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.

One method of production of low-density polymeric foams is to dissolve a monomer and a photo-initiator in a solvent and to polymerise by means of free radical polymerisation. The gel produced is precipitated in a non-solvent and subsequent super critical drying produces a low-density micro-porous foam. In some cases, the observed densities of the foam were significantly higher than expected. There is evidence to believe that this could be due to a chain transfer reaction to the solvent used in polymerisation.
