Nuclear Energy

Front

What is nuclear energy?

Back

Nuclear energy is the energy released during nuclear fission or fusion, especially when used to generate electricity.

Front

What is fission?

Back

Fission is the process of splitting the nucleus of an atom into two or more smaller nuclei, along with the release of energy.

Front

What is fusion?

Back

Fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process.

Front

What is uranium?

Back

Uranium is a heavy metal used as fuel in nuclear reactors due to its ability to undergo fission.

Front

What is radioactive waste?

Back

Radioactive waste is the material that remains after nuclear fuel has been used in a reactor, which is hazardous and must be managed carefully.

Front

What is a chain reaction in nuclear fission?

Back

A chain reaction occurs when the products of one fission event cause additional fission events, leading to a self-sustaining series of reactions.

Front

Why is nuclear energy considered a controversial topic?

Back

Nuclear energy is controversial due to concerns about radioactive waste, nuclear accidents, and the potential for nuclear weapons proliferation.

Front

What are the advantages of nuclear energy?

Back

Advantages include low greenhouse gas emissions, high energy density, and the ability to produce large amounts of electricity.

Front

What are the disadvantages of nuclear energy?

Back

Disadvantages include the risk of accidents, long-lived radioactive waste, and high costs of building and decommissioning plants.

Front

What is the role of neutrons in nuclear fission?

Back

Neutrons initiate the fission process by colliding with the nucleus of an atom, causing it to split.
