In a nuclear fission reaction a freely moving neutron?
In a nuclear fission reaction, a freely moving neutron undergoes neutron capture and initiates the nuclear fission of a fuel atom.
A nuclear fission reaction occurs when a U-235 nucleus is bombarded by a neutron the products are xe 143 3 neutrons and a strontium isotope?
There are many fission products, see the Wikipedia entry for 'Fission Product Yield'
How is a chain reactor controlled?
Since the continued chain reaction of a nuclear fission reactor depends upon at least one neutron from each fission being absorbed by another fissionable nucleus, the reaction can be controlled by using control rods of material which absorbs neutrons. Cadmium and boron are strong neutron absorbers and are the most common materials used in control rods. A typical neutron absorption reaction in boron is In the operation of a nuclear reactor, fuel assemblies are put into place and then the control rods are slowly lifted until a chain reaction can just be sustained. As the reaction proceeds, the number of uranium-235 nuclei decreases and fission by- products which absorb neutrons build up. To keep the chain reaction going, the control rods must be withdrawn further. At some point, the chain reaction cannot be maintained and the fuel must be replenished
What particle is used to start nuclear fission?
In actuality, a spontaneous fission event begins a nuclear chain reaction. It kick starts a nuclear chain reaction. And a neutron from that fission will initiate another fission to continue and rev up that nuclear chain reaction.
What causes fission?
Only certain elements are fissionable, or at least with practical means. The fission of for example the atom U235 happens when it is struck by a slow neutron, it splits, which is fission, releasing two smaller atoms and two or three neutrons (products). The products from the nuclear reaction weigh less then the original atoms. The difference in weight is converted into energy.

What does nuetron absorption accomplish in a nuclear reactor?
Neutron absorption is the key to the operation of a nuclear reactor as this is what perpetuates the chain reaction. Neutrons can be absorbed by a number of things within the core of an operating reactor, but when a fuel atom absorbs a neutron, it becomes unstable and fissions. The fission event releases fission fragments, energy, and more neutrons, which will, when absorbed, continue the chain reaction.
What controls the fission reaction within a reactor core?
High neutron capture elements (e.g Boron, Cadmium ) are used to control fission reaction.

What is a prompt fission?
A prompt fission is a fission that results from the immediate interaction, i.e. a prompt interaction, from a preceding interaction. There is no delay, or more correctly, neutron moderation, or any other intervening reaction, in a prompt fission reaction.
What particle is used to start nuclear fission?
In actuality, a spontaneous fission event begins a nuclear chain reaction. It kick starts a nuclear chain reaction. And a neutron from that fission will initiate another fission to continue and rev up that nuclear chain reaction.
What helps control the fission reaction in a nuclear plant?
The fission reaction is controlled through use of high neutron capture material as Boron, Gadolinium, Cadmium, ... etc.
What does initiation of nuclear weapons mean?
starting the fission neutron chain reaction using some kind of pulsed neutron source.
What is a fission nuclear reaction?
The primary result of a fission reaction is the conversion of mass to energy. In fission, the nucleus split, either through radioactive decay or as result of being bombarded by other subatomic particles known as neutrons.
