Anatoly Dyatlov
Deputy chief engineer, night of the test
Supervised the 26 April test. Convicted in 1987. Later wrote that the rod-design defect, not only night-shift errors, explained the spike. INSAG-7 partly vindicated that technical point without erasing rule-breaking.
Viktor Bryukhanov
Plant director
Convicted in 1987 for safety failures and for the quality of the first reports upward. English accounts often treat him as the face of late Soviet industrial management.
Nikolai Fomin
Chief engineer
Tried with Bryukhanov and Dyatlov. The 1987 court treated the plant’s safety paperwork and test authorisation as criminal negligence under Soviet law.
Valery Legasov
Chief scientific speaker in Vienna
Led the Soviet technical briefing to IAEA in August 1986. His later notes on safety culture were widely quoted after his death in 1988. Drama has since outrun the archive.
Mikhail Gorbachev
General Secretary, CPSU
The accident became a test of glasnost. His government moved from a short TASS note to international notification conventions the same year. Memoirs treat Chernobyl as a political accelerant.
Hans Blix
IAEA Director General
Flew over the site in 1986 and chaired the international response. English diplomatic memory uses Blix as the face of the IAEA’s first Level 7 crisis.
