Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

A measuring device for measuring the mass flow of nonsteady-state two-phase flows has been developed based on the principle of rotating flow machines. Two versions of the device [true mass flowmeter (TMFM) 2.5 with a measuring range of 2.5 kg/s, and TMFM 50 with a measuring range of 50 kg/s] were used to study the measuring accuracy and the field use of the system. While the measurement errors of TMFM 2.5 are within ±2.2% of the maximum flow, it is possible with the TMFM 50 to reduce the measuring error to ±1.5% (quality x<l%) and ±0.5% (quality ≥ 1%). This implies that the accuracy in measuring two-phase mass flow is practically identical with that obtained in single-phase flow by familiar standard measuring techniques.
