why thorium reactors will never happen outside of China. The other name for a thorium reactor is breeder reactor, and the US government has embarked on a global campaign to prevent the operation of breeder reactors everywhere, including domestically. They are the reactor design you need to manufacture significant quantities of plutonium, which can then be trivially refined into bomb grade material.

          There are only three breeder reactors operating in the world today: two in Russia and one in India.

          • That is an unfortunate historical artifact, because the fact of the matter is that a thorium reactor produces FAR less plutonium per watt than a traditional reactor.

            Traditional reactors are fueled with U-235, which has a 14% chance of entering the transmutation chain to plutonium, while thorium reactors only have an 8% chance to enter the transmutation chain to the U-235 traditional reactors start with.

Instead, they came up with a brilliant solution a while ago: lithium-6 deuteride. It's a stable solid metal that you can machine and put into your weapon, and it doesn't decay like tritium does in a single-digit number of years. When it's exposed to free-flying neutrons during detonation, it causes an exothermic reaction that produces your tritium and releases the deuterium for f

        • It is not, however, incorrect. Nukes are great levelers, which is why we have fired off so much money towards Iron Dome. We like to have the clearly superior position, and who doesn't?

      Of course, my knowledge of neutron bombs is limited, so I am guessing someone will come along a correct me.

      Neutron bombs are mainly useful against formations of tanks.

      Recent events and nifty new weapons show that we don't really need to worry about our adversaries' tanks anyway.

    • Big-dick megaton-class weapons are fucking useless. They're big and heavy, which means they have to be delivered by relatively low-flying and slow aircraft in comparison to putting several smaller warheads on a suborbital ballistic missile which presents smaller targets to try to shoot down, which fly orders of magnitude faster. And you get the same destruction by putting a few warheads into the target instead of one big ass one, because of the inverse-cube law of expanding spheres.

      There's a reason why we

  • They do it with airplane parts, tank parts, and apparently bombs.

    I have no idea why the conservatives do not want civilians to use the same tried and true military techniques, like recycling.

      Yeah. Did *anyone* actually think they just throw the thing away or that radioactive material just disappears when it's no longer needed?

  • Those things are expensive, and their parts are useful for other things. You're not going to just throw them away. That would be outrageously wasteful, even for the federal government.

  • Obviously, the device's components all have their place in the world. The arming components most likely are destroyed by shredding and/or smelting down to slag. The explosives are taken to White Sands or a similar location for disposal by EOD.

    Now the fissionables, you know the major components are all isolated and kept in separate, classified locations so they could not be recovered by Threats for reassembly. The big parts is Uranium (big surprise) and Lithium 7 Hydride. The former can be refined and use
