Bizarre Radioactive fluorescence inside the nuclear reactor

[@almightydeity]

It's Cherenkov radiation. It's caused when electrons travel faster than the phase velocity of light in a dielectric medium. Fluorescence is purely chemical. Also, this isn't a thermonuclear reaction starting. It's simply a fission chain reaction.

[@FlyingSeaMan256]

Almighty Deity yes thank you. A very misinformed video.

[@woodywoodlstein9519]

FlyingSeaMan256 very much so.

[@tomnystel171]

Agreed. A thermonuclear reaction is a fusion reaction, involving the fusion of hydrogen and other light elements. Nuclear reactors use uranium fission, not fusion. Also, the water used for coolant cannot possibly be 300 Celsius, since the boiling point of water is 100 Celsius. It would flash into steam in a few seconds.

[@daghtus]

It always amazes me how ignorant people can be. They often confuse fission vs fusion, steam explosion vs nuclear explosion, and they all get so scared of radiation in general because they cannot distinguish between alpha, beta, gamma or even the natural background radiation. Of course it needs to be played safe when handling nuclear stuff but it's still driving me nuts when I read in some silly media how many people died due to Fukushima accident. The number of casualties directly related to radioactive contamination, in fact, equals zero. Period.

@@Jazzglenn Nuclear reactors cannot physically detonate like atomic bombs. Uranium used in reactors is also enriched by 4 or 5% max, while in atomic bombs is more like 95%. Chernobyl was a freak accident caused by negligence and incompetence. That reactor was dual purpose (military and civil), it didn't have a containment structure and was run by people who had no idea what they were doing (they had also deactivated security systems to run some tests). Today's reactors have active and passive security systems and don't have positive coefficient void. Operators need to be certified and go through thousands of hours on a simulator, just like airplane pilots.

Fusion however is when an atom is split releasing neutrons and radiation forming a lighter element that is why plutonium is the waste product of nuclear reactions and not an element with double the amount of protons than uranium, also its basically impossible to fuse to uranium atoms, the sun can only ever reach iron in its lifetime then it stops burning as it cannot fuse iron into heavier elements.

Essentially there is a plutonium fission bomb (often referred to as an "atomic bomb") inside the hydrogen fusion bomb. When the atomic bomb goes off it generates enough heat and pressure inside the bomb casing to cause hydrogen atoms to fuse together into helium atoms. This releases much more energy than the atomic bomb could release all by itself. This reaction, where the heat from the fission bomb causes fusion, is called thermonuclear because its a nuclear fusion reaction that's triggered by the heat created by a fission reaction.

@@flixri726 it wasn’t the xenon that made the reactor explode, but just the graphite. The xenon gas actually desacelerastes the reaction of the neutrons, but the graphite moderates it to make it more reactive. When the xenon was all gone, the reactor at Chernobyl started to make a lot of heat, which vaporized the water, make it moderated less the neutrons but the graphite didn’t stoped. Then the power rise quickly, and the control rods were used. As you know the graphite tips also accelerates the reaction. The water pressure finally have enough force to break the fuel rods and obstruct the way of the control rods, only letting the tips inside. The reactor endlessly accelerate to the destruction.

It drives me nuts hearing about the "thermonuclear reaction". As the name implies it only takes place at extreme temperatures and refers to the fusion of light nuclei rather than fission (splitting) of heavy nuclei which is what happens in all of these reactors, at least until one of the fusion experiments results in net energy gain.

[@viswanathks7356]

By pushing the fuel tablet to attain a certain mass,and there it starts..

[@dannywilliamson3340]

One of the control rods is rapidly withdrawn from the core by an air-operated cylinder equipped with travel stops set by the operators. This causes the reactor to go "prompt critical", reaching around 100 times its actual rated thermal power. But this power output lasts only milliseconds before it is dampened by the negative temperature coefficient of the fuel. That is, the heatup of the fuel tends to limit its own power output. It looks dramatic, but it does no damage to the fuel.

@@John-mf6ky agreed. Fukushima, Chernobyl, and Three Mile Island give Nuclear Energy a bad rap. What people need to realize is that all three of these were not only pure human error, but extremely avoidable(Chernobyl in particular). As long as safety protocol is followed and the tech is handled correctly, it’s extremely safe, the nuclear waste isn’t even an issue either, contrary to popular belief.

[@UNSCSpartan043]

There are some errors here. Yes these are reactors but they are study and testing facilities not power plant reactors. Also it's not a thermonuclear reaction it's just a fission reaction. Thermonuclear is fusion. The reason they can run these reactors without all the containment that a normal power reactor needs is because these are buried deep in a giant tank of water with a small amount of actual fuel. Water has many roles in a reactor but is actually a great moderator for nuclear reactions. The neutrons given off in a nuclear reaction that intern cause more reactions that give off more neutrons are slowed and absorbed quickly by the large heavy water molecules. That's why they can run these without all the containment and even be in the water while it's operating. A normal power plant reactor has a limited and controlled amount of water circulated in and around the actual reactor as well as a lot more fuel so it can super heat that water and turn it to steam to turn the turbines and generators for power.

You were almost right. They're not going faster than the speed of light, merely faster than the phase velocity of light through dielectric medium. Big difference.

Also you are confusing the issue when you show research reactors like at 3:05, which don't produce any power but instead produce neutrons for research and medicine and also create medical isotopes, with power reactors which produce electricity and don't look anything alike, they are rarely in a pool for instance and have cores enclosed with many layers of metal and concrete and steam pipes coming out of them.

This is not a thermonuclear reaction that would be fusion not fission. Yes heat is generated but the term thermonuclear applies to orders of magnitudes greater than those in a fission reactor.

Yes. On a normal startup, the control rods are withdrawn slowly to control the power ascent. The glow would be quite bright at 100% power.

[@henryptung]

Nuclear reactors are not "launched", and the reaction depicted is not "thermonuclear". That refers exclusively to nuclear reactions that _require_ extreme temperatures to operate - i.e. fusion, requiring high temperatures to overcome Coulomb repulsion and squeeze nuclei together. What's depicted here is fission, which has little to no dependence on temperature for reaction conditions.
