A thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs , a more compact size, a lower mass, or a combination of these benefits.
Physicist Edward Teller was for many years the chief force lobbying for research into developing fusion weapons.. The idea of using the energy from a fission device to begin a fusion reaction was first proposed by the Italian physicist Enrico Fermi to his colleague Edward Teller in the fall of 1941 during what would soon become the Manhattan Project, the World War II effort by the United ...
According to an audit by the Brookings Institution, between 1940 and 1996, the US spent $11.3 trillion in present-day terms [107] on nuclear weapons programs. 57% of which was spent on building nuclear weapons delivery systems. 6.3% of the total$, 709 billion in present-day terms, was spent on environmental remediation and nuclear waste ...
A pure fusion weapon is a hypothetical hydrogen bomb design that does not need a fission "primary" explosive to ignite the fusion of deuterium and tritium, two heavy isotopes of hydrogen used in fission-fusion thermonuclear weapons. Such a weapon would require no fissile material and would therefore be much easier to develop in secret than ...
The components of a B83 nuclear bomb used by the United States. This is a list of nuclear weapons listed according to country of origin, and then by type within the states. . The United States, Russia, China and India are known to possess a nuclear triad, being capable to deliver nuclear weapons by land, sea and
Specifically, nuclear fusion won't help the world reach its 2030 net-zero targets. It may start to come into play by 2050 . “I still think we're decades away,” Dominguez said.
The fusion process itself adds only a small amount of energy to the process, perhaps 1%. [1] The alternative meaning is an obsolete type of single-stage nuclear bomb that uses thermonuclear fusion on a large scale to create fast neutrons that can cause fission in depleted uranium, but which is not a two-stage hydrogen bomb.
This is in contrast to pure-fission weapons, which produce all of their yield from a neutronic nuclear fission reaction. The first thermonuclear explosion, and thus the first man-made burning plasma, was the Ivy Mike test carried out by the United States in 1952. All high-yield nuclear weapons today are thermonuclear weapons. [4]
