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.

Secondary gamma-ray skyshine has been measured at an intense 14 MeV neutron source facility with a Hp-Ge detector used to investigate this mechanism. Many discrete gamma-rays due to (n, γ) reactions were observed in the spectrum. It was confirmed that in the evaluation of the secondary gamma-ray skyshine, a precise spectrum calculation down to thermal neutron is indispensable. On the other hand, there exists only a continuum spectrum up to 8 MeV with no discrete peaks in the real skyshine spectrum from the upper air. It was found that the continuum spectrum is composed of mainly Compton scattered gamma-rays. In the distance dependency measurement, the real skyshine contribution showed slow attenuation compared with the whole skyshine contribution. This means that with increasing distance from the facility the real skyshine contribution is gradually dominant, namely, it becomes more important in the skyshine evaluation.
