On April 26th 1986 a reactors power in the plant dropped suddenly and the workers tried to compensate for the low power but the reactor went out of control. The reactor eventually exploded.It took 2 weeks to put the explosion out and citizens were told to stay indoors at this time. Chernobyl, the town, was not evacuated until 6 days later.
On site 31 people died but later thousands died from long term effects from the radiation.

Right after the explosion happened, the reactor was put into a sarcophagus to prevent further leakage.
The TMI accident in 1979 had a huge impact on Western reactor design and operating procedures. The International Atomic Energy Agency safety review projects for each type of Soviet reactor. This brings together operators and Western engineers to talk solely about safety improvements that could be made.
