The explosion blew off the 1000-ton sealing cap. The ‘Chernobyl Nuclear Power Plant’ was officially named the ‘Vladimir Ilyich Lenin Nuclear Power Plant’.

Il a été refroidi par un étang artificiel, qui est alimenté par la rivière Pripyat à environ 5 kilomètres (3 mi) au nord-ouest de sa jonction avec le Dniepr . Workers constructed a concrete and steel sarcophagus around Unit 4. This structure had weakened, so a permanent structure was built around it. It cost at least $765 million. At first, animals did experience mutations from the radiation. It wasn’t until 5 a.m. the following day that Reactor No. The initial fire was stifled by about 5 a.m., but the resulting graphite-fueled fire took 10 days and 250 firefighters to extinguish it, according to NEA. While there may still be additional cases of cancer that emergency workers, evacuees, and residents may experience throughout their lifetimes, the known overall rate of cancer deaths and other health effects directly related to Chernobyl's radiation leak is lower than was initially feared. Exactly 33 years after the Chernobyl nuclear power plant exploded, the name "Chernobyl" is still synonymous with disaster. En 2013, la pompe transportant l'eau de la rivière dans le réservoir de refroidissement adjacent à l'installation a été mise hors tension, le puits thermique devant s'évaporer lentement. Cela a ensuite conduit à une fuite d'hydrogène, utilisé comme liquide de refroidissement dans le générateur synchrone dans la salle des turbines, "ce qui a apparemment créé les conditions pour qu'un incendie se déclare dans le toit et que l'une des fermes soutenant le toit s'effondre".
