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.

The ratio of the fission cross section of 235U to the scattering cross section of 1H has been measured in the 1- to 6-MeV range using monoenergetic neutrons from a pulsed 3H(p, n)3He source. In this measurement, solid-state detectors determined fission fragment and recoil proton emissions from back-to-back U(99.7%) and polyethylene disks. Timing permitted discrimination against room-scattered neutron backgrounds. Absolute values for 235U(n, f) are obtained using the Hopkins-Breit evaluation of the hydrogen-scattering cross section.
