Chernobyl, Ukraine, 1986
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.
The Chernobyl disaster took place in 1986.
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 Chernobyl accident occurred in Ukraine, specifically at the Chernobyl Nuclear Power Plant near the town of Pripyat. The disaster took place on April 26, 1986, and is considered one of the worst nuclear accidents in history. It released large quantities of radioactive particles into the atmosphere, affecting not only Ukraine but also neighboring countries and regions across Europe.
The disaster occurred on On 26 April 1986 at 01:23:40 a.m, in the then USSR, It is now located in Ukraine, a former soviet state.
The United Kingdom has had several nuclear 'incidents', but never a full-fledged 'disaster' of the scope and scale of Chernobyl. The worst that comes to mind was the fire that took place at the Sellafield plant (then called Windscale) - http://www.sonicbomb.com/modules.php?name=News&file=article&sid=76&mode=thread&order=0&thold=0
Those reactions that take place in functioning nuclear reactors (i.e not Chernobyl or Fukushima when the accidents happened).
