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.
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.
The incident changed safety precautions throughout the world because it showed the world what could happen if a reactor did explode and what the effects would have been and the effects were devastating.
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.
It was on 26 April 1986 at 01:23:45 a.m. (Moscow time) that the number four reactor at the plant exploded. A link can be found below.
The Chernobyl Reactor is still active.
this was rote by amandaTHE Chernobyl Disaster was caused by a reactor.
the reactor accident at the chernobyl nuclear power plant.
No, nothing happened like melting of people in Chernobyl nuclear reactor accident.
chernobyl
the happenings in Chernobyl were that the nuclear reactor 4 blue up sending a plume of radiation over chernobyl killing lots of peeps
1986.
