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.

Energy and angular distributions of alpha particles from the bombardment of carbon foils with 14.1-MeV neutrons were measured with a magnetic spectrometer. The observations included alpha particles with energies above 1 MeV emitted at angles between 19 and 135 deg. The cross section for alpha-particle emission obtained by integrating over emission angle was 402 ± 46 mb. From these data and from evaluations of the elastic and inelastic scattering cross sections, a kerma factor (energy deposition) of 1.84 ± 0.16 × 10−9 cGy·cm2 was deduced. The present cross section for the 12C(n,n′3α) reaction is much lower than previous measurements.
