ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

The Godunov method that tracks nonstationary fronts and interfaces as boundaries of subregions moving with time is extended to include radiation transport. In each subregion and at each time step, a new grid is created by use of boundary-fitted coordinates. The radiation transport is performed in a multiangle-multifrequency approach. The numerical method is based on a finite volume method in the space time-domain, and the hydrodynamic fluxes are calculated using the solution of Riemann problems. Numerical results are shown for some selected problems to demonstrate the efficiency of this approach.
