  • Nuclear Energy Explained: How does it work?
    Nuclear Energy is a controversial subject. The pro- and anti-nuclear lobbies fight furiously, and it's difficult to decide who is right. So we're trying to clear up the issue - in this video we discuss how we got to where we are today, as the basis for discussion. Next week we'll be looking at the arguments for and against nuclear power in detail.

    If a Nuclear Powerplant goes poff every 30 years, and the nuclei that comes out takes a long time for nature to take care of, how long would it take for earth to be 100% polluted with radioactivity? And 10%? I mean the landmass. Not the population.

    I think the nuclear waste doesn't matter so lot. It isn't most important drawback and problem of the nuclear power. Important problem is limited Uranium supplies for increasing energy consumption of mankind. mankind has to find new energy that unlimited and nonpolluting like Nuclear Fusion or highly efficient Solar Generator.

    • đeri662
      đeri662 Month ago

      Uranium mining is maybe a few percent of the LCOE for nuclear power plants. Even a fivefold or even tenfold increase in mining costs woulf be acceptable and for this price, there is probably much much more uranium.

    • H3Vtux
      H3Vtux Month ago +1

      It's not toxic or dangerous if built OR run properly. Nuclear plants emit less radiation than coal plants and even less than some banana farms. It's not hard to contain ionizing radiation particles, you just have to build the right containment structures.
      Meanwhile a single gram of Uranium in a nuclear plant produce the same amount of energy as 1 million grams of coal, or thousands of solar panels.
      You use electricity, if you have a better solution to produce it go invent one. Solar, wind and geothermal just aren't going to cut it and coal is terrible for the atmoshpere.

      It;s all about money. They don't care for you. They don't care for this world. Clean energy could be achieved easily, but there is no such high profit from it as from fossil fuels, which will destroy us. But who cares? They just want more money, even if they won't be able to spend them, because they will die.

    All the "I watched an HBO Miniseries that Fictionalized Nuclear Power and was riddled with scientific inaccuracies" goof balls are running wild.
    If you're a nuclear engineer, operator, or at the very least a physicist, it pains to see these people talk.
    It also is painful to watch videos from wonderful content creators on a complicated subject that don't seem to have that great of a grip on nuclear power, or why it is so good, but I don't hold that against them. It's "expensive" because of fear-mongering and legislation. It's not actually *that* expensive when you can mass produce a standard model, like France and South Korea does.
    Also, LWRs, the way you described them, would constitute a lot of non LWRs. LWRs are unique in one major regard: the coolant and moderator are both regular water, and these designs are predominantly Pressurized Water Reactors (PWRs), some are BWRs (Boiling). It's also important to note that these designs are largely based on an inspired by naval reactor designs, as that is where reactor plants first started emerging, which is why modern reactor designs are trying to get away from that, because, obviously, we can accomplish more on land than in a submarine with more efficient designs. There are no size or area restrictions. The LWR/PWR design is really great for small reactor plants, but not the most optimal for large, commercial reactors, which is what 80ish% of the world's reactors are like.. they're Gen2 Reactor Plants. I will grant that the LWR is not the "safest or most elegant" reactor design, but I think putting it in that context is a but misleading. LWRs are VERY safe, and still statistically safer than any other power production platform, outside of other reactor plant designs. Technically, a lot of our Gen4 designs that will be in construction by the end of this coming decade are safer, more efficient, and considerably more complex than LWRs, or any other current operational reactor that we have.. but they're all still very safe, and their capacity factor, at least in the US, is very high. About 90%.
    I also think it is unfair to say that Three Mile Island "barely escaped" its catastrophe. The containment vessel, which is made of reinforced steel and several feet of concrete, did its job, and it wasn't even close to succumbing. This is a prominent difference between Chernobyl and TMI, or the Soviet Era reactors and the US. The RBMK-1000 would have never been licensed in the US, for a number of reasons, including the positive reactivity coefficient and the lack of a containment vessel. Some reinforced steel and concrete would have nullified everything that die. Also, regulations are much more strict in the US, and so is the safety atmosphere in general.
    The "radioactive cloud that threatened central Europe" is extremely hyperbolic. Europe was just fine. People fictionalize the extent of radiation or how much it increased the surrounding areas.
    Here's my question. Everyone, and I mean everyone, seems to know about Chernobyl or Fukushima. Movies, series, and RUclip videos will be dedicated to them regularly, including videos like this. Yet, how's come we never hear about the worst energy disaster? The Banqaio Dam Collapse in 1975 China killed 200,000+ people and displaced 11 million from their homes, and I sincerely doubt anyone really even knows about this, let alone will we see the media talking about it. Nothing comes close to this disaster, and its environmental impact and death toll is worse than every nuclear reactor plant in history, combined. Yet, hydroelectric power is still one of the safest forms of energy, just being nuclear. *It's an example of how unfairly it is treated, fictionalized, and sensationalized.*

      It wasn't so much riddled with innaccuricies as it was oversimplifications. Worst part is that i noticed several times (particularly during legaslov's explanation) the show went out of it's way to emphasize that nuclear is actually very safe when using proper designs, or at least when run properly, but the only thing most people took away from it is "oh my goodness look at that guy in the hospital!!!!!!!! I'm emotional now and solar panels aren't scary sounding!!"
      I agree with everything else you said though.

    To the very best of my understanding, nuclear is the only way the world can stop burning fossil fuels. And it can be done properly and safely with existing reactor designs. Frankly the world needs to start building a whole lot more reactors in a hurry. Transportation is about to switch almost entirely to electric over next decade or two which will easily double electricity demand.
