A partial core meltdown occurs in reactor No. 1. The extent of the accident was not made public until 1985. The reactor was repaired and put back into operation within months.
-
Chernobyl was built throughout the 1970s and 1980s. The last reactor was finished in 1983
-
On April 26, 1986 in Ukraine the Chernobyl radioactive plant exploded. It was one of the largest radioactive explosions in history. This was caused from a flawed Soviet reactor Along with many bad decisions by inadequately trained personnel.
-
115,000 people evacuated within 36 hours of the event.
-
The wind changed directions and started spreading radiation even farther than it was originaly spread.
-
It was on this date that the infamous "elephants foot" was discovered. This is a smoldering hot chunk of melted reactor cores and other radioactive materials that melted through the concrete and is one of the most deadly pieces of waste on the planet.
-
$2.2 billion was spent to cleanup Chernobyl. It was a while before the cleanup crews could safely go to the site. Even with this being said, several thousand cleanup people died and became disabled from the radiation.
-
The reactor malfunction has now cost the Soviet Union $267 billion in total including cleanup and energy loss.
-
Reconstruction work on block 5 and 6 stopped, and decided not to complete the reactors.
-
A fire breaks out in the turbine hall of Reactor 2. The fire began in Turbine 4 while it was idle for repairs. A faulty switch caused a surge of current to the turbine, igniting insulating material on some electrical wiring.This subsequently led to a leak of hydrogen, used as a turbine coolant, into the turbine hall which created the conditions for fire to start in the roof and for one of the trusses supporting the roof to collapse.
-
All tours of Chernobyl and its sorroundings are offically banned.
-
Today Chernobyl is still radioactive. There are spots now that are safe to be in and there are spots that will kill you almost instantly from radiation. The wildlife in the area is not typically physically mutated but may have differences in DNA. Most animals have a shortened life span from the radiation. Some people live there but it is not safe to there for most people.

In Chernobyl they used a process called fission which is where they split a nucleus. When the nucleus is split energy is released. Cox, E. (n.d.). What Is Nuclear Fission? - Definition & Process.
