|
Heat is generated in a nuclear reactor (thermal) by
|
|
fusion of atoms of uranium.
|
|
|
fission of U-235 by neutrons.
|
|
|
absorption of neutrons in uranium atoms.
|
|
|
combustion of a nuclear fuel e.g. uranium.
|
Explanation:
Detailed explanation-1: -When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. This process is known as fission (see diagram below). Each time a U-235 nucleus splits, it releases two or three neutrons. Hence, the possibility exists for creating a chain reaction.
Detailed explanation-2: -Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity.
