When to Use Deuterium?

Deuterium is used in heavy water moderated fission reactors, usually as liquid D₂O, to slow neutrons without the high neutron absorption of ordinary hydrogen. This is a common commercial use for larger amounts of deuterium.

For what purpose deuterium is used?

Uses of Deuterium

The deuterium atom is widely used in prototype fusion reactors. The deuterium atoms also have their application in military, industrial, and scientific fields. They are used as a tracer in nuclear fusion reactors in order to slow down the neutrons in heavy water moderated fission reactors.

Can we use deuterium as fuel?

Deuterium is used in a number of conventional nuclear reactors in the form of heavy water (D₂O), and it will probably also be used as fuel in fusion reactors in the future.
