Events

  • NASA's space probe "Voyager 2" makes the first encounter with Uranus.
  • January 28NASA's space shuttle "Challenger" explodes on launch during a live broadcast, killing all seven astronauts aboard. Their bodies are located on March 9.


  • April 26Chernobyl disaster: A high-power channel-type reactor at Chernobyl Nuclear Power Plant in the Ukrainian Soviet Socialist Republic reaches prompt criticality.
    The initial emergency response, together with later decontamination of the environment, involved more than 500,000 personnel and cost an estimated 18 billion Rubles.
    The accident occurred during a safety test: During a planned decrease of reactor power in preparation for the test, the operators accidentally dropped power output to near-zero.
    While recovering from the power drop and stabilizing the reactor, the operators removed a number of control rods which exceeded limits set by the operating procedures.
    Upon test completion, the operators triggered a reactor shutdown. Due to a design flaw, this action resulted in localized increases in reactivity within the reactor.
    This resulted in rupture of fuel channels, leading to a rapid decrease in pressure which caused the coolant to flash to steam, leading to the creation of a positive feedback loop.
    This process resulted in steam explosions and melting of the reactor core. The meltdown and explosions ruptured the reactor core and destroyed the reactor building.
    This was immediately followed by an open-air reactor core fire. In response to the initial accident, a 10-kilometre (6.2 mi) radius exclusion zone was created 36 hours after the accident,
    from which approximately ~49,000 people were evacuated. The exclusion zone was later increased to 30 kilometres (19 mi) and an additional ~68,000 people were evacuated.
