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 analysis of critical volumes of aqueous homogeneous solutions of uranium to aid in defining the 2200 m/sec neutron parameters for ENDF/B has been examined. The parameters for 233U and 235U are constrained by relating to the constant K obtained from the analysis of the critical systems. Here K is directly proportional to the hydrogen capture cross section at 2200 m/sec. This Note suggests that the capture cross section of hydrogen be removed from K and that a new constant K/σaH be defined by the critical systems. This new constant is the hydrogen-to-uranium ratio for an infinite critical system populated with neutrons having a Maxwellian energy distribution.
