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.

As for the modulation process of a traveling wave direct energy converter (TWDEC), which will be used in D-3He fusion power generation and has a principle of a reversal process of linear accelerator, numerical analysis of particle orbits has been performed. Space charge effect is taken into account to examine lower modulation effect found in simulation experiments. In the high incident particle density expected in the simulation experiments, the influences of space charge effect on modulation process have been confirmed in the view points of radial spread, axial velocity, and bunching characteristics.
