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.

A method for high fast neutron flux measurement using the reaction 93Nb(n,n')93mNb was tested. The method is based on measurement of niobium x rays. An average cross section over a measured 252Cf neutron spectrum was calculated and found to be = 1.88 ± 3% b. Here, 93mNb has a metastable level at 30 keV with a half -life of 13.6 yr. The branching ratio of the gamma rays emitted from this level was found to be ∼4%. The measurement was done by measuring the 16.52 + 16.62 keV niobium x-ray lines with an Si(Li) detector.
