initially inside a nuclear reactor, uranium fuel such as uranium 235 is lowered inside the reactor and excess neutron is released, which is then absorbed by the uranium fuel and it atomically becomes unstable, so it splits into two smaller nuclei and more excess neutrons released. Again the same reaction occurs and splitting the nuclei into more smaller nuclei until it dies of or becomes atomically stable, the result of this is chain reaction.
What else can I help you with?
How is a fission reaction initiated and sustained?
A fission reaction is initiated by bombarding a heavy atomic nucleus, like uranium or plutonium, with a neutron. This causes the nucleus to split into two smaller nuclei, releasing more neutrons and a large amount of energy. To sustain the reaction, these released neutrons must continue to collide with other nuclei, causing them to split and release more neutrons, creating a chain reaction. This process is carefully controlled in nuclear reactors to generate heat for electricity production.
In a reactor what is nuclear energy produced in?
It is produced in the fuel rods by fission of the U235 nuclei. Each fission produces a certain amount of heat, and this is transferred to the water or gas which is pumped past the fuel, by contact heat transfer.
Fission is the splitting of an .?
Atom.
Can fission occur after fusion?
No, fission and fusion are two distinct nuclear reactions. Fusion involves the joining of atomic nuclei to release energy, while fission involves the splitting of atomic nuclei. They are not directly connected processes, so fusion does not lead to fission.
How is nuclear fission initiated in a nuclear reactor?
Nuclear fission in a nuclear reactor is initiated by bombarding uranium or plutonium atoms with neutrons, causing them to split and release more neutrons, which then continue the chain reaction.
Where does the nuclear enengy come from?
It comes from the fission of certain nuclei, mostly U235 and Pu239. Every fission of a nucleus of an atom of these materials releases a certain amount of energy as heat.
What are fission fragments?
When an atomic nucleus fissions, it splits into smaller atomic nuclei. These smaller atomic nuclei are referred to as "fission fragments." The unstable nucleus of a radioactive element can fission (split) into smaller nuclei, i.e. those of lighter elements. This can also release other atomic particles, as well as energy. In nuclear power and atomic weapons, the fission process is initiated to release the nuclear energy. Natural fission is a much rarer occurrence than radioactive decay.
What is the splitting of the nuclei called?
Fission.
The splitting of an atom's nucleus into two smaller nuclei is called?
The splitting of an atomic nucleus into smaller nuclei is called nuclear fission.
What term is use to describe splitting a large atomic nucleus into smaller ones?
Nuclear fission is defined as splitting large nuclei into smaller ones.
What is the process of the production of lighter nuclei from heavier nuclei called. Nuclear radiation nuclear force fusion or fission?
The process of producing lighter nuclei from heavier nuclei is called nuclear fission. This process involves splitting the nucleus of an atom into lighter fragments, releasing a significant amount of energy in the process.
How is a fission reaction initiated and sustained?
A fission reaction is initiated by bombarding a heavy atomic nucleus, like uranium or plutonium, with a neutron. This causes the nucleus to split into two smaller nuclei, releasing more neutrons and a large amount of energy. To sustain the reaction, these released neutrons must continue to collide with other nuclei, causing them to split and release more neutrons, creating a chain reaction. This process is carefully controlled in nuclear reactors to generate heat for electricity production.
What is the splitting of an atoms nucleus into two smaller nuclei is called?
nuclear fission
In a reactor what is nuclear energy produced in?
It is produced in the fuel rods by fission of the U235 nuclei. Each fission produces a certain amount of heat, and this is transferred to the water or gas which is pumped past the fuel, by contact heat transfer.
Are the nuclei lighter after nuclear fission?
Yes, the results of nuclear fission include the production of lighter nuclei. The originating atom has split into smaller pieces.
Why is it called Nuclear Fission?
It is called nuclear fission as in this process the heavy nuclei are split into fragments (or fission products).
How is nuclear energy formed?
Some nuclei, notably U235 and Pu239, can be made to cause a chain reaction where neutrons are produced in nuclear fission, and propogate more subsequent neutrons so that a steady rate of fissions can be achieved. Each fission releases an amount of energy in the form of heat, which is then used in generating plant similar to that in a fossil fuelled power plant.
