fission-track dating — Method of determining the age of a mineral that utilizes the damage done by the spontaneous fission of uranium 238, the most abundant isotope of uranium. The fission results in radiation damage, or fission tracks, that can be made visible by… … Universalium
Fission track dating — is a radiometric dating technique based on analyses of the damage trails, or tracks, left by fission fragments in certain uranium bearing minerals and glasses. Uranium 238 undergoes spontaneous fission decay at a known rate. The fragments emitted … Wikipedia
Fission product — Fission products are the atomic fragments left after a large nucleus fissions. Typically, a large nucleus like Uranium fissions by splitting into two smaller nuclei, along with a few neutrons and a large release of energy in the form of heat… … Wikipedia
Thermal history modelling — is an exercise undertaken during basin modelling to evaluate the temperature history of stratigraphic layers in a sedimentary basin.The thermal history of a basin is usually calibrated using thermal indicator data, including vitrinite reflectance … Wikipedia
thermal neutron — noun (physics) A neutron of very low speed and hence very low energy, responsible for various types of nuclear reaction, incl fission • • • Main Entry: ↑thermal … Useful english dictionary
Fission product yield — Nuclear fission splits a heavy nucleus such as uranium or plutonium into two lighter nuclei, which are called fission products. Yield refers to the fraction of a fission product produced per fission.Yield can be broken down by: #Individual… … Wikipedia
thermal neutron — ▪ physics any free neutron (one that is not bound within an atomic nucleus) that has an average energy of motion (kinetic energy) corresponding to the average energy of the particles of the ambient materials. Relatively slow and of low… … Universalium
Fission-fragment rocket — The fission fragment rocket is a rocket engine design that directly harnesses hot nuclear fission products for thrust, as opposed to using a separate fluid as working mass. The design can, in theory, produce very high specific impulses while… … Wikipedia
Fission fragment reactor — Similar to how the fission fragment rocket produces thrust, a fission fragment reactor is a nuclear reactor that generates electricity by decelerating an ion beam of fission byproducts instead of using nuclear reactions to generate heat. By doing … Wikipedia
Thermal reactor — A thermal reactor has moderating materials to reduce the speed of neutrons to low velocity thermal neutrons, so that uranium 235 will be more likely to fission when it is struck by the neutrons and fewer neutrons will be captured by uranium 238.… … Wikipedia
nuclear fission — fission (def. 2). [1885 90] * * * Division of a heavy atomic nucleus into two fragments of roughly equal mass, accompanied by the release of a large amount of energy, the binding energy of the subatomic particles. The energy released in the… … Universalium
