उत्तर
- In a nuclear power plant, uranium or plutonium are used as fuel.
- Conversion of nuclear energy to thermal energy during the nuclear fission process: During the fission of nuclei of atoms like uranium or plutonium, the nuclear energy is converted to thermal energy.
- Conversion of thermal energy to kinetic energy in steam: This thermal energy is used to heat the water present in a boiler. Steam of very high temperature and pressure is generated and directed on the blades of the turbine.
- Conversion of kinetic energy in steam to kinetic energy in turbine: The kinetic energy produced in the steam is then used to drive the turbine.
- Conversion of kinetic energy in the turbine to electrical energy: The turbine rotates the generator connected to it which in turn produces electrical energy.
