For a TV series the TV show Chernobyl was pretty accurate. For those who watched the the TV show, I recommend to also see an interview with an actual Ukrainian medical responder and radiation expert who was working in Chernobyl.
Probably the best non-technical book on the Chernobyl disaster is the book "Chernobyl: The History of a Nuclear Catastrophe" by Serhii Plokhy. It describes not only the accident, but also the whole soviet system and political, economical decisions which led to the resulting catastrophe.
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 that anything was wrong with the reactor, no power spike before AZ-5 was pressed.
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.
How does it make sense that the show ignores INSAG-7 when the whole plot point about the design of the control rods increasing the reactivity isn't from INSAG-1 but from INSAG-7? The same with the plotline about this defect being known, but kept from the operators. And Legasov lying about all this at the IAEA meeting? All-in-all INSAG-1 paints a picture of operator failure, INSAG-7 paints a picture of systemic failure and the show paints a picture of systemic failure.
And to nitpick: INSAG-7 doesn't disagree with INSAG-1 about the power rising just before AZ-5. From page 8 of INSAG-7: "When the turbine was tripped, the four pumps it was powering began to slow
down as the turbine speed was reduced and the associated generator voltage fell. This
reduced rate of core flow caused the void content of the core to rise and caused an
initial positive feedback of reactivity which was at least in part the cause of the acci-
dent." (page 8) This happens ~30 seconds before AZ-5 is pushed.
The same event described in Table I on page 21-22 of INSAG-1, with the part deprecated by INSAG-7 marked with {}:
01:23:04 {The personnel blocked the two-TG trip signal.} Emergency stop valve to the turbine was closed. The reactor continues operating at a power of 200 MW(th).
01:23:10 One group of automatic control rods start driving out
01:23:21 Two groups of automatic control rods begin reinsertion.
01:23:31 Net reactivity increasing with subsequent slow increase in reactor power.
The textual description on page 25 of INSAG-1 isn't much different: "When the emergency stop valve to the turbine was closed, the steam pressure began to rise. The flow through the core started to drop because four of the main cooling pumps were running down with the generator. Increasing pressure, reduced feedwater flow and reduced flow through the reactor are competing factors which determine the volumetric steam quality and hence the power of the reactor. It should be emphasized that the reactor was then in such a state that small changes in power would have led to much larger changes in steam void, with consequent power increases. The combination of these factors ultimately led to a power increase begninning at about 01:23:30."
> neither the reactor power nor the other parameters (pressure and water level in the steam separator drums, coolant and feedwater flow rates, etc.) required any intervention by the personnel or by the engineered safety features from the beginning of the tests until the EPS-5 button was pressed. The Commission did not detect any events or dynamic processes, such as hidden reactor runaway, which could have been the event which initiated the accident. “
Sure, I'm just saying the power increase did happen, according to both INSAG-1 and INSAG-7. Neither INSAG-1, INSAG-7 nor Legasovs report claims there is a rapid increase in power before AZ-5 is pushed. The claim in INSAG-1 is that this power increase was the start of a positive-feedback loop that caused the explosion. The claim in INSAG-7 was that the power increase was not a safety problem, except to the extent it caused the operator to push AZ-5.
I can't find any description of the test across the three reports mentioning that that emergency stop button is supposed to be pressed as part of the test. AFAICT the test wasn't even completed when the button was pressed as the purpose of the test was to demonstrate that the emergency core cooling system could run for at least 40 s (INSAG-1 page 17) after closing the turbine emergency stop valve. That valve was closed at 01:23:04 and AZ-5 was pressed at 01:23:40.
I have seen real world adults behave that way. Including multiple managers. The real world Dyatlov being verbally abusive is something the show has taken from the real world.
And before someone goes on about cultural difference, there are several high profile examples of American leaders/directors/business men acting in openly abusive ways.
"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.
This. Also, Higginbotham's "Midnight in Chernobyl" is brilliant prose about the disaster, from the run-up through to the aftermath. At times, it reads more like a thriller (and a fast-paced one at that!) than prose.
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, so this book invented a lot of "facts" to put the blame on the operators, Dyatlov and Fomin.
I thought the show was horrible. It was moralistic, quite on the nose, and the dialogue was pretty corny. There were a lot of obvious appeals to your average NYT and Atlantic type viewer, which is surely the main factor behind its critical acclaim.
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 would never go to talk to miners, he would just phone a subordinate and tell them to organize people, they don't need armed soldiers present to enforce something, it is not the Wild West. The authors have no clue about the soviet mentality and how soviet society operated.
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. Whoever goes gets apartments ahead of the waiting list".

The most comprehensive technical report is INSAG-7 The Chernobyl Accident - IAEA. https://www-pub.iaea.org/MTCD/publications/PDF/Pub913e_web.p...

It was a drama TV show, not a documentary. Whey compare it with TV shows, like Simpsons or movies like The China Syndrome, it was accurate.
"according to INSAG-1, the main cause of the accident was the operators' actions, but according to INSAG-7, the main cause was the reactor's design."

The AZ-5 button was pushed as normal shutdown procedure as the test had been completed, not as a reaction to some event.

It is silly how the show depicted Dyatlov as an arrogant sargeant behaving like a bully in American series about mid school kids.
This alone sets the tone of a TV show that needs to have clear goodies and baddies, and obviously life is never that simple.
There is a real interview with Dyatlov https://www.youtube.com/watch?v=N8__v9EswN4
I am not sure what your comment is getting at. Bullying is only American?

What an out of touch statement.
Have you ever worked in a restaurant or on a construction site?
Nothing the ruling class or their useful idiot cronies does publicly even approaches what's not considered abuse in those contexts.
Most modern television tends towards caricatures and melodrama.

Same goes for his other book Challenger.
I also recommend Voices from Chernobyl by Svetlana Alexievich, some of people the characters from the book are even present in the TV series.
I'm just about old enough to remember seeing the live coverage of this and Challenger on BBC Newsround, as a kid.
Couldn't find that broadcast, but HN might enjoy BBC "On this day": http://news.bbc.co.uk/onthisday/hi/witness/april/28/newsid_4...
Yes it is very good cinematic. Unfortunately it is far from the truth.
I thought the show was horrible. It was moralistic, quite on the nose, and the dialogue was pretty corny. There were a lot of obvious appeals to your average NYT and Atlantic type viewer, which is surely the main factor behind its critical acclaim.
I found the dialog fairly realistic. Maybe because I grew up in a similar country - it sounded like real world people talk.
Also, events and actions were close to how reality unfolded with simplified cast of characters, basically.
Simplified characters and strongly amplified and invented extra drama and events.
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.

Well, how else would you show a minister giving a command to n layers of people before going to the miners on a drama show?
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. Whoever goes gets apartments ahead of the waiting list".
