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.

According to the best understanding so far, Low-Energy Nuclear Reactions (LENRs) are the result of neutron-based electroweak interactions. They are a class of nuclear reactions that occur at or near room temperature based on Standard Model physics and can occur in condensed matter under mild macrophysical conditions. They differ from nuclear fission or fusion which rely on strong-force interactions. Unlike fission reactions, low-energy nuclear reactions do not produce nuclear chain reactions. Among novel concepts in nuclear energy research, LENRs are unique in that laboratory experiments have demonstrated the generation of net energy. The experimental research demonstrates the production of nuclear-scale heat and changes to atomic numbers and atomic masses of reactants.
