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 well-collimated T(d,n)4He fast neutron beam has been used to investigate the possibility of a precise measurement of the energy of fast neutrons using a 2- × 2-in. NE-213 liquid scintillator. Four sets of measurements were performed at 0-, 85-, 90-, and 95-deg nominal angles of the deuteron beam relative to the collimator axis. This experimental setup provides monoenergetic neutrons with nominal energies of 14.697, 14.115, 14.061, and 14.007 MeV, respectively. The results of the energy measurement of these monoenergetic neutrons are 14.718 ± 0.0292 MeV, 14.124 ± 0.0177 MeV, 14.072 ± 0.0144 MeV, and 14.028 ± 0.0155 MeV. The proton recoil spectra created in the liquid scintillator were unfolded with the FORIST unfolding code. The center of gravity of the measured neutron peak was assumed to be the value of the exact neutron energy.
