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.
Almighty Deity yes thank you. A very misinformed video.
FlyingSeaMan256 very much so.
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.
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.
Jan how you can pretend from average people to understand those concepts? 70% of the people live on the planet just survive. They don’t even know that astronauts live in the space since time.

@Shimmy Shai but... i keep reading adn watching online that reactors are always like a tomic bombs and cheronobilthingy... but here, it looks soo cool! like a blue night lamp its mezmarizng
@@Jazzglenn Try reading some sources that provide actual credible information instead of fear-mongering. The Nuclear Engergy Institute's website is a good start.
@@Jazzglenn nuclear reactors are not atomic bombs lmao.
@@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. This is why nuclear energy is the safest technology we have available today: less deaths per kilowatthour than solar panels and wind turbines.
@@thekyuwa and adding to that, what went boom and blew the lid of at chernobyl wasn't the fuel itself but the water meant for cooling, which evaporated because of the immense heat. And without cooling the fuel melted through the ground.
fun fact: Light can move only 75% it's normal velocity in water as opposed to a vacuum like space. That's the ONLY reason those subatomic particles can move faster than light due to the Cherenkov Effect.
Yes she missed to say in water
Ive always thought a way to detect faster than light travel would be to simply watch for streaks of momentary cherenkov radiation.

This is a really interesting video, and watching a reactor start up is always cool. However, these are actually research reactors, which are built very differently from the ones you'd find in a power plant.
Fusion reactors ?
@@louisgari4294 No, they're still fission reactors. However, their design focuses more on producing neutrons for research purposes and less on heat. The ones you'd find in a power plant are much larger and have a ton of infrastructure for carrying steam from the reactor core to a turbine for power production.

yeah thats a significant distinction!
Does that mean Einstein was wrong?
@@boiboiboi1419 no, since the speed is relative, each material or absent of has a set speed limit, we call that limit the speed of light because light is a weightless particle that can go upto that limit. Here in water it shown as blue because the visible light is going so fast that some hit water molecules and slow down to this blue white. Essentially there so much light being generated, increasing the amount of collision that it results in blue. (I think this is it, Idk the fenomenon)
There's also the speed of light through air, glass and other materials.
Dragon Slayer Ornstein if space is filled with dark matter , does it mean speed of light relative to dark matter and not fixed?

Cool👍😊
In a sense it is if you consider that the light from your screen comes from the energy contained in the battery which was charged with a current that was produced from that uranium fission. You could say that the energy of the photons coming into your eyes does come from the fission of uranium atoms.
Different radiation. That is electromagnetic radiation. Not the ionisation radiation that you get from radioactive elements.
@@Trip_mania lol 😂
3:57 there's a misconception there, it travels faster than the speed of light IN WATER, light in water travels at 75% the speed it would in vacuum, and the electrons created by the reaction inside of the core travel through the water faster than the light IN WATER, this clarification is needed, light speed IN WATER
Thank you for the clarification.

actually the water is perfectly fine to swim in as long as you stay towards the top. If you dive all the way down to within a couple meters of the reactor then youre dead.

Scientists talk the talk, but Engineers walk the walk. Marvelous piece of craftsmanship. An unfathomable contraption. I dread to think of the man-hours used to design the complex, let alone construct it.
Both scientists and engineers do their job, that's all. One involves building big machinery and the other one involves discovering the principles that are used in these machinery, including how to design the composition of the steels that engineers will use to build anything, including the special alloys that need to sustain high doses of radiation.
Physicists create the math, Engineers create the machines that harness the math.
Technicians prevent them both from getting blown up.
Draftsmen used to be a link in the chain, but AutoCAD has been enabling engineers to create defective drawings for decades now.
Become both
Don't forget, both are useless without a machinist.

hi thanks for your comment.
But what exactly do you mean?
@@WorldTopONE so how long does the fuel last before it needs replacing again?..months,, years?
@@WorldTopONE A "thermonuclear reaction" is what happens inside a hydrogen bomb. It does not occur in a nuclear fission reactor. 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.
@@joevignolor4u949 First of all, thank you so much for your concern.

