liquid metal reactor

Thân thiện

A liquid metal reactor uses molten sodium to cool its core.

Definition

1. Noun:
   • A nuclear reactor using liquid metal as a coolant: A liquid metal reactor is a type of nuclear reactor where the primary coolant is a liquid metal, such as sodium or lead-bismuth eutectic, instead of water or gas. This design allows for operation at higher temperatures and lower pressures than conventional reactors.

Usage Examples

• Noun:
  • The experimental liquid metal reactor demonstrated improved thermal efficiency.
  • Safety protocols for a liquid metal reactor differ from those of light-water reactors due to the coolant's properties.

Advanced Usage

• The term is often used in technical discussions about Generation IV reactor designs, where liquid metal coolants are studied for their potential advantages in safety and sustainability.
• It can appear in contexts comparing reactor coolant types, such as "gas-cooled," "water-cooled," or "liquid metal reactor."

Variants and Related Words

• LMR (abbreviation): A common acronym for Liquid Metal Reactor.
  • The LMR program was a significant research initiative.
• Sodium-cooled fast reactor (SFR): A prevalent type of liquid metal reactor using sodium as the coolant.
  • The SFR is a specific class of liquid metal reactor.
• Lead-cooled fast reactor (LFR): Another type using lead or lead-bismuth as the coolant.

Synonyms

• Liquid-metal-cooled reactor: A more descriptive synonym.
• Fast reactor (when context implies liquid metal coolant): Many, but not all, liquid metal reactors are designed as fast-neutron reactors.

Related Phrases

• Primary coolant loop: The system where the liquid metal circulates in a liquid metal reactor.
• Coolant chemistry: Refers to the management and monitoring of the liquid metal's purity and properties within a liquid metal reactor.
