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.

Tokamak operation techniques to control the poloidal magnetic field using multivariable poloidal field coils (MPFCs) were applied to the Hitachi tokamak HT-2, Two problems encountered in operating a tokamak with MPFCs were identified: low-voltage startup and equilibrium control without interference. The key to their solution was accurate control of the poloidal magnetic field. To obtain multipole fields, a singular value decomposition was applied to a response matrix from the coil current to the magnetic flux value at the plasma surface region. The multipole fields are orthogonal bases of the poloidal field, and the interference was cleared using these modes. A control technique using the multipole fields was applied to control the null point position of the poloidal magnetic field during breakdown, which made it possible to get breakdown with a low loop voltage. During the flattop phase, good controllability without interference was obtained using the concept of a multipole magnetic field.
