A view from the former eastern block. We - the Czech Republic - enjoyed the joys of soviet occupation for 31 years. To this day soviets/russians didn't officially acknowledged emplacing nuclear munitions on our soil. But interestingly enough, there are many "soviet style" nuclear munition bunkers across our country. And many rocket emplacements which were manned exclusively by soviet rocket troops and were hurilly disarmed after the Velvet revolution. I still remeber the state of the western Bohemia in the 90s. It was still frozen in the 40s. Why? The region was expected to be destroyed by nuclear strikes from both sides, so why rebuild it? Some buildings in Pilsen still had marks from shrapnel and bullets from WW II by early 2000s.

This was mostly a manufacturing and assembly decision - they had to design things before they had certainty on some of their calculations, so they needed to be able to adjust the amount of uranium in the system. So the cylinder target was actually designed to be made of uranium disks held together by a bolt running through them. And they could just adjust the number of disks used when the time came. Harder to do that with a cylindrical shell, and bad to use a bolted-together projectile. So the single-cast cylindrical shell was made the projectile, with an inner, cylindrical stack of disks as a target.

4:08 - "With only 6.4 kg of plutonium, ... compression uranium-235 to twice its normal density." Well, which was it - plutonium or uranium-235? The answer is it was plutonium, and there was a uranium tamper in Fat Man in addition to the core, but it was uranium-238, not -235. The core was compressed to 2.5 times its diameter, which is 17 times its volume, therefore 17 times its density. This is NOT radiation implosion - that refers to the manner in which the fusion secondary of a thermonuke (like the Tsar) is imploded. The implosion in the Fat Man was straight-forward explosive compression. 6:12 - "Since details are not available, I'll have to extrapolate..." The details have been available since published in a popular magazine in 1977, which the AEC made a huge stink over. The magazine claimed all the details were published piecemeal in other unclassified documents; they won their case. That was 40-50 years ago. The details are available. The internals of the Tsar are available; hell, in Wikipedia, in an article charmingly named "Tsar Bomba". There were two primaries and two secondaries on each end of the massive tertiary stage; special work was done on the electronics to synchronize all of the pieces. 6:35 "...but lithium also breaks down, increasing yield." You betcha. If the lithium did not breakdown into tritium, there would have been no secondary yield. The reaction is very specifically "deuterium-tritium fusion", other combinations of hydrogen require even higher temperatures. 6:41 - The Castle Bravo contained large quantities of Li-6 and Li-7 which were responsible for a 2.5 times increase in blast yield, from 6 to 15 megatons." Very confusing - 2.5 times what? Actually, the Li-7 was thought to be unreactive, so the 6 megaton yield was based on the 40% Li-6 in the "Sausage" test bomb. The Li-7 turned out to be (surprise!) just as reactive as the Li-6, thereby increasing the yield by 1.5 times over the estimate. 8:51 "At first the Tsar Bomba was supposed to have a third stage capable of adding an extra 50 megatons.", Well, this is often confused when speaking of nukes. The Tsar had three stages - the primary is the fission bombs, the secondary was two fusion stages on either side of the tertiary stage - another fusion stage of a massive scale. That combination raised 50 megatons. Surrounding all three stages individually was that uranium-238 tamper, a fixture of (nearly) all nukes, starting with Trinity. That is not referred to as a "stage" in bomb engineering literature; it is simply the tamper. Surrounding fusion stages, the tamper releases huge amounts of fission (obviously of much higher yield than the primary fission bombs) from the high-energy neutrons. As you say, THAT was what was absented from the Tsar (or rather replaced by a "base metal" tamper) to keep its yield to 50 megatons. So it had three stages, and the tamper was replaced to keep the yield rational from a safety and PR standpoint. Insult to injury - your title is click-baity, which I'm sure you realize. Your point is that the Tsar could have been 100 MT and was, therefore, mightier than the actual Tsar, but you don't state that in the video, so the point of your title is lost. The Tsar, as is, is the world's record-holder in terms of actual, realized yield.

