The basic process taking place in nuclear reactors is - |
| A. | Radioactivity |
| B. | Fission |
| C. | Fusion |
| D. | None of the above |
| Answer» B. Fission | |
|
Explanation: A nuclear reactor produces and controls the re-lease of energy from splitting the atoms of uranium, known as nuclear fission. When a fissile atomic nucleus such as uranium- 235 or plutonium-239 absorbs a neutron, it undergoes nuclear fission in which the heavynucleus splits into two or more lighter nuclei. The fission process produces free neutrons and gamma pho-tons, and releases a very large amount of energy. |
