After the tv series Chernobyl it's been frustrating having to explain to my friends that fission plants don't blow up like nuclear bombs.
They're hallucinating, take them to the infirmary.
Blowing up is not the only concern. What about a meltdown?
there's no explosion if you cannot see the explosion. get us directly over the building!!!
@@Benderrr111 explosions are worse because the radioactive stuff gets yeeted out of the reactor while meltdowns are just a small explosion and then you the money is gone

0:01 _"Starting a nuclear reactor is a stressful task. There's a lot on the line, if a mistake is made, or if there is a malfunction."_ These are all research reactors, which are both incredibly fail-safe, and incredibly simple to operate. The TRIGA reactor, one of the most common research reactor designs, was described by Edward Teller (one of the inventors of the first hydrogen bomb) as able to _"be given to a bunch of high school children to play with without any fear that they would get hurt."_ Some, like the SLOWPOKE-2, are even licensed to be run overnight without any personnel on site. If anything does go wrong, it shuts itself down, without any human intervention, by fully passive means (no control rods need to be inserted, no water pumps are needed to provide cooling, etc.).
And many of the reactors shown in the video are pulse reactors, which don't go through a "startup" being slowly ramped up to full power and sustained - they release their energy in a short pulse then automatically switch off.
I’m glad someone else commented this so I didn’t have to
And the reason why we aren’t all using these ones are?
@@marxjester9802 Because pulse reactors are useless for power generation. You need continuous fission. And the research reactors that do run continuously are far too small to generate any meaningful amount of electrical power. Most output just a hundred kilowatts or less, with the largest only outputting a few megawatts.
It is relatively easy to design passively-cooled reactors this small, basically just stick the thing in a large enough pool of water. Doing the same for even a relatively small (1,000 MW) power generation reactor is just not feasible.
There has been a lot of work on small, modular reactors that are essentially completely failsafe. Instead of one large reactor, a large number of smaller reactors are used, each being a self-contained unit that can be individually installed and replaced as needed. Unfortunately, past experiences has made the public so afraid of nuclear power that they are pushing back hard even on these newer, safer designs.
@@Justin.Franks Totally agree, but that is seems to be changing... Many countries are investing in small (and modular) nuclear rectors isn't it?
@@alsanpi Yes, I mentioned that in my comment. Unfortunately, we're not investing anywhere near enough in SMR's right now. Russia has a prototype that is actually on a ship docked in a harbor. China is building one that won't becoming online for another 5 years or so. And that's it. Everything else is just paper designs without functional prototypes.
At this rate, it will be at least another two decades before they even start to become widespread. The public perception of nuclear power is just so damned low right now. People don't seem to be able to understand that truly failsafe designs are possible.
An American author, a scientist, wrote a book answering questions. One of the questions was how long would I last if I swam in the water that surrounds the nuclear material in an atomic power station. He asked a friend who actually worked in one. The answer was ……
seconds….
What, you mean the radioactivity is that strong?
No, the guards would shoot you
why you need a water to do this. if we didn't using water what will happen ? if it's fail
@@btnpermata444 to be able to produce Cherenkov radiation. To produce Cherenkov radiation the Schock waves need to travel through dielectric molecules (atoms that can't be affected by electric changes). The blue lights is the Cherenkov radiation breaking the sound barrier and the slowing down to the light speed limit under water
@@eliezercorderofeliciano8413 I see but I don't really understand, I think I need to learn biology more
@@btnpermata444 The water is there to cool the surroundings but also to make sure that the neutrons travel slow enough to hit other ones and make a reaction. The blue glow, as someone said above, is what happens when particles traveling at light speed get slowed down really fast by water.

That's the sound of the boron rods hitting up and down i think
@@harshtyagi1041 yupp
@@Fritter_Films yea!
It actually not dangerous at all. It's a triga reactor. You could let highschoolers run this thing with no worry.
Look up Cerenkov radiation. The blue glow you are seeing is electrons, produced by the fission reaction. They leave the core at near light speed (C). When they hit the water they slow down to 75% of C (speed of light in water) and the interaction with the water molecules releases blue photons. The blue light is the energy of slowing the electrons to the speed limit in water.
Brilliant! Unlike most others describing Cerenkov radiation, you have made it clear that its cause is not electrons "travelling faster than the speed of light", but, rather, electrons moving faster than light can travel _in water_ - which is _not_ "light speed", or C. There's much ignorance about this, with some people truly believing these particles are exceeding the speed of light (in a vacuum), which is impossible.
@@anhedonianepiphany5588 what do you mean? you say that light doesnt travel at C in water?
Nope. Only in a vacuum. @@1337Ox

this may be very interesting to watch BUT these super fast startups can be harmful to the machinery
Cherenkov radiation is hauntingly beautiful.
Beautiful...but kinda scary as well...

