  Nuclear weapon - Wikipedia, the free encyclopedia
A nuclear weapon is a weapon that derives its energy from the nuclear reactions of fission and/or fusion.
The detonation of a nuclear weapon is accompanied by a blast of neutron radiation.
Nuclear weapons have been at the heart of many national and international political disputes, and have played a major part in popular culture since their dramatic public debut in the 1940s, and have usually symbolized the ultimate ability of mankind to utilize the strength of nature for destruction.

 Nuclear weapon
Weapons which have a fusion stage are also referred to as hydrogen bombs or H-bombs because of their primary fuel, or thermonuclear weapons because fusion reactions require extremely high temperatures for a chain reaction to occur.
Nuclear weapons are often described as either fission or fusion devices based on the dominant source of the weapon's energy.
The distinction between these two types of weapon is blurred by the fact that they are combined in nearly all complex modern weapons: a smaller fission bomb is first used to reach the necessary conditions of high temperature and pressure to allow fusion to occur.

 Atomic Weapons Establishment - Wikipedia, the free encyclopedia
The Atomic Weapons Establishment, Aldermaston (formerly the Atomic Weapons Research Establishment, Aldermaston) is situated in the UK, just 7 miles north of Basingstoke and approximately 14 miles south-west of Reading, Berkshire, near a village called Aldermaston, bordering with Tadley.
Other Atomic Weapons Establishment sites could be found at Burghfield and Cardiff, the former Royal Ordnance Factories, although Cardiff is now closed.
The main output of this facility is that of plutonium fissile materials for the use in nuclear warheads.

 Atomic Audit: The Costs and Consequences of U.S. Nuclear Weapons Since 1940 Introduction   (Site not responding. Last check: 2007-09-11)
Atomic Audit is the first comprehensive effort to tally the total costs of the U.S. nuclear weapons program, from developing and deploying nuclear weapons to managing and ultimately disposing of the wastes created in the process.
Given the significant sums expended on nuclear weapons and their central role in the cold war, it is striking that so few have expressed interest in either the cumulative or the annual costs.
Proponents of the belief that nuclear weapons kept the cold war cold frequently ignore or discount the impact of much larger U.S. expenditures on conventional forces (see figure 2) and the fact that these forces, in contrast to nuclear weapons, were used in actual combat (for example, in Korea and Vietnam).

 NSC-68, Beginning Section VIII
In the event the USSR develops by 1954 the atomic capability which we now anticipate, it is hardly conceivable that, if war comes, the Soviet leaders would refrain from the use of atomic weapons unless they felt fully confident of attaining their objectives by other means.
For although the United States probably now possesses, principally in atomic weapons, a force adequate to deliver a powerful blow upon the Soviet Union and to open the road to victory in a long war, it is not sufficient by itself to advance the position of the United States in the cold war.
The first is to eliminate the atomic capabilities of the United States; the second is to prevent the effective mobilization of the superior potential of the free world in human and material resources; and the third is to secure a withdrawal of United States forces from, and commitments to, Europe and Japan.

The energy released by the spark plug ignites the fusion reaction, leading to the main energy release in the weapon.
In this levitated pit design, the thin outer shell of plutonium is driven inward by the explosive charge at velocities of several kilometers per second.
Because of size considerations, yields would probably be limited to a kiloton or less and, in such things as artillery shells, the device would be a cylinder rather than a sphere.

Meanwhile, the U.S. national weapons laboratories, with the support of some in Congress, are hard at work refining existing warheads and designing entirely new weapons, with a special emphasis on those able to attack and destroy hardened and deeply buried targets.
Fortunately, of the hundreds of attempted smuggling transactions involving radioactive materials that have been thwarted since 1991, the vast majority involved materials that were not weapons usable or were of insufficient quantity to construct a nuclear weapon.
The increase in the number of smuggling attempts in recent years serves as a clear warning that surplus nuclear weapons and weapons materials may not be entirely secure.

The basic principle of the fusion weapon (also called the thermonuclear or hydrogen bomb) is to produce ignition conditions in a thermonuclear fuel such as deuterium, an isotope of hydrogen with double the weight of normal hydrogen, or lithium deuteride.
It may also be a missile weapon, operated by muscle power (as with the javelin, sling, and bow and arrow), mechanical power (as with the crossbow and catapult), or chemical power (as with the rocket and missile and such guns as the cannon, rifle, and pistol).
Weapons may also be classified as conventional, destroying by kinetic energy (as with the bullet) or by chemical energy (as with the bomb and grenade).

Russia has already begun to emphasize the importance of its arsenal of nuclear weapons to compensate for its limited conventional capabilities to deal with hostilities that appear to be increasing along its borders.

The most important role for our nuclear weapons is to serve as a “sobering force,” one that can cap the level of destruction of military conflicts and thus force all sides to come to their senses.

Negotiations over the country's suspected atomic weapons dragged on, but an agreement was reached in June 1995 that included a provision for providing the North with a South Korean nuclear reactor.
In late December, North Korea expelled UN weapons inspectors from the country and announced it could no longer agree to the terms of the nuclear Non-Proliferation Treaty (NPT), officially withdrawing from it in January 2003.
At a third round of negotiations on North Korea's nuclear weapons program in June 2004, the U.S. offered North Korea the delivery of heavy fuel oil and a “provisional security guarantee” if it agrees to disclose details of its weapons program, allow inspections, and begin to dismantle its nuclear program within three months.
