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 major difficulties encountered in controlling the steam generator water level swell and shrinkage are analyzed. A mathematical model based on the amount of steam generated by depres-surization during the periodic steam dump is used to predict the level changes. When the existing proportional integral controller is applied to the negative of these predicted level changes and the output is added to the controller output for the normal level error, it is found that the water level does not go down below the lower limit or up beyond the higher limit. This control algorithm is tested on a model steam generator, and the results show it is capable of handling the difficulties in the control of the level swell and shrinkage.
