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 does the use of a neutron reflector enhance the efficiency of a nuclear reactor?
A neutron reflector enhances the efficiency of a nuclear reactor by reflecting neutrons back into the reactor core, increasing the likelihood of nuclear reactions and the production of energy. This helps sustain the chain reaction and improve the overall performance of the reactor.
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 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.
Which component within a nuclear reactor directs neutron bombardment?
The control rods within a nuclear reactor help direct neutron bombardment. By adjusting the position of the control rods, operators can regulate the rate of nuclear fission reactions and control the release of energy.
What does the neutronic reactor do?
A neutronic reactor is a type of nuclear reactor that uses a high-energy neutron chain reaction to generate power through the fission of atomic nuclei. This type of reactor is designed to maximize neutron interactions for efficient energy production.
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.
What is fission cross section in nuclear reactor?
The fission cross section in a nuclear reactor is a measure of the probability that a neutron will induce fission in a particular nucleus. It is a crucial parameter for determining the neutron flux and reaction rates within the reactor core. Different isotopes have different fission cross sections depending on their ability to undergo fission when struck by a neutron.
What is the purpose of boron in nuclear reactors?
Boron is used inside a nuclear reactor inside a control rod which is used to 'soak' up the neutrons inside the nuclear reactor, a control rod can be used to control the rate of fission inside a nuclear reactor.
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 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.
