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.

To improve the accuracy of the after-shot plasma equilibrium reconstruction on Tore Supra, the previous EFIT code, which utilizes only magnetic measurements as a constraint (we shall call it EFIT-mag in the text), has been modified into EFIT-pol by taking the far infrared polarimeter measurements into account. With a correct choice of the input parameters (mainly for the P' and FF' polynomial orders and for the weights on Faraday angles), the results reconstructed by EFIT-pol are in good agreement with the experimental values deduced from the magnetic measurements as well as with the CRONOS code simulations. In this paper, after a brief description of the EFIT code, the approach used to parameterize EFIT-pol is presented, and the accuracy improvement is shown for a typical shot of Tore Supra, as well as through statistics on a database of 95 shots of different plasma currents and additional powers.
