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 measuring procedure for the determination of neutron activation cross sections averaged over the neutron spectrum of 252Cf is described. Measurements were done in a low-scattering irradiation facility that provides a nearly undisturbed field of neutrons emitted with the spontaneous fission of 252Cf The following neutron reactions were in vestigated: 113In(n,n′), 115In(n,γ), 115In(n,n′), 197Au(n,γ), and 197Au(n,2n). The resulting average cross sections were compared with those of other experiments. In addition, calculations of average cross sections were performed. The results of the present and of our earlier measurements were summarized and compared with calculated average cross sections obtained by folding the spectral distribution of 252Cf neutrons with different σ(E) data (ENDF/B-IV, ENDF/B-V, and recent experiments).
