History

Historical Context

The 26 April 1986 explosion of Reactor 4 at Chernobyl created a 30-kilometre exclusion zone and forced the evacuation of more than 100,000 people, prompting sweeping Soviet safety reforms. Decades later, Ukraine’s Zaporizhzhia plant faces a projected 2025 breach of Reactor 4, with director Denys Khomenko warning of possible collapse and costly repairs that could echo Chernobyl’s legacy.
