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.

Fermilab center renamed after late particle physicist Helen Edwards
Fermi National Accelerator Laboratory’s Integrated Engineering Research Center, which officially opened in January 2024, is now known as the Helen Edwards Engineering Center. The name was changed to honor the late particle physicist who led the design, construction, commissioning, and operation of the lab’s Tevatron accelerator and was part of the Water Resources Development Act signed by President Biden in December 2024, according to a Fermilab press release.

The paper presents research results of permeability of hydrogen isotopes through CrNi35WTiAl alloy containing radiogenic helium, and results of hydrogen and radiogenic helium impact on mechanical properties of this alloy. The impact of hydrogen and radiogenic helium on mechanical properties of CrNi35WTiAl alloy was determined by tensile tests of cylindrical samples in inert and hydrogen atmospheres. For this research samples with various concentrations of 3He (90, 230 and 560 appm) were prepared. The buildup of 3He has been fulfilled using the “tritium trick” technique. Maximal influencing of hydrogen and radiogenic helium on mechanical properties of CrNi35WTiAl was observed at 873 K on samples with 560 appm of 3He. Testing of permeability of hydrogen isotopes was made in temperature range from 723 to 973 K.
