FAQs on Nuclear Energy: Fission & Nuclear Reactor Video Lecture - Physics Class 12 - NEET

1. What is nuclear fission?

Ans. Nuclear fission is a process in which the nucleus of an atom is split into two or more smaller nuclei, releasing a large amount of energy. This process is the basis for nuclear power and atomic bombs.

2. How does a nuclear reactor work?

Ans. A nuclear reactor works by initiating and controlling a sustained nuclear chain reaction. The reactor core contains fuel rods made of enriched uranium, which undergo fission and release energy. This energy heats up water or another coolant, which then produces steam to turn a turbine and generate electricity.

3. What are the advantages of nuclear energy?

Ans. Nuclear energy has several advantages, including its high energy density, which means that a small amount of fuel can generate a large amount of electricity. It produces a relatively low amount of greenhouse gas emissions compared to fossil fuels. Additionally, nuclear power plants can operate continuously and provide a stable source of electricity.

4. What are the risks associated with nuclear energy?

Ans. The main risks associated with nuclear energy include the potential for accidents or meltdowns, which can release harmful radiation into the environment. Improper disposal of nuclear waste can also pose a long-term environmental hazard. Furthermore, the proliferation of nuclear technology raises concerns about the spread of nuclear weapons.

5. How is nuclear waste managed?

Ans. Nuclear waste is managed through a combination of methods, including storage, reprocessing, and disposal. Currently, most countries store their nuclear waste in specially designed facilities, such as deep geological repositories. Some countries also reprocess spent fuel to extract usable materials and reduce the volume of waste. However, the long-term management and disposal of nuclear waste remain a significant challenge.
