Are the RBMK designs good at producing plutonium? For some reason I feel like I've heard that before, but perhaps I didn't understand that properly or am confusing it with a different type reactor.
There were a couple of images that stood out to me. Early on there was a scene with two attractive women in bikinis. Sadly, I did not see them again. The second was when they talked about the reactor explosion they showed a nuclear explosion. I have to take issue with that - it was an explosion that spread nuclear material, not a nuclear explosion from fission, as was implied by the image. Big difference between steam and then hydrogen going off as opposed to an actual nuclear explosion. That's about the only things I took issue with in the show.
Just about any reactor that has U-238 in it will produce Plutonium. Not sure if the RBMK's are better Plutonium producers than western light water reactors. There's a little known fact that every fuel assemly in a light water reactor starts producing Plutonium almost as soon as it starts up. By the time a light water reactor fuel assembly is ready to be discharged from the reactor, almost 40% of the heat produced by fissions comes from Plutonium 239 or 241 fissions.
The whole idea of the nuclear fuel cycle as envioned in the 1950's and 1960's was that when a fuel assembly was discharged from a reactor, it would be reprocessed. The remaining unused U-235 and newly created and unused Pu-239, 241, etc would be chemically separated from the fission products in the fuel assembly and reinserted into new fuel assemblies. It was significantly economical to do this and extended the life of uranium extracted from the earth almost indefinitely. There was nothing really new in the process. The government had been doing it for years to harvest Plutonium from the production reactors for nuclear weapons. But in the late 1970's, Jimmy Carter (himself a product of Rickover's nuclear navy) banned all reprocessing and that ended the reprocessing dream.
I agree with you that there was not a bomb-like nuclear explosion. It seemed to have been a high power transient that resulted in melted fuel, fractured coolant pipes, extremely high temperatures that caused a lot fires - including graphite fires. As I understand it, the uranium was mixed in with graphite blocks. One thing I got from the documentary was that they really don't know (or aren't saying) exactly what happened. They have computer simulations suggesting what happened.
There was one statement that the explosion was the equivalent of many times the power unleashed by the Hiroshima and Nagasaki bombs. I don't think that is true. If it was true, just about everything and everybody in a five mile readius would have been destroyed/killed. I think the other three reactors at the site continued operating for several years, so clearly there weren't atomic bomb like explosions.
Right at the end, they said that 200,000 people had died from the accident. That is probably way too high. General consensus is that somewhere around 100 people died as a result of the accident within a few days. As far as those who have died from long term effects, that number is probably in the 10,000 range. As always, reliable statistics were never the strong suit of the USSR.
I'm sure most of the 5,000 guys who were shoveling graphite/fuel from the roof of the building suffered radiation related diseases. Of course, they all smoked and probably drank a lot of vodka, so who knows what was the primary cause of an early death. Same with the chopper crews and the tunnelers.
I think the young girls in bikinis were placed in the story to show that life was pretty good in Chernobyl and was almost western-like. Those girls probably became models in NYC or LA and/or became tennis pros.
And in the ultimate irony, "bikinis" are named after Bikini Atoll in the Marshall Islands (half way between Kwajalein and Enewietok Atolls which were the sites of savage fighting against the Japanese in WWII). After WWII, Bikini Atoll was the site of numerous nuclear weapons tests which left the Atoll severely radioactive and uninhabitable. There were 23 nuclear explosions, including 20 thermonuclear explosion. When the designers of the swimwear that became the bikini were looking for a trendy, modern, up to date, name that would connote all things modern, they seized upon the Bikini Atoll where cutting edge technology was taking place. Thus they named the swimwear the "bikini". So every time one of these little girls puts on a bikini, they are really commemorating thermonuclear weapons. I'm sure they'd all be aghast if they knew this.
