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 set of laser implosion experiments were conducted at the OMEGA laser at the University of Rochester, Laboratory for Laser Energetics (LLE) to study the effect of 3He concentration in DT-filled target shells on fusion yield in ICF implosions. Eleven laser fusion shells consisting of 1100-m diameter, hollow, fused silica spheres with 4.6 to 4.7-m-thick walls were loaded with 520 kPa of deuterium-tritium (DT) and then with 3He (101.3 or 520 kPa). The 3He permeabilities of the shells were determined by measuring the pressure rate of rise into a system with known volume. A mathematical method was developed that relied on the experimental fill pressure and time, and the rate of rise data to solve differential equations using MathCAD to simultaneously calculate 3He permeability and initial 3He partial pressure inside the shell. Because of the high permeation rate for 3He out of the shells compared to that for DT gas, shells had to be recharged with 3He immediately before being laser imploded or "shot" at LLE. The 3He partial pressure in each individual shell at shot time was calculated from the measured 3He permeability. Two different partial pressures of 3He inside the shell were shown to reduce neutron and gamma yields during implosion.
