It is the absorption or capture of slow neutrons by the uranium nucleus that causes it to fission and release energy, so it is the essential factor that makes nuclear energy work

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.
How is californium used in nuclear reactors?
We might use californium as a neutron source in a nuclear reactor. Californium is a neutron emitter, and it can be used to "enhance" start-up abilities of a reactor where the fuel isn't as "good" as it might be in a core of, say, highly enriched uranium.
What is the function of the control rods in a nuclear reactor?
They are used in nuclear reactor to control the rate of fission of uranium and plutonium. Because these elements have different capture cross sections for neutrons of varying energies, the compositions of the control rods must be designed for the neutron spectrum of the reactor it is supposed to control.
The temperature levels in a nuclear reactor are maintained primarily by the use of what?
The control rods which are neutron absorbers can be raised or lowered to change the reactor power level. The temperature at the reactor outlet will be a function of both the power level of the reactor and the coolant flow rate and inlet temperature.
What is split a nuclear reactor to create energy?
The nuclei of U-235 and also Pu-239 (which is made by neutron absorption of U-238)
What is the purpose of the reactor chamber in a nuclear reactor?
neutron absorber

What accomplishes the release of the nuclear energy in a reactor?
neutron chain reaction
Is the nuclear reactor useful to made atom bombs?
Yes, the nuclear reactor can be useful when it comes to making nuclear weapons. Uranium can be lowered into the operating reactor and can be bathed in the neutron flux to become (through nuclear transformation) plutonium. Plutonium is ready to be shaped into the subcritical masses used in nuclear weapons.
What are the functions of a nuclear reactor components?
Mainly:Nuclear fuel: where nuclear fission and energy is producedReactor coolant: to extract heat from fuelReactor neutron moderator: to reduce neutron energy to thermal range (0.025 ev)Reactor control elements: to control nuclear reaction rate, compensate for fuel burnup, and for shutdown and safety conditionsReflector: to reduce neutron leakage

What is retentivity in nuclear energy?
You may mean 'reactivity'. In a nuclear reactor, this is the measure of how much above or below criticality the reactor state is, which effectively determines how fast the neutron flux increases or decreases.
In nuclear reactor how will you say control rods absorbs only one neutron?
Sorry, in any real nuclear reactor every control rod probably absorbs many moles of neutrons per second while the reactor is operating.
What is meant by chain reaction in nuclear reactor?
Basically a chain reaction (nuclear or chemical) is a self sustaining auto-catalytic reaction.In a nuclear reactor it is a neutron chain reaction, where each neutron released in every fission event can trigger another fission event. In a nuclear reactor the excess neutrons must be disposed of, which is the purpose of the control rods so that the reaction can be kept at some desired constant rate.
Where can you find einsteinium?
Einsteinium exist only in nuclear research centers (in USA or Russia) where a high neutron flux nuclear reactor is available.
What are the control rods in a nuclear reactor made of?
The control rods inside a nuclear reactor are made out of Boron.
