4:35 I’d suggest Oppenheimer was far from ‘delighted’ when he saw the explosion, given he quoted part of a text from Hindu scriptures: “Now I am become Death, the destroyer of worlds”. Further, he later went on to say “We knew the world would not be the same. A few people laughed, a few people cried, most people were silent.” Yup, definitely not ‘delighted’.

Misinformation/Errors: 1) Loss of coolant at the Hanford reactors would not have resulted in a “nuclear explosion”. That would’ve been physically impossible. A meltdown and possibly a steam explosion, yes-but NOT a nuclear explosion. 2) After the dropping of the 2nd bomb on Nagasaki, Japan did not immediately surrender. It almost took a third bomb. 3) Windscale was not the first serious accident, NRX was 4) Failure to mention the contribution to the risk of overheating by the improvised “solution” to a low neutron flux issue caused by addition of the neutron absorbing cartridges that were actually lithium isotope targets for the thermonuclear program. This rushed solution was the trimming of fuel element cooling fins enhance the neutron economy.

[@Hrojar]

No, tak to se mýlíte. V manuálu pro reaktor v Hanfordu je na straně 385 napsáno: přijde-li tento reaktor o vodu a zároveň budou vytaženy všechny řídící a regulační tyče, je riziko jaderného výbuchu více než reálné a radioaktivita se šíří divoce. Ten výbuch by nebyl nijak veliký (v Černobylu měl výtěžnost cca 500 tun TNT), neboť v okamžiku, kdy začne rozhoření na rychlých neutronech a započne neřízená reakce paliva, začnou působit obrovské odpudivé síly a palivo se vlivem vysokého žáru a těchto sil odpaří a rozletí do ovzduší. A tak se to i stalo v Černobylu, ač nejprve všichni papouškovali, jak reaktor drtil výbuch páry a vodíku. Ale jen do doby, než vědci položili otázku, kde jsou ty čtyři nádrže separátorů (každá délky 30 m, průměr 3 m a tloušťka materiálu ze speciální, nerezové oceli 64 mm). Oni se totiž totálně vypařili! Nenašli z nich ani zrnko té oceli a věřte, že na to nějakých 3000°C z výbuchu vodíku opravdu nestačí. To by možná tak opálilo barvu a nádržky by leželi někde v okolí zničeného reaktoru....

[@stewartmackay]

I'm from the far north coast of Scotland and we had/have a facility there, called Dounreay, where they were making plutonium under the guide of an experimental power station. We now know that during the 60s and 70s there were many radiation leaks. In fact there are a couple of beaches to this day that you are not allowed on, they have robots that go back & forth looking for radioactive particles. We also had large local leukemia clusters, including my own mother who died from it, but the UK gov't always said the clusters were not connected with Dounreay, but I just don't believe that. The plant is now being decommissioned, but the half life of the reactors is 50,000 years, so it looks like we're stuck with it.

[@Svensk7119]

@Gois83 Actually, the USSR didn't declare war on Japan until late-July, early-August 1945, so they wouldn't really have had a chance to surrender to Russia, before. The surrendering to the Soviets happened in August as Stalin moved tens and hundreds of thousands East to face the new fight. Imperial troops surrendered right about that time, because those were orders. Before, it was less than one percent of Japanese forces who surrendered. I think the Allies unitedly refused piecemeal surrender from Japan. I think the Soviets refused such an offer from Imperial Japan, if I recall correctly.

Can whoever makes these at least TRY to do basic research? As there's literally no situation where a nuclear reactor can explode like a nuclear bomb. The worst case which isn't even likely with the little weapon production reactors talked about here is a meltdown where the fuel goes into the basement and some radiation release. The reactor fire that this entire documentary is about is kinda of a good example, it's a shame no one working on the script seems to know about it.

[@karlsullivan4761]

Don't they mean the first "large-scale" nuclear accident?

@@Ismalith Fair enough. However, as I'm constantly reminding people, accurate language is important. Consider the following... A person says something is their "forte". The proper pronunciation will sound like "fort", because it is a french based word meaning strength or emphasis.

Therefore most or us in America are running around saying something is our "to play loudly", sounding like a bunch of idiots in front of Europeans....Is it any wonder they think we're stupid?

@@karlsullivan4761 Not technically correct, Forte in music means "Play strongly" not loudly, it has the same effect though but the word itself just means "Strongly" Which is the wrong tense for being someone's forte but we can attribute that to translation. Language is indeed important, in this case you're mixing the actual translation of the word with it's musical connotation, but even then when we train as musicians, the word pianissimo means very softly, not "play very softly" these words were marked on sheet music to describe the intensity to play but were not exclusive to music, even though most of those words are most commonly seen in that context. The etymology for both the Italian, and French Forte is from the Latin Fortis. (The only reason I know any of that is that I was trained as a musician Vocabulary was very important to that.) it is used commonly now to mean loud but the word actually does mean strong.

Again, around 810 you’re wrong. The fissile material would not have gone critical and created a nuclear explosion. It’s not the case, rather, it would have gone critical, expanded its energy and created what could be called a dirty bomb.

