As others have stated, the reactor cannot explode like an atomic bomb. If it were as easy to make an atomic bomb as amassing a sufficient quantity of enriched uranium and bringing it together then any country that could obtain that material could make an atomic bomb. It doesn't work that way. It requires sophisticated technology and sufficient fuel to make an atomic bomb.
Regardless, that thing blowing up miles from a NATO base would stir up some bee hives. Out of curiosity how big of an explosion could one of these produce? Nuclear power plant failure levels? Or less of an explosion?
Basically when any reactor melts down. The fuel (nuclear material) melts and then breaches the containment vessel. When it does it flash boils the water causing extreme pressure, the neutron release can break the bonds of water into hydrogen and oxygen adding to the explosion. But unlike a fusion or fission bomb there isn’t enough chain reaction to detonate. They are good at spreading radioactive material though.

Yep, it could become a horrible dangerous mess, but unless the fuel was about 10 times more enriched than it needed to be for a subs reactor that won't happen. and even then a melted reactor won't explode in a nuclear explosion at worst it would be like Chernobyl but smaller, and more remote from humans.

Bottom of Kara Sea is probably the best place for them. They have unlimited cooling and the actinides can gradually decay to background levels. 30,000 years to reach 50% radioactivity is a long time, but its nothing on the geological scale.

Reactors meltdown, hydrogen may explode (chemical reaction) but no nuclear fission or fusion explosion will occur. There is a vast difference between the design of a bomb or a reactor and both are intentionally engineered to do different things and are not interchangeable no matter how hard you try...
@@redsun9261 they aren't intentionally engineered to do so. That was my point. A reactor will do as such, while a nuclear weapon consumes the radioactive material far more efficiently and the area is habitable within a few months with minimal side effects.
@@redsun9261 good luck blowing up something encased in a metre thick, steel reinforced, armoured concrete casket designed to resist impacts from jet airliners.
No reactor is going to turn into a fission bomb, their fuel is far too impure for that. It feels like you’re heading into clickbait territory like a bad History channel show.
Those brave men faced death, but they did it anyway. A Russian hero. a man will lay down his life for his brother. Nuclear radiation death is the worst way to die in my book.
K-19’s reactor has been under water for decades , so the chance of a nuclear melt down is low as the reactor is flooded with sea water. Also there wouldn’t be a nuclear explosion as the Uranium within the warheads would be weaken after decades of exposer to sea water.
Interestingly, the XO on the K-19 was almost certainly the sole man that prevented WW3 a year later during the Cuban Missile Crisis when he refused to authorize the launch of a nuclear tipped torpedo at an American warship.
I’m sure it has been commented here but a nuclear fission reactor CANNOT turn into a Nuclear Fission Bomb. The Uranium-235 used in the fuel rods are only enriched to about 40%, which is not anywhere near enough to trigger the kind of runaway criticality incident, nor are reactors configured in a way that would cause a nuclear explosion. What would happen is, thermal runaway that would cause a reactor meltdown that could cause a reactor explosion, either due to a steam explosion and or a hydrogen explosion that would kind of act like a very dirty nuclear bomb. Spreading radiation, similarly to how the Chernobyl nuclear disaster did, as that was an uncontained reactor failure/ explosion where the runaway heat causes a steam or hydrogen explosion that would spread radiation and the fuel rods would them melt into molten lava like substance, something referred to as corium.
The click bait titles are not doing the channel justice. I think I can speak for all regular viewers that we’d prefer to see better ones. We’re here for good content. Not click bait.
That's not what was meant, the radiation leak had the same effect as the radiation from the Atomic bomb dropped on Hiroshima did on the people of the Town, that bomb had low yield radiation that was designed to kill as many people as possible from radiation poisoning (ignore the people who died during the Blast when the Atomic bomb exploded for the purposes of the explanation because that's what is confusing everyone) over the following years and as did the radiation poisoning aboard the K-19, now after a lot of decontamination Hiroshima is habitable again with regular health checks to make sure that there isn't any radiation hot-spots
@lospolloshermanos5659 reactors cannot under any circumstance detonate like a nuclear bomb. They have completely different conditions inside them and the fuel is not nearly enriched enough to lead to a nuclear explosion. A meltdown leads to the reactor core melting into a lump of heated radioactive slag, plus maybe a hydrogen detonation that cannot damage the containment building

This guy’s video are normally spot on so I’m just busting balls a little, “ the North Atlantic,” shows map of pacific than goes from 1992 and says than in 1990 haha just giving you a hard time.

