What else can I help you with?
Are the number of atoms in space constant?
No. It is very frequent to change of the number of atoms in nuclear fissions and nuclear fusions.
Is nuclear chain reaction is called fusion?
No, a nuclear chain reaction refers to a self-sustaining series of nuclear fissions where the neutrons released in one reaction cause further fissions. Fusion, on the other hand, is the process of combining two light atomic nuclei to form a heavier nucleus, releasing large amounts of energy in the process.
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
Atoms are merged to produce this type of energy?
Nuclear energy.When the atoms are merged, the nuclear energy is a result of what is called Nuclear Fusion. When the atoms are split, the nuclear energy is a result of what is called Nuclear Fission.
Nuclear energy that is used to power nuclear powerplants?
Nuclear power plants generate electricity through nuclear fission reactions, where the splitting of uranium atoms releases energy in the form of heat. This heat is then used to generate steam, which drives turbines to produce electricity. Unlike fossil fuel plants, nuclear power plants do not emit greenhouse gases during operation.
What is a rapid series of nuclear fissions?
This might be called a chain reaction.
Are the number of atoms in space constant?
No. It is very frequent to change of the number of atoms in nuclear fissions and nuclear fusions.
Is fusion a chain reaction?
Not exactly, nuclear chain reactions are a series of nuclear fissions initiated by neutrons produced in a preceding fission.
Is nuclear chain reaction is called fusion?
No, a nuclear chain reaction refers to a self-sustaining series of nuclear fissions where the neutrons released in one reaction cause further fissions. Fusion, on the other hand, is the process of combining two light atomic nuclei to form a heavier nucleus, releasing large amounts of energy in the process.
What do all nuclear fission reactions produce?
All the nuclear fissions produce smaller elements from the larger element and few neutrons so that the fission reaction is continuously carried out.

What is nuclear reactors?
An assembly of fissile fuel (U-235 or PU-239) arranged in a geometric array. The assembly can be made to go critical such that a chain reaction starts which builds up a neutron flux inside the assembly. The chain reaction is controlled at a steady level using neutron absorbing control rods.The nuclear reactor can classified under:a thermal nuclear reactor, where the majority of fissions are caused by slow neutrons. In these reactors, the fast neutrons produced by fissions are slowed down with a moderator which can be graphite, heavy water or light water, anda fast nuclear reactor where the majority of fissions are caused by fast neutrons
Is nuclear fission soundless?
There is no sound emitted by the nuclear fissions themselves. Of course if the material is made into a nuclear weapon then there is a loud sound but this is due to the rapid release of energy causing a blast wave in the surrounding air, not the actual fission process itself.
Which form of energy results from the fission of uranium-235 nuclei that is used to generate electrical power?
Thermal energy is produced in the fuel by nuclear fissions.
Why do nuclear reactors require a fissionable isotope?
The fissionable isotope is required for the nuclear reactor operation. The fissionable isotope when fissions it give energy due to the mass difference according to Einstein formula E = mc2
What is a reactor?
A nuclear reactor is an assembly of fuel elements (uranium usually), a moderator which can be ordinary water, heavy water, or graphite, and control rods. The reactor is made to reach criticality when uranium fuel will produce a steady power output as a result of nuclear fissions which release heat. The heat is used to produce steam which feeds a conventional steam turbine/generating unit.