Only some people will understand this 🙂
@Ultra Styler Gamer I believe so
Gordon doesn't need to hear all this, he's a highly trained professional!
Most of the science fiction stuff is always blue and the fact that it actually is in real life is amazing
That's from cherenkov radiation the particals leaving the reactor move at near light speed when they hit the hydrogen in the water they slow considerably creating a effect like sonoluminescence caused by cavitation
The mantis shrimp can snap its claw closed so fast it creates a cavitation bubble that can kill prey and generate heat and light
Got to watch what you use for a aquarium for them they will easily shatter plate glass
@@terranovarain6570 i know all of this already. Actually i think it's more the interaction between the water's electric field and the electron wich moves faster than the speed of light in water that creates radiation, almost like a sonic boom. Technically they are still interacting but i don't thing they actually hit protons since electrons can simply fly past other particles as waves.
Yeah. Real life is often not as flashy. But that makes the clearly sci fi looking stuff all the better. All in all, a great coincidence.
@@WaveOfDestiny that's right. no contact is necessary. The range of electromagnetism is infinity, so just have a charge zip by at > c/n means the medium sees a line of induced charge all at once, and that makes a cone of light. Even weirder is "transition radiation".

Reading the comments, it appears that most people expected a green light. The blue glow is known as Cerenkov radiation. It is produced when electrons travels through the reactor water faster than the speed of light in water. This is similar to a sonic boom from jet aircraft. At 1:45 in the video, you see the reactor suddenly get brighter. We call this a reactor pulse. During a pulse all control rods are momentarily removed from the core in a safe and controlled manner. Its as close as you can get to an atomic bomb detonation without being in one yourself. I've stood on top of a reactor during one of these events. Pretty cool stuff.
Thank you for being the only person thus far to actually be a little careful with words, such that you don't appear to be saying electrons can travel faster than "the speed of light" (in a vacuum). It's a _very_ common misconception for people to believe Cerenkov radiation means particles can exceed light speed.
Yes, but note the qualifier: "In water". Water "slows" light down (hence a fish isn't where you see it is, if you're not looking straight down). But those particles--the electrons--are traveling faster than light travels in water; however, as they collide with water molecules, they too slow down, until they are captured in some positive ion's deficient electron shell, and that slowing down is seen by us as the Cerenkov radiation.
@Inti Cheveyo 21.84% take it or leave it
Well SL-1 had an explosion because the moderator removed the central control rod a bit fast. Ik it is a different design and ik it was a test reactor for small remote bases in the US but damn, explosion was so big that the moderator who was on the reactor lid literally got hanged on the roof of the building with a control rod. Search it up, really horrifying story.
Boss: "Is there a way to make the Cherenkov green to meet investor expectations?" ( ͡° ͜ʖ ͡°)

Uranium night lights anyone?
I've done dozens, maybe hundreds, of reactor startups. The last one was as exhilarating as the first.
When the reactor is activated, the deep blue color it gives off is really dope 😮💙
Cherenkov radiation is absolutely beautiful, and awe inspiring.
Maybe I just need to get out more.
Cherenkov radiation is also called „blue light“.
It is not harmful, isn't it
@@allaeddinelkd9490 , it's utterly deadly.
@@inverse2k1 No it isn't! X-Ray and nearby alpha would kill you, but not blue light. Blue light is soft and kicks you like a drug, until x-ray starts hitting through really badly.

You are Welcome
I had the opportunity to visit a nuclear reactor back in october and i was able to see the cherenkov effect in the flesh , it was one of the most beautiful things ive ever seen
01:08 How all startups should sound so your stomach sinks and warns you of impending doom.
tfw you watch chernobyl then youtube recommends this
Yep same
it knows everything
I guess we are all here, because of that
Sameee wtf !?!?!?!
WTF GOOGLE STOP SPYING ON ME!!! D:
Not sure if someone else explained this, so here I go. First, all 5 videos of reactor startups are at various US reseach reactors. 4 of 5 of the videos are, as you can tell, for reactor pulses. The reactor is brought to just being subcritical by pulling all but one control rod. This last control rod can be shot out of the core to give a shot of reactivity resulting in the reactor to go prompt critical with the resulting blue flash. The reason it is only a flash is the nuclear fuel is designed in such a way that such a rapid event causes the fuel to heat up, expand just enough to leak more neutrons than needed to keep the reaction going, shuts itself down, and the operators reinsert all control rods to go back to a completely subcritical condition. Such a pulse is useful in it gives various material and nuclear experimentalists a large number of neutrons to study prperties of matter and chemical reactions on very small time scales. I believe Oregon State University used neutron burst like this to film the combustion process in a motorcycle engine.
Thank you for the explanation. I was quite curious about it and your explanation answered all of my questions.
Actually the first reactor is from slovenia, not the US.
Does not make sense because in the first video you can clearly hear a slavic language used for the countdown.
Look at me I'm from the us and the whole world spins around us.
... Bruh the first one is former Soviet .
Nothing American about it
I used to make the endcaps for nuclear reactors on a swiss cnc lathe. Definitely interesting but boring to make for sure! I've made well over 300,000 endcaps.

