Chernobyl and international nuclear safety
Energy · Technology · Infrastructure
The accident at Chernobyl’s reactor 4 released large quantities of radioactive material and had lasting human, environmental, and social consequences. For energy, it exposed failures of design, operation, and communication and spurred international cooperation and safety standards; it does not justify treating all reactors or all risks as equivalent.
