What was its actual effect on the Soviet Union politically, both internally and externally?
How did it escalate into such a massive fucking disaster?
Was it inevitable?
What's some good reading/watching on the event?

it was a truly example of soviet efficiency.
There were a lot of things that had to happen in a certain way for the disaster to occur and unfortunately they did happen. All of the things that occurred compounded to make the reactor extremely unstable and every safety feature designed to be fail-safe was turned off. The reactor was operating completely outside of its design. Due to poor training and lack of knowledge as well as deviation from test protocols the operators made it possible for the reactor to be in such a state. That said, the reactor design also had many flaws because it didn't comply with standards of nuclear reactor safety.
The disaster was probably inevitable, in my opinion. Given the lack of safety and non-compliance of safety standards, lack of training, not following procedure, bad procedures and instructions, lax safety culture, faulty design, and lack of foresight if it didn't happen that day it would have happened on another. The same test was done 4 years previous and it was fine, for instance.
During the time it made US-Soviet relations better/ more cooperative. Because of it people are still incredibly (and unreasonably) scared of nuclear power.
