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.

An approximate method for calculating the interference of neutron streaming between different regions (drawers) in fast critical assemblies is described by applying the well-known Benoist formula to super cell problems. The interference effect on the diffusion coefficient was numerically evaluated and the results are compared with those obtained by Yoshida’s method. Sodium void worths in control rod positions (control rod follower channel) relative to the sodium-filled channel are calculated on the basis of diffusion theory with the interference effect and compared with the results obtained from transport calculations. The comparison reveals that the inclusion of the interference effect improves the calculational accuracy remarkably.
