To insure the quality of their Nuclear stockpile and to test new designs, the US continues underground testing in Nevada. This is done at what is called the Nevada Test Site (formerly the Nevada Proving Ground), and it's located about 65 miles (105 kilometers) northwest of Las Vegas.

Currently the US does no actual nuclear weapons tests at any site. All tests are limited to computer simulations on custom designed very high speed supercomputers using carefully calibrated code based on previously performed nuclear tests and hydronuclear tests. Note: Hydronuclear tests are zero yield subcritical assembly tests that used to be performed by the US to precisely measure the very beginning of fission as well as verify safety of weapon designs.
All the facilities used by the US to prepare the materials for nuclear weapons, build nuclear weapons, design and test new nuclear weapons. This is all lead by the Department Of Energy.
The US signed the Comprehensive Nuclear-Test-Ban Treaty in 1996 which prohibits nuclear testing. Additionally, advancements in technology allow for testing through simulations and monitoring. The US also aims to set an example for other countries to follow suit in reducing nuclear proliferation.
Only on test sites.
Bikini Atoll in the Marshal island chain .
US weren't effected by the Nuclear Weapons, They created it.
The atoll used by the US for nuclear weapons testing is called Bikini Atoll, located in the Marshall Islands in the Pacific Ocean. The infamous Castle Bravo test, the largest nuclear weapon ever detonated by the US, took place there in 1954.
The UK was the third country to obtain nuclear weapons, after the US and the USSR. The UK had its first successful nuclear weapon test in October 1952, a plutonium warhead similar to the one dropped on Nagasaki.
to test nuclear weapons
No, the us no longer tests nukes.once the Cold War threat ended so did nuke testing and plants that made plutonium stopped production and stopped sending nuclear materials to bomb factories
the u.s. used non nuclear weapons and nuclear weapons against japan
The US no longer makes nuclear weapons, it only refurbishes existing ones that are wearing out.
The last U.S. above-ground (atmospheric) test was in 1963. The last U.S. underground test was in 1992. The Comprehensive Test Ban Treaty (signed by many major powers) ended testeing of all kinds, atmospheric or underground, in 1992. The U.S. models (with supercomputers) characteristics of nuclear weapons 'explosions' in order to 'test' its weapons designs.