I've been lucky enough to see that glow in real life, it's truly mesmerizing!!!! 😲
The only true reactor startup is number 4, all of the others are reactor pulses. It even says on the last one. The reactor is running at low power, then the control rods are yanked out super quickly and then they fall back in. This causes a jump in power resulting in the blue flash! :)
yall cant fool me on the second video. I know the tesseract when I see it
Creative, I dig it
The lights are beautiful but chernobyl and fukushima had fireworks..
@Dominic Romani i was saying the blasts that busted the reactors at both power plants.
@Dominic Romani in fukushima 3 reactors been blown up
Lmao
@@someprick7053 No. Not at all.
At Chernobyl the reactor itself busted due to a steam explosion, the containment building then exploded due to hydrogen.
At Fukishima NONE OF THE REACTORS exploded. Only the containment buildings exploded.
FYI a containment building isn't to stop radiation, it's to protect the actual core from the elements and more extreme things like plane crashes etc.

Number 5 is the best one out all of them
I think nuclear energy is absolutely amazing and it really should be a big part of future energy plans more than it is now.
We should use a combination of nuclear, loads or solar, wind, hydro, geo and bio in combination with battery based storage to get away from oil, coal, gas etc.
I think a good idea would be to only construct nuclear plants in areas of the world that have a low risk of earthquakes, volcanic eruptions, tsunamis etc and every country should come to some kind of agreement to only build one type of plant that is highly reliable and low risk with a proven track record.
Right now we have a mix of plants with some of them being massively old and built in areas subject to natural disasters which puts risk through the roof.
Also a huge part would be to replace everything with a bad energy rating eg in the EU anything below a grade b/c for grade a/a+/a++ etc as it would save tons of energy.
I replaced every light bulb in our house a few years ago which was all very low rated old style bulbs numbering about 80 in total for grade a+ LED lights and our electricity bills dropped massively, we’re talking about an 85% saving on lighting, the house is still as bright if not brighter, I’ve only had the odd one or two bulbs die as we used high quality Philips bulbs almost everywhere and only the Chinese bulbs died and everywhere is cooler without the extra heat from the old bulbs.
Also we replaced any appliances that died with only grade a energy efficient products and that saved loads of energy.
Last year we installed a 6KW solar array on the roof which produces massive amounts of power, in the summer we can pull in 45KW some days, and even on the worst days in winter with completely cloudy sky’s we can cover a big chunk of our electricity needs.
Sorry to go on but I just think 100% renewable clean energy is easily in our grasp and we should get it done worldwide.
Definitely
Drop wind, keep solar and hydro/geothermal, keep gas for cars, and switch to nuclear fission and potentially in the future fusion for energy production.
Gas powered cars make up a very small % of hydrocarbons in our atmosphere compared to coal power plants in China and oil plants in America.
@@marciimeris503 thats an shitty idea. all cars will still produce too much co2 emissions when switching to gas for fuel. Fossil Fuels are dead and at somepoint they will be gone anyway and what are you going to do then? Go back to stick and stones? Fossil fuels did their jobs but we need to move on. Maybe stick to nuclear plants until renewable Power Sources have been constructed. We have to rethink our relation with cars anyway. The future will be Trains and Buses if we want to stop climate change. If we keep up our wasteful and lavish lifestyle bc we have to drive 500m with our cars out of laziness, we are doomed. This dosent mean others aren't allowed to achieve our living standards rather this means that we stop so others can follow us.
@@cruzer0561 you realize that cars make up less than 10% of carbon emissions right? Cars do not produce alot. It's coal/oil plants and cow farming/the meat industry.
No one talks about that because that would actually hurt politicians wallets, even the democrats. They don't care if they force us to switch to ev's because they're rich and will just buy an EV.
Oil and coal power plants will still exist. You don't solve the leading cause of carbon emissions by banning gas cars. And what of the meat industry? That produces alot of carbon emissions. You willing to go vegan to lower carbon emissions? Stop blaming cars when they're not even half the issue.
There's a that China, a place where coal usage is unregulated, is the leading country for carbon emissions per capita. Because it's not cars.
