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.

In this paper, numerical simulation methods are used to study issues related to the optimal operating modes of hyperspeed (rotor velocity 1000 m/s and above) model gas centrifuges (GCs) of various lengths and velocities of rotation. The possibility of gas extraction under optimal conditions is studied using three-dimensional modeling. It is shown that for hyperspeed GCs with the Pitot tube as gas extractor, simultaneous attainment of the optimal values for both friction power and waste flux, which are necessary for achieving the optimal operating mode, is unattainable, unlike GC models with a rotor velocity of 600 m/s. It is also shown that the working gas within the shockwave generated by the gas extractor can attain temperatures exceeding 1300 K, which raises the question of a possible accelerated decomposition of uranium hexafluoride.
