To reproduce the measured branching ratio of symmetric and asymmetric fission events for the 238U(n,F) reaction, more fissions coming from neutron-deficient nuclei were assumed. The damping of the triaxial collective modes contribution to the level density at the SL-mode outer saddle was essential...
U-238 and U-235. Natural Uranium is 99.3% U-238 and 0.7% U-235. U-238 is such a poor neutron-induced fissioner, under any conditions, that we can correctly say it won't experience a chain reaction in any way,shape, or

Neutron nuclear data of 233U have been evaluated in the energy range from 10-5 eV to 20 MeV. Evaluated quantities are the total, fission, capture, elastic and inelastic scattering, (n,2n) and (n,3n) reaction cross sections, and the average numbers of prompt and delayed neutrons emitted ...
Radon is a decay product of uranium-238 and radium-226 that is widely distributed in rock, soil, and groundwater. From: Clinics in Chest Medicine, 2021 Featured on this page Chapters and Articles You might find these chapters and articles relevant to this topic. Uranium, Plutonium, and Rad...
a nuclear chain reaction occurs that may be explosive unless the reaction is slowed by a neutron moderator, absorbing them. As little as 15 lb (7 kg) of uranium-235 can be used to make an atomic bomb.[11] The first nuclear bomb used in war, Little Boy, relied on uranium fission, wh...
Research into nuclear energy is ongoing, especially into nuclear fusion: nuclear energy can also be released in a reaction that combines two atoms to form a larger atom. However, this reaction is much less controllable than a fission reaction.23 ...
to occur. It helps to think of a big circle of marbles as the protons and neutrons of an atom. If you shoot one marble — a single neutron — into the middle of the big circle, it will hit one marble, which will hit a few more marbles, and so on until a chain reaction ...
a nuclear chain reaction occurs that results in a burst of heat or (in special circumstances) an explosion. In a nuclear reactor, such a chain reaction is slowed and controlled by a neutron poison, absorbing some of the free neutrons. Such neutron absorbent materials are often part of reactor...
Today’s light water reactors, heavy water reactors, fast neutron reactors, high temperature reactors and kin all have their own fuel preferences as a result, with high-assay low-enriched (HALEU) fuel being the new hot thing for new reactor designs. Let’s take a look at what goes into ...