@@cruzer0561 also you literally CANNOT stop climate change. Climate change has existed before humans. Every single ice age that we have documented proof of, has been a direct result of global climate change. I mean ice ages are literally climate change. They are all preceeded by global warming periods.
It would be better to prepare for it by improving infrastructure, reducing our reliance on the sun for farming, reducing our usage of coal and oil to heat our homes, reducing our deforestation of the planet.
Trees are a natural carbon filter and we're cutting them down at extraordinary rates.
There's a reason democrats are so hell bent on wind power. Because it is trash. Solar, hydro, nuclear. All more efficient, all cleaner. But they know wind won't work, so they can keep oil going for longer and longer. Making a profit until they die and it's become our problem.
You want to fix global warming. Evs aren't the answer simple as that. I'm not against evs as an idea and an option. But I'm against forcing people to use them. Especially with how inflated the prices are in every aspect of them. Repair prices? It's like comparing a Mac to a pc for parts repair. Running a 240 line so you can charge at home? That's a pain in the ass. They'll do it for you for like 5k.
BEST THING IS, until we drop reliance on coal and oil for power, electric vehicles will cause MORE carbon emissions. Because they need electricity to charge and electricity production is, as stated, the leading cause of carbon emissions.
So yea no, banning gas cars for evs won't solve a fucking thing.
WOW . . . simply WOW
WAOW!
The first one where the control rods are entered is so fascinating
Thought this was going to show me young companies getting into the field of Nuclear Reactors
I love the gamma ray interference its so powerful it screws with everything even a camera lens.
It's not screwing with the lens. It's affecting the CCD chip in the camera. Since high energy particles dump energy when they interact with things, them hitting the CCD releases energy which activates the pixels in the chip causing the static. The same thing happens to the SOHO spacecraft (sun observing) when a solar flare happens and it gets slammed by the wave of gamma and xrays.
When i watched too many videos of chernobyl youtube recommended me this video
Scary to think the amount of energy that is being produced every second right there. Yet that energy is being used so efficiently.
Number 4 was fascinating to watch. 👍
Es terrorifico😎
That Cherenkov radiation is fascinating
Graphite : exist
Dyatlov : I've never met this guy !!
Stressful but soooo satisfying
I feel like this would be way more cool if i could fully understand what is going on threw all the start up stages and why they happen
Justin duke so that big box in the water is the uranium fuel pellets stacked into a bunch of rods. There are control rods that are placed in between the fuel rods that prevent a reaction from occurring. To start the reactor, they lift the control rods up. To shut it down, they lower the control rods back in. They don't have to remove the control rods completely and they can change how much power the reactor puts out by varying how much the control rods are inserted. Hope this helps
Nicksperiments you are correct, and chernobyl had a MINOR nuclear meltdown because they removed too much coolant and took out a few rods to test the emergency coolant, it worked, but not well enough and the reactor had a meltdown
tanklord99 da boss, as are you sir. The accident at Chernobyl was caused by an ill planned test where onsite power was completely lost. The reactor began to surge and there was a power spike which exposed the graphite moderated core causing it to ignite. As a result the water in the reactor caused a steam explosion which and the open graphite fire. Updrafts caused plumes of fission products. The reactors in Chernobyl were Russian built RBMK-1000 which were designed in the 1950s and were very unstable when operated outside their operating parameters which is exactly what happened in 1986 in Pripyat.
Its easier to look up the word cherenkov radiation and there are videos on the blue light.
tanklord99 da boss Chernobyl had a total meltdown. None of the fuel is in the reactor anymore. Lookup the “elephants foot”.
The RBMK reactor had a design flaw. When they ran the test (a test to see if they lost power, if the remaining thermal energy in the reactors core was sufficient to run the turbines long enough to operate the cooling pumps) the reactors became unstable. The flaw with the reactor was the graphite tips on the control rods causing a prompt criticality when I served quickly. So when they initiated the emergency shutdown, they had a prompt critically and a resulting steam explosion.
And Fukushima was MUCH worse.... and still is an on going issue.

