Pripyat, the purpose-built atomgrad next to the plant, was evacuated on 27 April. The Soviet state confirmed an accident only after Swedish monitors detected the plume on 28 April. IAEA’s INSAG-1 (1986) first stressed operator error; INSAG-7 (1992) shifted the main cause to design and a weak safety culture. The 1987 Chernobyl trial convicted plant managers.

Chernobyl disaster · tagline
On 26 April 1986 an explosion at reactor 4 of the Chernobyl plant in the Ukrainian SSR became the worst nuclear accident on the public record and rewrote international nuclear law. At 01:23 on 26 April 1986, unit 4 of the Chernobyl Nuclear Power Plant exploded during a planned turbine-rundown test.

Chernobyl disaster · The engineering case is closed: a test plus RBMK design features
The engineering case is closed: a test plus RBMK design features produced a prompt power excursion. What remains contested is how to count later cancers and how to value the exclusion zone. English-language memory now runs through the 2005 Chernobyl Forum, UNSCEAR annexes and, after 2019, a television miniseries that is not a primary source.
Chernobyl disaster · paras 1
Operators intended to see whether a spinning turbine could power emergency pumps during a station blackout until diesel generators started. The test had been postponed and was run on a night shift with the reactor in an unstable low-power state. Control-rod and coolant conditions violated the plant’s own operating limits.
