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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

In this study, computational fluid dynamics solutions are obtained for a General Atomics GT-MHR reactor core under a depressurization scenario involving highly compressible flow. It is found that while the FLUENT segregated solver is generally preferred for nuclear engineering applications, the coupled solver provides better performance at very high pressure ratios in this application.
