2Fissionable material — A substance whose atoms can be split by slow neutrons. Uranium 235, plutonium 239 and uranium 233 are fissionable materials. California Energy Comission. Dictionary of Energy Terms …
3List of fictional elements, materials, isotopes and atomic particles — This list contains chemical elements, materials, isotopes or (sub)atomic particle that exist primarily in works of fiction (usually fantasy or science fiction). No actual periodic elements end in ite , though many minerals have names with this… …
4Nuclear fuel — Fissionable materials that have been enriched to such a composition that, when placed in a nuclear reactor, will support a self sustaining fission chain reaction, producing heat in a controlled manner for process use. U.S. Dept. of Energy,… …
5nuclear weapon — an explosive device whose destructive potential derives from the release of energy that accompanies the splitting or combining of atomic nuclei. [1945 50] * * * or atomic weapon or thermonuclear weapon Bomb or other warhead that derives its force …
6Fissile — In nuclear engineering, a fissile material is one that is capable of sustaining a chain reaction of nuclear fission. All known fissile materials are capable of sustaining a chain reaction in which either thermal or slow neutrons or fast neutrons… …
7actinide element — ▪ chemical element group Introduction any of a series of 15 consecutive chemical elements in the periodic table from actinium to lawrencium (atomic numbers 89–103). As a group they are significant largely because of their radioactivity.… …
8atomic bomb — 1. a bomb whose potency is derived from nuclear fission of atoms of fissionable material with the consequent conversion of part of their mass into energy. 2. a bomb whose explosive force comes from a chain reaction based on nuclear fission in U… …
9Nuclear weapon design — The first nuclear weapons, though large, cumbersome and inefficient, provided the basic design building blocks of all future weapons. Here the Gadget device is prepared for the first nuclear test: Trinity. Nuclear weapon designs are physical,… …
10Nuclear fusion-fission hybrid — Hybrid nuclear fusion fission (hybrid nuclear power) is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The concept dates to the 1950s, and was briefly advocated by Hans Bethe during the 1970s …
