It didn't explode. Three Mile Island's Nuclear Power Plant in Pennsylvania experienced an almost complete meltdown.
1986.
They explode with nuclear explosions.
1986
It exploded when the flame on the engine ran out of energy and flamed the Challenger.
The year of 1986
Never ever
It did explode, but this was due to a surge in steam pressure which blew off the top of the reactor, it was not a nuclear explosion as in a nuclear weapon.
1986
No, a nuclear weapon needs a specific geometry to detonate, and it has to be held in this position by very high explosives to keep it in this shape. In a nuclear reactor, if the reactor core goes critical then the force of the expanding coolant will blow the reactor apart, preventing a nuclear blast.
Chernobyl, in the Ukraine, was the site of a nuclear reactor fire and radiation leak on April 26, 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
Thankfully there haven't been many nuclear accidents, however when they do happen they can be severe the worst nuclear accident/disaster was the explosion of reactor No.4 at the Chernobyl Nuclear power plant in 1986 on April the 26th.
A Nuclear Reactor.
No. LLNL even tested several Uranium-Hydride bombs in the 1950s. Even though their computer models said the devices should explode, none gave a nuclear yield. One could use the waste from the reactor as a Radiological Weapon, but the reactor itself is not useful as a weapon.
The only one that has ever exploded to my knowledge was at Chernobyl in 1986, and this was due to a steam pressure surge during an experimental procedure that was badly planned and carried out. This type of reactor was unique to the Soviet bloc countries and is no longer built, though I think some may still be in operation.
An artificial nuclear reactor is a nuclear reactor that is created by man to utilize a nuclear reaction for energy, as opposed to natural nuclear reactors.
