Nuclear explosions are not controlled. Nuclear reactors are controlled.The first controlled nuclear reaction in the US was on December 2, 1942.The first nuclear explosion in the US was on July 16, 1945.
The first nuclear meltdown in US history occurred in 1952 at the Chalk River Laboratories in Canada. However, the first nuclear meltdown on US soil occurred in 1959 at the Santa Susana Field Laboratory in California.
None ever recorded but I may happen soon. We'll see >:)
Three Mile Island, Pa, 1979
The USA started using nuclear energy in 1951
a meltdown
a meltdown
Controlled! ...if the reactor is working properly.
The chain reaction can be controlled, and it can be stopped. It is controlled in a nuclear power plant, and it is stopped when the plant shuts down, as it does periodically for refueling.
coz if nuclear meltdown it can explode
A controlled nuclear reaction is one in which the average number of reactions per second does not increase.
There was a naturally occurring nuclear reaction in a uranium ore deposit in Oklo, Gabon some 2 billion years ago. The reaction generated heat for more than a hundred thousand years with a potential of a meltdown. In recent history the Santa Susana Field Lab had reactor meltdown in 1959 EBR-I in Idaho had a meltdown on November 29, 1955. There were probably other meltdowns at the Idaho Reactor Test Site earlier in other test reactors (probably a good idea for a FOIA request).
It is a device where a controlled nuclear fission chain reaction occurs.

It created the first controlled nuclear reaction, as well as nuclear weapons.
A meltdown can occur in a nuclear reactor when there is too much current flow, causing the fuel rods to overheat. This can lead to a loss of control over the nuclear reaction and the release of radioactive material.
