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.

A general formulation of the boundary conditions for the commonly used radionuclide transport equation in the geosphere is shown. To evaluate the accuracy of a widely used approximation of the source boundary condition, considering convective flux alone and neglecting dispersive flux, both solutions for an idealized one-dimensional case are derived and compared. It is demonstrated then that the simpler boundary condition gives a good approximation for all cases with weak dispersion. This criterion is fulfilled for a wide range of parametric values, but the applicability of the simpler boundary condition always has to be checked.
