Answer:
Step-by-step explanation:
Nuclear fission is the process of splitting an atomic nucleus into two or more smaller nuclei, accompanied by the release of a large amount of energy. This process is used in both atomic bombs and nuclear reactors, but there are significant differences in how the process is controlled and utilized.
Atomic bombs use nuclear fission to create an explosion. In an atomic bomb, a critical mass of highly enriched uranium or plutonium is rapidly assembled, causing a chain reaction of nuclear fission to occur. The energy released by the fission reactions in the bomb causes an explosive release of energy and radiation, leading to massive destruction.
On the other hand, nuclear reactors use nuclear fission to produce electricity in a controlled manner. The nuclear fuel, typically uranium or plutonium, is arranged in a way that prevents a runaway chain reaction, and a neutron-absorbing material is used to control the rate of the fission reactions. The heat generated by the fission reactions is used to produce steam, which drives turbines to generate electricity.
In summary, the difference between nuclear fission in an atomic bomb and in a nuclear reactor is primarily one of control. Atomic bombs use uncontrolled fission reactions to create a powerful explosion, while nuclear reactors use controlled fission reactions to produce electricity.
