What goes on inside a nuclear reactor? It’s kind of like one big dodgeball game 👇 The main job of a reactor is to house and control nuclear fission – a physical process where atoms split and release energy. Neutrons are introduced to the uranium particles inside the fuel pellets. When the uranium is hit by a neutron, it splits apart, releasing energy and more neutrons. The neutrons hit other uranium particles and eventually start a chain reaction. You can learn more about how a nuclear reactor

The first authentic video to be taken of the reactor at 4pm, 14 hours after the explosion. The video was taken from the first helicopter to fly over the disaster zone to evaluate radiation levels. The view is foggy due to radiation, which also explains why the shot was not taken too close to the window. Later, radiation experts learnt that at 200 meters above the reactor, levels reached 1500 rems, while their counters could not exceed 500 rems. Video footage: Igor Kostin READ MORE 👉 How to visi
