  • At Reed College in Portland, Oregon, there's a TRIGA nuclear reactor, used for research. You can stand next to it and watch the blue glow from the bottom of a deep swimming pool. I had to visit.

      It's still a nuclear reactor though. Even if it is a smaller scale one. Cos that tiny bit of particle is enough to radiate that much. Now, imagine a real one, just scaled up. Redo your calculations. The principles do not change. That small reactor, may just control like 2gm of the radioactive substance, and it could give off that much light. Imagine how powerful it would be, if the weight is a lot larger ? You can do the maths.

      @@awildfilingcabinet6239 However in this case it is actually valid.
      Apart form draining the pool, practically nothing can go wrong as the TRIGA design has so large a negative thermal reactivity constant that even when (yes when) they go prompt critical, they shutdown passively and only make a 'boing' noise and a few ripples in the pool (but a huge blue glow, you can find several youtube videos showing it).
      During such an experiment, TRIGA reactors have had power outputs as high as 22 GW (although only for a few ms).
      So even if you yank out all the control rods as fast as you can, it will not melt down or even be damaged except if the water in the pool is allowed to evaporate over time (the heat released by the reactor will start to evaporate the water eventually if the cooling system is switched off for too long)

      My understanding is that things get dropped in fairly often near the edge of the pool, where the radiation is much less. If they remove the object quickly, no damage is done. I remember that they had a small wrench which had been dropped onto the reactor itself, and had to be kept in a lead box.

    I visited a TRIGA Mark 3 reactor in Main, Germany once. It was very cool, because they can pulse the reactor, which means letting it go super critical on purpose by shooting out one control rod with high pressure air, producing a lot of Cerenkov radiation at once. So i can say of myself that i was standing on a nuclear reactor going super critical at one point in my life.
    The reason you can do it is, because the TRIGA reactors use a zircon matrix for the uranium fuel. Zircon absorbs more neutrons when it heats up, which shuts done any reaction above a certain temperature because the reactor goes sup critical. Only after the zircon has cooled down does the chain reaction starts anew.
    In fact the reset time of the reactor was only 10 minutes. While i was on tour through the reactor hall it got pulsed three times, allowing us to see the radiation directly and indirectly. It really has a special kind of blue color.

      I don't have a video for you, but the blue light is from particles that are traveling close to the (vacuum) speed of light entering a medium where light can't travel as fast, like water. Since they're now traveling faster than the (in-medium) speed of light, they have to slow down and lose energy. They do that by giving off light, which is the glow you see when the lights are turned off.

    • @1997CWR

      If you search for Cherenkov radiation you should find some great explanations for it. The effect is caused by electrons that are released by the fission reaction and are traveling faster than the speed of light in water(which is only 3/4 the speed of light in a vacuum).

      That is called Cherenkov radiation, it's not radioactive, as you might think from the name, it's just light. The way it works is analogous to a sonic boom. It occurs when particles move faster than light in the water, now you might read that and see an obvious problem, but remember that light slows down when it goes through a medium, in case of water it goes at around 75% of the speed of light, so particles in the water can go faster than that. When that happens, it creates an electromagnetic wavefront than forms an expanding cone of very bright, high-frequency light. The really high-frequency stuff that is harmful gets absorbed handily by the water and what you're left with is blue light.

      Note that the Cherenkov radiation doesn't produce only blue light, that's just the interaction between the frequencies that are absorbed by the water and those the human eye is most sensitive to There's a lot more ultraviolet and violet light than blue, but our eyes don't detect purple as well as blue, and because Cherenkov radiation emits light in a smooth distribution across the frequencies, our eyes see the blue better.

    Cherenkov radiation is caused by particles going faster than the speed of light in the medium that they're traveling through. How is a much more complex question that I am equally unqualified to answer, but the wikipedia article on it is fairly detailed (but not guaranteed to be accurate, of course)
    Anyone reading that "Faster than the speed of light" thing and getting confused, remember light is slower than c - the speed of light in a vacuum - when in other media. Air slows it down a bit. Water slows it down quite a lot. If the reactor were in a vacuum and not in the bottom of a pool, it wouldn't be glowing blue. And yeah, Einstein's speed limit holds; we've yet to find anything going faster than c (with the possible exception of information transmitted from one quantum entangled particle to its partner)

    • @TasX

    This is what is known as a pool reactor. They are awesome, very safe. No pumps to worry about or pipe breaks or anything that many middle aged powered reactors have to worry about. The fuel rods are also a metalic/uranium mix which means the conduct heat very well and the reactor itself is very volumentrically small, so the heat density is not all the great. This means even if all the water leaked out, the fuel rods can cool themselves in the air. Normal ceramic fuel rods will continue to heat even after a reactor shut down to the point they melt down because they have more heat in them because ceramic is a poor conductor of heat. The outside of the fuel rod might be 300c while the internal heat is something like 2300c.
    This is why a reactor like this is totally safe to be near populations and run by relatively novice reactor operators. It is a great place to cut your teeth and get ready for the big time reactors! Even then, we are developing new reactors with different materials or designs to make powered reactors as safe as these ones. But we need to keep doing the research which these days is harder money to come by.

    Was it a good idea to have a reactor in an arts college : Whenever someone drops a phone in we fish it out with a bucket

    • @NotaWalrus1

      The water is quite deep so the phone will probably get damaged, but for a short time the irradiation shouldn't be a problem.

      The phone could damage the reactor, so it must come out.

    There used to be a nuclear reactor in Aalto University in Finland, but it was shut down in 2015 because it was too expensive to maintain (Around 400 000€)

    @jge456 Pƙed 6 lety

    We have a similar one in Italy.
    It's not operated by students themaself, rather it's at their disposal for the same purpose.
    Fun fact, it was used to identify the chemical fingerprint of Parmisan and once saved a guy with a liver mainly lost to cancer

      it's a small reactor, it doesn't even produce electricity to run more than a few appliances, I highly doubt it would do much more than fizzle in a melt down situation, it's not that big, it's just to teach these kids how reactors work and how to operate them,

      the way TRIGA reactors are built, they literally just cannot meltdown. that's just not physically something it's able to do
