  • to double the Chernobyl accident.

  • Noble acted Ellsworth.

  • Nuclear Accident Serious Cornell The damaged reactor fire has destroyed most of the reactor's core world's worst nuclear disaster.

  • Casually, rates are higher than those that have been announced by the Soviet Union so far.

  • We know next to nothing, and I don't think that they're going to accept international aid.

  • I don't know exactly what's happened.

  • The situation is under control.

  • Meltdown contaminated over half of Europe Radioactive fallout While the authorities scrambles to understand what was occurring, workers, engineers, first responders and local residents were abandoned to their fate.

  • Over 400 times.

  • More radiation was omitted that the bombing of heroes on signaled the beginning of the end of the Soviet Union.

  • In the Soviet Union, the question off acquiring nuclear technology was a matter off a major national pride.

  • After World War two, Soviet Union experienced a long period of political tensions with US.

  • The Soviet Union waas huge country that inherited the territory from the Russian Empire.

  • There was belief that the Soviet technology, and particularly nuclear technology or anything doing, for example, with space was superior to American.

  • The first Sputnik, it proved a point of tremendous importance.

  • The Sputniks were followed by space rockets.

  • The Soviets were the first to put a man into the orbit.

  • There wasn't believed that in some areas, in particular areas doing this nuclear and space they had off the U.

  • S.

  • Acted in a three Mile island brought home need to assure that nuclear power in the safest possible reactors don't explode.

  • They don't go into meltdown in the Soviet Union.

  • That's something that can happen only in the capitalist world.

  • Nuclear power appeared from military applications.

  • United States develop nuclear bomb, Soviet Union, develop nuclear born hwe, need nuclear reactors for military applications.

  • And we start with small ones in making 54 built a small plant for basically propaganda reasons, saying, OK, we're not like the United States.

  • We're trying to use the power off nuclear for peaceful purposes, but really didn't put any thought into that.

  • In terms of the economic development, Ukraine traditionally had a wide significant industrial capability call that they were getting at that time became more and more difficult to extract, so they were looking for other sources off energy.

  • They will lobby in Moscow for three nuclear power plants.

  • Moscow found money to build just one.

  • They found a location where land was not very productive.

  • It's close the border with Bill Russia.

  • It's forest.

  • They're stripping river there and that's where they built the nuclear power plant.

  • Chernobyl power complex lies about 120 kilometers north of Kiev, Ukraine.

  • In 1983 Chernobyl reactor number four was commissioned.

  • One of the requirements of getting the commission was that there be an experiment.

  • If there was loss of electricity to the cooling of that reactor turbines they're going to continue to spend.

  • And could they use that electricity to keep the water pumps going to cool the reactor for 30 cents?

  • Diesel generators are gonna do it, but it just takes him 30 seconds to build up enough energy.

  • They hadn't done that experience in order to do it.

  • He was going to take more time than what they had.

  • There was a bonus to be available if they finished that reactor prior to the end of 1983 kind of sign that they had done it, got their bonuses.

  • And three years later, April 1986 I decided to do that experiment.

  • At that time, the test that they were running.

  • It was supposed to be done during daytime reactor at another nuclear power plant in Ukraine went offline.

  • Agreed Operator called the plant and Saturday.

  • Guys, you're not supposed to shut down.

  • Just keep going until 11 p.m. They already started to slow down the reactor in preparation for the test on.

  • It was sitting in that situation for almost half of a day.

  • They didn't shut down the reactor.

  • Still, they turned off some of the, uh, six that would have automatically shut it down If you bring a reactor down low, they thought that they can handle the power level manual and appear to be not.

  • It took them longer than what they thought it went over into the next shift.

  • The post of midnight shift, arguably not the most experienced A shift to do this, they brought it down to low became actually unstable that it didn't respond in a normal way to the actions that the operators were taken.

  • Director said No, no.

  • Bring the control rods up and bring the power up on the reactor a little bit Maur so that we can conduct this experiment and they bring control rods up a bit and nothing sent.

  • Power of the reactors starts to come up.

  • Order was bringing the control rods back into the reactor.

  • Reactor is getting hotter and hotter, and the control rods are starting to come back in the channel's start to heat up.

  • And the control rods were stuck when cooling water was added instead of cooling things down when it hit the superheated fuel rods, it rapidly turned to steam on.

  • That caused an explosion with the heat of the reactor blew, Uh, the top had no containment vessel built over the top to try to contain any explosion or a massive release of radiation.

  • They cannot fully control the radioactive court.

  • A great deal radio activity has been released.

  • Radiation mediation mediation 500 times above normal in divinity of acidity.

  • I think I have to be evacuated.

  • There will be no effective way of protecting the pictures.

  • Show us a second major heat source.

  • Just because you had an explosion doesn't mean that vision stops.

  • It is burning.

  • The graphite is releasing very small radioactive particles.

  • In an effort, Thio put out the fire and also reduce the radiation.
