Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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.

Confinement magnetic field of a field-reversed-configuration (FRC) plasma is reduced by a factor of about 10 and plasma density is decreased by a factor of about 100 without lowering the temperature seriously by translating a theta-pinch produced FRC plasma axially into a large bore metal vessel. Reduced magnetic field brings the lower-hybrid frequency into a range easily detected by magnetic probes. Search for wave activities in the FRC plasma for a wide frequency range disclosed magnetic field fluctuations in the lower-hybrid-drift frequency range for the first time in the FRC plasma. The identification of the mode is not done yet but the fluctuation level is close to the values predicted by theories on the LHD instability. This fluctuation level is not large enough to account for the transport rate of the particles from the FRC plasma.
