April 26, 1986, the world's worst nuclear power plant accident
occurs at the
Thirty-two people died and dozens more suffered raOndiation burns in the
opening days of the crisis, but only after Swedish authorities
reported the fallout did Soviet authorities reluctantly admit that an
accident had occurred.

April 25, 1986, a group of engineers began an electrical-engineering
experiment on the Number 4 reactor. The engineers, who had little
knowledge of reactor physics, wanted to see if the reactor's turbine
could run emergency water pumps on inertial power.
As part of their poorly designed experiment, the engineers
disconnected the reactor's emergency safety systems and its
power-regulating system. A chemical reaction, driven by the ignition of gases
resulted in an explosion and ensuing fire,
more than 50 tons of radioactive material were released into the
atmosphere, where it was carried by air currents.
On April 27, Soviet authorities began an evacuation of the 30,000
inhabitants of Pripyat. A cover-up was attempted, but on April 28
