What is the purpose of Fuel Rods in a Nuclear Power Plant?

Back

To keep the fuel in a well-defined geometry and provide a barrier.

Front

What is half-life in nuclear chemistry?

Back

The time required for half of the radioactive atoms in a sample to decay.

Front

If the half-life of uranium-232 is 70 years, how many half-lives will it take for 10 g of it to be reduced to 1.25 g?

Back

3 half-lives.

Front

What is fission in nuclear chemistry?

Back

The process of splitting a heavy nucleus into two lighter nuclei, releasing energy.

Front

What is fusion in nuclear chemistry?

Back

The process of combining two light nuclei to form a heavier nucleus, releasing energy.

Front

What are gamma rays?

Back

High-energy electromagnetic radiation with no mass.

Front

What is alpha decay?

Back

A type of radioactive decay where an atomic nucleus emits an alpha particle (2 protons and 2 neutrons).

Front

What is beta decay?

Back

A type of radioactive decay where a neutron is transformed into a proton, emitting a beta particle (electron or positron).

Front

What is a nuclear reaction?

Back

A process in which the structure of the nucleus of an atom changes, resulting in the release or absorption of energy.

Front

What is a chain reaction in nuclear chemistry?

Back

A series of reactions where the products of one reaction initiate further reactions.
