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.

Important problems in fusion technology and fusion materials research whose investigation requires intense fast neutron sources are surveyed. The most urgent tasks concern the investigation of 14-MeV neutron radiation damage in the first wall and other structural components of future fusion reactors and the development of low-activation materials. The needs of neutron sources according to energy range, neutron intensity, flux and fluence, and the scope of present capabilities are outlined for this special field of applications.
