Question

Main component of nuclear weapons ​

Answer 1

Answer:

Nuclear weapon designs are physical, chemical, and engineering arrangements that cause the physics package[1] of a nuclear weapon to detonate. There are three existing basic design types:

pure fission weapons, the simplest and least technically demanding, were the first nuclear weapons built and have so far been the only type ever used in an act of war (over wartime Japan).

boosted fission weapons improve on the implosion design using small quantities of fusion fuel to enhance the fission chain reaction. Boosting can more than double the weapon's fission energy yield.

staged thermonuclear weapons are essentially arrangements of two or more "stages", most usually two. The first stage is always a boosted fission weapon as above. Its detonation causes it to shine intensely with x-radiation, which illuminates and implodes the second stage filled with a large quantity of fusion fuel. This sets in motion a sequence of events which results in a thermonuclear, or fusion, burn. This process affords potential yields up to hundreds of times those of fission weapons.[2]

A fourth type, pure fusion weapons, is a purely theoretical possibility. Such weapons would produce far fewer radioactive byproducts than current designs, although they would release huge numbers of neutrons.

Pure fission weapons historically have been the first type to be built by new nuclear powers. Large industrial states with well-developed nuclear arsenals have two-stage thermonuclear weapons, which are the most compact, scalable, and cost effective option once the necessary technical base and industrial infrastructure are built.

Most known innovations in nuclear weapon design originated in the United States, although some were later developed independently by other states.[3]

In early news accounts, pure fission weapons were called atomic bombs or A-bombs and weapons involving fusion were called hydrogen bombs or H-bombs. Practitioners, however, favor the terms nuclear and thermonuclear, respectively.

Answer 2

Answer:

Nuclear Materials

Main components of nuclear weapons are the key ingredients in nuclear weapons. They include fissile, fussionable and source materials. Fissile materials are those which are composed of atoms that can be split by neutrons in a self-sustaining chain-reaction to release energy, and include plutonium-239 and uranium-235. Fussionable materials are those in which the atoms can be fused in order to release energy, and include deuterium and tritium. Source materials are those which are used to boost nuclear weapons by providing a source of additional atomic particles for fission. They include tritium, polonium, beryllium, lithium-6 and helium-3.
