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 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.
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.
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.
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.
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
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
Why does an atomic bomb explode?
It explodes because it contains a critical mass of unstable atoms of a heavy metal such as Uranium-235 or Plutonium-239. When the nucleus of one of these large atoms is hit by a neutron, the atom splits into two medium-size atoms such as Barium and Krypton or Strontium and Xenon, and also releases 2 or more free neutrons and a burst of energy. This process is called Nuclear Fission. The free neutrons from one nuclear fission can then create more fissions, and a Chain Reaction is begun. More fissions release more neutrons which create more fissions which release even more neutrons, etc. If conditions are right, this chain reaction proceeds explosively to form a Nuclear Fission Bomb or "Atomic Bomb". If this chain reaction is slowed and controlled, then the nuclear fission produces heat energy which can be used to boil water in a Nuclear Power Plant. Rapid fission, nuclear bomb. Slow controlled fission, nuclear power plant.
When was Rapid Transit Series created?
Rapid Transit Series was created in 1977.
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
