Definition

1. Noun:
   • Heavy water: Deuterium oxide is a form of water where the hydrogen atoms are replaced by deuterium atoms (a heavier isotope of hydrogen). It is used as a moderator and coolant in certain types of nuclear reactors.

Usage Examples

• Noun:
  • The nuclear reactor uses deuterium oxide as a neutron moderator.
  • Scientists analyzed the sample of deuterium oxide in the laboratory.

Advanced Usage

• Scientific Context: The term is primarily used in chemistry and nuclear physics. It is often discussed in relation to nuclear fission, neutron moderation, and isotopic studies.
  • The properties of deuterium oxide differ slightly from those of ordinary water.

Variants and Related Words

• Heavy water (n): A common synonym for deuterium oxide.
• Deuterium (n): The hydrogen isotope (with one neutron) that is a component of deuterium oxide.
• Light water (n): Ordinary water (H₂O), often contrasted with heavy water in scientific contexts.

Synonyms

• Heavy water: The most direct and commonly used synonym.

Related Phrases

• (To) moderate neutrons: A key function of deuterium oxide in nuclear reactors.
  • The reactor core is designed to use deuterium oxide to moderate neutrons effectively.
