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.

Using a large liquid scintillator as the fission neutron detector the number of prompt neutrons per fission, ν, for Th232 and U238 have been measured at neutron energies of 3.6 and 14.9 Mev. The values for U238 of 2.79 ± 0.09 and 4.75 ± 0.12 are in good agreement with earlier accurate measurements while the Th232 values of 2.42 ± 0.10 and 4.43 ± 0.13 agree with the results of Kuzminov et al. and of Leroy but not so well with that of Smith et al. The parameters of the equation (En) = (0) + a·En, where En is the neutron energy in Mev, have been obtained by fitting a straight line to the available data using the least mean square method yielding (En) = 1.87 + 0.177 En for Th232 and (En) = 2.30 + 0.154 En for U238.