The Soviets were so amoral. Those men gave their life to avoid a war and they didn't even get the credit for it. Just go and forget what you have seen and done
I was a little kid in 1960, just about 6 years old. Where I grew up was fairly close to the U.S Navy Submarine Base -Groton and General Dynamics Electric Boat Shipyard. There were noticeable Naval Presents. It took a lot of work to work out the Nuclear Powered Submarines, We lost two in the 1960s. The Russians had it worst since the country operates on a level and mindset that would never fly here in the States or elsewhere with few exceptions in the world. They tend to "Make Do" is a good description for the Russians, they do lots of things well, but damn they have a tendency to do too many seats of the pants flying just so they can tell themselves we can keep up and match up you with an economy that comes up really short. While I have no love for the Soviet Union and what it stood for, the serving officers and enlisted men did have a degree of discipline and sense of duty that is sorely lacking today. K-19 was just one of the many missed steps, tragedies, and criminal behavior that plagued the Soviet Union from the start of the 1917 revolution. It seems the Russian Federation didn't learn anything either.
US reactors are designed to scram automatically. One of our subs was lost to this, leading to the ability to stop an automated scram. I'm unsure about Russian reactors though. They were damned careless about this stuff.
I can’t remember if it’s the same incident, but the lieutenant who went in to fix the reactor came back out 5 minutes later vomiting and turning red because he was hit with about 100 sieverts. That man actually holds the title of most irradiated person, not Ouchi
0:35. “Two years later in the N Atlantic “ dunno if anyone else noticed but the image/map is of the N pacific. That’s east coast of Russia and the western allusion islands. No big deal , just pointing it out haha..
what not many people know is that Anatoli Djatlov helped build the k19 and the nuclear reactor. During an accident, he received 200 rem (2 Sv), a dose that causes mild radiation sickness. and Djatlov was in charge of reactor 4 at the time of the Chernobyl Nuclear Disaster on April 26, 1986. so this man was a disaster to work with
A lady did not swing the champagne bottle. Instead, a captain third rank Panov swung the bottle. He was later demoted. A number of other details are in error. Your historical accuracy needs improvement. (per Wikipedia)
The voice over program used in these videos is getting more and more unreliable. It wasn't a soldering issue that caused the accident, it was a WELDING ISSUE that was the start of the incident.
I remember in my AP chem class, we actually watched this movie about the sub, and I could never for the life of me remember the name of that sub. Fascinating story that at the time, I honestly didn't believe was real.
a nuclear reactor can't be a nuclear bomb. Saying the opposite is physically incorrect. Percentage of enrichment of an average nuclear civil reactor is from 3 to 5%. In submarines, gets even higher for better control, going up to 20/25%, A nuclear bomb needs at leat 90% enriched fuel
I feel awful typing this but it’s the gods honest truth, unfortunately when I read the title of this video I had a hunch it was about Russia. And that’s not to belittle the Russian navy - The courage of these 22 sailors sacrifice Is second to none!
where is the ticking nuclear bomb part? @5:46 "A welder let hot solder drip into a cooling pipe..." welding and solder are not anywhere near being the same. What is your source for this stuff?
I don't know where you got your information, but there is no way a reactor core on a vessel of any kind could cause a nuclear explosion. The worst-case scenario would be a steam explosion causing environmental poisoning due to highly radioactive core fragments. A nuclear weapon is highly enriched, uranium compacted into physical dimensions that, when compressed further by conventional explosives causes a nuclear explosion. Those conditions don't exist in any heat-generating nuclear reactor. BTW, the USS Gato (SSN 615), is pronounced Gay Toe, not Gah Toe. I was stationed on the Gato from 1977 - 1980.
Great story. Well presented in this short doc. Saw the Kathryn Bigelow film too. And the obsessive cherry on the overly thorough cheeseburger, I even read the book. I couldn't finish watching the piece, because my genitals started itching, just like they do when I drive past the Pickering Nuclear Station. That's a complement, BTW.
Need a follow up on the Kara sea. With multiple "dumps" well call it. I'm just a tad concerned about the effects on anything from that area. The Simpsons 3-eyed fish comes to.ind but I know it's not just that simple.
Nuclear reactors on subs are too small to make any kind of spectacular explosion. Worst case scenario with extraordinary incompetence from the crew the reactor would melt down badly, leaving the sub dead in the water. Catastrophic explosion of a submarine nuclear reactor is extremely unlikely. In fact, so unlikely the Three Mile Island meltdown was partially caused by the fact the crew controlling it was an ex sub crew. And these people simply didn't consider such a thing as meltdown even a thing as residual heat from reaction in a sub reactor is small enough to be contained by a simple shutdown. Not so for a full sized distribution reactor.
