Chernobyl Nuclear Power Plant suffers steam explosions and partial meltdown in 1986 disaster

At 1:23 a.m. on April 26, 1986, two steam explosions at Reactor 4 in Ukraine released radioactive material, forcing hundreds of thousands to evacuate and causing immediate and long-term deaths.
The disaster resulted from operator errors during a safety test, compounded by a critical RBMK reactor design flaw and poor training, leading to a massive fire and widespread radioactive contamination.
The Chernobyl exclusion zone remains one of the most radioactive places on Earth, serving as a nature preserve and a site for studying radiation effects, while RBMK reactors have since undergone safety retrofits.

The 2025 Drone Strike on Chernobyl’s New Safe Confinement: A €500 Million Breach Threatening Nuclear Safety
Overview
On February 14, 2025, a Russian drone struck the New Safe Confinement at Chernobyl, causing severe structural damage and disabling critical systems like ventilation and climate control. This breach compromised the facility's ability to contain radioactive material, increasing the risk of corrosion and potential collapse of the original sarcophagus. Despite initial radiation stability, the International Atomic Energy Agency confirmed the loss of key safety functions and warned of worsening damage without urgent repairs. Repair efforts face major challenges from high radiation, ongoing war risks, and funding shortfalls. The attack exposed the vulnerability of nuclear sites in conflict zones, highlighting the urgent need for international cooperation to secure Chernobyl's fragile legacy.
