Many of you would like to visit Pripyat and do some sightseeing... Is there any other disaster site on your bucket list?

“We all know what happened next.”

No I don’t that’s why I’m here

This isn't an informative summary of the actual disaster, but is informative if you're interested in being a tourist.

The Chernobyl situation was such a depressing and sad moment in history. Not just the deaths and the fact that it left the city in ruins but the fact that Chernobyl was an evolving and forward looking city with high potential.

But it caused me to meet one of my best friends. She’s a Ukrainian girl she was born in Chernobyl but this incident caused her to move with her family a small city in Sweden called Gävle. There we meet in school. I helped her with her Swedish and she taught me how to play football/soccer.

Her parents died in cancer when she was just fourteen years old and my aunt adopted and took care of her. She moved away to a special university to get better at Football and I hope that one day my friend will become a professional.

The biggest blame for this disaster lies with the senior management of Chernobyl for a few reasons.

(1)- Plant director Viktor Bryukhanov was under constant pressure to ensure that Reactor #4 would be finished on schedule so that substantial communist party bonuses could be won. To do so he was forced to use tar [highly flammable] to coat the roof of the reactor.

(2)- The Soviet Union’s Atomic Energy Commission did not make aware the fact that the reactors themselves were fatally flawed: they were dangerous to run at lower power levels. (KGB documents showed that from 1979 to 1986 authorities ignored repeated warnings of the danger at Chernobyl.)

But the biggest problem is this:

(3)- Although Leonid Toptunov is 2nd-in-command for the control room of Chernobyl’s Reactor #4 neither he nor control room foreman Aleksandr Akimov was in charge. Safety test preparations were instead overseen by the plant’s Deputy Chief Engineer Anatoly Dyatlov who gave the order for the test to be only carried out at a power level of 200 megawatts (USSR AEC test regulations STRICTLY set a minimum power level of 700 megawatts for the test) but Dyatlov assumes his position [Chief Engineer Nikolai Fomin was asleep in Pripyat during this critical test.] allows for him to set any parameters as he wishes, even for safety tests.

Needless to say; when problems were first spotted, the men did take steps to prevent the disaster. When Akimov noticed the power surge he immediatly did what his training told him to do: hit the emergency shutdown button. (Soviet nuclear reactor emergency shutdown buttons are given the name AZ-5) but again, the USSR AEC hid one tiny fact from the knowledge of plant workers.

(4)- The AZ-5 button automatically lowers the boron control rods into the reactor to try and stop the nuclear reaction ASAP, but the power levels shot up hundred-folds after that. This is because the boron control rods themselves are tipped with graphite (same stuff they use for the block that houses the fuel rods) which increases power, NOT reducing it.

Chernobyl is not a city... it's Pripyat ...

[radoslavstoyanov]

50 percent of the video is not about what the title says. But rather about boring trivia.

[persephonessong]

The HBO miniseries really does an excellent job at explaining everything i was moved at the end it brought me to tears all the suffering and pain...