Alvin Weinburg, who designed the US submarine PWRs, always said it was not appropriate to upscale these reactors. They are super safe at around 20 megawatts, but utility sized units have all sorts of (potential) problems with cooling especially with decay heat. That's why he advocated molten salt for utility scale plants and got told to shut up by his superiors. TMI proved him right.
The other thing is a sub or for that matter an carrier reactor is surrounded by cooling water. Commercial reactors are not and lack of cooling water is what caused all 3 commercial disasters.
Russian Sub Cmdr: Sir! Reporting fatal manufacturing flaws & catastrophic computational errors, sir! High Russian Official: Did I hear you say your family was moving to Siberia this winter, comrade? Russian Sub Cmdr: Sir! All testing is complete with highest marks! All is combat ready & capable, sir! High Russian Official: Yes, that's what I thought you said the first time, comrade. Set sail!
Creating a hydrogen/steam explosion wouldn't be too difficult for a reactor meltdown. Remember it was steam pressure in the reactor core that caused the structural failure at chernobyl. Imagine a meltdown in a sub boring through the hull and hitting cold sea water. The explosion would've been catastrophic. Not thermonuclear bomb level of destruction but the damage would be severe nevertheless. Add into the fact that the K19 had nuclear warheads onboard in the form of her missiles and it's even worse. While most safety systems would prevent an accidental arming and detonation of a nuke even we Americans had issues with safety systems failing under severe circumstances. If the shock of the steam explosion damaged the warheads they could IN THEORY go off and that would be detrimental for all the world to say the least considering where K19 was when her cooling system failed. Let's all agree to call this a nuclear near miss and pray that we as a species never come this close to bringing about our own Armageddon ever again.
It is true that a nuclear bomb is not the same as a nuclear meltdown. However, nuclear meltdowns can still be a huge problem. Remember Chernobyl? That was not a bomb. It is still a highly radioactive zone to this day. Obviously, a submarine reactor has less nuclear fuel than a reactor like Chernobyl... The submarine melting down in close proximity to NATO assets is absolutely a cause for concern. At that time, NATO and the USSR were constantly looking for reasons to attack each other. Those volunteers sacrificed their lives so that peace was more likely. They made that decision knowing that nobody would give them credit and they could never speak about the event even if they lived. Those are the kinds of people that created the relative peace we get to enjoy today. Take some time to appreciate them.
I fail to see how a meltdown of a reactor would be more extensive then the nuke bombs of WW2. Chernobal wasn't nor any other reactor explosion. An explosion yes but not like a nuke.
There is no equivalence between an uncooled nuclear reactor and a "nuclear bomb". They work so differently that you couldn't create a nuclear explosion if you wanted to. Even the nuclear missiles on board could not be exploded this way. However, you would get a steam explosion.
"Now on the verge of turning into a nuclear bomb!" I'm not a nuclear physicist but it's my understanding that while a reactor can certainly explode, a reactor is not and can not be a nuclear bomb not even if you wanted to. Also Nuclear gasses??? I often enjoy this channel's content, but I get a little prickly when people talk about Nuclear reactors in this way because it leads the less knowledgeable people to the wrong conclusions, and in turn those conclusions lead to bad policy from government.
Been a fan since well before the text-only days and I have to say that in recent months you have been seemingly going the route of click bait and disingenuous titles, please don’t take that path as you’re one of very few remaining high quality list/doco channels.
If it was to explode no matter the strength of the explosion it would still disperse nuclear material though technically making it a ",nuclear bomb" or a dirty bomb?
Just like other commenters have observed the nuclear reactor on the K-19 submarine would not and can not explode like a thermonuclear bomb. However it could meltdown, and have a localized steam explosion that would have destroyed the submarine and killed everyone on board. Also the radioactive waste and fallout of the reactor would pollute the ocean with radioactive fallout.
A nuclear reactor will not explode like a nuclear bomb because they are different designs. A reactor can overheat and explode but it's a steam pressure explosion not an atomic explosion.
Well it ran for around 30 years. That's about average for ships and subs tech and safety life expectancy. And long for a boat with that many issues. Submariners are a super special group anyway. No matter the power source, every deep dive could be it's last. But whether battery acid fumes or radiation leak from a reactor. Hazardous materials from either can be detrimental for a crew. Dedicated and brave is all I can say about submariners.
The only way the sub could explode in a nuclear explosion is if the war heads detonated. The reactor would melt right through the bottom of the sub if it went in to melt down, I suppose the resulting hydrogen explosion would destroy the sub which it could in theory set off one of the nuke missals, but I think it unlikely