"The core was compressed to 2.5 times its diameter" It was compressed such that its diameter was 2.5 times larger than originally? That's not a compression, that's an expansion. Its diameter was not decreased by a factor of 2.5, it's volume was. Also 2.5^3 is 15.625, not 17. The density increase according to open literature was by a factor of 2 - 2.5. First principle efficiency equations indicate a compression factor of 2 was required for the yield it produced. Plutonium cannot be compressed by a factor of 17 by a single shock. Nor is a compression factor of 17 necessary to produce the yield it did. The Tsar bomba did not use two primaries. Without lithium transmutation, there would still have been secondary yield from sparkplug fission, D-D fusion and some tamper fast fission. D-D reactions dominate early on in the fusion burn. Its the neutrons from this reaction that breeds the tritium. 2.5 times 6.

The hard part is always manufacturing the fuel. Uranium enrichment is still the bottleneck that stops most countries from making their own bombs. The plutonium has to be made in a uranium fission reactor then separated chemically. So it's not any easier since the reactor designs good at making plutonium need enriched uranium too.

@chouseification

3 жыл бұрын

graphite moderated _natural_ uranium was used in many of the early plutonium production reactors - look up Windscale. Even the RBMK design from the Soviet Union (Chernobyl was that style) whose spent fuel was processed for plutonium used only slightly enriched fuel. One key thing to remember about a plutonium production reactor is that the fuel canisters or rods are changed frequently, either like Windscale and Hanford which pushed new canisters in the front which displaced old canisters out the back; or the RBMK design where they had a refueling machine that could open up one fuel channel at a time and swap out the rod while the reactor was running. If you leave the rods in too long, you'll burn up the Pu you want, so frequent fuel changes are a normal part of the design. Going directly to plutonium is actually an option, at least for fission and boosted fission bombs - if you want to go thermonuclear you will need _depleted_ uranium (plus lots of lithium deuteride, tritium, etc) but there's no place where you absolutely _need_ enriched uranium in a bomb. Power plant yes, bomb very much optional.

Couple top o the line centrifuges and you’re good to go.

“Making a bomb is simple” is where your incompetence shows. It not only hard to produce enriched uranium, is also quite hard to create a clean explosion by compressing the fissile material quickly enough. If you don’t do this properly, they yield will be small, parts of fissile material will just melt and fly in all directions. There’s plenty of math and engineering tricks involved. And Plutonium is different from U235, harder to work with. Fusion bombs are hard too.

I love this channel so much🙏 Always interesting topic and results based on science... Keep them coming 😉

ERROR in this video - Fat Man is first described correctly as a plutonium bomb at 4:05. Then at 4:12 the core of the Fat Man bomb is described as U-235. WRONG. The core was Pu-239. Also, the video misses the REAL reason a plutonium bomb has to have such a complex implosion triggering mechanism. Pu-239, unlike U-235, fissions and goes into a chain reaction much much faster and easier. The gun device is far too slow in compacting enough Pu-239 together into a critical mass fast enough to create a powerful nuclear explosion. Instead, enough of a runaway chain reaction would have started at the leading edges of the impact point between the two sub-critical masses to blow the two fissile masses apart before most of the Pu-239 had entered into a good size bomb quality runaway chain reaction. The result would be a "fizzle" a very very low yield explosion. Some of North Korea's atomic bomb tests have been like this - so low yield they were probably fizzles. Pu-239 is a natural byproduct of most nuclear reactors using uranium and can be separated out relatively easily using chemical means. However, Pu-240 will also be in the mix, and it has a lower ability to undergo fission after getting hit by a neutron (it tends to capture the neutron instead and turn into Pu-241), which ruins the explosive fission chain reaction qualities of Pu-239. And so plutonium derived from ordinary uranium reactors has to also undergo isotope enrichment to bomb grade Pu-239. The other option is to build a special breeder reactor using U-238 to specifically produce highly concentrated Pu-239. U-235 occurs naturally in mineral ores, while Pu-239 with its shorter half life does not. And, so in any start up program to build an atomic bomb, it's a lot easier and you save a lot of steps by going for a U-235 enrichment program to make your first bomb. Uranium enrichment thus becomes the first step towards building an atomic bomb.

