Transcript of Chernobyl Disaster

Chernobyl Disaster
Prior to 1986, the USSR spends large percentage of GDP on funding their military needs. Why???
Between 1970 and 1983, the soviets constructed 2 pressurized light-water reactors and 2 graphite moderated light-water reactors. The reactors, collectively known as the Chernobyl Power Complex, were situated near the Pripyat River, a tributary of the Dneiper, for cooling needs. About 3 km away from the reactor, in the new city, Pripyat, there were 49,000 inhabitants. The old town of Chernobyl, which had a population of 12,500, is about 15 km to the South-east of the complex. Within a 30-km radius of the power plant, the total population was between 115,000 and 135,000.

April 26th, 1986 Reactor 4 of the Chernobyl Nuclear Power Plant exploded
"...the explosion released at least 5% of the radioactive reactor core into the atmosphere..." - World Nuclear Association

"The disaster released at least 100 times more radiation than the atom bombs dropped on Nagasaki and Hiroshima." - Livescience.com

Explosion kills 2 immediately and 28 within the next couple of weeks. 800,000 men risked their lives by exposing themselves to radiation in order to contain the situation. 25,000 of these have died and 70,000 are disabled.
Thousands of people suffer from radiation poisoning for years to come.
"The Chernobyl accident was the product of a lack of "safety culture". The reactor design was poor from the point of view of safety and unforgiving for the operators, both of which provoked a dangerous operating state. The operators were not informed of this and were not aware that the test performed could have brought the reactor into an explosive condition. In addition, they did not comply with established operational procedures. The combination of these factors provoked a nuclear accident of maximum severity in which the reactor was totally destroyed within a few seconds."