Wouldn’t inserting the control rods stop the nuclear reaction and stop the heating of the water? Or are they just to cool and said fuck it they aren’t needed
As already pointed out ad nauseum, a nuclear meltdown doesn't lead to a nuclear explosion. An explosion may occur from the gases produced by the nuclear reaction. But even if this occurs in close vicinity of a nuclear tipped ballistic missile onboard the submarine, it still has absolutely no chance of causing a nuclear explosion. My mind is blown that in this day and age where this could be clarified in half a minute by swiping one's literal fingertips on google, somebody would parade their ignorance so blatantly and base an entire video on it. The sad part is that the story, devoid of any exaggeration is still a very interesting one!
What happened at Fukushima and Chernobyl, is the top of the reactor vessel was blown off by exploding hydrogen gas. I suspect the process of nuclear energy, to be a special kind of electrolysis. You have a vessel filled with water, radio-active metal rods in that vessel, arranged in a certain position. Then an electric current is sent through these rods, they heat up, and hydrogen and oxygen from the water is being separated. This is free energy, because water is the fuel. The rods are being "used up" as well, that is why they have to be replaced after 20 years of service. What you get is oxygen for the crew, and hydrogen for propulsion. Even the ancient Egyptians knew this proces. I don't know where they dump all this excess hydrogen gas, which is a considerable amount, so most likely they burn it, and propel the boat in this way. All the stories about a threat to the planet are urban legends. A submarine can be traced by the radioactive signature that she leaves in the water, but it might as well be a heat signature, because this reactor needs cooling. The water for that cooling system is dumped back in the ocean. That is why subs leave a heat signature in the water. They produce more noise, then diesel-electric boats, because of the steam pipes and valves. They are much faster, can dive deeper, and can stay under water indefinitely, that's what makes them a dangerous opponent. But they are easier to find.
Way off base. The hydrogen is generated by the Zirconium in the fuel cladding stripping the Hydrogen from the surrounding steam when the temperature of the fuel reaches about 1200C. No electricity involved...it is totally a catalyzed high-temperature chemical reaction. At the time that "used fuel" is pulled from the reactor, only about 5% of the original Uranium fuel has actually undergone fission, far from "used up". What happens is that certain by-products of the fission reaction accumulate to the point where a chain reaction becomes difficult to impossible to sustain. Civilian reactors are generally partially-refueled annually, with about half the load being replaced and the rest re-arranged. 20 years before refueling is on the high side even for a Naval Reactor, a totally different design with a totally different fuel composition. Unless there is serious damage to the plant, a nuclear sub does NOT leave a "Radioactive signature". Cooling is performed by running the Reactor Cooling Loop through a heat exchanger cooled by seawater. The only Hydrogen generated by a nuclear submarine IS the result of electrical hydrolysis of water, but it is a by -product of the oxygen-generating system to produce a breathable atmosphere, NOT the reactor. Said Hydrogen is compressed to the point where it can be discharged to the sea. Up to a certain power level, most sub reactors can be cooled by convective circulation with no pumps required. Noise isolation techniques make a modern nuke sub quieter than a modern Diesel-Electric sub.
@@joni3503 Not if released over time in small quantities. The hydrogen is compressed in order to allow it to be discharged against the water pressure. We're not storing it to dump all at once. At 1000 feet depth, the pressure on the hull is around 432 PSI, so you would need to compress the Hydrogen to that pressure for it to just slowly bubble out. 3 things give away the position of a sub: NOISE- The biggest risk HEAT - Not generally an issue due to movement and depth. MAGNETIC: The large metallic mass of the sub will distort the Earth's magnetic field, but the disruption is so small that is nearly impossible to detect if the sub is deep.
@@kevincrosby1760 Maybe that is still possible at 1000 feet, but any deeper would become difficult. Hydrogen is highly inflammable, can it explode when compressed?
@@joni3503 1000 feet depth is nothing for a modern submarine. Open literature suggests the normal max operating depth of a Los Angeles-class submarine is around 1500 feet, with a maximum operating depth of 2250-3000 feet. Any time something appears in the open literature (like the internet) regarding the capabilities of a US Navy vessel, it is most likely based on info provided by the US Navy. The USN is famous for releasing numbers much smaller than the actual limit. For example, the ship I was on had an official published top speed of 21 knots. We regularly CRUISED close to that, and could go faster if needed. Ever see a 400-foot USN warship pull the bow out of the water, settle out on a nice plane, and leave sporting a roostertail behind it like a speedboat? I have, several times. A Hydrogen explosion requires Oxygen.
I don't care what country they are from. The men who volunteered to entered that reactor room should be considered heros

