Film of largest nuclear bomb declassified
Plenty of aviation, film and radio nostalgia in this very detailed film.
Was it their choice to detonate on a cloudy day? Shared from Sky News: Largest-ever hydrogen bomb blast shown in declassified Russian video https://news.sky.com/story/largest-e...video-12056911 mjb |
I liked the introduction where they spoke of critical timing in the millionth of a second and then cut to guy holding a stop watch in his hand

I like the soothing music. :)

Probably the ultimate example of the daft spate of willy waving that had been going on between the US and the Soviet Union for the decade or so earlier, each trying to out do the other with the size of their thermonuclear capability. Pretty pointless, really, when a 50MT bomb was not exactly a practical weapon to deploy, had the world descended into nuclear armageddon. Probably 90% of the reason for producing this bomb was propaganda, I suspect.

I don’t understand why they describe it as a ‘clean bomb’. WTF is ‘clean’ about it? It was polished before the exploded it?

There's still some fallout, because the fusion reaction requires a fission reaction to trigger it, but nothing like the sort of contamination created by a relatively large fission device, such as the ones detonated over Japan, as the fission trigger within a fusion device is only used as a source of X rays to trigger the fusion reaction in the main fuel. There were probably three stages in the Tsar Bomba, a conventional explosive initiator, which compressed the fission trigger, much the same as a small conventional fission bomb, and the focussed X rays from that fission reaction initiated the fusion reaction that produced almost all the power of the device. The nature of a fusion reaction consumes pretty much all the fuel, leaving little in the way of material that could contaminate the area. |

Thanks for the answers 👍

It was a very low fallout design, as they didn't include a U238 tamper. Pretty much all the fissile material in the trigger was consumed, and the vast majority of the output was thermonuclear, so didn't produce any significant nuclides, at least at ground level. One of the advantages of thermonuclear (fusion) devices over earlier fission devices was the very much reduced fallout, as well as the massively greater yield.

The nature of a fusion reaction consumes pretty much all the fuel, leaving little in the way of material that could contaminate the area. To limit the amount of fallout, the third stage and possibly the second stage had a lead tamper instead of a uranium-238 fusion tamper (which greatly amplifies the fusion reaction by fissioning uranium atoms with fast neutrons from the fusion reaction). This eliminated fast fission by the fusion-stage neutrons so that approximately 97% of the total yield resulted from thermonuclear fusion alone (as such, it was one of the "cleanest" nuclear bombs ever created, generating a very low amount of fallout relative to its yield). There was a strong incentive for this modification since most of the fallout from a test of the bomb would likely have descended on populated Soviet territory. |
Despite the considerable expertise in nuclear physics, the digital age had not arrived, they needed analog cameras to make a record of an analog sensor.

Clean bombs are the difference between roasting alive in milli-seconds and having your hair fall out over days before you die

George C. Scott at his best.

It's funny how George C really didn't want to diminish his professional image by playing this part. When he did, he obviously threw himself into the part.

Actually early Soviet corona virus vaccine trials.

Black Sun by Owen Matthews is a very good spy/thriller that I read months ago using the building of this bomb as a theme.

The mother of all nukes, The Russian ‘Tsar Bomba’
Newly released footage.
This is newly declassified footage of the biggest nuclear bomb blast of all time. The Russian ‘Tsar Bomba’ weapon was dropped on 30 October 1961. It exploded with the force of an estimated 50 million tons of tnt. Rosatom State Atomic Energy Corporation, the Russian State Corporation Headquartered in Moscow released the video to commemorate the 75th anniversary of Russia's nuclear industry. |
Cosmic Irony the guy who designed that particular weapon , Sakharov was awarded a Nobel peace prize :)
The model of aircraft that carried the payload is still in service and a similar aircraft was playing War games off Alaska this week. Not the scarey version the one with the hypersonic cruise missiles and Mig 31 escorts , just the observation model. The Nazis were working on a clean Nuclear device , start worrying if the designs and plans for the clean weapon they tested in Poland are ever found . Although such a device would make mining more profitable |
" start worrying if the designs and plans for the clean weapon they tested in Poland"
Who tested a N device in Poland? |
Who ? Google it . Those guys in the Hugo Boss uniforms did make several different types of big bangs . Several failures , a big dirty one and several clean big bangs in Poland . Old news really was in the papers last year and on the History Channel as well . A bigger bang than the Recent Thermobaric devices which would suggest a clean burning fuel or a failure to ignite the dirty nuclear fuel .
