Mechanisms Engineering Test Loop Facility

Argonne’s METL facility supports development of next-generation components and workforce for sodium fast reactors.

The Mechanisms Engineering Test Loop (METL) facility, established in 2010, is an intermediate-scale liquid metal experimental facility that provides purified R-grade sodium to various experimental test vessels to test components that are required to operate in a prototypical advanced reactor environment. Experiments conducted in METL significantly assist the development of advanced reactors.

Current capabilities that reside in the METL facility include:

  • 750 Gallons of Reactor Grade Sodium
  • Prototypic Reactor Temperatures of 650°C
  • 4 Test Vessels
  • 4 Additional Test Loops
  • 300 Heater Zones
  • 1000+ Sensors
  • 2 Operational Tanks with Ports for Experiments
  • Sodium Purification and Contamination Monitoring