There is a vast difference between the design of a bomb or a reactor and both are intentionally engineered to do different things and are not interchangeable no matter how hard you try...

A reactor is intentionally engineered to leave the land uninhabitable for centuries? Kinda silly comment there.
@@R0me0316 you can contaminate the land for centuries just blowing up pile of the nuclear waste. Do need reactor for that. Your comment is silly.

K-19’s reactor has been under water for decades , so the chance of a nuclear melt down is low as the reactor is flooded with sea water. Also there wouldn’t be a nuclear explosion as the Uranium within the warheads would be weaken after decades of exposer to sea water.

I’m sure it has been commented here but a nuclear fission reactor CANNOT turn into a Nuclear Fission Bomb. The Uranium-235 used in the fuel rods are only enriched to about 40%, which is not anywhere near enough to trigger the kind of runaway criticality incident, nor are reactors configured in a way that would cause a nuclear explosion. What would happen is, thermal runaway that would cause a reactor meltdown that could cause a reactor explosion, either due to a steam explosion and or a hydrogen explosion that would kind of act like a very dirty nuclear bomb. Spreading radiation, similarly to how the Chernobyl nuclear disaster did, as that was an uncontained reactor failure/ explosion where the runaway heat causes a steam or hydrogen explosion that would spread radiation and the fuel rods would them melt into molten lava like substance, something referred to as corium.
@@L33tSkE3t not sure about this specific model of submarine but the western ones use reactors fueled by 93-97% enriched uranium.

"Turn into a nuclear bomb"
That's... not how reactor meltdowns work.
That's not what was meant, the radiation leak had the same effect as the radiation from the Atomic bomb dropped on Hiroshima did on the people of the Town, that bomb had low yield radiation that was designed to kill as many people as possible from radiation poisoning (ignore the people who died during the Blast when the Atomic bomb exploded for the purposes of the explanation because that's what is confusing everyone) over the following years and as did the radiation poisoning aboard the K-19, now after a lot of decontamination Hiroshima is habitable again with regular health checks to make sure that there isn't any radiation hot-spots
i don't think anybody on board the ship would care about the physics when it blows up
that's exactly how they work
@lospolloshermanos5659 reactors cannot under any circumstance detonate like a nuclear bomb. They have completely different conditions inside them and the fuel is not nearly enriched enough to lead to a nuclear explosion. A meltdown leads to the reactor core melting into a lump of heated radioactive slag, plus maybe a hydrogen detonation that cannot damage the containment building
They were definitely the most elite crew. So many of them gave there live to stop a war from happening. That's pretty elite
Ok. Nuclear meltdowns aren’t like a bomb going off.

