This information is not discussed in INSAG-7. It is from trial testimonies sourced from the book by Nikolai Karpan (deputy chief engineer of Chernobyl NPP), who was present at the trial and made notes himself.

For the rundown test, after the valve cut-off, it is irrelevant whether the reactor was shut down or not. The working plan for the test only specified that it was supposed to run before a planned maintenance period, so the shutdown was impl

Easy but boring. Realistically, the workers would be gathered in a hall and their immediate boss would give a speech: "The party and the government want you to serve the Motherland at this heroic moment and volunteer for a hard job. Wh

I worked in the soviet nuclear industry (Sredmash) in the 1980s. The dialogs and characters are completely unrealistic and made me cringe. Everyone looks overemotional and infantile. The hierarchical interactions are comical - a minister w

"Verbal abuse" isn't a concept that existed in the Soviet Union. Giving or receiving instructions with as many "suka blyat" inserted between each word as possible wasn't abnormal.

The TV show pretends to be historically accurate, and many people believe that it is true. I would suspect that the majority of people have no other sources of information about Chernobyl other than this TV show.

Higginbotham uses Medvedev's book as a source. Medvedev worked in the Ministry of Energy and he was their special representative in Chernobyl after the incident. His task was to cover the asses of the ministry and the reactor designers

No, the show is not accurate. The last episode repeats the lies that Legasov told at the IAEA meeting in 1986, that were published as INSAG-1, and the show completely ignores INSAG-7. There was no drama in the control room, no indications t

In the USSR, you usually don't have a spare guest room. An unmarried young man would be lucky to live in a separate apartment; otherwise, it is usually just a bed in a dormitory. At best, it is a one-room (12-20 m2) apartment with a ki

There is an old practice of having an alternative `toor` user with UID=0, with a different shell and password, in case someone screws the primary `root` account. https://en.wikipedia.org/wiki/Toor_(Unix)
