The Chernobyl disaster
Pripyat, 1986 · “Three Days”
In the early hours of 26 April 1986, reactor No. 4 of the Chernobyl (Chornobyl) nuclear power plant exploded, about three kilometres from the town of Pripyat (Prypiat). The Short follows Natalia, a fictional hairdresser, and her daughter through the day and a half before the town was evacuated. This is the history behind it.
Many people who lived in Pripyat are alive today. This entry keeps to well-documented facts and says where the accounts disagree.

Reactor No. 4 exploded at 1:23 this morning. Nobody has told the town.

An ordinary spring day

Washing the streets
Street sweepers washed the roads with foam while officials quietly measured radiation.2 By the evening, levels were rising and an evacuation was being prepared.1
OKSANAMama, why are they washing the streets with foam?

Three days
Residents were told to pack for about three days. More than 1,000 buses carried roughly 50,000 people out; sources give 43,000 to 51,000.4
NATALIAThree days, they said. Take your coat. Hurry.
- Since 1986
An empty city
No one has lived in Pripyat since. A few people later returned to villages elsewhere in the zone, but not to the city.9
- The toll
Still disputed
The official early death toll is 31. Long-term estimates range from under 100 (UNSCEAR) to around 9,000 (a WHO projection) and higher, and remain disputed.8

Pripyat's new Ferris wheel was due to open on 1 May 1986.
It still stands, rusting, in an empty city.
Natalia is fictional. The Ferris wheel is real.
Every line, checked
Each line from the Short that makes a historical claim, beside what the record says.

Sunshine in April! The whole town is outside today.

Mama! Can we ride the new Ferris wheel on May Day?

Mama, why are they washing the streets with foam?
One detailed account describes street sweepers washing the roads with foam; other accounts mention water.2 Either way, the streets were being washed.
Medium
Something at the plant. They'd tell us if it was serious.
That afternoon, about 50,000 people left on more than 1,000 buses.
They were told: three days. No one has lived in Pripyat since.
It still stands, rusting, in an empty city.
Open question
Think about it
- Officials measured rising radiation for more than a day before the town was told. What might explain the delay, and what were the risks of waiting?
- Residents were told to pack for about three days. Why might officials have said that, and how would it change what people took with them?
- Sources give different numbers for people, buses and deaths. How should a historian handle numbers that disagree?
- Many people who lived in Pripyat are alive today. How should a story about a recent event be told differently from one about Pompeii?
