The neutron source in a typical reactor is Antimony pins inside beryllium sleeves The antimony emits gamma rays and the beryllium converts the gamma rays to neutrons. The neutrons place the in core instrumentation onscale so that criticality can be approached slowly and safely.

What is the purpose of the reactor chamber in a nuclear reactor?
neutron absorber
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 purpose of a reaction chamber in a nuclear reactor?
neutron absorber
What accomplishes the release of the nuclear energy in a reactor?
neutron chain reaction
What is the function of a nuclear reactor of a nuclear plant?
simply, the nuclear reactor is the source of heat (or steam) for the nuclear power plant.
How do they start a nuclear reactor?
With all control rods inserted all the way, begin inserting fuel rods.When the basic minimum operating number of fuel rods have been inserted, insert a continuous neutron source of known intensity.Measure the neutron flux in the reactor and calculate the reactor's neutron multiplication factor to determine how close you are to design predicted critical.Begin withdrawing control rods very slowly, stopping periodically and repeating step 3. Each time the neutron multiplication factor should increase.If the multiplication factor keeps increasing in step 4 while the control rods are stopped, you have reached critical. Remove the neutron source and the neutron flux in the reactor should decline slightly then become constant.You have now safely started your nuclear reactor. Congratulations!If anything unexpected happens reinsert all control rods, remove the neutron source, find and fix the problem, and restart the procedure.
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.
Are nuclear reactors and nuclear power plants the same?
Not really. It depends on what you are trying to do. A nuclear power plant is a power plant that uses a nuclear reactor as its source of energy. A nuclear reactor, on the other hand, is a more generalized term for a device that uses nuclear energy (specifically the release of binding energy from the Strong Atomic Force) to do something. In the general case, we use the reactor to generate energy for the power plant to use in generating electricity. Sometimes, we use the reactor for other, research type things, such as generating a neutron flux to study the physics of nuclide activation.
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.
