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.

Hydrogen isotope release properties of boron coated carbon tiles from JT-60U were investigated through secondary ion mass spectroscopy (SIMS). X-ray photoelectron spectroscopy (XPS) analysis of boron layer made by He+B10D14 method with 43 nm in thickness showed that the B/(B+C) ratio was about 0.9. Hydrogen isotopes in the boron layer and in the carbon layer were released at above 573 K and 1023 K, respectively. This means that hydrogen isotopes in the boron layer on the carbon tiles in JT-60U are released at temperatures as low as 573 K. The He+B10D14 boronization method is clearly effective to attain the high purity deuterium plasma and the low recycling because this method does not introduce H during boronization process. Wall conditioning before boronization is important because hydrogen retained in the carbon is released during plasma discharge through boron coating.
