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.

We are performing research and development to increase production quantity and yield for Inertial Fusion Energy targets for laser fusion. A key component of the laser fusion target is an approximately 4 mm diameter foam shell. To facilitate large-scale production, research into optimization of foam shell gelation and hardening times to reduce non-concentricity of the foam shell is underway. Additionally, we are examining methods to modify the current laboratory bench scale process for initial foam shell formation, various fluid exchanges, and sealcoat chemistry into a continuous process in collaboration with Schafer Corporation. The proposed process utilizes porous tubing sections to perform fluid exchanges in a long (200 m-1 km) continuous path of tubing extending from the triple orifice generator currently used to encapsulate and form the foam shell.Real-time process control has been applied to the triple orifice generator to control the diameter of the foam shell. The system makes use of a pair of photodiode sensors in a closed loop feedback control system incorporating a variable speed process pump. Empirical results indicate the process control loop is capable of identifying wet shell diameters to an approximate standard deviation of 80 to 90 m, on par with characterization results indicating true shell diameter standard deviations of 30-80 m.