Man those were some brave souls that volunteered to enter the reactor chamber
I was a little kid in 1960, just about 6 years old. Where I grew up was fairly close to the U.S Navy Submarine Base -Groton and General Dynamics Electric Boat Shipyard. There were noticeable Naval Presents. It took a lot of work to work out the Nuclear Powered Submarines, We lost two in the 1960s. The Russians had it worst since the country operates on a level and mindset that would never fly here in the States or elsewhere with few exceptions in the world. They tend to "Make Do" is a good description for the Russians, they do lots of things well, but damn they have a tendency to do too many seats of the pants flying just so they can tell themselves we can keep up and match up you with an economy that comes up really short. While I have no love for the Soviet Union and what it stood for, the serving officers and enlisted men did have a degree of discipline and sense of duty that is sorely lacking today. K-19 was just one of the many missed steps, tragedies, and criminal behavior that plagued the Soviet Union from the start of the 1917 revolution. It seems the Russian Federation didn't learn anything either.
Putin longs for a return to those days and we are witnessing the result.
A nuclear meltdown is nothing like a nuclear bomb...
The Widow Maker.. The Kursk could have been another disaster as well had the crew not shut down the reactors before they all died.
US reactors are designed to scram automatically. One of our subs was lost to this, leading to the ability to stop an automated scram.

Wow that is so sad. Good moive as well. Nice video.
You don't know how nuclear reactors or nuclear bombs work. A reactor cannot create a nuclear explosion to suggest that is ignorant.
a nuclear reactor can't be a nuclear bomb. Saying the opposite is physically incorrect. Percentage of enrichment of an average nuclear civil reactor is from 3 to 5%. In submarines, gets even higher for better control, going up to 20/25%, A nuclear bomb needs at leat 90% enriched fuel
I LOVE DIS GUY MODE OF SPEAK

I don't know where you got your information, but there is no way a reactor core on a vessel of any kind could cause a nuclear explosion. The worst-case scenario would be a steam explosion causing environmental poisoning due to highly radioactive core fragments. A nuclear weapon is highly enriched, uranium compacted into physical dimensions that, when compressed further by conventional explosives causes a nuclear explosion. Those conditions don't exist in any heat-generating nuclear reactor. BTW, the USS Gato (SSN 615), is pronounced Gay Toe, not Gah Toe. I was stationed on the Gato from 1977 - 1980.

Sailors moron no soldiers.
Nuclear reactors on subs are too small to make any kind of spectacular explosion. Worst case scenario with extraordinary incompetence from the crew the reactor would melt down badly, leaving the sub dead in the water. Catastrophic explosion of a submarine nuclear reactor is extremely unlikely. In fact, so unlikely the Three Mile Island meltdown was partially caused by the fact the crew controlling it was an ex sub crew. And these people simply didn't consider such a thing as meltdown even a thing as residual heat from reaction in a sub reactor is small enough to be contained by a simple shutdown. Not so for a full sized distribution reactor.
Alvin Weinburg, who designed the US submarine PWRs, always said it was not appropriate to upscale these reactors. They are super safe at around 20 megawatts, but utility sized units have all sorts of (potential) problems with cooling especially with decay heat. That's why he advocated molten salt for utility scale plants and got told to shut up by his superiors. TMI proved him right.
The other thing is a sub or for that matter an carrier reactor is surrounded by cooling water. Commercial reactors are not and lack of cooling water is what caused all 3 commercial disasters.
Ah yes yet another fine example of Soviet nuclear technology being sound and safe

