The USSR built and tested one with 52Mton yield and stated that it was designed for 100MTon yield but they reduced the amount of fusion fuel as they only needed to prove it could work and wanted to minimize damage and fallout from the test.
The largest nuclear weapon ever tested, the Tsar Bomba by the Soviet Union in 1961, had a blast radius of over 7 miles. The fireball created by the explosion measured around 2 miles in diameter and the shockwave was felt over 400 miles away.
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 largest nuclear plant meltdown happened at the Chernobyl Nuclear Power Plant in Ukraine on April 26, 1986. The explosion and subsequent fire released large amounts of radioactive material into the atmosphere, resulting in one of the worst nuclear disasters in history.
The biggest nuclear weapon ever tested was the Tsar Bomba, a hydrogen bomb detonated by the Soviet Union in 1961. It had a yield of 50 megatons, making it the most powerful nuclear weapon ever detonated.
The most powerful nuclear weapon ever detonated was the Russian "Tsar Bomba" in 1961. (50 Megatons) It had a yield of 100 megatons of TNT, but was reduced to avoid fallout. People 100 km away would have gotten third degree burns from the heat of the explosion.
The largest KNOWN nuclear weapon was made by the Soviet Union (Russia) and was called the "Tsar Bomba" (King of Bombs). It had a yield of ~50MT.
The U.S.A.
* Earthquake Richter 5.0 = 32 kilotons nuclear weapon, like was used at Nagasaki * Earthquake Richter 6.0 = 1 megaton nuclear weapon * Earthquake Richter 7.0 = 32 megaton nuclear weapon * Earthquake Richter 7.1 = 50 megaton nuclear weapon, Tsar Bomba, the largest nuclear weapon ever tested * Earthquake Richter 8.0 = 1 gigaton nuclear weapon, much larger than anything ever made
The meaning of the word nuclear weapon, is a weapon that has a nuclear warhead on it.
The largest nuclear bomb ever detonated was the Soviet Union's Tsar Bomba in 1961, which had a yield of 50 megatons. It was the most powerful nuclear weapon ever created and tested.
theoretically the yield of nuclear weapons is unlimited.
This nuclear weapon is called an atomic bomb or a nuclear bomb
The largest nuclear weapon ever tested, the Tsar Bomba by the Soviet Union in 1961, had a blast radius of over 7 miles. The fireball created by the explosion measured around 2 miles in diameter and the shockwave was felt over 400 miles away.
Nuclear weapon detonations
If by "bomb" you mean a conventional explosive weapon, then the nuclear weapon is more powerful.
Massive retaliation -apex
To prevent tough guys to play with the war. If we use the nuclear weapon, nobody will survive. Nobody should play with the war.
