FAQs on Nuclear Energy Video Lecture - Physics for Class 10

1. What is nuclear energy?
Ans. Nuclear energy is the energy that is released during a nuclear reaction or nuclear decay. It is a form of energy that is generated by splitting the atoms of certain elements, such as uranium or plutonium, in a process called nuclear fission.
2. How is nuclear energy produced?
Ans. Nuclear energy is produced through a process called nuclear fission. In this process, the nucleus of an atom is split into two smaller nuclei, releasing a large amount of energy in the form of heat. This heat is then used to produce steam, which drives a turbine to generate electricity.
3. What are the advantages of nuclear energy?
Ans. Nuclear energy has several advantages. Firstly, it produces a large amount of energy from a small amount of fuel, making it highly efficient. Secondly, it does not produce greenhouse gases like fossil fuels, making it a cleaner source of energy. Additionally, nuclear power plants can operate continuously, providing a reliable source of electricity.
4. What are the risks associated with nuclear energy?
Ans. Although nuclear energy has its advantages, there are also risks associated with it. The main concern is the potential for accidents or meltdowns at nuclear power plants, which can release harmful radiation into the environment. Additionally, the disposal of nuclear waste is a challenge, as it remains radioactive for thousands of years and needs to be stored safely.
5. Is nuclear energy renewable?
Ans. No, nuclear energy is not renewable. While nuclear fuel can be extracted from uranium and plutonium, these elements are finite resources and will eventually run out. However, nuclear energy is considered a low-carbon energy source and can contribute to reducing greenhouse gas emissions.
