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 computational model is presented for infrared heating of frozen hydrogen layers in cryogenic ICF capsules. The model contains linked ray trace and heat conduction programs. The conduction part of the model has been validated with a cryogenic hohlraum experiment without infrared irradiation. The complete model has been used to design and analyze experiments on infrared layering of D2 in a hohlraum. The modeling provides an understanding of how to control the long scale length ice thickness perturbations by varying the infrared power balance and beam pointing. Based on the confidence developed in the model by comparison to experiment, design calculations are presented for IR layering systems for ICF ignition targets.
