Nuclear holocaust essay

The fissioning primary emits X-rayswhich "reflect" along the inside of the casing, irradiating the polystyrene foam.

Polystyrene foam becomes plasma, compressing secondary, and plutonium sparkplug begins to fission. Unsourced material may be challenged Nuclear holocaust essay removed. There is very little detailed information in the open literature about the mechanism of the interstage.

The pressure due to the ablating material is calculated to be 5. The neutron bomb is a hydrogen bomb with an intentionally thin tamper, allowing as much radiation as possible to escape.

The crucial detail of how the X-rays create the pressure is the main remaining disputed point in the unclassified press.

When fired, the plutonium Pu or uranium U core would be compressed to a smaller sphere by special layers of conventional high explosives arranged around it in an explosive lens pattern, initiating the nuclear chain reaction that powers the conventional "atomic bomb".

In the United States, such knowledge can by default be classified as " Restricted Data ", even if it is created by persons who are not government employees or associated with weapons programs, in a legal Nuclear holocaust essay known as " born secret " though the constitutional standing of the doctrine has been at times called into question; see United States v.

The reflector seals the gap between the Neutron Focus Lens in the center and the outer casing near the primary. Such processes have resulted in a body of unclassified knowledge about nuclear bombs that is generally consistent with official unclassified information releases, related physics, and is thought to be internally consistent, though there are some points of interpretation that are still considered open.

Only close analysis of new and old batches revealed the nature of that impurity. At a bare minimum, this implies a primary section that consists of an implosion-type fission bomb a "trigger"and a secondary section that consists of fusion fuel.

The exact mechanism whereby this happens is highly classified. The surface of the pusher for the secondary is now so hot that it is also ablating or expanding away, pushing the rest of the secondary tamper, fusion fuel, and fissile spark plug inwards.

The nested spheres at the top are the fission primary; the cylinders below are the fusion secondary device. High-explosive fires in primary, compressing plutonium core into supercriticality and beginning a fission reaction.

Born secret is rarely invoked for cases of private speculation. This energy compresses the fusion fuel and sparkplug; the compressed sparkplug becomes critical and undergoes a fission chain reaction, further heating the compressed fusion fuel to a high enough temperature to induce fusion, and also supplying neutrons that react with lithium to create tritium for fusion.

This dry fuel, when bombarded by neutronsproduces tritiuma heavy isotope of hydrogen which can undergo nuclear fusionalong with the deuterium present in the mixture.

The official policy of the United States Department of Energy has been not to acknowledge the leaking of design information, as such acknowledgment would potentially validate the information as accurate. Although it is sometimes considered to be a separate stage, it should not be confused with a true tertiary stage.

The interstage is responsible for accurately modulating the transfer of energy from the primary to the secondary.

Thermonuclear weapon

December Edward Teller in Detailed knowledge of fission and fusion weapons is classified to some degree in virtually every industrialized nation.

If the Nuclear holocaust essay fission stage is omitted, by replacing the uranium tamper with one made of leadfor example, the overall explosive force is reduced by approximately half but the amount of fallout is relatively low.

For the W the gas expansion velocity is roughly kilometers per second and the implosion velocity kilometers per second. Ablation mechanism firing sequence.

Thermonuclear weapons may or may not use a boosted primary stage, use different types of fusion fuel, and may surround the fusion fuel with beryllium or another neutron reflecting material instead of depleted uranium to prevent early premature fission from occurring before the secondary is optimally compressed.

The Koon shot of Operation Castle is Nuclear holocaust essay good example; a small flaw allowed the neutron flux from the primary to prematurely begin heating the secondary, weakening the compression enough to prevent any fusion. It must direct the hot gases, plasma, electromagnetic radiation and neutrons toward the right place at the right time.

This would complete the fission-fusion-fission sequence. The use of fusion fuel to enhance the efficiency of a fission reaction is called boosting. The energy released by the primary compresses the secondary through a process called " radiation implosion ", at which point it is heated and undergoes nuclear fusion.

Theoretically by continuing this process thermonuclear weapons with arbitrarily high yield could be constructed. Tertiary stages are further fusion stages see belowwhich have been put in only a handful of bombs, none of them in large-scale production.

One of the best sources is a simplified diagram of a British thermonuclear weapon similar to the American W80 warhead. Without boosting, a large portion of the fissile material will remain unreacted; the Little Boy and Fat Man bombs had an efficiency of only 1. The fuel undergoing the fusion reaction emits a large flux of neutronswhich irradiates the U tamper or the U bomb casingcausing it to undergo a fission reaction, providing about half of the total energy.

It was first used in thermonuclear weapons with the W thermonuclear warhead, and produced at a plant in the Y Complex at Oak RidgeTennessee for use in the W Compressed and heated, lithium-6 deuteride fuel produces tritium and begins the fusion reaction. The pressure of radiation at the intensities seen in everyday life, such as sunlight striking a surface, is usually imperceptible, but at the extreme intensities found in a thermonuclear bomb the pressure is enormous.Chomsky, Said, Shahak, Schoenman, Halper Noam Chomsky's writings on Israel and Jews.

Chomsky's Links to the neo-Nazis: Some documents Chomsky Update: A thermonuclear weapon is a second-generation nuclear weapon design using a secondary nuclear fusion stage consisting of implosion tamper, fusion fuel, and spark plug which is bombarded by the energy released by the detonation of a primary fission bomb within, compressing the fuel material (tritium, deuterium or lithium deuteride) and causing a fusion reaction.
