How did the Chernobyl disaster end?

The Chernobyl disaster ended with the containment of the reactor and the establishment of a sarcophagus over the destroyed reactor to prevent further release of radioactive materials. Emergency responders initially worked to extinguish the fires and stabilize the situation, while a massive effort was made to evacuate nearby residents. Over time, the area was further contained with the construction of the New Safe Confinement structure, completed in 2016, which encapsulates the original sarcophagus. The long-term effects of the disaster and the management of the exclusion zone continue to be addressed today.
