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.

It is shown that an accurate determination of the fission rate in fuel elements can be obtained by the technique of solid-state track detectors. The method gives: (a) the radial variation and (b) the absolute value of the fission rate, by application of the measured value of the mean-path-length of the fission products in the fuel. The quality of the results is independent of the neutron spectrum during the irradiation. In a particular case (thermal flux), results deduced from measurements performed with solid-state track detectors are compared with those obtained by the fissile detector (activation) technique. The agreement is excellent.