[@ExarchGaming]

it was a steam explosion, when it spiked it instantly vaporized all of the water in the core which was incredibly damaging, but yes it was in practicality a dirty bomb. as it flung radioactive dust and debrise far in to the sky, which got picked up by the wind currents. That's why they were able to detect it in belarus and sweden so quickly. You are mostly correct, it could not have gone prompt critical because that requires the fuel to be compressed down to the size of a ball point pen tip.

[@micnorton9487]

.. not exactly einstein, a dirty bomb is a regular explosive used to scatter radioactive materials,, a dud is a nuclear device that goes off without the proper arming procedure, detonating the chemical explosives and only partly fissioning the nuclear fuel... But if a fissionable Mass goes supercritical WITHOUT any other explosive fuel, which is extremely unlikely but it can happen,, like if a plutonium refinement didn't go exactly correct and there is a little bit of plutonium 240 in with the 239, this could make it spontaneously fission ... The energy released would be nowhere near the energy of an actual warhead,, somewhere in the hundreds of pounds to a few tons of TNT.. Wasn't the explosion at Chernobyl actually caused by hydrogen, with the fissile material just adding a tiny amount energy to the explosion,, making the explosion equivalent to about a dozen tons of TNT?

[@glenlongstreet7]

There are numerous reports of Nuclear Accidents here on KZbin. I am not sure which one was first. I reserve my comments. However, the 'Carbon Pile' reactor has a significant safety issue. It has to do with 'phase transformation' where the atomic structure of the carbon can suddenly change, causing damage to the fuel cell. It is similar to phase change in Iron where the atoms shift from 'body centered cubic' to 'face centered cubic', whatever those terms mean. The bottom line here is the atomic structure suddenly changes and so the dimensions of the carbon fuel cell changes, getting suddenly bigger or smaller. It is like cracking the block of a petroleum engine, only a lot worse. I might be wrong.

[@Thornus_______]

The aluminum cartridges were a terrible design anyone could tell you aluminum warps at high temperature

[@ExarchGaming]

at around 8:00 in there is a major accuracy error. A core meltdown does NOT cause an atomic explosion. despite how close the fuel is together, in order to cause them to go prompt critical requires focusing that ball of fissle material down to the size of a pin point, which is what the explosives do to cause the fissile explosion. It is impossible to create an atomic detonation by lack of coolant. The explosions at chernobyl and fukushima were caused by hydrogen and steam explosions. Where the heat from the core caused all of the water to vaporize at once and caused a massive (conventional) explosion that flung radioactive material extremely far as well as putting loads of radioactive dust in to the atmosphere. Fukushima was even less severe than that.

[@knutholt3486]

If the core melts down and gets concentrated, and furthermore is blended with material that works as moderator, the fission can run wild and either produce an explosion or a wild nuclear fire. In Chernobyl the fission ran wild and produced enough heat to make the system explode. This was not an explosion with the speed of an atomic bomb, but still an explosion partly produced by nuclear reactions running wild and partly by burning graphite.

[@ExarchGaming]

@@knutholt3486yes.... but the point is it was not a nuclear detonation. it was a steam explosion caused by an enormous amount of heat built up in the core in a very short period of time. Steam explosions are terrifying on their own, but it's not an atomic explosion either.

[@knutholt3486]

@Gaming When the heat that makes the explosion comes from a nuclear reaction that increases uncontrolledly, it is a nuclear explosion. The material around gets heated and explode together with the the nuclear material. But this is not any different from an atomic bomb where the greatest part of the explotion is in the air, water, soil or whatever surounds the bomb. In Chernobyl, garphite also burned and gave a contribution, so it was mixed. What basically happens is that most of the energy released from the nuclear reaction is transfered to the immediate surroundings that then explode. The energy is transfered partly from kinetic collition with atoms in the nuclear material, but even more from radiation that gets absorbed by the surrroundings.

[@ExarchGaming]

@@knutholt3486When I say a nuclear detonation, i'm refferring specifically to a prompt criticality caused explosion, where there are enough neutrons to cause a self sustaining reaction, which happens in microseconds. That is not what happened in chornobyl. what happened in chornobyl was supercriticality causing all of the water in the core to boil instantaniously and turn to steam. steam was the agent that caused the reactor vessel to rupture and explode. There was not enough U-235 in the fuel used in chornobyl to cause an atomic explosion. RBMK reactors used lightly enriched U-238 because it was as said in the tv series cheaper than the highly enriched fuel western nations used. (2 percent enrichment compared to 5 percent in say the US) For a nuclear detonation to occur the enrichment required is 80 percent or higher.

[@knutholt3486]

In Chernobyl the controle rods were pulled too far out and that caused an accellerating nuclear reaction wich of course also caused what you tell about. The result was a blended type of explosion. In Fukushima the lack of cooling caused the kernal to melt down which also caused an accelerating nuclear reaction but also the things you tell about. The effect at those two sites did not anount to an atonic bomb, however, because the melted core was not dense enough to make the explosion so intense. But the explosions were a at least partly nuclear because an accelerating nuclear reaction released much of the energy for the explosion. So yes, improper function or lack of coolant can cause an atomic detonation, but the physical effect will not be as great as in an atomic bomb, because the material is not dense enough for that.

