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.

The day, hour by hour

  1. 26 April · about 1:23 am

    Reactor No. 4 explodes

    An explosion destroyed reactor No. 4 of the Chernobyl plant, about three kilometres from Pripyat. It was the middle of the night.12

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

  2. 26 April · Saturday

    An ordinary spring day

    Residents were not told. It was a warm Saturday: children went to school, couples got married, and people were out in the streets.235

    NATALIA

    Sunshine in April! The whole town is outside today.

  3. 26 April · daytime

    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

    OKSANA

    Mama, why are they washing the streets with foam?

  4. 27 April · about 1:10 pm

    The announcement

    A radio announcement told residents to prepare to leave. Buses began loading from about 2 pm.45

  5. 27 April · afternoon

    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

    Natalia, afraid
    NATALIA

    Three days, they said. Take your coat. Hurry.

  6. 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

  7. 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.

Open question

Open question

Did the Ferris wheel ever turn?

Most sources say the wheel never carried a single passenger. Some say it ran for a few hours on 27 April, the day of the evacuation.67

Either way, it was built for May Day, and it is still standing. The Short only claims what everyone agrees on.

Contested

Think about it

  1. 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?
  2. 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?
  3. Sources give different numbers for people, buses and deaths. How should a historian handle numbers that disagree?
  4. Many people who lived in Pripyat are alive today. How should a story about a recent event be told differently from one about Pompeii?
