Fission Neutrons

Some articles on fission, neutron, neutrons, fissions:

Teller–Ulam Design - Basic Principle
... minimum, this implies a primary section which consists of a fission bomb (a "trigger"), and a secondary section which consists of fusion fuel ... The primary is thought to be a standard implosion method fission bomb, though likely with a core boosted by small amounts of fusion fuel (usually 50/50% deuterium/trit ... bomb has already mastered the ability to engineer boosted fission ...
Liquid Fluoride Thorium Reactor - Disadvantages
... it is more difficult to separate plutonium fluoride from lanthanide fission products ... The primary loop salt contains the decay heat generating fission products, so these help to keep the salt hot and liquid ... Furthermore, after start up, the fission process in the primary fuel salt will produce highly radioactive fission products that produce a high gamma and neutron radiation field ...
Nuclear Weapon Design - Nuclear Reactions - Fission
... When a free neutron hits the nucleus of a fissile atom like uranium-235 ( 235U), the uranium splits into two smaller atoms called fission fragments, plus more neutrons ... Fission can be self-sustaining because it produces more neutrons of the speed required to cause new fissions ... of dozens of different ways, as long as the atomic weights add up to 236 (uranium plus the extra neutron) ...
Liquid Fluoride Thorium Reactor - Breeding Basics
... The first is a small amount of fissile, which splits ("burns") when hit by neutrons, releasing a large amount of energy and also releasing two or three new neutrons ... It must first absorb one of the 2 or 3 three neutrons produced in the fission process, which is called neutron capture, then it becomes a fissile isotope by radioactive decay ... today's reactors use the mined uranium-plutonium cycle in a moderated neutron spectrum ...
Nuclear Fission - Physical Overview - Energetics - Input
... The fission of a heavy nucleus requires a total input energy of about 7 to 8 MeV to initially overcome the strong force which holds the nucleus into ... The result is two fission fragments moving away from each other, at high energy ... About 6 MeV of the fission-input energy is supplied by the simple binding of an extra neutron to the heavy nucleus via the strong force however, in many fissionable isotopes, this amount ...

Famous quotes containing the word fission:

    The pace of science forces the pace of technique. Theoretical physics forces atomic energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced—by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.
    Erich Fromm (1900–1980)
