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 condensation models of the standard RELAP5/MOD3.2 code are assessed and improved based on a database that is constructed from previous experimental data of various condensation conditions. The RELAP5/MOD3.2 default model of laminar film condensation does not give any reliable predictions, and the alternative model always predicts values higher than those of the experimental data. Therefore, a new correlation based on the experimental data of various operating ranges is needed. The Shah correlation, which is used to calculate the turbulent film condensation heat transfer coefficients in the standard RELAP5/MOD3.2, gives good agreement with the database except for Kuhn's experimental data. The RELAP5/MOD3.2 horizontally stratified condensation model overpredicts both cocurrent and countercurrent experimental data. The Kim correlation predicts the database relatively well compared with that of RELAP5/MOD3.2.
