Wikileaks Releases Early Atomic Bomb Diagram

An anonymous reader writes "Wikileaks has released a diagram of the first atomic weapon, as used in the Trinity test and subsequently exploded over the Japanese city of Nagasaki, together with an extremely interesting scientific analysis. Wikileaks has not been able to fault the document or find reference to it elsewhere. Given the high quality of other Wikileaks submissions, the document may be what it purports to be, or it may be a sophisticated intelligence agency fraud, designed to mislead the atomic weapons development programs of countries like Iran. The neutron initiator is particularly novel. 'When polonium is crushed onto beryllium by explosion, reaction occurs between polonium alpha emissions and beryllium leading to Carbon-12 & 1 neutron. This, in practice, would lead to a predictable neutron flux, sufficient to set off device.'"

      To quote the analysis by Wikileaks:

      This diagram is not really a secret to foreign intelligence services; nobody is going to be surprised by this design, just by the fact that it's appeared in public. Open sources have speculated on these matters for a long time (see nuclear weapons design article in Wikipedia), and this just confirms that they were right. (The structure of the neutron initiator is elegant, and interesting, however.)

      This is a crude, but effective, plutonium based design. Devices that are orders of magnitude more efficient are possible. A disclosure of, for example, the plans of the W-88 or a Russian equivalent, would be far more threatening, as there are actually real secrets involved there not known to all the NWS (the Big-5 + India, Pakistan, Israel, North Korea) or Virtual NWS (Germany, Japan, Sweden, South Korea, Canada, Ukraine, Taiwan, Italy, Spain...to name a few) intelligence agencies. After 1949 or so, disclosure of this would not have been a real threat to U.S. national security.

      The real problem about building one of these designs is the rarity (at least outside of NWS nuclear facilities) of plutonium and polonium, as well as the ability to fabricate sophisticated high explosives to exacting specifications. We're not talking about IEDs here. To build a nuclear weapon requires a state.
      I do still think (as they say) that it is interesting that the documents have surfaced at all. I am very impressed with the even handedness that Wikileaks shows in providing possibilities for a hoax but also potential evidence to the contrary - it's somewhat of a breath of fresh air compared to much of the sensationalism that we are often subjected to on subjects much more trivial than this.

      The Trinity design, and by extension the first Soviet and British weapons, was a solid sphere of plutonium at the centre of which was the neutron source known as the initiator, or by its designers - the Gadget. There was a subcritical mass of plutonium in the bomb, but if it was compressed it would become supercritical and explode (compressing, reduces the distance between nuclei making it more likely that a neutron from one fissioning nucleus will hit another and propagate a chain reaction).

      The compression was achieved using a sphere of high explosive lenses which when detonated acted to symmetrically squeeze the plutonium core into a tiny fraction of its original volume. At the same time, the initiator would be crushed, rupture and begin spilling additional neutrons into the core of the bomb. The timing here is crucial, there is actually only a tiny tiny fraction of a second for the bomb to reach optimum conditions for fission, so even though the initiator spits out billions of neutrons, only ten or so are present at the crucial moment!

      The Trinity design was pretty much obsolete in the US from about 1948 when the US exploded a series of bombs in Operation Sandstone. These weapons used a so called levitated core - a hollow core of plutonium rather than a solid core. The hollow core allows for much greater compression and allows plutonium to go much further. It also led to smaller, lighter weapons that could be put on a missile.

      The broad design of Trinity has been known for some time now, but what has been much less understood are the designs of the explosive lenses, the detonators for the lenses and perhaps most secretive - the initiator.

      Knowledge of the initiator design was crucial for the Soviet Union to explode Joe 1 in 1949, they got that from spies within the Manhattan Project, including Klaus Fuchs who had been on the initiator design team. When the US excluded the UK from nuclear weapons research (despite the UK providing them with many of the key technologies), Fuchs and co. went on to help design the first British weapon, Hurricane, which was detonated in 1952 a few days before America exploded Mike, the first true hydrogen bomb.

Plans to invade Iran/Korea: The US has plans when it invades places? seriously tho if the US invades Iran or North Korea, that would be bad and wrong, I hope any plans are exposed, the US shouldn't do it. Defense of Taiwan plans: lets be brualy honest, the plan is: fuck 'em, let the chinks take it.


      ok ok, seriously, joking aside. The answer to all these is basiclly this: Do you not think that if someone can hand these to wikileaks, they could and would sell it the chinese just as easily? Wikileaks exposes not just the data, but the insecurity of the system.

