What else can I help you with?
Is energy released from uranium 238 when the atom splits?
1. Energy (heat) 2. Fast neutrons 3. Fission products (atoms of other elements of lower atomic weight, often very radioactive). All three are produced simultaneously, for every fission that occurs.
A nuclear fission process in which neutrons produced by fission trigger more fissions?
nuclear chain reactionNote: there are also chemical chain reactions (e.g. polymerization), of course they involve no neutrons
Is moderation of neutrons always used to slow nuclear fission?
No, moderation of neutrons is not always used to slow nuclear fission. In some types of nuclear reactors, such as fast breeder reactors, fast neutrons are intentionally not moderated to slow down the fission process. These reactors operate using fast neutrons to sustain a chain reaction. However, in most commercial nuclear reactors, moderation of neutrons is employed to slow down the fission process and maintain a controlled chain reaction.
Nuclear fuels are bombared by what particles to induce their fission?
Nuclear fuels are bombarded by neutrons to induce their fission reaction. Neutrons are able to penetrate the nucleus of the fuel atoms and cause them to split, releasing energy and more neutrons in the process. This chain reaction is the basis for nuclear power generation.
What processes a molecule splits releasing neutrons and energy?
In nuclear fission it is the nucleus of the atom that splits, not a molecule, and this releases neutrons and energy. Reactions at the molecule level are termed chemical reactions, not nuclear, and these chemical reactions involve whole atoms and molecules.
What do nuclear fission release?
Large amount of energy and extra neutrons are released
Why are neutrons fired at the uranium nuclei?
Under bombardment with thermal neutrons a nuclear fission is produced with the isotopes 235U and 233U; a formidable energy is released after fission.
The process in which each split atom gives up neutrons?
The act of an atom splitting is called nuclear fission. In nuclear fission where we see neutrons emerge with fission fragments, and we then see those neutrons initiate other fission reactions is called a nuclear fission chain reaction.
How does the role of the moderater work in nuclear power plants?
The moderator in a nuclear reactor slows (moderates) the neutrons that are released during fission, so that they can subsequently cause fission in other atoms. When the neutrons are initially released, they tend to have too much energy, which impacts their ability to cause subsequent fission.
What is the processes of fission?
Energy is released when the the mass of the nucleus of an atom is reduced by the release of neutrons and gamma photons during the process of nuclear fission.
How is uranium made in to energy we can use?
Uranium-235 react with thermal neutrons in a nuclear reaction called fission. The enormous energy released by the nuclear fission can be transformed in electricity and heat in nuclear reactors.
How is nuclear fission initiated in a nuclear reactor?
Nuclear fission in a nuclear reactor is initiated by bombarding uranium or plutonium atoms with neutrons, causing them to split and release more neutrons, which then continue the chain reaction.
What is it called when neutrons released from a fission event cause other fission events in a continued self sustaining cascade?
This process is called a nuclear chain reaction. Neutrons released from one fission event trigger other fission events, creating a self-sustaining reaction that releases energy and more neutrons, continuing the chain reaction.
How do you use protons in nuclear fission?
Protons are not the active part in fission, they are just there. It is neutrons that determine the fission behaviour
Nuclear fuels are bombarded by what particles to induce their fission?
neutrons
