  • The previous episodes covered the science behind how nuclear reactions and weapons work, but the real barrier to building a device is the creation of the fissile material. Uranium in its natural form cannot sustain a fast chain reaction, it needs to be enriched to eliminate the non fissile isotopes, and developing this process was one of the largest projects in the Manhattan Project.
    This is largely a broad overview, much of the details are classified.
    This is Cody's video on Uranium refining for those interested in the Chemistry:

      Historically you wouldn't think that matters, but uhh... That whole thing nearly 2 decades ago (you know the one) kinda made being able to fly a plane a point of suspicion. XD
      Of course, knowing about nuclear physics surely doesn't help either.

    The silex method is so exotic and beautifully clever. They're somehow using hyperpolarized (nuclear spin purified) parahydrogen Raman conversion cells to shift a CO2 laser's wavelength to the precise infrared resonance absorption line of a U235 to F molecular bond. I would love to know how they prevent things like collisional excitation transfer to neighboring U238-F molecular bonds from ruining the efficiency.

    • @BeCurieUs
      @BeCurieUs 6 ปีที่แล้ว +7

      They actually are having a real problem with heat causing enough change in the hyperfine structure that efficiency is way bellow what they expected from lab tests. A friend of mine was involved with the early efforts and has her name on a couple of patents for these technologies, and she always tells me she loves in with foreign countries try to invest in covert laser enrichment...because they will fail and it will waste their money!

    • @Muonium1
      @Muonium1 6 ปีที่แล้ว

      Does silex exploit hyperfine structure for separation? I know that's how AVLIS works, or rather...worked, since it's been abandoned, but I assumed silex was purely using the molecular IR absorption wavelength shifts due to isotopic mass difference.

    • @BeCurieUs
      @BeCurieUs 6 ปีที่แล้ว +4

      Like the video suggests, the details are classified. But many people that have their foot closer to this than I do suggest the core principles are basically the same but with better hardware. The rumor mill suggests the heat noise problem still keeps this needing more and more funding..which is a hard ask in this land of excessively cheap uranium.

      Well depends on the bomb but getting the shape and mixture of the explosives in a classical implosion bomb exactly right is probably some seriously hardcore maths. But you can always do gun-type one. Probably not that hard, just very wasteful if you are limited in your amount of fissile material.

    • @kevlarandchrome
      @kevlarandchrome 6 ปีที่แล้ว +2

      You're right on the gun type being fairly easy, but extremely inefficient. The big problem with implosion isn't the explosive itself, it's getting all the explosive to detonate at the same time. The timers are as highly classified as the centrifuges according to someone I watched a lecture by from the IAEA.

    A lot of the non-proliferation arguments seem a bit irrelevant given that some very poor countries (Pakistan, North Korea) have obtained the bomb independently. Furthermore, once you can build your first breeder reactor, un-enriched (or even depleted) uranium can be bred into plutonium and fed back into that same reactor eventually generating excess plutonium for bombs without any enrichment process.
    Anti-proliferation restrictions on civilian power might have made sense prior to the 80s-90s but if we had gone hard on fission power 20 years ago we might now be enjoying cheap power with the lowest greenhouse gases emissions.

    • @mattiasdevlin1363
      @mattiasdevlin1363 6 ปีที่แล้ว +1

      You are correct. Proliferation concerns are mainly a political tool used to stop countries from gaining energy independance or lessen their reliance on foreign imports of energy (uranium being dirt cheap in comparison) and should be more viewed in this context. If a nation state really wants nuclear weapons there is not much the international community can do to stop them, which has been proven on at least 3 occasions so far (India, Pakistan and North Korea).

Technically speaking nuclear is a low CO2 energy source, but many who do peer review but don't like nuclear will use poor grade ores or gaseous diffusion methods as the primary enrichment to make these numbers seem poor. Also, many suspect that the R&D needed to get laser enrichment off the ground isn't actually worth it in terms of work units gained. Uranium is already so dirt cheap because of excess weapons down blending distorting markets. Until cold war inventories get depleted and uranium prices start to rise, the history lows don't seem compelling to develop laser enrichment

    Replying to a comment i saw over small yield nuclear devices.
    A Yield smaller than the little-boy would still vaporize a city such as DC completely, ie. anything over 10kt is to be considered threatening, as you can add warheads of said yield to a MIRV (*Multiple independently target-able reentry vehicle*) missile.
    Thus not all of the warhead could be intercepted if deployed before interception.
    Such that even a small yield will be devastating to an infrastructure and population, since you can have many warheads reach a single target or multiple targets simultaneously..
    You may also cause a high amount of damage by encasing the weapon in non fissile nuclear material, thus creating a dirty bomb, which the main effect would be the fallout of said device without destroying much of the infrastructure, but by irradiating the area such that the population has to leave the area.
    But you can irradiate the area to such a level that it can be easily handled by protective gear during an invasion, and then "cleaned" such that now you have the intact infrastructure without further resistance.

If so then 10kg let alone only a few kg of the total 13,335,616kg (14,700 US ton) would be three-four hundred- thousandths of one percent.

