Nuclear Reactions and Energy Concepts

Front

What is nuclear fission?

Back

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei, along with the release of energy.

Front

What is nuclear fusion?

Back

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

Front

What is the primary energy source in nuclear power plants?

Back

The primary energy source in nuclear power plants is the fission of uranium-235 (U-235) or plutonium-239 (Pu-239) nuclei.

Front

What is a nuclear chain reaction?

Back

A nuclear chain reaction is a series of reactions where the products of one reaction initiate further reactions, commonly seen in fission processes.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter; it is the total kinetic energy of particles in a substance.

Front

What are fission fragments?

Back

Fission fragments are the smaller nuclei produced when a heavy nucleus undergoes fission.

Front

What role do neutrons play in nuclear reactions?

Back

Neutrons can initiate further fission reactions by colliding with other fissile nuclei, sustaining a chain reaction.

Front

What is high-level nuclear waste?

Back

High-level nuclear waste is highly radioactive material produced as a byproduct of nuclear reactions, requiring careful long-term storage.

Front

How is high-level nuclear waste typically stored?

Back

High-level nuclear waste is often stored in ceramic glass within protective metal containers to prevent radiation leakage.

Front

What is the significance of achieving high temperatures in fusion reactions?

Back

High temperatures are necessary in fusion reactions to overcome the electrostatic repulsion between positively charged nuclei.
