Correct, the Chernobyl nuclear power plant did not have secondary containment structures in place to prevent the leakage of radioactive materials in the event of a nuclear accident. This lack of secondary containment contributed to the widespread environmental contamination following the Chernobyl disaster in 1986.

The #4 reactor is the reactor at the Chernobyl Nuclear Power Plant (Pripyat, Ukraine) that exploded on April 26, 1986. It is still the worst nuclear accident to ever take place anywhere.
Chernobyl was a thriving city with a population of around 14,000 people before the nuclear accident in 1986. It was home to schools, shops, and cultural facilities. The city also had a nearby nuclear power plant that provided employment for many residents.
The Chernobyl disaster occurred near the city of Pripyat, which is in the northern part of Ukraine. Pripyat was established to house workers of the Chernobyl Nuclear Power Plant, and it was the nearest city to the plant. The catastrophic nuclear accident took place on April 26, 1986, leading to widespread radioactive contamination in the surrounding areas, including Pripyat. Today, Pripyat remains largely abandoned and is part of the Chernobyl Exclusion Zone.
There was no famous disaster (or anything else) at Chernobyl in Russia as there is no such place. However for the disaster that occurred in Chernobyl in the Ukraine, please see the related question.