Creating a hydrogen/steam explosion wouldn't be too difficult for a reactor meltdown. Remember it was steam pressure in the reactor core that caused the structural failure at chernobyl. Imagine a meltdown in a sub boring through the hull and hitting cold sea water. The explosion would've been catastrophic. Not thermonuclear bomb level of destruction but the damage would be severe nevertheless. Add into the fact that the K19 had nuclear warheads onboard in the form of her missiles and it's even worse. While most safety systems would prevent an accidental arming and detonation of a nuke even we Americans had issues with safety systems failing under severe circumstances. If the shock of the steam explosion damaged the warheads they could IN THEORY go off and that would be detrimental for all the world to say the least considering where K19 was when her cooling system failed. Let's all agree to call this a nuclear near miss and pray that we as a species never come this close to bringing about our own Armageddon ever again.
"And in 1992 the submarine secured her reputation and nickname of Hiroshima, then in 1990"
Wait, this sub could time travel???
It is true that a nuclear bomb is not the same as a nuclear meltdown. However, nuclear meltdowns can still be a huge problem. Remember Chernobyl? That was not a bomb. It is still a highly radioactive zone to this day. Obviously, a submarine reactor has less nuclear fuel than a reactor like Chernobyl...
The submarine melting down in close proximity to NATO assets is absolutely a cause for concern. At that time, NATO and the USSR were constantly looking for reasons to attack each other. Those volunteers sacrificed their lives so that peace was more likely. They made that decision knowing that nobody would give them credit and they could never speak about the event even if they lived. Those are the kinds of people that created the relative peace we get to enjoy today. Take some time to appreciate them.
I fail to see how a meltdown of a reactor would be more extensive then the nuke bombs of WW2. Chernobal wasn't nor any other reactor explosion. An explosion yes but not like a nuke.
There is no equivalence between an uncooled nuclear reactor and a "nuclear bomb". They work so differently that you couldn't create a nuclear explosion if you wanted to. Even the nuclear missiles on board could not be exploded this way. However, you would get a steam explosion.
What's rodeo-active waste?

I often enjoy this channel's content, but I get a little prickly when people talk about Nuclear reactors in this way because it leads the less knowledgeable people to the wrong conclusions, and in turn those conclusions lead to bad policy from government.

If it was to explode no matter the strength of the explosion it would still disperse nuclear material though technically making it a ",nuclear bomb" or a dirty bomb?
Just like other commenters have observed the nuclear reactor on the K-19 submarine would not and can not explode like a thermonuclear bomb. However it could meltdown, and have a localized steam explosion that would have destroyed the submarine and killed everyone on board. Also the radioactive waste and fallout of the reactor would pollute the ocean with radioactive fallout.
@0:14 Submarine thrown overboard.....????
A nuclear reactor will not explode like a nuclear bomb because they are different designs. A reactor can overheat and explode but it's a steam pressure explosion not an atomic explosion.

