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.

Space-time neutronic behavior of CANDU reactors is of importance in the analysis and design of reactor safety systems. A methodology has been developed for simulating CANDU space-time neu-tronics with application to the analysis of postulated loss-of-coolant accidents. The approach involves the efficient use of a set of computer codes that provides a capability to perform simulations ranging from detailed, accurate three-dimensional space-time to low-cost survey calculations using point kinetics with some “effective” spatial content. A new space-time kinetics code based on a modal expansion approach is described. This code provides an inexpensive and relatively accurate scoping tool for detailed three-dimensional space-time simulations.