    Hundreds of tons of uranium per bomb?
    No. An average implosion type pure fission weapon like that designed by Iran requires 5.682 tons per weapon, assuming a tails essay of 0.3% U-235, which is the highest concentration considered depleted uranium by the DOE. If you have a lower concentration waste, the initial mass of natural uranium decreases.
    The lowest core mas pure U (not-composite) I know if would require 1.847 tons. The largest would require 26.592 tons.

  • @badpharma461
    @badpharma461 2 ปีที่แล้ว

    Ah, the Zippe centrifuge as designed by Gernot Zippe. I believe that LASEX (an Australian design) is now the most energy efficient. In short, a laser with a frequency that is matched to U235 (slightly different to U238) is used to inject energy into the 235UF6 molecules so they 'boil'.
    The technology was bought by the US military and details are unknown. Suffice to say that Iran still uses Zippe centrifuges.
    Although less energy efficient, if one has 'waste' energy in the form of heat, the CHEMEX process might work. I suppose if Iceland wanted to do it, hydrothermal vents would provide the energy.
    I'm also betting that the magnetic properties of uranium & plutonium have been looked into, the latter especially. It's OK to put Pu239/240/242 into a missile that people don't stand around or a bomb that is mostly in an igloo but I know that US SLBM carriers use 'supergrade' plutonium because the crew have to be around it a lot.
    I THINK the reason nuclear Tomahawk cruise missiles were dropped because the cost of supergrade is so high.

  • @williamsmith1741
    @williamsmith1741 3 ปีที่แล้ว

    Given that most U-235/U-238 isotopic enrichment processes, historically, simply separated them based on their relative masses, would those processes, like centrifuge separation, be less effective if you were separating isotopes with a smaller difference in their respective masses? The difference between U-235 & U-238 is three nucleons while the difference between Pu-239 & Pu-240 or U-232 & U-233 is only one nucleon. Would the smaller difference in relative masses of U-232 & U-233 have no impact on the enrichment process or would it require more processing equipment to do the same job, like (just throwing this out there) requiring 3X the number of centrifuges to effectively separate U-232 & U-233 or Pu-239 & Pu-240?

    Ha ha I love this the SWU was derived from the Dirac equation the gaseous diffusion method was very expensive and energy intensive something like 2300MW and you need thousands of diffusion cells,the gaseous centrifuge developed by Gernot Zippe while he was a POW in the Soviet union the first centrifuges the rotors were small less than 1m and SWU of only of 5 at the time, the Soviets had jumped onto that form of enrichment and by 1952 they had an industrial scale plant and for example quicker to enrich to what level at the moment the TC21 centrifuge has a rotor length of 5m and SWU value of 100SWU per year. The most promising one is the AC120 centrifuge and has a rotor length of 16.5 m and a SWU of 330 swu per year and energy requirements of 120KW per centrifuge. AVLIS process was promising of a higher separation value of 2.5 to 6 and the program was cancelled shame that one system had the power of 7000 centrifuges. The only hope is SILEX using UF6 gas as medium and using lasers and Australia is leading this with Japan and GE .

    For the life of me, I can't imagine why the US government cares about the people uploading content about extracting and enriching uranium. All of the content points to exactly the same conclusion: creating a problematic quantity of U-235 is totally beyond everyone without billions of dollars, and even then you'd have to somehow build all of the ludicrously sophisticated equipment without anybody finding out and stopping you (and building a stupendously large complex to house it all, without anyone noticing).
    Once you've somehow got your impossible lab together, you've got a date with some of the most terrifying chemicals known to man (I'm looking at you, hydrogen fluoride!), Being flung around at supersonic speeds. You want to enrich uranium? Fine! Have fucking fun! 😍
    It'd be WAY less work to simply hire your own private army capable of an equal level of destruction with conventional weapons. Hell, go find some cobalt-60 in third world decommissioned medical imagers, and toss it in a soda bottle. That sounds like a much, MUCH easier way to spend the rest of your life in ADX Florence 😐.

How does that work???? The slugs are irradiated in a reactor (highly radioactive), then separated in a totally shielded process canyon (PUREX), and the endproduct is extracted at a PFP (Plutonium Finishing Plant) again radioactive like hell, then it gets machined to fit a PIT or a fuellrod, and then its only shielded with some zircalloy tube or some vinyl.... Can you make a video about that?

    That we had a 'shortage of copper' is not precisely true. Copper was a strategic material and the amounts required to wind the Calutrons would have attracted notice, while the silver bars were in no particular demand and the knowledge of their use could be easily compartmentalized. It was thus the maintenance of a low-profile for the project that sparked the idea to use the silver for the electromagnetic enrichment project, avoiding the inevitable 'what on earth could they need all that copper for?' questions being asked by people who had no need to know. Silver is a better conductor than Copper, and so there was a minor improvement in the efficiency of the Calutrons. Of course some silver was lost in the production of the wire, but this was done with due care and loss was negligible. Just helping clear a point up is all. Best regards, Jeff.