Well it ran for around 30 years. That's about average for ships and subs tech and safety life expectancy. And long for a boat with that many issues. Submariners are a super special group anyway. No matter the power source, every deep dive could be it's last. But whether battery acid fumes or radiation leak from a reactor. Hazardous materials from either can be detrimental for a crew.
Dedicated and brave is all I can say about submariners.
Yes, submarine reactors don’t simply turn into nuclear bombs. That movie reality. Not “actual “ reality.
The only way the sub could explode in a nuclear explosion is if the war heads detonated. The reactor would melt right through the bottom of the sub if it went in to melt down, I suppose the resulting hydrogen explosion would destroy the sub which it could in theory set off one of the nuke missals, but I think it unlikely
Wouldn’t inserting the control rods stop the nuclear reaction and stop the heating of the water? Or are they just to cool and said fuck it they aren’t needed
As already pointed out ad nauseum, a nuclear meltdown doesn't lead to a nuclear explosion. An explosion may occur from the gases produced by the nuclear reaction. But even if this occurs in close vicinity of a nuclear tipped ballistic missile onboard the submarine, it still has absolutely no chance of causing a nuclear explosion.
My mind is blown that in this day and age where this could be clarified in half a minute by swiping one's literal fingertips on google, somebody would parade their ignorance so blatantly and base an entire video on it. The sad part is that the story, devoid of any exaggeration is still a very interesting one!
What happened at Fukushima and Chernobyl, is the top of the reactor vessel was blown off by exploding hydrogen gas. I suspect the process of nuclear energy, to be a special kind of electrolysis. You have a vessel filled with water, radio-active metal rods in that vessel, arranged in a certain position. Then an electric current is sent through these rods, they heat up, and hydrogen and oxygen from the water is being separated. This is free energy, because water is the fuel. The rods are being "used up" as well, that is why they have to be replaced after 20 years of service. What you get is oxygen for the crew, and hydrogen for propulsion. Even the ancient Egyptians knew this proces. I don't know where they dump all this excess hydrogen gas, which is a considerable amount, so most likely they burn it, and propel the boat in this way. All the stories about a threat to the planet are urban legends. A submarine can be traced by the radioactive signature that she leaves in the water, but it might as well be a heat signature, because this reactor needs cooling. The water for that cooling system is dumped back in the ocean. That is why subs leave a heat signature in the water. They produce more noise, then diesel-electric boats, because of the steam pipes and valves. They are much faster, can dive deeper, and can stay under water indefinitely, that's what makes them a dangerous opponent. But they are easier to find.
Way off base. The hydrogen is generated by the Zirconium in the fuel cladding stripping the Hydrogen from the surrounding steam when the temperature of the fuel reaches about 1200C. No electricity involved...it is totally a catalyzed high-temperature chemical reaction.
At the time that "used fuel" is pulled from the reactor, only about 5% of the original Uranium fuel has actually undergone fission, far from "used up". What happens is that certain by-products of the fission reaction accumulate to the point where a chain reaction becomes difficult to impossible to sustain.
Civilian reactors are generally partially-refueled annually, with about half the load being replaced and the rest re-arranged.
20 years before refueling is on the high side even for a Naval Reactor, a totally different design with a totally different fuel composition.
Unless there is serious damage to the plant, a nuclear sub does NOT leave a "Radioactive signature". Cooling is performed by running the Reactor Cooling Loop through a heat exchanger cooled by seawater.
The only Hydrogen generated by a nuclear submarine IS the result of electrical hydrolysis of water, but it is a by -product of the oxygen-generating system to produce a breathable atmosphere, NOT the reactor. Said Hydrogen is compressed to the point where it can be discharged to the sea.
Up to a certain power level, most sub reactors can be cooled by convective circulation with no pumps required. Noise isolation techniques make a modern nuke sub quieter than a modern Diesel-Electric sub.
@@kevincrosby1760 Will this compressed hydrogen being discharged into the sea not leave a trace behind the boat?
@@joni3503 Not if released over time in small quantities. The hydrogen is compressed in order to allow it to be discharged against the water pressure. We're not storing it to dump all at once. At 1000 feet depth, the pressure on the hull is around 432 PSI, so you would need to compress the Hydrogen to that pressure for it to just slowly bubble out.
3 things give away the position of a sub:
NOISE- The biggest risk
HEAT - Not generally an issue due to movement and depth.
MAGNETIC: The large metallic mass of the sub will distort the Earth's magnetic field, but the disruption is so small that is nearly impossible to detect if the sub is deep.
@@kevincrosby1760 Maybe that is still possible at 1000 feet, but any deeper would become difficult. Hydrogen is highly inflammable, can it explode when compressed?
@@joni3503
1000 feet depth is nothing for a modern submarine. Open literature suggests the normal max operating depth of a Los Angeles-class submarine is around 1500 feet, with a maximum operating depth of 2250-3000 feet.
Any time something appears in the open literature (like the internet) regarding the capabilities of a US Navy vessel, it is most likely based on info provided by the US Navy. The USN is famous for releasing numbers much smaller than the actual limit.
For example, the ship I was on had an official published top speed of 21 knots. We regularly CRUISED close to that, and could go faster if needed.
Ever see a 400-foot USN warship pull the bow out of the water, settle out on a nice plane, and leave sporting a roostertail behind it like a speedboat? I have, several times.
A Hydrogen explosion requires Oxygen.
