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.

Magnetized target fusion (MTF) promises to ease the power and intensity requirements for a fusion driver. High gain MTF targets require fusion ignition to occur in the magnetized fuel. Ignition requires the energy deposited by the charged fusion reaction products to exceed that lost from the plasma by a variety of loss mechanisms. We have used single particle tracking through a magnetized plasma to obtain preliminary results on the DT alpha particle deposition as a function of the plasma ρR and BR for a uniform spherically symmetric volume with a uniform Bθ magnetic field. More complicated plasma density, temperature, and field distributions can be handled by the code, including 2-D distributions, but the efficiency of this approach makes extensive calculations impractical. A more efficient approach is needed, particularly for use in dynamic calculations. However, particle tracking is useful for obtaining information for building more accurate models of the deposition for use in survey codes.
