Case studies — accidents that reshaped nuclear engineering

Technical reconstructions of the major nuclear accidents. Sources INSAG, UNSCEAR, IAEA, WHO. No drama, no extrapolation — only what the public reports document.

Each case study unpacks the accident in three layers: the design choices that made it possible, the second-by-second sequence of the failure, and the verifiable health and environmental impact. Where the consensus splits, the splits are stated.