and I'm also pleased that my vidnl watch people who understand this!!
"Take him to the infirmary hes delusional"
0:03 this is not a thermonuclear reaction. It is fission of uranium. Thermonuclear would be fusion of hydrogen into helium or the like.
yes. And Tcherenkov effect is due to the particle which is faster than light in THE SAME medium.. It's not the speed of light in the void!
yep 3s in an im like nope there's no real science here....
Correct.
it’s actually fusion taking place fission happens in the sun and we’ve only managed to achieve fission for microseconds at a time, fission takes place in the sun combing elements into heavier ones e.g hydrogen to helium and releases millions of times more energy. 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. This is the GCSE way of naming so it may not be sufficient to the American education system.
Yeah but you sure can't have the effect of instilling fear if you use the correct terms.

This would fail you at an exam. This is not a "thermonuclear" reactor or reaction, it is nuclear _fission_. (Thermonuclear is a typical adjective related to nuclear _fusion_.) Cherenkov radiation is not "radioactive fluorescence", but it is indeed light emitted when "charged particles move faster than the speed of light" IN A MEDIUM, like water (they are still slower than light in vacuum).

Not much in this case. There is no xenon build up in those reactors atm.
@@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.

Cherenkov radiation coming out of a reactor core is about as bizarre as sound coming out of a power tool.
Cherenkov's Radiation/Emissions is absolutely beautiful
This is a fission reaction, doing nuclear fission. Thermonuclear means fusion, usually fission in a hydrogen bomb. Also the Cerenkov radiation is emission of light from media such as water when rays which can really be from any source but are produced in abundance in nuclear fission or high levels of nuclear decay pass through it. They are moving faster than the speed of light in that medium (but not fast than the speed of light in a vacuum, we have several really good reasons to think that that isn't even possible) and so the particles cause energy to radiate analogous to how a plane or bullet moving at past the speed of sound will create a

If you only knew that we you see as a glowing blue light is literally a “sonic boom” from the radiation produced traveling faster than light in the medium (water). This leads to compression of the light before it hits your eyes or the camera thus blue shifting the light. This is a little more complicated than a dye placed in a toilet cleaning solution.

Very Cool. Thanks for the awesome Vid.
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.
In simple to understand everyday language Cherenkov radiation and the cobalt blue iridescent glow in the highly demineralized water is due to electrons trying to slow down to the speed of light
"... trying to slow down to the speed of light" ... of the surrounding medium, aka water in this case.
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.
Deionized
Never seen before thanks