I agree. However, I do appreciate the fact that people go to alot of effort to try and tell these stories to a wider audience than may be interested in some of the more "technical" explanations available on line. I wish a little more attention to historic and technical accuracy was paid, but then, that is true of most of what comes out of hollywood or other centres as 'biopic' or 'documentary'.

The first thermonuclear device tested in late 1952 by the U.S. was not, and I must repeat, WAS NOT an H-bomb, or a bomb at all. I wish that people who know best would stop calling it that. Correctly, it could be labelled as an underground mine such as those employed by the allies in the Somme in the first world war. Something which weighs tens of thousands of tones and needs thousands of horsepower just to keep itself cool is not a bomb. On that basis, the Soviets were first to test an hydrogen bomb with their layer cake design. Contrary to what some historians conveniently prefer to believe, the layer cake design, despite its yield limitations, was indeed a true H-bomb

Well maybe if the Britbongs weren't constantly letting card carrying communists like Klaus Fuchs into secret programs and leaking tech to the Soviets left and right, we could have trusted them. If it wasn't for the British vouching for Fuchs and the United States being foolish enough to trust them, the Soviets would not have gotten the bomb. Or at the very least, would not have gotten the bomb for substantially longer.

[@beardmonster8051]

It is far from certain that the Hiroshima and Nagasaki bombs were the cause of Japan's surrender. Soviet declared war and invaded Manchuria just before the second bomb dropped, and it is quite possible that this was a more compelling reason than the nuclear bombs.

[@rightlyso8507]

I highly doubt that the Soviets were even thinking of carrying out an invasion of the Japanese homeland, which would have ended the war. In fact, even after the atomic bombing of Hiroshima, the 59th Army (infantry) got a new commander in order to more closely coordinate operations as part of a defense effort by Japan to deter possible landings of Allied forces in the San'yo region of western Honshu.

[@beardmonster8051]

@@rightlyso8507 The way I've understood things, Japan wanted out of the war, but they didn't want to unconditionally surrender. The hope of having Soviet broker peace disappeared with the attack in Manchuria though, leaving only unconditional surrender as an option. Japan's big cities were already wrecked before the nuclear bombings, so there wasn't that much left to bomb. I'm not claiming to know the facts of the matter. But it's a debated topic, and not all agree that the nuclear bombs ended the war.

[@rightlyso8507]

@@beardmonster8051 Yes, I had read about that in a book by David Bergaminni (not sure of spelling - as I no longer have the book). After Hiroshima was bombed, there was a cadre in the military in the government that still forbid a surrender. Hirohito may have been the titular ruler of Japan, but there were plans to eliminate him had he called the war off after that first bomb. Some were actually on the grounds of the Imperial Palace, wanting to rush in and dispatch the Emperor. As we know, they didn't follow through. But, after Nagasaki 'happened', he recorded his speech acknowledging defeat and had it played over the radio (the first time ordinary Japanese had ever heard his voice). Once broadcast, the leader(s) of that group of military men still holding out, committed suicide.

[@NxsRuin]

The Japanese only surrendered because the Red Army was annihilating the Japanese colonial army in Manchuria in days(!) and was poised to practically walk within a few months across Sakhalin etc. with the same 1.000.000+ men warmachine that destroyed the Nazis and invade the poorly defended Japanese homeland. The United States needed a year to build up the invasion force from Okinawa. Strategic bombing had already destroyed most Japanese cities. Nukes weren't that different than a hundred planes firebombing. This is why the Japanese didn't surrender after Hiroshima or Nagasaki but waited three whole days: They were looking at the disaster unfolding in Manchuria. They didn't want a Red Army invasion, so they used the nukes as an excuse to surrender to the United States... But Manchuria mustn't be mentioned in western history. It doesn't fit the authorized narrative so it gets memory-holed.

[@Ed-ty1kr]

Ignore all that was said here, and try keep in mind that nuclear energy is clean, renewable, and too cheap to meter. And that radioactive hot particles used to boil water, or heat the air such as in this case, has absolutely no link to global warming whatsoever. It is instead due to CO2, an inert gas that plants need to generate oxygen through photosynthesis, by use of chlorophyl, a chemical that gives plants their green color.

[@jacksimpson-rogers1069]

Windscale's only resemblance to Chernobyl was bad design *and* stupidity. It is wrong to class nuclear weapons with civilian nuclear.

[@OpenCarryUSMC]

Loss of cooling at Hanford WOULD NOT have resulted in “a nuclear explosion”. It would have caused a core melt down if all other safety measures failed (assuming they installed safety measures). Even without any safety measures, loss of cooling can not result in an explosion which requires a supercritical mass which is never present (and can’t be) in a reactor or it would be a nuclear explosion (though relatively weak). Reactors run in critical, not super critical, conditions. It’s actually very difficult to create supercriticality even on purpose.
