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.

An investigation room to interrogate packages and baggage at airports, based on a neutron-induced gamma-ray method, was designed using the MCNP5 Monte Carlo radiation transport code. A pulsed neutron generator source of interval time responses 10 μs turned on and 100 μs turned off was used for the investigation. Gamma-ray emissions in the forward, scattering angle of 90 deg, and backward directions were detected in the two cases of neutron generator (turned on/turned off). The detected data revealed that gamma rays in the forward direction have a signal-to-background ratio higher than the other positions. In addition, thermal neutron capture detected in the turned-off interval showed larger numbers of good signal-to-background ratio than that in the turned-on interval. The results show that the detection of gamma rays induced with a pulsed neutron source can be applied as a basic technique in airports to identify smuggled illicit materials.
