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 simplified but approximate method for the calculation of nuclear heating is described. Results using this method are compared with those of more rigorous calculations. The computational effort required is significantly reduced, and an accuracy generally better than ±20% can be achieved provided reasonable estimates of gamma-ray production are used. It would appear that the gamma-ray absorption coefficients used here are too low as a result of assuming average gamma-ray energies that are too high. As experience is gained with use of the method, greater accuracy should result from improved assumptions regarding both gamma-ray production and average gamma-ray energies.
