Finished Chernobyl.
Great little miniseries. Even though you basically know what happened by the final episode,
Why, what happened?
I know you're being factious, but really in the final episode they show you just how much of an irresponsible douche the main reactor controller was on the night of the event. The show starts right after the explosion and it's unclear who was actually responsible for what. By the final episode they show that the lower-level grunt operators were taking orders from a grossly irresponsible manager....and that was compounded by the Russian's cost-effective "shut it all down" method which, when everything was going to shit because of improper procedure, caused the reactor to explode.
Basically, the Chernobyl power plant was well on its way to being an actual nuclear bomb due to gross mismanagement, and when they hit the shutdown switch to stop the reaction, it caused the reactor to explode because of the flawed soviet design and the stress the reactor was already under. Not as bad as an actual nuclear explosion, but still the worst nuclear reactor accident in human history.
If you've got any interest in nuclear catastrophes or understanding how reactors work, the show is a great watch. I feel like I learned a lot while also being entertained / horrified.
And to HBO's credit, in the epilogue of the final episode they specifically note where they combined dozens of nuclear scientists in to a single character for the sake of the story. That was my one gripe about the historical accuracy of the show and I'm glad they made it a point to note where they did things for the sake of television.
One thing that I never did understand....is why the control rods were tipped in graphite. If graphite in a Russian reactor causes an increase in reactivity, why did they tip the control rods (which slow down the reaction) in a thing that
increases the reaction? So that when the control rods are only partially lowered there's still graphite at the head to maintain reactivity? I dunno.
Honestly inserting the control rods which caused the reactor to explode due to the graphite tips actually prevented the reactor from going critical. It stil blew up but it's the reason the Exclusion Zone today still looks like a forest today instead of a blasted wasteland. So I guess it was the better outcome.
