Its been 30 years that the Chernobyl incident happened.
In the early morning of April 26, 1986 the Chernobyl technicians were undertaking a drill when everything went wrong and the number four reactor exploded.
The Soviet Union would remain quiet until pressured after Swedish nuclear workers had problems getting into work.
Today the area is still contaminated and scientists say it will be centuries before it will be habitable again.
The question is have we learned anything about it? That is still to be answered.
Currently there is a shield and Russia has a plan to build even bigger shield over the reactor.
Hopefully the thousands killed will be remembered and help solve future issues.
