Topic: Boosted fission weapon


  
  Nuclear weapon - Encyclopedia, History, Geography and Biography
For example, a boosted fission weapon is a fission bomb which increases its explosive yield through a small amount of fusion reactions, but it is not a hydrogen bomb.
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.

Fission bombs derive their power from nuclear fission, where heavy nuclei (uranium or plutonium) are bombarded by neutrons and split into lighter elements, more neutrons and energy.
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 to occur.
Additionally, most fusion weapons derive a substantial portion of their energy (often around half of the total yield) from a final stage of fissioning which is enabled by the fusion reactions.

 WE.177 - Encyclopedia, History, Geography and Biography
The WE.177A boosted fission weapon, deployed in 1971, was originally conceived as an Improved Kiloton Weapon to replace Red Beard a tactical kiloton-range bomb.
WE.177A was a dual-purpose weapon, being used by RAF and Royal Navy fixed wing aircraft as a surface attack tactical bomb against land and sea surface targets.
This stopgap weapon was WE.177B a thermonuclear parachute-retarded free-fall bomb based on a lengthened WE.177A casing, using as a thermonuclear primary the intended warhead for WE.177A.

A nuclear weapon is a weapon which derives its destructive force from nuclear reactions of fission or fusion.
Some weapons are designed for special purposes; a neutron bomb is a nuclear weapon that yields a relatively small explosion but a relatively large amount of prompt radiation; these could theoretically be used to cause massive casualties while leaving infrastructure mostly intact.
Weapons which are designed to actually be used on a battlefield in military situations are known as "tactical" weapons.

 Boosted fission weapon - Wikipedia, the free encyclopedia
Boosted fission weapons are a type of nuclear bomb that uses a small amount of fusion fuel to increase the rate, and thus yield, of a fission reaction.
In a traditional fission design, the fissile fuel is "assembled" quickly with conventional explosives, producing a supercritical mass.
A thermonuclear weapon of the Teller-Ulam configuration functions primarily by using a fission weapon external to the fusion fuel to compress the fusion fuel (rather than placing the fusion fuel in the same part of the weapon as the fission fuel, as in a boosted weapon).

 NTI: Ch2.4 - Nuclear Terrorism Tutorial
Nuclear weapons are explosive devices that rapidly release the energy produced from the fission or fusion of atomic nuclei.
Fission weapons were once commonly called "atomic bombs," and are the only type of nuclear weapon ever used in wartime.
In this type of weapon, the fission chain reaction creates the heat and pressure necessary to induce the nuclei of the hydrogen isotopes to initiate a fusion reaction, creating more energy and neutrons, which cause additional fissioning of the uranium or plutonium, thereby "boosting" the effectiveness of the fission reaction.

 Nuclear Weapon Physics and Design
A fission bomb is in a race with itself: to successfully fission most of the material in the bomb before it blows itself apart.
Fission, simply put, is a nuclear reaction in which an atomic nucleus splits into fragments, usually two fragments of comparable mass, with the evolution of approximately 100 million to several hundred million volts of energy.
The rod fissions at an accelerating rate as it, and the rest of the fuel capsule continue to implode and acts as the fusion "spark plug".

 NUCLEAR WEAPON DEVELOPMENT WITHOUT NUCLEAR TESTING?
It is natural for those involved in nuclear weapon develop- ment in the NWS to consider the designs of 30 to 50 years ago as obsolete, as indeed they are for their own purposes; but "obsolete" does not mean that these designs should be freely discussed or allowed to leak to non-NWS.
This chain breeding of neutrons and, consequently, fission of fissionable materials is terminated by hydrodynamic dis- assembly (expansion) of the system caused by the rapid en- ergy release or partial burning of fissionable materials.
As the nuclear weapon states see it in their national security interest to reduce the number of nuclear weapons held by others in the world (and perforce their own), they need the support of the other members of the NPT in order to preserve and universalize the non-proliferation regime.