IDKY, but this made me chuckle.
Phoenix Artice made me kinda laugh
This is terrifying on a whole 'nother level. I kid you not, almost backed out from watching it 😂
My question: These are not active reactors, they are training reactors. Like how is the steam produced absorbed? I can't see that glass container separating the water on all of the reactors. Because if you would breathe that steam you're likely poisoned
All of those but one was an excursion test. Anything but normal reactor starts.
Doug Elick I noticed that only one had the slow onset that I would expect from a startup. So the others were currently fissioning and showed a large shift in power output? Knowing what I do about nuclear power generation, I’m surprised such large shifts in power can occur so quickly. I did not know a control rod change could take place that quickly.
Those crackbrained comments about 3.6 Roentgens in every Cherenkov radiation video **eye-rolling**
Yeah but it took the HBO special 30 years to stop people saying 1.21 gigawatts every time they saw something like this. Its a nice change :P
So pleasing to observe as my favourite colour is electric blue!!!
Nuclear power is incredible , one of humans greatest achievements
It's like we're asking the universe to borrow a fraction of it's almighty power !
I'd like to be there again. That light is magic. It casts no shadow. As I closed my eyes it was everywhere, even in me
Of course you don't need water for the blue light, it's cherenkov radiation, the water is for safety purposes
Love the Cherenkov light
The last one was quite scary as we can clearly see and hear the eerie effects of the massive amounts of deadly gamma rays (and possibly the neutrons as well) interacting with the components of the camera! That perfectly explains the horrible deaths of criticality incidents throughout history!
To think that’s the same exact blue Cherenkov glow that victims of fatal Criticality incidents such as Hisashi Ouchi also saw is also quite eerie!
I would like to clarify that these aren't showing reactor startups so much as reactor pulses. Startups are much less exciting
Here we go with the Chernobyl quotes.
Hey, I have one question about radiation, why the people, and the cameras in the reactor doesn't die literally for the radiation? And why's the reactor pool is open?
I'm a mechanical engineering student so I know a little general info on this. Those reactors are extremely well contained and controlled. The water is absorbing A LOT of the radiation there. It is not safe for humans to enter the pools of water, the cameras you see here are being lowered down via pulleys or robotic arms. Liquid water makes an excellent radiation blocker and they made sure the reactors are submerged in more than enough, they are actually way deeper than they appear, usually at least 30ft down. On top of that there is some shielding around the reactors and the control rods are keeping the reactions under control. Unlike Chernobyl these control rods are pure, total neutron blockers, there are no graphite tips that could accelerate the reaction. It is safe to watch the reactor from above the pool because the amount of radiation that gets that far is only slightly above normal background radiation, you would have to be exposed constantly for years to get any risk. The big problems like Chernobyl, Fukushima, and 3 mile island happened because the reactors got too hot and there was not enough water. The water vaporized into steam, unlike liquid water, steam does not stop radiation, instead it carries radioactive material into the air. As long as the reactor temp is under control and you have enough coolant it remains safe. That's part of the reason Fukushima did not get anywhere near as bad as Chernobyl, they stopped the meltdown by practically dumping the ocean on it as a final fail-safe. Most of the radiation that escaped was then diluted across the entire Pacific by nearby currents and spread so thin and weak that it ceased to be dangerous. That is a major reason why most Japanese nuclear plants and so many other plants around the world are near the sea, to have access to virtually infinite coolant. Most plants now keep a massive factor of safety, even if the reactor exceeded 10x the standard operating power they usually have enough coolant and safety measures to force it to shut down. Fukushima only failed because their safety measures got destroyed and overwhelmed by the massive earthquake and tsunami. That is reassuring, it takes a literal act of God to force a modern, well-maintained reactor into a meltdown.
@@tristanfaulkner6003 Thanks!
*everybody gangsta till the control rods start jumping up and down*
This is beautiful yet so scary knowing what happened at Chernobyl
Chernobyl was said to be poorly maintained and engineered. The chance of it happening again is very minimum
@@bigbear5767 good point! I guess the scary part is knowing that once it goes wrong it's fucked for ever.
Somehow it is fascinating
Lol, what do you mean somehow? Scientists and engineers putting theory about the fundamentals of physics into practice and controlling operations that happen in millionths of seconds... this is AMAZING!
I already feel my eyes irradiating by such beauty
Man i Love this Blue glow
If you want to see more its cherenkov radiation
That power down sound at 2:10 is so cool
The first one looked like an immediate scram.
How sick would it look if we perfected nuclear Fusion. Literally our own pet star.
Those types of pools are giving me the creeps.
Gordon Freeman would like this video
Milton too.
