How is a nuclear fission reaction controlled in a nuclear reaction?
A fission reaction is a chemical reaction wherein the atom gets split to generate energy. The most commonly used controlled form of this is in splitting Hydrogen for producing energy in nuclear reactors. It is also used in weaponry such as Hydrogen Bombs which have much greater power than in nuclear fusion reactions.
What is the difference between fission reaction in an atomic bomb and fission reaction in a nuclear power plant?
Nuclear fission is what takes place in a nuclear power station. When nuclear fission happens it is usually in a controlled environment and cause a chain reaction. If this chain reaction were to get out of hand then radiation could seep out and damage the environment and people surrounding. It must be handled correctly which can be costly and when decommissioned must be done correctly which can cost. However nuclear fission produces a lot of…
The fission process in a nuclear reactor which produces the thermal energy used in the steam cycle, is called a chain reaction because nuclei of U-235 and Pu-239 fission on absorbing a neutron, and the fission causes further neutrons to be released, thus a self sustaining reaction is started which is controlled to run at a steady power level.
If For a sustainable fission reaction each fission must produce exactly additional fission reaction(s).?
What is the name given to a situation in what one fission reaction instigates exactly one more fission reaction?
The nuclear reactor is the device where it occurs a controlled nuclear fission chain reaction. The nuclear fission reaction results in loss of mass (or mass defect) that transforms into energy according to formula E = mc2 (c is light velocity). The resulting energy manifests itself as heat energy that produces steam. The steam spins the turbines that spins electric generators and hence producing electricity.
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…
How many neutrons are produced during a typical uranium fission reaction and what is the role of these neutrons in a nuclear chain reaction?
A typical uranium fission event produces 2 to 3 neutrons. These neutrons are moderated (slowed down) and go on to initiate the fission of more uranium. On average, in a controlled reaction that is maintained at normal criticality (KEffective = 1), each fission creates exactly one neutron that is used to produce another fission.