The issue of Pu-240 is less to do with its poorer neutron properties and more related to its high spontaneous fission rate increase the predetonation probability. There's no record of Plutonium ever being enriched. Any conventional civil PWR can be operated such that it produces weapons grade material.

@@Evan_Bell Yes, Pu-240 will also under spontaneous fission more easily than Pu-239 (this is a separate problem from its tendency to capture neutrons whizzing around from the ongoing fission reactions), and this also increases the likelihood of a high Pu-240 content plutonium bomb detonating with a fizzle. Running a nuclear reactor with the uranium fuel undergoing fission and neutron bombardment for only short periods of time before the fuel is taken out to be chemically processed to isolate the plutonium results in the highest concentrations of Pu-239 and lowest concentrations of Pu-240, and this is how weapons grade Pu-239 is most easily produced. Current commercial nuclear reactors for this very reason are not designed to easily operate in this fast breeder mode, with a constant cycling in and out of the uranium fuel. This could be done, but is much more of a slog than using a fast breeder reactor specifically designed to do this. The spent uranium fuel from commercial reactors thus contain plutonium with relatively high percentages of Pu-240 relative to Pu-239 from the long periods of time that the fuel has been in the reactor under neutron bombardment. Isotopic separation of Pu-239 and Pu-240 is possible, but impractical because it's just so much easier to run a uranium reactor in a fast breeder mode to get the weapons grade high concentration Pu-239 and low concentration Pu-240.

@@gandalfgreyhame3425 Spontaneous fission is the prime reason for minimising Pu-240 content. Weapons have been tested with as high as 19% 240.

Low burn-up campaigns are not reactors operating in "fast breeder mode". Commercial LWRs can't operate in the fast spectrum.

I think you have conflated tamper and reflector. The neutron reflector is a material that reflects neutrons back into the reaction so they have a second chance to trigger a fission event. The tamper was jus a really heavy she'll surrounding the reaction so it's inertial mass would hold the reaction from expanding for a few extra microseconds because a few extra microseconds can dramatically increase the yield of the reaction. They were usually in the same layer but not the same materials. I believe beryllium is usually used as the reflector and whatever the heaviest material they have available when designing the device is used for the tamper.

All of your comments are 100% correct. The tamper is so important that the Manhattan Project physicists considered using gold as the tamper because it was cheaper than uranium in 1945. As the compressed core fissions and starts expanding, once it reaches 1.12 times its diameter the fission stops because it is no longer dense enough for fission to continue. That's how important the tamper is as the additional inertia created by the tamper keeps the core critical for milliseconds longer which greatly increases the yield.

Thanks for the video. Few interesting facts you didn't mentioned though. -Sources don't agree on the yield, US sources says it was 58 MT, Soviet source says the bomb had 50 MT -Tsar bomba original yield was about 100 MT but was reduced for the live test by about a half -Theoretical limit for TB design was about 150 MT -Sakharov in his memoirs mentions that the main design in theory could be modified to increase the yield to 1 GT! Creating huge single bombs is not practical because a lot of power is simply wasted by escaping into space. A single missile with power of 30 or 40 MT but divided into many smaller warheads will be able to basically destroy the whole country size of France. For example new Russian missile R-28 Sarmat can have yield up to 50 MT but in 20 or more warheads or MIRVs. This will mean 20 bombs 2.5 MT each. So in case of France, 20 big cities can be destroyed with just one missile. A whole country would collapse in the matter of minutes. A single 50 MT bomb would not be able to do that.

I thought the reason the tsar bomb was "only" 50 MT when tested compared with a design yield of 100 MT was because they used an non fissionable lead tamper to reduce fallout.

Another example would be the Chicxulub Impactor, the energy released in the impact is the equivalent to 10,000 times the modern nuclear arsenal, but if you somehow launch/throw a nuclear bomb and had the same energy released the effects would be different (and I'm not talking about the contamination).
