At Chernobyl there was a steam explosion which blew off the top of the reactor followed by a fire due to the graphite moderator burning in air, and a huge amount of radioactive material was discharged, including fission products from the fuel. I'm not sure which fast reactor you are referring to, but certainly the incident did not involve massive catastrophic failure of the reactor vessel, or it would have become a world incident as Chernobyl did.
Chernobyl, in the Ukraine, was the site of a nuclear reactor fire and radiation leak on April 26, 1986.
In normal operation, virtually none. In a bad accident like Chernobyl, a great deal. Fortunately only one Chernobyl type disaster has ever happened.
As far as I know the last failure requiring a write off of the reactor was at Chernobyl in 1986.
It was caused during an experiment on the plant, when the reactor became unstable and this caused a surge in steam pressure which blew off the top of the reactor and ejected active material like fuel and graphite. There followed a reactor fire as the graphite moderator was exposed to the atmosphere.
The Chernobyl Reactor is still active.
No, the last reactor was shut down in December of 2000. However, they are still working of cleaning and removal today.
this was rote by amandaTHE Chernobyl Disaster was caused by a reactor.
1986
the reactor accident at the chernobyl nuclear power plant.
No, nothing happened like melting of people in Chernobyl nuclear reactor accident.
chernobyl
Chernobyl, however it was not a nuclear explosion. It was a steam explosion that blew the roof off the reactor building and ejected roughly a third of the reactor contents, followed by a graphite fire ignited when air hit the hot graphite moderator of the damaged reactor.
the happenings in Chernobyl were that the nuclear reactor 4 blue up sending a plume of radiation over chernobyl killing lots of peeps
Chernobyl started from an inherently unstable design, it's considered a breeder reactor, really good at making weapons grade plutonium but functionally unstable. The actual incident occurred during testing of the reactor to see how far it could be pushed.

The Three Mile Island incident in 1979 was a partial meltdown resulting from equipment malfunctions and operator errors, with no immediate fatalities and limited off-site impact. In contrast, the Chernobyl disaster in 1986 was a full-scale meltdown caused by a flawed reactor design and operator errors, resulting in immediate deaths, widespread radioactive contamination, and long-term health and environmental consequences.
