Episode notes
Systemic Causes Over Single Mistakes
- Chernobyl's disaster stemmed from systemic Soviet culture: secrecy, impossible targets, and corner-cutting rather than a single operator error.
- David Olusoga argues that these political and organizational failures made the reactor vulnerable long before April 1986.
Sheep Restrictions In England
- David Olusoga recounts working in 1989 testing sheep in northern England after Chernobyl fallout contaminated pastures.
- He saw long-lasting restrictions: Britain didn't fully lift sheep movement bans until 2012.
Size Saved Face, Sacrificed Safety
- Soviet reactors (RBMK) were built huge to showcase power and save costs, which increased safety risks like lack of containment buildings.
- Bigger reactors raised exponential containment costs, so designers omitted them, leaving no last line of defense.
