Your comment reminded me, an excellent showcase of institutional shenanigans is the Chernobyl miniseries on Netflix. Denial, blame, coverups, accountability. It's a very well made series in a grim Soviet setting.
Just please don't take it as a documentary. It's a disservice to the people that actually worked at the plant that day and portrays them as arrogant fools, which none of them actually were. That Chernobyl Guy on YouTube did great breakdowns.
* The soviets designed a nuclear reactor and engineering plan/blueprint to making power plants
* That engineering plan required certain safety tests to be preformed before actually operating the plant
* Chernyobl did not pass those safety tests before plant operation
* Chernyobl then tried to run those safety tests after the plant was in operation (for some time).
* Chernyobl then catastrophically failed the safety tests due at least to the test setup being incorrect (you aren't supposed to be operating the plant before hand).
