Today, in things I’d read on a fading screen in a half destroyed building in a Fallout game…

    I’m thinking it would be a great idea to power nuclear plants, which are desperately needed, but…

    “If there were adults in the room and I could trust the federal government to impose the right standards, it wouldn’t be such a great concern, but it just doesn’t seem feasible,”

    Trump’s selling plutonium as if it’s a regular resource, like iron ore or timber.

    So what if any of this material slips out? Dirty bombs aside, I don’t think it’s too hard to make an implosion device. 3-stage thermonuclear is a whole different game, but a Trinity style bomb is 80-yo tech. Don’t think one needs the hyper-precise tooling, timers, exotic materials, etc. Anyone know more than I?

      You don’t want to look up how many orphan nuclear devices exist in the world.
      Just to whet your whistle a bit… this is by no means an exhaustive list. https://en.wikipedia.org/wiki/List_of_orphan_source_incidents

      We’re still discovering lost nuclear power devices from the collapse of the Soviet Union. Nuclear accidents have happened from abandoned medical radiotherapy machines, and from radio imaging equipment used in industrial applications. It’s not actually that hard to find nuclear material in the wild you could use in a dirty bomb.

        Weapons grade nuclear material is a whole different ball game from the merelly highly radioactive material needed to make a dirty bomb.

        A bomb made with the stuff that’s not “weapons grade” won’t reach critical mass so there’re isn’t a nuclear detonation - all you have is a conventional bomb that spreads highly radioactive material.

        With the weapons grade stuff you can actually make a nuclear bomb (rather than merelly a dirty bomb), so something powerfull enough to wipe out a city rather than merelly contaminate a couple of city blocks.

        This is why “weapons grade” nuclear material is much more tightly controlled and way harder to get your hands on that merelly highly radioactive materials.

        Fortunatelly it’s also way harder to make (you need either a breeding nuclear reactor or special equipment to separate the U-235 isotope that can be used to make a nuclear bomb from the much more common U-236 one which cannot from uranium ore, and since these are two isotopes of the same heavy element, they are very hard to separate, hence all the talk about special “centrifugues” in nuclear weapons programs) hence people and even nations can’t easilly get their hands on it by merelly making it or processing it from raw ore themselves.

          That just means it is purified enough to be usable in a weapon. There’s also lots of different plutonium isotopes, each with various suitability to weapons vs energy.

          We need a lot more info to have an informed conversation than a blanket statement like “weapons-grade plutonium”. And I definitely don’t trust any major media outlet journalist at this point to have any idea what the fuck they’re talking about, especially with regards to anything nuclear. They regularly get things wrong or even completely backwards from reality with less complicated topics.

          Especially since the actual Financial Times article that uses that phrase being referenced by this article, is locked behind a paywall.

            There’s also just the fact that “weapons grade” just means it’s useful for a fission weapon. Nothing’s stopping you from taking that cobalt-60 you found in that Therac at Daryl’s junkyard, strapping it to an IED, and using that as a dispersal device to give a lot of people radiation poisoning or whatever (the traditional “dirty bomb”).
