The Springfield Nuclear Power Plant is a two-unit pressurized water reactor nuclear power plant owned by Mr. Burns and is the main source of power in Springfield. Contents [ show ] Profile The plant is notorious for being poorly maintained, largely due to owner Charles Montgomery Burns ' miserliness and safety director Homer Simpson's incompetence.

Nuclear weapon design The Trinity test of the Manhattan Project was the first detonation of a nuclear weapon, which lead J. Robert Oppenheimer to recall verses from the Hindu scripture Bhagavad Gita: Weapons whose explosive output is exclusively from fission reactions are commonly referred to as atomic bombs or atom bombs abbreviated as A-bombs.

This has long been noted as something of a misnomeras their energy comes from the nucleus of the atom, just as it does with fusion weapons. In fission weapons, a mass of fissile material enriched uranium or plutonium is forced into supercriticality —allowing an exponential growth of nuclear chain reactions —either by shooting one piece of sub-critical material into another the "gun" method or by compressing using explosive lenses a sub-critical sphere of material using chemical explosives to many times its original density the "implosion" method.

The latter approach is considered more sophisticated than the former, and only the latter approach can be used if the fissile material is plutonium.

The amount of energy released by fission bombs can range from the equivalent of just under a ton to upwards oftons kilotons of TNT 4. Many fission products are either highly radioactive but short-lived or moderately radioactive but long-livedand as such, they are a serious form of radioactive contamination if not fully contained.

Fission products are the principal radioactive component of nuclear fallout. The most commonly used fissile materials for nuclear weapons applications have been uranium and plutonium Less commonly used has been uranium Neptunium and some isotopes of americium may be usable for nuclear explosives as well, but it is not clear that this has ever been implemented, and their plausible use in nuclear weapons is a matter of dispute.

Thermonuclear weapon The basics of the Teller—Ulam design for a hydrogen bomb: The other basic type of nuclear weapon produces a large proportion of its energy in nuclear fusion reactions. Such fusion weapons are generally referred to as thermonuclear weapons or more colloquially as hydrogen bombs abbreviated as H-bombsas they rely on fusion reactions between isotopes of hydrogen deuterium and tritium.

All such weapons derive a significant portion of their energy from fission reactions used to "trigger" fusion reactions, and fusion reactions can themselves trigger additional fission reactions.

Whether India has detonated a "true" multi-staged thermonuclear weapon is controversial. Almost all of the nuclear weapons deployed today use the thermonuclear design because it is more efficient. In the Teller-Ulam designwhich accounts for all multi-megaton yield hydrogen bombs, this is accomplished by placing a fission bomb and fusion fuel tritiumdeuteriumor lithium deuteride in proximity within a special, radiation-reflecting container.

When the fission bomb is detonated, gamma rays and X-rays emitted first compress the fusion fuel, then heat it to thermonuclear temperatures. The ensuing fusion reaction creates enormous numbers of high-speed neutronswhich can then induce fission in materials not normally prone to it, such as depleted uranium.

Each of these components is known as a "stage", with the fission bomb as the "primary" and the fusion capsule as the "secondary". In large, megaton-range hydrogen bombs, about half of the yield comes from the final fissioning of depleted uranium.

This technique can be used to construct thermonuclear weapons of arbitrarily large yield, in contrast to fission bombs, which are limited in their explosive force.

Most thermonuclear weapons are considerably smaller than this, due to practical constraints from missile warhead space and weight requirements.

Other types Main articles: Boosted fission weaponNeutron bombRadiological warfareand Antimatter weapon There are other types of nuclear weapons as well. For example, a boosted fission weapon is a fission bomb that increases its explosive yield through a small number of fusion reactions, but it is not a fusion bomb.

In the boosted bomb, the neutrons produced by the fusion reactions serve primarily to increase the efficiency of the fission bomb.Information on nuclear energy and the nuclear fuel cycle from the World Nuclear Association.

Nuclear power lesson plans and worksheets from thousands of teacher-reviewed resources to help you inspire students learning. Horizon Nuclear Power is a UK energy company developing a new generation of nuclear power stations.

A wholly owned subsidiary of Hitachi,Ltd., we plan to provide at least 5,8 00MW of new power station capacity to the UK, enough to power around 11 million homes. In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei).The fission process often produces free neutrons and gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.
