What happened at Chernobyl?

Chernobyl was a real tragedy — but also a uniquely Soviet one that says little about modern nuclear power. The 1986 disaster required two things Western reactors don't have: the unstable RBMK design, and the absence of any real containment structure. No Western-style plant could fail the same way.

The immediate causes are settled; the long-term death toll is contested, with mainstream bodies (WHO, UNSCEAR) estimating far lower numbers than some activist sources. The encouraging reality is that even history's worst nuclear accident, in the worst possible design, caused far less harm than widely feared — while the surrounding exclusion zone has become a thriving wildlife refuge.
