Desastres Nucleares

Chernobyl
The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine, which was under the direct jurisdiction of the centralMoscow's authorities. An explosion and fire released large quantities of radioactive contamination into the atmosphere, which spread over much of Western USSR and Europe. It is considered the worst nuclearpower plant accident in history, and is one of only two classified as a level 7 event on the International Nuclear Event. The battle to contain the contamination and avert a greater catastropheultimately involved over 500,000 workers and cost an estimated 18 billion rubles, crippling the Soviet economy. The disaster began during a systems test at reactor number four of the Chernobyl plant. Therewas a sudden power output surge, and when an emergency shutdown was attempted, a more extreme spike in power output occurred, which led to a reactor vessel rupture and a series of explosions. Theseevents exposed the graphite moderator of the reactor to air, causing it to ignite. The resulting fire sent a plume of highly radioactive smoke fallout into the atmosphere and over an extensivegeographical area, including Pripyat. The most severely contaminated areas of Belarus, Russia, and Ukraine.

Japan
A March 12 explosion at the earthquake-damaged Fukushima Daiichi nuclear power plant inOkuma, Japan, appears to have caused a reactor meltdown. However, the earthquake in Japan, in alcoolant system — appears to have damaged the containment facility, and the explosion almost certainly did.There have been reports of “white smoke,” perhaps burning concrete, coming from the scene of the explosion, indicating a containment breach and the almost certain escape of significant amounts ofradiation. At this point, events in Japan bear many similarities to the 1986 Chernobyl disaster.
