What is fission and where does it occur in a nuclear reactor?
Nuclear ﬁssion is a process where the nucleus of an atom is split into two or more smaller nuclei, known as ﬁssion products. … Nuclear fission occurs with heavier elements, where the electromagnetic force pushing the nucleus apart dominates the strong nuclear force holding it together.
Where does nuclear fission occur?
Explanation: Nuclear fission can happen in a nuclear reaction. An example would be in nuclear power plants, where uranium is decayed into other substances. In this example, a neutron reacts with uranium-235 to give krypton-92, barium-141, and 3 neutrons.
How is a fission reactor different from a fusion reactor?
Both fission and fusion are nuclear reactions that produce energy, but the processes are very different. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.
What is nuclear fission?
Nuclear fission is a reaction wherein a heavy nucleus is bombarded by neutrons and thus becomes unstable, which causes it to decompose into two nuclei with equivalent size and magnitude, with a great detachment of energy and the emission of two or three neutrons.
What are the major components of nuclear reactor explain its functions?
Explain its essential parts with their functions. The essential components of a nuclear reactor are (i) fuel, (ii) moderator, (iii) control rod, (iv) coolant and (v) protection wall. (i) Fuel: A fissile material is used as the fuel.