      What would you prefer:
      Scallywag gives Tiawan defence plans to wikileaks, controversy ensues, generals get kicked in the balls for poor security, plans are rewritten, security tightened. US happy.
      OR
      Traitor gives Tiawan defence plan to Chinese, US doesn't know, wallows in self satisfaction, US gets pwned.

      As for police roit control plans, they should be released, fact is if an angry mob is about to go on the rampage, some nerd isn't going to pop up his head in the middle and say 'quick everyone down this street, the police will be waiting if we go that way' and have the crowd follow. However, if the police plan to use it against a peaceful protest, then the people ought to know how the police plan on attacking them so they can avoid being oppressed. And if the plan involves beating down and teargassing people who aren't doing anything wrong, people ought to know.

    am I the only one who thinks that this sort of information is a little too important to "leak"? No, but no one with a moderate understanding of nuclear physics would agree with you. This is a very primitive bomb design. The principles under which it operates are very well understood and have been in school textbooks for decades. If you had a supply of weapons-grade fissionable materials then this would not provide you with any information on how to build a nuclear weapon than is already available from other sources. In fact, significantly more efficient designs are also fairly easy to obtain. Getting hold of the raw materials to build such a device is significantly harder - it's expected to take Iran 5-10 years to do so with a government-backed project.

    Fission bombs are easy to build. Building them in the '40s, without computers to perform simulations on and without a huge amount of published research to build on was hard. Now it's very expensive but not particularly hard. If you're a terrorist, you are almost certain never to have the resources required to build such a device, although you might already have the required knowledge. If you want a nuclear bomb for terrorist use then finding out where some of the ones that vanished from the USSR when it broke up is likely to be a lot cheaper than building your own. If you are a nation state and want one then you probably already have the knowledge required to build one and just need the materials. Building the facilities to refine them without the international community noticing is likely to be very hard, however.

    This document is, however, very interesting to military historians. It's not the sort of think Wikileaks usually carries, since it has very little (if any) relevance to modern events, but for someone researching the history of the Manhattan Project or the end of World War II it's a valuable resource (although less so than it would be if it could be validated for authenticity).

    Iran I agree may be exaggerated as a threat, but you should consider the roll that America's wars have played in history over the past 50 years.

    Cold War Era:

    The Korean War
    Lebanon crisis of 1958
    Bay of Pigs Invasion
    Dominican Intervention
    Vietnam War
    Tehran hostage rescue

    Bush Era:

    Afghanistan
    Philippines
    Liberia
    Iraq

    A lot of these conflicts had minor US involvement, but I've listed them for completeness (Liberia involved sending "three warships with 2,300 Marines into view of the coast," and funding Economic Community of West African States troops.)

    What should be most notable about every last one of these wars, is that while some of them were major mistakes, all of them were in defense of pretty much every first world democratic country, and not just the united states.

    People seem to enjoy bashing the United States for it's mistakes, and sometimes we deserve it, but the truth is that the current balance of power has benefited pretty much everyone posting on slashdot. There have been no new world wars for a reason. The soviet union ended it's domination of europe, and was not able to press in further than they did for a reason. Every first world nation prizes it's military alliance with the US for a reason.

    The truth is that the roll that the US plays is maintaining a balance of power with democratic nations at the top, and dictatorial nations at the bottom. The truth is that without the US forces there to maintain that balance of power, this would end quickly. The other first world nations do not have comparable military forces, and largely don't have the forces necessary to defend themselves from their neighbors.

    Consider what would have happened without US forces to maintain the ballance of power:
    1. In the cold war, pretty much all of Europe would have ended up in soviet hands.
    2. South Korea would fall to North Korea *immediately* if US forces weren't there to back them up.
    3. Taiwan would end up in Chinese hands *today* if the US wasn't committed to defending them from invasion.
    4. Pakistan would have difficulty surviving without US military aid.
    5. Israel probably wouldn't survive without US backing.

    Israel is probably the most controversial of those choices, and a lot of people, myself included, are pretty unhappy with how they treat the palestinians, but I don't think anyone wants to see Israel destroyed (well... except for the people trying to destroy it) as that would cost considerably more lives than the current conflict.

    So while it may be reasonable to criticize specific US actions, it's pretty ridiculous to act like you don't want the US there defending your interests, or that you're unhappy with the status quo.