So basically it’s a super powered heating element. Interesting.
I was just thinking the same. We have come so damn far from basic fire but we still ultimately use a steam powered engine to power our homes.
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.
I like how you can see the Control Rods drop in to stop the reaction.
Imagine falling in, while its on, wearing or caught on something extremely heavy and you just float down to the core....
That's the reactor's power level...
This not a power reactor......as suggested. It is a research reactor and produces no electricity. Max thermal power likely no more than a couple of megawatts.
TRIGA has been safely pulsed, by yanking the control rods out at high speed, at up to 22,000 megawatts. Its designed with prompt negative fuel temperature coefficient, so it rapidly reduces reactivity as its uranium zirconium hydride fuel temperature increases. Yea, research reactors are used, among other things, for making new isotopes by exposing samples to the strong neutron flux in a small chamber within the reactor for high exposure, or in one next to it for slightly less of an exposure. They also expose samples to a neutron beam inside of a scatter chamber with detectors for research as well. Technetium 99M is one isotope they make in research reactors. It's used in nuclear medicine. I have a GI issue with food staying in my stomach for long periods of time. I've had times where I've gotten up in the mornings with food from the previous morning, and day, still in my stomach and with hellacious acid indigestion and nausea. Anyway, they wanted me to eat some scrambled eggs with Technetium 99M powder in them, to see why it was taking so long for my stomach to empty. I decided against it though. I used to work with x-ray fluoroscopy systems in a hospital, and got some scatter exposure, even though I was wearing lead vest, skirt, and thyroid shield, and used pull down leaded glass shields with leaded rubber flaps hanging off the bottoms of them, but I was using the system to fluoro lead aprons, vests, skirts, and thyroid shields for holes and defects, so the x-ray tubes were having to go up to a maximum of 120 KV and 350 mA to shine through the lead. I'm sure I got plenty of back scatter from the walls and everything in the room though. I also had lots of CT scans, a barium swallow with a bunch of scans, and an upper and lower GI before they wanted to do the Tc99M, so I figured I had, had enough rays to do me for a while.
I didn't want Cherenkov glow coming from my nuts!
😁😁😁 JK
nice to see you guys gave credit to the originals who did the video
This is amazing!
)))
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.
I wasn't sure I heard her correctly! When dropping a Thermo in there, I thought I misunderstood! LOL! Good catch.
They're showing a picture of a TRIGA (Training, Research, Isotopes, by General Atomics) research reactor, and explaining how a power reactor turns water to steam to turn a turbine and a generator to produce electricity. Research reactors do not produce power. It's very confusing.
This is true, They are mostly used for "doping" silica.
They totally do produce power. The power is just in the form of ionizing radiation and neutrons since there is no turbine attached to the cycle.
@@matthewjames8127 You're right, of course. I should have said research reactors do not produce ELECTRICAL power.
Wow this cool man
I thought reactors are started by pulling out the boron rods, so I imagined the glow would appear gradually instead of an instant flash?
Neutron source to initiate reaction.
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.
>from the beginning of a thermonuclear reaction
Uh no, a thermonuclear reaction is what we call fusion reactions, not fission reactions. This is because fusion is driven by enough heat and pressure whereas fission is driven by enough fuel mass and neutrons.
i have a simple question but im searchibg for an answer since 3 months : The reactor is start up . for how long he stay in action ( minutes or hours ) before shut it down by the control barres . please answer me . thank you
@@hassenkhaled7345 are u asking about the life of a single fuel rod??
@@hassenkhaled7345 the reactor you can keep running for as long as the fuel live
maybe 50 years ..maybe more
thank you but im asking about the operation . the action . the fission . how long the reactor stay On ( like in video ) before shut it down to cool it . how many minutes or how many seconds .
im not asking about life of reacotor or fuel . i just want to know how long it takes the fission operation ...
The presentation is confused by mingling research reactor operation with electric power reactor photos and narrative. If you see a pool of water it is a research reactor operating at much lower temperatures. Cerenkov (pronounced Sir-N-Cough) radiation (the blue light) is generated when fission-generated nuclear particles (beta particles [high energy electrons] and neutrons) that leave the fuel rods travel faster than the speed light (photons) can travel through water. The pulse of light does not come from any launch of the reactor, but from a rapid power increase from a previously low power level and inherent return to low or zero power.
What do you mean by a pool of water beeing a research reactor? I think all of the swedish powerplants have the reactor submerged in water
Yes, all Swedish reactor fuel cores are submerged in water. But, the water is sealed inside of a pressure vessel, not in an open-top pool. The pressure vessel allows reactor core temperatures to be well above the unpressurized 100C boiling point of water and generate high pressure steam (either in the reactor vessel for Swedish boiling water reactors [Barseback, Oskarsham, Forsmark, Ringhals-1] or in an attached steam generator for Swedish pressurized water reactors [Ringhals 2,3,&4]. Open pool reactors, research reactors, cannot supply pressurized steam to turn a power generator turbine. @@perhenrikhaugskott2184
actually it called Cherenkov. not cerenkov. And pronounced with F at the end.
Okay thanks again for your time
Amazing.
I know that it's highly deadly to swim in the pool but my monkey brain is like:
Haha bubble water go blue
😂😂😂👍
Question: What causes the sudden "pop" activation and blue light? What happens? What do the operators do?
fission
Pop comes from the champagne bottles they open after flicking the switch
By pushing the fuel tablet to attain a certain mass,and there it starts..
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.
@@nickc8819 no, it's the sound of control rod moving. If you watch, you'll see the rods move
Beautiful 😻
I love the popping sounds when they come on.
Even my phone vibrates when nuclear reaction starts!!
I just came to comment. It's not a strange phenomena. It was discovered freaking 80 years ago by a Russian physicist. He got a nobel for that in 1950s
This is simply amazing 👏🏽👏🏽👏🏽
Cherenkov radiation is defined as radiation emitted by a particle when it attempts to exceed the phase velocity of light for the medium thru which it is traveling,
