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.

Total attenuation cross sections of several sugars have been measured for 133Ba photons in a narrow-beam geometry setup, by using a hyperpure germanium detector. The values are compared with the values calculated with the aid of a mixture rule based on Hubbell’s data for the individual elements. Based on the measured values for different sugars, a set of mean mass attenuation coefficients for sugars is given for the energy region of interest.
